Résumé :
There is a consensus globally that climate change is one of the biggest challenges facing operations. Immediate actions are required to reduce the carbon footprint in order for the environment to endure future logistics processes and activities (The National Treasury department of South Africa, 2010). Greenhouse gases (GHGs) are emissions generated from manufacturing processes, distribution networks and treatments processes (Verfaillie and Bidwell, 2000). Companies globally are expected to monitor pollution and focus on reducing the discharge of pollutants. Logistics Managers are therefore pressured to reduce the carbon footprint as it affects the environment and our health. Companies are becoming more concerned with the impact of various activities and processes on the environment. Traditional logistics models, primarily focuses on minimising cost with little focus on the environmental impact and sustaining operations for the future (Sbihi and Eglese, 2009) General Motors (GM) is a multi-national vehicle manufacturer with operations in various countries. GM filed for bankruptcy in 2009 resulting in the formation of the new GM; one of the focus areas was to ensure sustainability which resulted in the introduction of the ‘Sustainability in motion’ program in 2009 (New York Times, 2009). General Motors South Africa (GMSAf) is a vehicle assembler with manufacturing facilities and head offices located in Port Elizabeth. The company is a wholly owned subsidiary of the multinational General Motors Company. The aim of the research is to determine whether a culture that promotes environmentally conscious behaviour exists within employees and their relationships within a team, with management, stakeholders and suppliers. The study will assist in highlighting areas which need improvement to enable the creation of environmentally sustainable initiatives and implementation thereof. The empirical study revealed that the following management commitment, education and training, performance management and participation and involvement were important factors in the effective implementation of an environmental sustainability program.

Résumé :
The current trends in sustainable development (SO) were examined in this study, which brought about the realisation that SO has become a business imperative. Mining, which is a highly impacting industry, is faced with the dilemma of implementing the principles of SO despite the realisation that its activities are severely limited by· the finite nature of the resource it is capitalising on. This reality, however, does not detract from the non-negotiable requirement for the industry to meet the increasing pressures to act responsibly towards the environment and the community in which it operates. Gold Fields has stepped up to the plate and has already taken several steps to achieve this end. These include the adoption of SO in its Vision, Values and strategies and the development and implementation of a SO framework to ensure the integration of the principles of SO into the business. Furthermore, Gold Fields has also entered into voluntary activities that further cement the commitment the company has towards so. These other initiatives include, inter alia, its International Council on Mining and Metals membership, UN Global Compact participation, becoming a signatory to the cyanide code, IS014001, and so on. This study focussed on several indicator categories and the identification of a set of supporting sustainable development indicators (SOls) for each, which included environmental, social, economic, technological, and ethics, legal and corporate governance (not in order of priority). These indicators were assessed by a carefully selected group of respondents whose collective wisdom and expertise were used to identify and weight supporting SOls for each of the indicator categories. These supporting SOls were in turn used to develop a model that is able to assist in the business's decision making processes when capital investment is being considered . A water treatment project that is currently being considered by Gold Fields was utilised to demonstrate how the decision making model can be applied to two different scenarios. The result clearly and successfully demonstrated that by proactively taking environmental, economic, social, technological, and ethics, legal and corporate governance considerations into account, a gold mining company is able to increase the level of SO of a capital investment project.

