Full textAbstract:
Recent studies of the environmental Kuznets curve raise questions regarding the relationship between environmental indicators and GDP and the fundamental reasons that explain this relationship. In response, this thesis presents one-sector and two-sector models to analyze the alternative causal relationships between an environmental indicator and GDP at different stages of economic development. These models analyze how economic scale, technology, preferences, and economic structure influence the causality and shape of the relationship. These theoretical studies are followed by two empirical studies. The first tests the causal relationship between CO2 emissions and GDP in Canadian manufacturing industries. The second explores several factors as the fundamental causes that influence the CO2 emissions in the same industries. Factors, such as economic scale, preferences, technological progress, structural change, and energy input, are found to be crucial in the determination of CO2 emissions. The empirical results are positive, but there are data limitations. The empirical studies can be re-evaluated as more data becomes available.

Full textAbstract:
I consider the influence of foreign environmental policy on domestic manufacturing activity using theory and empirics. A tractable three-country spatial model yields a theory of locational com- parative advantage in the production of pollution-intensive manufactured goods: greater market access to countries with stringent environmental policy encourages output in the polluting sector. Operationalizing the model empirically, I find robust evidence that high market access to countries with stringent environmental policy increases manufacturing value added. Both the theoretical and empirical analyses suggest that estimates of the Pollution Haven Effect that ignore third country environmental policy - yet make the stable unit treatment value assumption - can be misleading. Chapter Two We investigate the impact of short-term weather and long-term climate on self-reported life satisfaction using panel data. We find robust evidence that day-to-day weather variation impacts life satisfaction by a similar magnitude to acquiring a mild disability. Utilizing two sources of variation in the cognitive complexity of satisfaction questions, we present evidence that weather bias arises because of the cognitive challenge of reporting life satisfaction. Consistent with past studies, we detect a relationship between long-term climate and life satisfaction without individual fixed effects. This relationship is not robust to individual fixed effects, suggesting climate does not directly influence life satisfaction. Chapter Three This chapter considers the related policy challenges of deindustrialisation and 'leakage' which can arise when environmental regulation is differentiated across regions. A dynamic two-region 'New Economic Geography' (NEG) model is adopted in which agglomeration forces may make firms tolerant of regulatory disadvantage. Each region ratifies an international environmental agreement (IEA) requiring it to tax transboundary pollution created by local firms. In contrast to previous NEG studies, the model adopted is considerably more tractable, enabling comparative static analysis to be conducted analytically rather than through computer simulation. The model is extended to consider the relationship between the prescribed tax rates and deindustrialisation caused by the relocation of firms. Firm relocation in response to a given tax differential depends crucially on trade costs and the initial location (configuration) of industry. For some industry configurations, agglomeration forces are strong and a set of tax differentials exist which cause no international relocation of polluting firms. For other initial industry configurations in which agglomeration forces are weaker, the same set of tax differentials may cause complete inter-national relocation to the less stringently regulated region. Trade liberalization can actually make industry less likely to relocate in response to a regulatory disadvantage. The model is further extended to consider the issue of carbon leakage, which arises in the regulation of greenhouse gas (GHG) emissions. For relatively low tax differentials, agglomeration forces create rents which tend to anchor industry in the higher taxing region, avoiding carbon leakage. If the tax differential is too great, however, agglomeration forces cause all firms to relocate to the lower taxing region where they optimally emit more GHGs. Environmental outcomes may therefore be improved by reducing the tax rate in the higher taxing region in order to discourage industry relocation. When industry is diversified between regions, firms respond to higher (lower) relative domestic taxes by increasing (decreasing) output and polluting more (less).

Full textAbstract:
The purpose of this study was to assess the status of worksite smoking policies in Indiana's manufacturing industries and to describe the relationship between policy, workforce size, and manufacturing type. Of the 493 questionnaires distributed, 181 (36.7%) were returned. Approximately 67% percent of the industries reported having some type of restrictive policy with the majority of those policies not allowing smoking at the worksite except in designated areas. Most policies were developed within the last five years and were implemented due to a concern for employee health. Workforce size was directly related to the prevalence of significant restrictions. Those companies employing greater then 100 employees were the most likely to have a policy whereas the employing less than 11 were the least likely to have a policy. Standard industrial classifications 34 (fabricated metal products) and 35 (machinery, except electrical) had less restrictive policies as compared to other S.I.C. classifications. A follow up on 10% (n=30) of the nonrespondents yielded similar results to those who did respond.Department of Physiology and Health Science

Full textAbstract:
Unplanned and rapid growth of tourism can be perilous to the natural and socio-cultural environment of communities and regions. Unplanned tourism can destroy the unique landscapes upon which it depends. This problem is particularly severe in third world nations which are hosting a new generation of tourism in hopes of economic survival.This paper presents a case study which supports the above contentions by identifying changes that have taken place in Negril, Jamaica, through a discussion of the causes and effects of rapid, poorly planned tourism development in that town. This provides the basic framework within which the author raises questions suggest ideas to promote more appropriate and culturally and sensitive changes in present land use policies in the city of Negril.Department of Landscape Architecture

Full textAbstract:
Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2017.This research study investigates how environmental tools such as Resource Efficiency and Cleaner Production (RECP) can contribute to sustaining and supporting economic growth in South Africa. Resource optimisation is crucial when considering the concept of sustainable development. It also contributes to addressing the challenges of global warming and climate change, which in turn threaten industrial growth and sustainability in the long term. The study places emphasis on the barriers that prevent industry from implementing RECP recommendations, and identifies opportunities that could potentially reposition businesses should they consider implementation. It also promotes other sustainability tools that are available through collaboration with international entities, and this could be of great benefit to the South African industry. Factors of unemployment and urbanisation restricts national growth to some degree, hence the study explores how RECP can contribute to job retention by introducing new resource optimisation methodologies for the manufacturing sector, Moreover, it examines the imbalance between the demand as well as limitations of these resources. Through the compilation of data collated from questionnaires completed by industry, government and civil society participants, this study looks at achieving a balance between environmental sustainability and growth. It also looks at aligning this balance with the integration of specific economic and environmental policies, which also includes social aspects. What comes through significantly in this research is the lack of awareness within industry in terms of RECP, as well as the importance of prioritising the uptake of environmental initiatives to ensure that industry is compliant with the stringent policies and legislation designed by government to drive the sustainability process. Consequently the study shows that communication between public and private sector, as well as the awareness raising and marketing of sustainability to consumers need to be improved. An analysis of the various government support mechanisms is conducted, in respect of how industry could potentially leverage growth and drive positive change within their businesses. In addition to RECP, emphasis is placed on other Sustainable Consumption and Production (SCP) initiatives and tools that could possibly entrench sustainable practices and help with their incorporation into their business strategies.

Full textAbstract:
There is a growing concern from government, communities, civil society and mining companies on the sustained development of the impact of mining on communities and the benefits of mineral development. Communities are more vocal in expressing their expectations for benefits and on the other hand mines are concerned about profits and maintaining a social licence to operate. This study critically evaluates the impact mining has on socio-economic development in mining communities. The focus area of the study is the West Rand District Municipality in Gauteng Province, South Africa. The ‘impact’ refers to the mine’s contribution to infrastructure development and poverty reduction projects in areas where the mine is operating and sourcing labour from. Forecasts for better performance in the future will be assessed. Issues such as community consultation, identification of projects, development forums, the Integrated Development Plan (IDP) and partnerships are addressed. The literature was reviewed from existing national and international research on the topic. The study starts from two assumptions. The first is that minerals are potentially a great resource of wealth for poor countries. The second assumption is that minerals have the potential to benefit the local population through the creation of indirect employment, skills transfer, enhancing the capacity of health and education services, improved infrastructure and small and medium business opportunities. Poverty levels are viewed on a national and international scale. The study reveals problems, with existing approaches, on mine community development. It concludes that the impact of mining on infrastructure development and poverty reduction projects can be huge, but only if a variety of demanding preconditions are met. The study concludes that the reality of mineral led development in mine communities has not lived up to a roaring promise.

Full textAbstract:
Energy is essential to economic prosperity and quality of life. However it can have detrimental effects on the environment if not used properly. Moreover, if energy resources are scarce in a given country, then its use will impose economic and financial burdens on the national economy. The cement industry is energy-intensive, which adds a micro dimension to the macro issues mentioned above. Reducing energy consumption without due consideration to production requirements is not an optimal situation. What is needed is to arrive at a situation whereby energy is used rationally. The concept of rational use of energy has two embedded principles. The first is increased energy-use efficiency and the second is environmental protection. Jordan Cement Factories (JCF), located in a developing country where energy resources are not indigenously available and, therefore, costly energy requirements are imported, have realised the importance of addressing the energy management and conservation issues. This thesis describes the efforts initiated and conducted by the author, to address the research problem of improving energy usage through the application of effective management techniques aimed at reducing energy consumption per unit of cement produced. This present research has been concerned with energy management and efficient use of energy. The Jordan Cement Factories were used as a vehicle to demonstrate the proposed research methodology that aimed at improving energy consumption and thus operational efficiency. The methodology is based on establishing statistically significant relationships between interacting problem factors, and assessing the economic impact of improving these factors. Economic evaluation entailed the development of economic models and an application methodology combined with illustrative case studies. Consequently, the problem of energy management has been presented in a wider perspective that addressed the whole management system at the organisation. Towards that end, it was first necessary to show the significance of energy cost with respect to the overall manufacturing costs. The analysis of production costs, which demonstrated the significance of energy costs, was followed by the investigation and examination of the basic management factors that have direct impact on energy consumption at the JCF. Among these factors are, for instance, production line availability, production rate, average number of stoppages, and average duration of stoppages. These factors were determined using preliminary data analysis and the experience and technical knowledge of the researcher. The statistical analysis proved the existence of strong relationships between energy consumption and management factors. Several models were developed for a set of selected production lines, in the JFC at Fuhais and Rashadiya plants. These statistical models were generated using actual data for electrical energy and fuel consumption. The derived models have demonstrated the existence of strong relationships between energy consumption and management control factors; for instance, the values of R2 range from 60% to 90%. This implies that an equivalent percentage of the variations in energy consumption can be attributed to the selected management factors. The economic model developed in this research is concerned with demonstrating that effective management practices associated with proper maintenance and housekeeping can result in highly significant savings in energy usage. Although a simplistic methodology was used to evaluate the economic impact of any improvement programme, the economic treatment showed that the cost of improvement is actually negligible compared to the realisable savings in energy usage. The research has dealt with the details of developing a coherent energy management model whose objective is to establish transformational management processes of certain high-level management factors into daily operations and controls. The high-level management .factors are the same factors used as independent variables in the statistical and economic models, which statistically proved to be the major factors affecting the energy consumption at JCF. The research has also presented a detailed analysis of the organisational and procedural aspects of energy management with concentration on management functions, especially planning, controlling, executing, organising, and auditing. A detailed mapping and analysis of these functions as the main components of an Energy Management System (EMS) resulted in establishing job descriptions, organisational charts, work instructions and procedures for all-important functions of the EMS. The type of work described in this thesis could be extrapolated for application in other industries, particularly energy-intensive ones, to arrive at the objective of rational use of energy at the national and international levels. Comprehensive studies would need to be carried out for each type of industry prior to implementation. The cost benefit analysis presented in this research proved, beyond any doubt, the importance of implementing the EMS in JCF. As a result of this implementation it is demonstrated that huge annual savings were realised. Finally, as a result of improving energy control factors, introducing energy conservation measures and employing management techniques at JCF to guarantee the effectiveness of all such activities, resulted in an annual savings amount to about USS 3.5 million. Therefore, if the same or similar actions are undertaken by all cement, or other highly energy intensive industries then the savings could reach billions of dollars.

Full textAbstract:
Many households in developing countries rely on biomass (wood, charcoal, agricultural wastes, sawdust, and animal dung) and coal to meet their energy needs. The burning of these fuels in open fires creates environmental problems one of which is indoor air pollution (IAP). For effective reduction of indoor air pollution in sub-Saharan Africa, it is therefore, important to understand factors that determine the choice and uptake of cleaner fuels for household energy use. This research investigates the salient factors influencing households in developing countries in choosing fuel types, using the households in peri-urban areas of Ado Ekiti, Ekiti State, Nigeria as a case study. This research used holistic approaches to understand energy issues in the study area and used methods such as questionnaires, interviews, and field observation during data collection. Key findings suggest that underlying socio-cultural contexts of households’ ethnic groups guided wood-fuel harvesting in the peri-urban areas of Ado Ekiti, Ekiti State, Nigeria. Wood fuel continues to be households’ main domestic energy source irrespective of their socio-economic status. The open burning of wood fuel causes indoor air pollution as the recorded 24-hour particulate matter levels was between 42µg/m3 – 275µg/m3 for indoor kitchens and 48µg/m3 – 648µg/m3 for outdoor kitchens. The cultural perception of the households that natural aeration blows particulates into buildings hinders them from believing that the open of burning of biomass fuels for domestic activities is the cause of indoor air pollution. Based on the findings of this study, it is argued that the traditional norms and values of the householders, being embedded in their socio-cultural contexts, are vital for understanding energy issues in the global South.