Résumé :
This thesis examined the impact of anthropogenic alterations in four riverine catchments of the Eastern Mt. Lofty Ranges, South Australia, to identify if creek restoration via environmental flows is a viable management option and if so, to determine; 1) Whether an aquatic/riparian viable seed bank was present and if so what was its composition 2) The ecological condition of selected riverine reaches. This in combination with the seed bank study would identify those creeks that would most benefit from the imposition of environmental flows 3) The response of key species to the water regimes likely to result from the imposition of environmental flows 4) The influence of nutrient enrichment under a fluctuating water level and to use this information to formulate best practice policy for environmental flows 5) Whether aquatic plants promoted by environmental flows were a significant fraction of the diet for higher trophic levels represented by Trichopterans and Amphipods. The seed banks were of comparable density (ranging from 4,000 to 110,000 seeds m-2) and species richness (ranging from 13 to 20 aquatic / riparian species) to the seed banks of other Australian rivers and wetlands, but this varied significantly among riverine sections and across catchments. Out of a total of 81 species recorded, 51 were classified as terrestrial (63% of all species recorded). What is of greater concern was the number of exotic (both aquatic and terrestrial) species recorded: 43% of the species recorded in the Angas, 47% of the species in the Finniss, 39% of the species in Tookayerta creek and 43% of the species recorded in Currency creek were exotic, which are significantly higher in comparison to other Australian studies. There were 24 to 28 aquatic/riparian species recorded in the extant vegetation of each catchment that were not recorded in their seed banks. Likewise, a number of species (3 to 7) were recorded in each catchments seed bank that were not recorded in the extant vegetation of those catchments. A species of particular interest is Crassula sieberana, which is on the State endangered plant species list. Indices for assessing the ecological condition, health or integrity of a river or riparian habitat were employed to investigate the relationship between the river/riparian habitat and the land and water management practices associated with those habitats. Of the four catchments surveyed, each catchment identified a unique set of site parameters (subindex indicators) that were strongly correlated with its ecological condition. Indicator species analyses revealed pasture grasses to be a significant indicator of reaches in very poor condition (p = 0.0010) along the Finniss and Baumea juncea of those reaches in good condition (p = 0.0230). Along the Angas, Cotula coronopifolia was an indicator of those reaches in average condition (p = 0.0240) and along Currency creek, Cladium procerum was an indicator of those reaches in good condition (p = 0.0190). However, when all 115 surveyed reaches were analysed together, those reaches of average to excellent ecological condition were all strongly correlated (R2 = 0.50) with the subindex indicators: bank stability, % riparian cover, grazing, fenced, aquatic wood, and width of the riparian vegetation. This would indicate that these subindex indicators are the main site parameters determining the ecological condition of a riverine reach and hence its restoration potential. Those catchments or sub-catchments containing a high proportion of reaches classified to be in poor to very poor condition had significantly reduced seed banks. The influence of water level fluctuations (±15 cm, ±30 cm and ±45 cm) on the growth of four species of emergent macrophytes (Cyperus vaginatus, Phragmites australis, Typha domingensis and Triglochin procerum) were species dependent. These species naturally inhabits different zones across the elevation gradient. C. vaginatus, which has a high elevation preference, was strongly inhibited by increasing water depth and fluctuations in water levels. In contrast, species with an intermediate elevation preference, such as Phragmites australis and Typha domingensis, were more tolerant to both depth and water level fluctuations. However, the biomass and relative growth rate (RGR) of T. domingensis and P. australis were depressed when grown under the combination of deep elevation and a highly fluctuating water level (±45 cm). Between the static and ±45 cm amplitude treatments, growth of T. domingensis was inhibited by 52%. The growth of P. australis appeared to be enhanced by fluctuating water levels and only showed a severe drop-off in growth in the deep elevation, ±45 cm amplitude treatment. In C. vaginatus the RGR was dependent of the average emergent surface area (and the implied rate of carbon acquisition)(p<0.0001; r2=0.7196; F=87.276; n=36; RGR (mg g-1 day-1) = -5.096 + 4.313 × ln (Average emergent surface area (cm2)), but this was not the case in P. australis and T. domingensis (p>0.05) even when the photosynthetic canopy was partially inundated by rising water levels. Yet these two species demonstrated different growth rates when grown under different water regime amplitudes and at different elevations. Growth of T. procerum did not respond to either amplitude or elevation, but its RGR remained negative. This suggests that another factor(s) was limiting the growth of P. australis, T. domingensis and possibly T. procerum, a factor that varies with water level. Cyperus gymnocaulos had significantly increased plant performance (p <.0001) with increased nutrient loading rates but this effect was significantly reduced under a fluctuating water regime (p =0.0007). Remarkably, under a fluctuating regime, P. australis had a significant reduction in performance with increased nutrient loading rates (p =0.0013), whereas T. domingensis performance was significantly limited (p =0.034) even with increased nutrient loading rates. T. procerum too had increased plant performance with increased nutrient loading rates but this effect was reduced under a fluctuating regime. The morphological response by T. procerum demonstrates that it is mainly limited by the nutrient loading rates and not the water regime. However, it was significantly limited/reduced by its increased turnover rates caused by a stochastic fluctuating water regime. Illustrating that in fact the effects of nutrient enrichment on T. procerum were independent of water regime but bearing in mind that water regime is the primary factor determining the productivity of this species. For those species with higher elevation preferences, e.g. C. gymnocaulos, or low elevation preference, e.g. T. procerum, the effects of nutrient loading are independent of water regime, whereas those species with an intermediate elevation preference, e.g. P. australis and T. domingensis the effects of nutrient loading are largely dependent on the water regime. Amphipoda and Trichoptera selectively fed on succulent semi-emergent macrophytes across sites of average to excellent ecological condition (31-64% to 65-97% of diet), depending on availability. These semi-emergent macrophytes contained the lowest C:N ratio (≈10:1), closest to that of their consumers (≈5:1) and therefore the highest nutritional content. In degraded riverine reaches, there were limited food resources available, hence course particulate organic matter (CPOM) formed the main dietary components of Amphipoda (20-53% of diet) even though it had the highest C:N ratio (≈40:1). At site VP. 1, filamentous algae was the main dietary component of Trichoptera (48-64% of diet) due to its availability and its low C:N ratio (≈14:1) in comparison to the other primary sources available. The imbalanced consumer-resource nutrient ratios in these degraded riverine reaches are likely to impose constraints on the growth and reproduction of their aquatic shredder communities with probable knock-on effects at higher trophic levels. The installation of environmental flows to restore and promote aquatic/riparian plant communities, which in turn would benefit higher trophic organisms, is a viable and realistic management option along selected reaches. Those selected reaches contain a significant aquatic/riparian seed bank and with sufficient physical habitat remaining to promote their germination and establishment. However, the imposition of environmental flows as a control measure to prevent the colonisation and dominance of particular species (T. domingensis and P. australis) was deemed to be redundant as a management technique given the limited water resources available.