Full textAbstract:
The substantial pollution threat to the South African environment from acid mine drainage (AMD) effluents has been well documented. Due to the juvenile nature of acidity in these flows, any remediation strategies implemented will need to function effectively and at low cost for long periods of time. The widespread use of sulphate reducing biological systems for the treatment of such effluents, and in particular large volume flows, has been limited. The supply of inexpensive electron donor and carbon sources, as well as appropriate reactor designs capable of handling large volume flows, have been identified as among the principal factors limiting development of this technology. The broad aim of the research programme reported here was to undertake an evaluation of the feasibility of an algal-bacterial integrated ponding system for the treatment of AMD, and the waste stabilisation pond (WSP) as an appropriate reactor design for this application. The study attempted to demonstrate the feasibility of individual unit operations in a proposed process train using complex organic carbon serving as the electron donor source for the sulphate reducing bacteria (SRB). Studies were undertaken as laboratory and pilot-scale investigations. Tannery effluent was shown to be a functional carbon source for biological sulphate reduction, with effective removal of sulphate and organics being recorded. In turn, the use of biological sulphate reduction for the treatment of tannery effluent was demonstrated. Algal biomass was shown in laboratory studies to function as an effective carbon source for biological sulphate reduction. It is known that micro-algae produce large quantities of photosynthate which is released to the growth medium under conditions of physiological stress. The potential for the use of photosynthate production in high rate algal ponding systems and its manipulation and use as a sustainable carbon source for sulphate reduction was investigated. Growth of a mixed culture of Dunaliella under conditions of light, temperature and salinity stress demonstrated production of large quantities of organic carbon. However, growth was inhibited at high temperatures. An elevation of salinity levels led to a decrease in growth of Dunaliella, but to increased organic carbon production. Spirulina spp., on the other hand, grew well at higher temperatures but showed the highest organic carbon production, and release to the medium, under low light conditions. These results led to a proposed process for the integration of algal ponding into an integrated system for the treatment of AMD. The algal biomass may be fed into the anaerobic digester as a carbon source, or it may be passed into a High Rate Algal Pond (HRAP) where it is stressed to enhance the organic carbon content. This can then be fed into the anaerobic digester as a carbon source. The impact of high levels of sulphide in the water feeding to the algal growth compartment was investigated. Spirulina spp. isolated from a tannery waste stabilisation pond was shown to be a sulphidophilic strain of cyanobacterium, capable of being adapted to high concentrations of sulphide. Dunaliella salina on the other hand was less tolerant. These results demonstrated the practical use of algal biomass providing an oxygen-rich cap for odour control on the surface of the facultative pond as well for the secondary treatment of sulphide-rich overflow to the High Rate Algal Pond. The ability of micro-algae to elevate the pH of their surrounding environment was evaluated as a functional precipitant and neutralisation reagent for acidic metal containing wastewater. Spirulina spp. was shown to perform effectively. D. salina was less functional in this environment. Anacystis spp. was effective in elevating the pH of a defined medium as well as a zinc-rich effluent. These results indicated the practicality of a neutralising function for algal ponds in the treatment of AMD. Metal removal in the system was found to be a combined function of sulphide precipitation, removal by binding to micro-algal biomass and extracellular polymeric substances. The feasibility of waste stabilisation ponding technology use for the treatment of large volume AMD effluents was provisionally demonstrated. It was shown that complex carbon sources would be used as efficient electron donors for sulphate reduction. The integration of algal ponding into the system provides for the generation of a sustainable carbon source, odour control with the recycling of oxygen-rich water onto the top of the facultative pond, secondary treatment of the anaerobic digester overflow, and the neutralisation of the incoming acidic effluents and removal of heavy metals. Integration of the individual unit operations, the feasibility of which has been provisionally demonstrated in this study, into a continuous process train is being investigated in follow-upstudies.

Full textAbstract:
This study develops and tests a methodology that can be utilized for a reconnaissance level assessment of electric power supply alternatives for medium-scale mining in northwestern British Columbia.
The study is organized into four parts.
Part one characterizes the public planning framework of the study area. Present and future use trends of the region's natural resources, in particular minerals and energy, are reviewed, and a typology of public preferences for their development is established.
Part two carries out a literature-based review of the conceptual basis of normative decision-making. Specific energy project evaluation approaches are introduced. This establishes a theoretical framework for constructing the methodology.
Part three presents the energy project assessment methodology.
Part four applies the methodology to the RED-CHRIS deposit.
Salient features of parts three and four which form the core of the study, are outlined below.
Energy Project Assessment Methodology
The central part of the study proposes a strategic, reconnaissance-level methodology for evaluating energy supply alternatives for medium-scale mining. Its scope is defined by; a) inclusion of strategic elements such as emphasis on priorities, analytical continuity, robustness, and adaptiveness, and b) adoption of a reconnaissance approach which reflects
an intention to accommodate preliminary information at an appropriate level of complexity and comprehensiveness.
The essence of the methodology entails three inter-related components:
1) Core Information Environment - Identifies and focuses on defining the energy supply issues for a particular undeveloped mineral deposit.
2) Basic Evaluation Environment - Assesses the viability of potential alternatives through the application of multiple criteria and formal decision-making procedures.
3) Peripheral Evaluation Environment - Assesses strategic information which is independent of the focused problem, but can exert an influence on the outcome of both the core and basic environments.
Each component contains strategic data bases and analytical processes that assist the analyst to proceed from initial problem identification to selection of alternatives. Within and between the three structural component information is refined in an iterative fashion. This maintains a current perspective on the problem environment and leads to a more confident appraisal of the favoured energy alternatives for a mineral deposit.
Case Study Analysis:
RED-CHRIS copper-gold deposit situated southeast of Iskut was selected for a case study application of the methodology. Typical production schedule ranging from 8 to 20 years would require corresponding installed electrical capacity of 7.5 to 23.5 Megawatts.
Key points which emerged from an analysis of this deposit's energy supply alternatives form the mine planner's perspective are:
1) Interest groups concerned with planning, developing, or regulating energy supply for RED-CHRIS include:
a) Mineral deposit owners whose objective it is to maximize profit b) Societal interests whose objective it is to maximize economic, social and environmental well-being aspects of the project.
c) Public policy interests whose objective it is to maximize economic, political, and social welfare within national and provincial energy policy.
2) Energy supply candidates identified and examined, include: diesel-electric, high voltage grid extension, small-hydroelectric, coal and biomass-fired generation, natural gas, peat, geothermal, wind and solar.
3) Comparison of different small-scale energy applications for remote areas is made difficult because of technical, political, and environmental uncertainties.
4) Satisficing and Dominance can be successfully applied from the mine planner's perspective to key decision criteria to narrow the various energy supply alternatives.
5) Small-hydro is the most favourable alternative at this juncture, followed by diesel. Coal-fired generation and biomass are comparable, and may be more favourable than diesel under certain circumstances. Other alternatives are presently unsuitable.
General Conclusions: Application of the methodology is limited by the interaction between analytical design, available physical resources, and uncertainty in the operating environment, human values and external decisions.
The methodology appears sufficiently robust and comprehensive to be adapted to other deposits in the region. Commonly shared information requirements combined with the iterative nature of information processing, can be used to reduce the resource demands and improve the efficiency of subsequent applications. Finally, it is recommended that the value sensitivity of the methodology be tested by applying it from more than one perspective to the same deposit.Applied Science, Faculty of

Thesis (MTech (Chemical Engineering))--Peninsula Technikon, Cape Town, 2003The monitoring of pesticide contamination in surface and groundwater is an essential aspect of an assessment of the potential environmental and health impacts of widespread pesticide use. Previous research in three Western Cape farming areas found consistent (37% to 69% of samples) pesticide contamination of rural water sources. However, despite the need, monitoring of pesticides in water is not done due to lack of analytical capacity and the cost of analysis in South Africa. The Solid Phase Microextraction (SPME) sampling method has been developed over the last decade as a replacement for solvent-based analyte extraction procedures. The method utilizes a short, thin, solid rod of fused silica coated with an absorbent polymer. The fibre is exposed to the pesticide contaminated water sample under vigorous agitation. The pesticide is absorbed into the polymer coating; the mass absorbed depends on the partition coefficient of the pesticide between the sample phase and the polymeric coating, the exposure time and factors such as agitation rate, the diffusivity of the analyte in water and the polymeric coating, and the volume and thickness of the coating. After absorption, the fibre is directly inserted into the Gas Chromatograph (GC) injection port for analysis. For extraction from a stirred solution a fibre will have a boundary region where the solution moves slowly near the fibre surface and faster further away until the analyte is practically perfectly mixed in the bulk solution by convection. The boundary region may be modelled as a layer of stationary solution surrounded by perfectly mixed solution.

Full textAbstract:
Greenhouse gases (GHGs) are vital components of the earth�s atmosphere, trapping heat around the earth, maintaining temperatures necessary for human existence. Until the Industrial Revolution, these gases existed in a natural equilibrium with the environment. Since that time, anthropogenic activities such as fossil fuel burning and land clearing have increased the quantity of GHGs, such as carbon dioxide (CO2) and methane (CH4), in the earth�s atmosphere. Evidence indicates that global warming is occurring as a result of the additional accumulation of GHGs in the atmosphere.
International response to climate change resulted in the 1997 development of the Kyoto Protocol. If the Protocol is ratified, developed countries will be legally bound to reduce their GHG emissions in accordance with negotiated emission reduction targets. At the beginning of the year 2001, the Protocol was still to be ratified.
With the possibility of future GHG emission restrictions, some Australian companies have started quantifying their GHG emission levels. One such company is Visy Industries, the largest privately owned paper packaging manufacturing company in the world. Visy�s core business is the manufacture of cardboard boxes from recycled paper. As part of its future operations, a kraft pulp and paper mill is presently being built in New South Wales, Australia.
The environmental decision support tool, Life Cycle Assessment (LCA), was used to quantify Visy�s CO2 and CH4 emissions across the entire life cycle of the Visy paper recycling and virgin papermaking processes. Commercially defined LCA models were developed for both papermaking processes.
GHG emissions estimated by each model were compared and the effect of different energy sources, technologies and manufacturing processes on CO2 and CH4 emissions were assessed. The majority of emissions in the two Visy papermaking models were due to fossil fuel derived energy sources and the decomposition of wood fibre in Solid Waste Disposal Sites (SWDSs). Results were used to propose appropriate GHG reduction strategies and business opportunities.
GHG reduction strategies included increasing the use of renewable energy, reducing the volume of solid waste rejects sent to SWDS, incinerating solid waste rejects with energy recovery and sourcing steam from third party providers. Proposed GHG business opportunities included increasing the production of Greenpower from the pulp and paper mill for sale to the grid.
This thesis is an example of the practical application of current GHG knowledge and LCA methodology that was undertaken in an environment where technical, political and commercial guidelines at both a national and international level were still evolving. Nevertheless, the thesis is not a critical review of LCA methodology.
The LCA support tool was able to quantify CO2 and CH4 emissions across the life cycle of the Visy recycling and virgin papermaking processes. The chosen functional unit, the assumptions and exemptions made, and the placement of the system boundaries, were found to be critical to the Visy LCA results.