Résumé :
Until recently, the concept of green logistics has been disregarded by various logistics and transport companies in South Africa. The study on which this dissertation is based explored the green logistics practices that these companies are currently implementing in terms of the key drivers, benefits and barriers. A quantitative research approach was followed, were a survey (Lime) served as the primary research instrument. A census was conducted among 160 companies in Gauteng. The results of the study revealed a significant difference between SMEs (<200) and large (200 and above) companies with regard to their importance rating on green logistics practices. To achieve the primary objective of the study, a framework in green logistics was drafted for SMEs and large companies in South Africa, which outlined practices and opportunities companies can implement in their own businesses to benefit from ‘going green’. The usefulness of the latter mentioned guidelines needs to be tested in future research.

Résumé :
Submitted in fulfillment of the requirements of the Master of Accounting degree, Faculty of Accounting and Informatics, Durban University of Technology, Durban, South Africa. Durban. South Africa, 2016.
A large number of manufacturing companies adopt the use of the traditional accounting method in their operations. This technique fails to reflect a detailed report of all material losses incurred in their production processes. Worthy of note, is that losses/waste are considered as inefficiencies in manufacturing operations and viewed as a costly venture to the sustainability of the company. This research, therefore, through a case study analysis, examined the efficient/inefficient flow of resources in the production process of an alcoholic beverage company in the Durban metropolis. The study was carried out in order to determine the impact of packaging waste cost in an alcoholic beverage company using the material flow cost accounting technique. Measurements included the input of packaging materials against its output, while giving consideration to waste incurred as losses. The Material Flow Cost Accounting (MFCA) technique, an environmental management accounting tool developed for measuring the flows and stocks of materials of a company and production process in both physical and monetary units, was used to measure the costs of waste on two production lines. MFCA was used to trace all material inputs and categorize them as product or non-product output. MFCA is used to classify the relevant material flows as cost collectors, thereby allocating the costs of the company’s production operations and flows. Different packaging materials that constitute waste on the lines were analyzed using the mixed method approach, which includes observation, questionnaire administration, and analysis of six months production report. Two production lines were considered for sampling, and recommendations were given based on the data analyzed using the SPSS package. The MFCA technique revealed that losses on both production lines were understated, and that, the bottling plant was losing a sizeable amount of monetary value of packaging materials to waste. The MFCA technique also revealed that the traditional costing technique is unable to provide adequate information managers require for strategic cost decision making. MFCA is therefore recommended to assist managers improve production line efficiency and cost savings via accurate waste costing and reduction for corporate sustainability.