Full textAbstract:
Extended producer responsibility (EPR) as a holistic approach to product stewardship has been increasingly incorporated into environmental policy agenda in the last two decades. One major expectation of EPR is to prevent environmental problems at source by providing appropriate incentives for product eco-design changes. However, available studies empirically examining the actual influence of EPR on eco-design are limited. This research therefore aims to fill the research gap by evaluating the effectiveness of existing EPR programmes in driving eco-design changes from the perspective of China’s electrical and electronic (EE) industry, and shed some light on the prospects of EPR development in China.
Based on the analytical framework developed from reconstructed intervention theory, three intensive empirical studies have been carried out. The first study examines the perception and responses of 50 China’s EE manufacturers regarding the EU EPR programmes (i.e. the WEEE and RoHS Directives). The second study investigates the responses of 36 China’s EE manufacturers to the Chinese EPR programmes (i.e. China WEEE and China RoHS legislation) and identifies possible factors that exert causal impact on the occurrence of eco-design. In order to gain a deeper insight into the practical manifestations of effective EPR implementation in the private sector, three company case studies have been conducted in the third stage of the research, serving as an important supplement to the first two studies.
The three studies show that EPR programmes in a stringent regulatory approach focusing on products’ environmental properties such as substance bans can exert strong influence on design changes. However, mandated recycling legislation seems to have little driving effect for companies to change product design. The research points to the weakness of collective producer responsibility that is currently adopted in many EU Member States for WEEE implementation in achieving continuous eco-design improvements. It highlights the significance of realising the principle of individual producer responsibility in EPR programmes for achieving this goal.
Based on an attributability assessment, the research further shows that there are a number of factors that influence the adoption of eco-design in China, and the link between legislative EPR programmes and eco-design is complex and evolving. Not only may the EPR programmes have different existing, anticipating and potential effect on the incorporation of eco-design, but they may have very different driving influence on environmental laggards and leaders.
In this regard, this research suggests that there is no one-stop solution for EPR in China. A mixed mechanism that integrates various policy instruments such as administrative, economic and informative instruments, in conjunction with cooperation and infrastructure facilities, would be the most effective means to implement EPR in the context of China, thereby achieving the goal of sustainable production and consumption.published_or_final_version

Full textAbstract:
Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2018.The oil industry has been a major contributor to economic development in many countries; providing jobs, revenue, infrastructure and businesses to third parties. However, this development has also come with adversity on the physical environment. The oil industry accounts for the highest Green House Gas (GHG) emissions in the world, making it the number one polluter. In addition, South Africa has been regarded as the biggest polluter in Africa, with fossil-based fuel cited as the major cause of environmental degradation. South Africa’s physical environment is also cited as having degraded more than most countries in Africa. This proposition requires players in the oil industry to urgently address this situation. As the future of economic development is likely to be spearheaded by the oil industry, concerns have been raised at the slow rate of addressing oil companies’ operations which causes the environment to be less sustainable. This study uses a qualitative content analysis to explore the oil companies’ actions towards addressing environmental adversity caused by their unsustainable operations. In order to be environmental sustainable, oil companies must; incorporate environmental sustainability into missions and visions, financial investment into sustainable initiatives, involve top management in environmental programs, engage stakeholder, comply and align organisational processes and operations with environmental legislations and introducing renewable energy.

Full textAbstract:
Urbanization, often characterized by high impervious surface area, can result in excessive inputs of fine sediments into urban streams. Excessive fine sediments can blanket the stream bed filling the interstitial space in the substratum, which may have adverse effects on stream biota. A field survey was conducted in Oregon urban and non-urban basins to investigate the relationship between fine sediments and stream macroinvertebrates. Physical, chemical, and biological data were collected from 59 stream sites in two urban and two rural streams. The stream sites fulfilled a continuous sediment gradient, which ranged from a low of 2% of fine sediment in the substrate to a high of 64% with an average of 22%. The % fines, in Clear Creek (rural basin) was significantly lower than in the urban basins (Johnson Creek and Tryon Creek) (p=0.005). Johnson Creek (mean=23%) had approximately three times more fine sediment than Clear Creek (mean=7%), while Tryon Creek (mean=32%) had nearly five times as much fine sediment as Clear Creek. EPT taxa richness was significantly higher in both rural streams than in both urban streams (p0.05). For example, regression analysis of EPT taxa richness vs. % fine sediments displayed a coefficient of determination (r2) value of 0.2. Other macro invertebrates metrics displayed similar patterns. The lack of significant correlations may be due to the cumulative effect of basin-wide "historical land use past". Past land use activity may have resulted in long-term reductions of sensitive taxa in the basin taxa pool and efforts to improve local habitats may not be quickly colonized by pollution sensitive taxa. Long-term degradation to the urban streams resulted in a relatively homogenous assemblage of macro invertebrates, which may have confounded the quantitative relationship between sediments and macroinvertebrates. This study suggests there is a clear difference between urban and non-urban streams in terms of macro invertebrates, which may be likely due to sediments, but the quantitative relationship between fine sediments and macro invertebrates is weak.

Fundação Araucária; CAPESAs indústrias alimentícias utilizam considerável volume de água para suprir a demanda de processos. Devido a isso, observa-se um grande volume gerado de efluentes que necessitam ser tratados para garantir o destino final adequado. Tendo em vista a crescente escassez de água, procedimentos de racionalização do uso da água e o reúso de efluentes tratados surgem como soluções para estes problemas. A aplicação de processos de separação por membranas no tratamento de efluentes da indústria alimentícia para reúso apresenta-se como um processo de tratamento avançado apropriado. Deste modo, o objetivo deste estudo foi avaliar a utilização dos processos de separação por membranas como tratamento avançado de águas residuárias agroindustriais provindas de um abatedouro e frigorífico de suínos, da região oeste do Paraná, visando à possibilidade de reúso destes efluentes. Para isso, foi necessário: realizar a caracterização físico-química dos efluentes agroindustriais; avaliar o emprego de microfiltração, ultrafiltração, e microfiltração seguida de ultrafiltração em diferentes condições operacionais de pressão aplicada à membrana, e avaliar a qualidade do efluente obtido pelos processos de separação com membranas, considerando o atendimento das exigências técnicas, legais e sanitárias para diferentes usos industriais. Os resultados mostraram que os processos de separação por membranas apresentaram, de uma maneira geral, uma sensível melhora na qualidade do efluente final quando comparados com o atual sistema de pós-tratamento empregado pela indústria (flotador físico-químico), que promove eficiências de remoção nas faixas oscilantes de 3% a 29%, 44% a 70%, 40% a 46% e 50% a 58,5%, aproximadamente, para os parâmetros sólidos totais voláteis, turbidez, nitrogênio amoniacal e DQO, respectivamente. A microfiltração apresentou as seguintes faixas de eficiência de remoção, aproximadas: sólidos totais voláteis (51% - 64%), turbidez (83% - 99%), nitrogênio amoniacal (21% - 24%) e DQO (64% - 72%). A ultrafiltração apresentou as seguintes faixas de eficiência de remoção, aproximadas: sólidos totais voláteis (23% - 51%), turbidez (87% - 99%), nitrogênio amoniacal (54% - 69%) e DQO (77% - 85%). A realização do ensaio de microfiltração seguido de ultrafiltração nas melhores condições experimentais investigadas obteve resultados satisfatórios na remoção de aproximadamente 97% para a turbidez, 17% para os sólidos totais voláteis, 67% para a DQO, 38% para o nitrogênio amoniacal, 96% a 99,95% para os coliformes termotolerantes e 93 a 99,69% para os coliformes termorresistentes. Com o aumento da pressão para a microfiltração e ultrafiltração foi obtido maior fluxo permeado e melhor qualidade do efluente final. Embora os efluentes tenham proporcionado distintos valores de fluxo permeado, foram obtidas curvas de desempenho bastante semelhantes, caracterizando-se por uma queda do fluxo permeado nos primeiros minutos de filtração, seguido de um período onde ocorre declínio gradual, com uma tendência ao equilíbrio. De acordo com os requisitos físico-químicos e microbiológicos mínimos exigidos para o reúso de efluentes tratados, a microfiltração e a ultrafiltração atenderam alguns dos parâmetros monitorados, alcançando a qualidade exigida para o reúso em torres de resfriamento, lavagem de pisos, irrigação de áreas verdes, lavagem de veículos, proteção contra incêndio e descarga sanitária.
The food industry uses large volumes of water to meet the demand processes. Because of this, there is a large volume of generated waste that need to be addressed to ensure proper final destination. In view of the growing scarcity of water, the use rationalization of procedures of the water and the reuse of treated effluent arise as solutions to these problems. Application of separation processes by membranes in the treatment of wastewater for reuse food industry presents itself as an appropriate advanced treatment process. Thus, the aim of this study was to evaluate the use of membrane separation processes as advanced treatment of agroindustrial wastewater stemmed from a swine slaughterhouse, the western region of Paraná, aiming at the possibility of recycling these effluents. For this it was necessary: to define the physical-chemical characterization of the agro-industrial effluents; evaluate the use of microfiltration, ultrafiltration, microfiltration and ultrafiltration then under different conditions of pressure applied to the membrane, and evaluate the quality of the effluent obtained by separation processes with membranes, considering the care of the technical, legal and health requirements for different uses industrial. The results showed that membrane separation processes presented in a general way a considerable improvement in final effluent quality compared with the current tertiary treatment system used by the industry (physicochemical flotation) which promotes removal efficiencies in oscillating ranges from 3% to 29%, 44% to 70%, 40% to 46%, 50% to 58.5%, approximately, for the parameters: total volatile solids, turbidity, ammonia nitrogen and COD, respectively. Microfiltration had the following removal efficiency ranges, approximate: total volatile solids (51% - 64%), turbidity (83% - 99%), ammonia nitrogen (21% - 24%) and COD (64% - 72%). Ultrafiltration showed the following removal efficiency ranges, approximate: total volatile solids (23% - 51%), turbidity (87% - 99%), ammonia nitrogen (54% - 69%) and COD (77% - 85%). The completion of the test microfiltration followed by ultrafiltration under the best experimental conditions investigated achieved satisfactory results in the removal of approximately 97% for the turbidity, 17% total volatile solids, 67% for COD, 38% for ammonia nitrogen, 96% to 99.95% for thermotolerant and 93 to 99.69% for the heat-resistant coliforms coliforms. With increasing pressure to microfiltration and ultrafiltration permeate flux was increased and better quality of the final effluent. Although the effluents have provided separate permeate flow rates, very similar performance curves were obtained, characterized by a drop in permeate flux during the first minute filtration followed by a period where there is a gradual decline, with a tendency toward equilibrium. According to the physicochemical requirements and minimum microbiological required for the reuse of treated wastewater, microfiltration and ultrafiltration attended some of the monitored parameters, achieving the required quality for reuse in cooling towers, floor washing, irrigation of green areas , washing vehicles, fire protection and sanitary discharge.

Thesis (MBA)--Stellenbosch University, 2014.ENGLISH ABSTRACT: The research found and understood that the ability of the case study organisation (company X) to understand sustainability issues and stakeholder interests lies in the firm‟s core purpose and strategy (i.e. the notion of incorporating sustainability into business decisions). The research also understood that at company X the three strategy propositions (value, profit, people) are achieved through the process of implementing the company‟s change initiatives for sustainability and in turn support the company to evolve towards a sustainable enterprise. The ability to make sustainability a fundamental aspect of its business decisions is what distinguishes company X such that it can successfully design, introduce and diffuse strategies, practices and cultural traits aligned with sustainable models The researcher further believes that change interventions or initiatives carried out at company X such as value delivery, workforce plan alignment and cash generation are expected to enhance responsibility and accountability of employees. At company X, individuals are informed and allowed a great deal of autonomy when it comes to generating ideas to tackle strategic initiatives. The sense of inclusiveness allows individuals in company X to change their identity and behaviour in line with ideal models of the sustainable enterprise.

Full textAbstract:
Natural soils in the Appalachian coal mining region occur on steep slopes and are often thin, rocky, acidic, and/or infertile. This often makes use of natural topsoil for surface coal mine reclamation impractical. Sandstone (SS) and siltstone (SiS) topsoil substitute materials in mixed and pure treatments were compared to ascertain their effects on soil genesis and tall fescue (Festuca arundinaceae Schrab.) growth in a rock mix study. A second surface amendment experiment with similar objectives was established and contained treatments of sawdust, topsoil, a control, and four rates of sewage sludge.
Soil pH, extractable P, and coarse fragment contents decreased at the soil surface from 1982 to 1984. The CEC decreased from 1982 to 1983 due to leaching of cations solubilized from carbonates, but stabilized by 1984. Soil total-N and water availability increased from 1982 to 1984.
Particle size distributions changed as sand and >2 mm sized materials weathered into silt and clay sized particles. As sand contents decreased over time, silt contents increased. Morphologically distinct A horizons developed in these soils rapidly and were formed primarily by plant rooting and organic matter additions. Treatment application, topsoil substitute placement, and grading also created morphologically distinct horizons.
Fescue biomass production indicates topsoil substitutes support more vigorous vegetative growth than topsoil, especially when topsoils are mixtures of subsoil and A horizons. Biomass production was primarily limited by N, P, and water availability. Blended rock mixes consistently supported higher biomass production than pure SS and SiS treatments. Municipal sewage sludge applied at rates-56 Mg/ha equaled or exceeded inorganic fertilization for establishment and maintenance of tall fescue stands, and did not cause heavy metal phytotoxicity.M.S.

Full textAbstract:
This study is aimed at developing policies for energy efficiency by observing the past changes of energy use in Indonesia???s manufacturing sector over the period 1980???2000, and to investigate mitigation options for energy-related CO2 emissions in the sector. The first part of the study uses decomposition analysis to assess the effect of the changes in energy consumption and the level of CO2 emissions, while the second part investigates energy efficiency improvement strategies and the use of economic instruments to mitigate CO2 emissions in the manufacturing sector. Economic activity was the dominant factor in increasing energy consumption over the whole period of analysis, followed by the energy intensity effect and then the structural effect. The increase in aggregate energy intensity over the period 1980-2000 was mainly driven by the energy intensity effect. In turn, the technical effect was the dominant contributor to changes in energy intensity effect, with the fuel-mix effect being of lesser importance. Changes in CO2 emissions were dominated by economic activity and structural change. Sub-sectors that would benefit from fuel switching and energy efficiency improvements are the textile, paper, and non-metal sub-sectors. Three main options for reducing CO2 emissions from the manufacturing sector were considered: the imposition of a carbon tax, energy efficiency initiatives, and other mitigation measures. A carbon tax was found to reduce sectoral emissions from the direct use of oil, gas and coal, but increased the demand for electricity. At the practical level, energy efficiency improvements can be implemented by adopting energy efficient technologies that can reduce aggregate energy intensity up to 37.1 per cent from the base-year level, estimated after imposition of a carbon tax at $30 per tonne of carbon. A major priority for energy efficiency improvements was found to be in the textile and the paper and chemical sub-sectors. A mitigation measure such as the Clean Development Mechanisms could be encouraged in order to reduce projected emission levels. The preferred option would be the adoption of energy efficient technologies in the textile, chemical, paper and non-metal sub-sectors.

Detailed snow surveys were carried out in the Allt a Mharcaidh catchment on the western edge of the Cairngorm mountains during the winters of 1985/86,1986/87 and 1988/89. Snowpack data collected included depth, density, areal extent and water equivalent. From these data it was possible to determine seasonal patterns in snowpack behaviour and relate these to the initial snowpack water equivalent volume and timing of the snow accumulation and ablation. Using meteorological and flow data collected in the Mharcaidh by the Institute of Hydrology as part of the SWAP project simple linear regression relationships were determined. These indicated that the availability of detailed meteorological data did not improve the ability to simulate observed flow and that a successful regression could be established using simple and readily available data. Using this data temperature index models were developed and tested on the Mharcaidh. These showed that the mean daily temperature provided a better index of melt than more complex indices and that simple changes regarding the addition of a freezing level hindered the model performance despite being closer to reality than other assumptions made in the model. This suggested that the degree of complexity in the model has to be similar for all operations to obtain optimum results; having one particularly complex sub-model reduces the performance of the others. Two other types were tested on the Mharcaidh based on the layered structure developed by Martinec (1975) and Anderson's (1968) method using temperature and windspeed as an index to the energy changes at the snowpack boundary during rain-on--snow events. These again show that simple methods using readily available data can produce acceptable results and that increasing the complexity of the model does not produce a similar increase in performance. The three different models were then run on different datasets for different catchments and years. The dependence of Anderson's method on good quality data is highlighted suggesting that it is not as widely applicable as the other models. The level of performance for all models is related to the extent and depth of the snowpack indicating that further improvements may be necessary to the hydrological components of the model rather than the melt sub-model itself. The models were tested in simulated real time conditions on one dataset and, following this, guidelines for use in real time to predict snowmelt runoff are given.

Full textAbstract:
Increased use of renewable energy sources in the generation of electricity isa crucial component of transitioning to a less polluting energy system in the United States. Technologies like solar photovoltaic cells and wind turbines are being deployed at a rapid rate around the country, which means that an increasing portion of the public is becoming aware of renewable energy systems. The construction of these new industrial facilities has resulted in a variety of public reactions, positive and negative. Citizen opposition has been widely observed toward a variety of renewable energy facilities, and citizen groups can influence policy-making at the national, state,and local levels. Further research is needed to understand under what circumstances the public may take oppositional stances.
To examine this topic, I analyze public perceptions of renewable energy using three different datasets. First, I used data from a survey conducted in 2014 in five communities in Utah, Wyoming, and Idaho experiencing renewable energy development(n=906). This dataset allowed me to untangle what factors help explain both individual as well as community-level variation in support for renewable energy. Second, I employed nationally representative survey data (n=13, 322)collected from 2008 to 2015 to examine the influence of a number of factors hypothesized to shape individuals’ level of support for renewable energy policies including socio-demographic characteristics, political beliefs, belief in anthropogenic climate change, and nearby extractive industry activities. Last, I analyzed discourse about renewable energy in sixty-one semi-structured interviews with individuals representing various community sectors in three energy-producing rural communities in Utah.
My research findings, on a whole, suggest that several place-based factors are significant in shaping public opinion about renewable energy, including community experience with renewable energy and local economic reliance on extractive industries. I also find pervasive climate skepticism across study sites. These findings indicate the need for broad-based and non-partisan discursive frames for renewable energy. Last, these findings speak to the importance of the ‘just transitions’ concepts, and the need to incorporate those communities most marginalized by the current system of fossil fuels extraction and production as society moves forward toward a cleaner energy economy.

Thesis (MTech (Public Relations Management))--Cape Peninsula University of Technology, 2016.The history of public relations include facets of “publicity” and “press agentry,” and has matured beyond these narrow, tactical functions, rising to accept positioning as strategic communications which can drive corporate social responsibility decision-making that resonate credibly with community stakeholder. The study explored public relations models of communication within stakeholder engagement to establish corporate social responsibility projects in the mining sector in Richards Bay, South Africa. The stakeholder engagement process depends greatly on principles outlined in the King Reports, which includes a stakeholder ‘inclusive approach’ and ethical guidelines for ‘governing stakeholder relationships’ and emphasises ‘sustainable development’. Furthermore, a socially responsibility business integrates the economic, legal, ethical and discretionary obligation of business to society and further recognizes its place in the broader community. Although qualitative research design was chosen for this study, the research used purposive sampling to select individuals and groups for data collection on the stakeholder communication experience. Six Individual in-depth interviews and one focus group interview were conducted with the organisation’s Communities and Corporate Relations team and the community leaders. The research reports that the corporate social responsibility stakeholder engagement process has five stages (consultation, engagement, agreement, decision making and feedback) and there is an evaluation process on community development projects set by the organisation. Consequently, the organisation and the communities both benefit from the corporate social responsibility projects. Additionally, the analysis shows that the model used for stakeholder engagement within corporate social responsibility is the mixed-motive model of public relations. Hence, the relationship between the organisation and its host communities is established and maintained, as well as the social licence to operate and reputation is enhanced. Therefore the research concludes that a public relations’ mixed-motive model of communication is best suited for stakeholder engagement in order to establish corporate social responsibility projects in the host communities that can enhance favourable organisation-community relationships. The model intends to achieve equilibrium between the organisation and the community stakeholder. However, further research is recommended into the development of a new African public relations model of communication that encompasses the concept of ‘Ubuntu’ where the community leader is the final decision maker in consultation with the traditional council.

Full textAbstract:
One of the greatest challenges facing the world today is integrating industrial activities such as mining with environmental integrity and social concerns. Monitoring is fundamental to environmental management, both to assess the adherence to standards and to allow environmental managers to learn from practical experiences. However, a problem arises when the regulatory authorities cannot keep up with their mandate of enforcement and compliance monitoring. This research examined how the Department of Minerals and Energy (DME) implements the concept of sustainable development in the mining sector of the Eastern Cape (EC) and, more specifically, the extent to which the Mine Environmental Management (MEM) section is able to effectively monitor compliance of mining operations with environmental legislation. This was the first systematic compilation of statistical data for the DME, and presents the first study in the EC regional office in terms of environmental sustainability. Results indicate that there has been a sustained increase in mining activity over the past three years, possibly as a result of the boom in the construction industry and the accelerated road maintenance and improvement programmes in the Eastern Cape. Mining applications received by the DME have increased by 47% from 2006 to 2007 (January-May) and by a further 100% from 2007 to 2008. In addition to the increasing number of mining concerns being established, 98 mining concerns will need to apply for the conversion of their old order rights to new order rights by the 1st May 2009. Mining in the province is predominantly small scale with mining permits (mined areas less than 1.5Ha) making up 52.3% of all applications, with larger mining concerns contributing 29.3% and prospecting contributing the remaining 18.4%. In terms of compliance inspections, the EC regional office is required to conduct 120 environmental compliance inspections annually in terms of contributing to sustainable development. The MEM section exceeded this target since 2003. However, when the number of operational mines is considered, 120 inspections per year equates to one mine being visited, on average once every four years (based on 2008 data). Based on projected figures (number of compliance audits and number of operational mines) for 2009, the DME’s target of 150 inspections for 2009/10 combined with the limited staff D. Watkins – MBA Dissertation 2008 capacity will, at best, mean that mines would be inspected once in seven years. However, the target of 150 inspections will not actually even cover the expected number of EMP evaluation inspections. This has serious implications in terms of regulating the compliance of the mining concerns with their EMPR’s. The low level of compliance monitoring can be directly related to staff capacity and logistics problems at the regional office as well as provincial targets being based on staff capacity rather than the number of operational mines. Thus, considering potential environmental damage associated with mining operations and the capacity constraints of the MEM to conduct frequent compliance audits, it is likely that mining operations will have negative implications for sustainable development in the region. Currently there are many challenges facing the DME in terms of contributing positively to sustainability in the mining sector and there is a need to base future actions on the idea of continuous improvement and ultimately progress.

Full textAbstract:
Australia is experiencing widespread ecosystem degradation, including dryland salinity, erosion and vegetation loss. Approximately 1 million hectares (5.5%) of the south-west agricultural zone of Western Australia is affected by dryland salinity and is predicted to rise to 5.4 million hectares by 2050. Such degradation is associated with many environmental outcomes that may impact on human health, including a decrease in primary productivity, an increase in the number of invasive species, a decrease in the number of large trees, overall decrease in biodiversity, and an increase in dust production. The resulting degradation affects not only farm production but also farm values. This study examines the effects of such severe and widespread environmental degradation on the physical and mental health of residents. Western Australia has an extensive medical record database which links individual health records for all hospital admissions, cancer cases, births and deaths. For the 15 diseases examined in this project, the study area of the south west of Western Australia (excluding the capital city of Perth) contained 1,570,985 morbidity records and 27,627 mortality records for the 15 diseases examined in a population of approximately 460,000. Environmental data were obtained from the Western Australian Department of Agriculture?s soil and landscape mapping database. A spatial Bayesian framework was used to examine associations between these disease and environmental variables. The Bayesian model detected the confounding variables of socio-economic status and proportion of the population identified as Aboriginal or Torres Strait Islander. With the inclusion of these confounders in the model, associations were found between environmental degradation (including dryland salinity) and several diseases with known environmentally-mediated triggers, including asthma, ischaemic heart disease, suicide and depression. However, once records of individuals who had been diagnosed with coexistent depression were removed from the analysis, the effect of dryland salinity was no longer statistically detectable for asthma, ischaemic heart disease or suicide, although the effects of socio-economic status and size of the Aboriginal population remained. The spatial component of this study showed an association between land degradation and human health. These results indicated that such processes are driving the degree of psychological ill-health in these populations, although it remains uncertain whether this 4 is secondary to overall coexisting rural poverty or some other environmental mechanism. To further investigate this complex issue an instrument designed to measure mental health problems in rural communities was developed. Components of the survey included possible triggers for mental health, including environmental factors. The interview was administered in a pilot study through a telephone survey of a small number of farmers in South-Western Australia. Using logistic regression a significant association between the mental health of male farmers and dryland salinity was detected. However, the sample size of the survey was too small to detect any statistically significant associations between dryland salinity and the mental health of women. The results of this study indicate that dryland salinity, as with other examples of ecosystem degradation, is associated with an increased burden of human disease.