Résumé :
South African Air Quality Units are continuously undergoing changes, and improving their performance remains a constant endeavour. In addition, these units are also experiencing several challenges in terms of improving communication across the different spheres, accessing air quality data and using the information to support the decision-making required for efficient management of air quality in South Africa. This study investigated the concept of output efficiency within the South African air quality management context. Models that enable efficient resource allocation can be used to assist managers in understanding how to become efficient. There are, however, few models that focus on the output efficiency of the public sector and air quality management units. The primary purpose of the study was to develop a model to predict the extent to which organisational efficiency could be explained by the percentage of man-hours allocated to a range of management activities. In this study, the development of a model using the logistic regression technique is discussed. Data was collected for two financial years (2005/6 and 2006/7) from the air quality officers in the national, provincial and local spheres of government (N=228). The logistic regression model fitted indicates that the proportion of time spent on knowledge management activities contributes the most to the likelihood of an Air Quality Unit being efficient. The resource allocation model developed will ensure that air quality officers allocate resources appropriately and improve their output performance.

Résumé :
Industrial effluents with high concentrations of heavy metals are widespread pollutants of great concerns as they are known to be persistent and non-degradable. Continuous monitoring and treatment of the effluents become pertinent because of their impacts on wastewater treatment plants. The aim of this study is to determine the correlation between heavy metal pollution in water and the location of industries in order to ascertain the effectiveness of the municipal waste water treatment plant. Heavy metal identification and physico-chemical analysis were done using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and multi-parameter probe respectively. Correlation coefficients of the measured values were done to investigate the effect of the industrial effluents on the treatment plants. Heavy metal resistant bacteria were identified and characterised by polymerase chain reaction and sequencing. Leeuwkuil wastewater treatment plants were effective in maintaining temperature, pH, and chemical oxygen demand within South Africa green drop and SAGG Standards whereas the purification plant was effective in maintaining the values of Cu, Zn, Al, temperature, BOD, COD, and TDS within the SANS and WHO standard for potable water. This findings indicated the need for the treatment plants to be reviewed.The industrial wastewater were identified as a point source of heavy metal pollution that influenced Leeuwkuil wastewater treatment plants and the purification plants in Vaal, Vereenining South Africa. Pseudomonas aeruginosa, Serratia marcescens, Bacillus sp. strain and Bacillus toyonensis that showed 100% similarity were found to be resistant to Al, Cu, Pb and Zn. These identified bacteria can be considered for further study in bioremediation.

Résumé :
Most of the lower River Murray and its floodplain wetlands are impacted upon by degradation caused by river regulation. Increasingly the restoration of these ecosystems and the river water quality has become a high priority for federal and state governments and associated departments and agencies. Public concern is adding to the pressures on these departments and agencies to restore these ecosystems and to sustainably maintain the river water quality. The long term monitoring of floodplain wetlands has been limited, compounding the difficulties faced by managers and decision makers on assessing the potential outcome of restoration options. The role of this project in the broad scheme of restoration/rehabilitation is to contribute to the construction of a model capable of increasing managers and decision makers understanding, and build consensus of potential outcomes of management option. This model was to use available data. The developed model, based on WETMOD developed by Cetin (2001), simulates wetland internal nutrient processes, phytoplankton, zooplankton and macrophyte biomass as well as the interaction (nutrient and phytoplankton exchange) between wetlands and the river. The model further simulates the potential impact management options have on the wetlands, and their nutrient retention capacity, and therefore their impact on the river nutrient load. Due to the limitation of data, wetlands were considered in categories for which data was available. Of these two had sufficient data to develop, calibrate and validate the model. Management scenarios for these two wetlands were developed. These scenarios included, the impact of returning a degraded wetland in a turbid state to a rehabilitated clear state, and the impact the removal of nutrient from irrigation drainage inflows has on wetland nutrient retention, and consequent input to the river. Scenarios of the cumulative impact of the management of multiple wetlands were developed based on using these two wetlands, for which adequate data was available, as “exemplar” wetlands, i.e. data from these wetlands were substituted for other similar wetlands (those identified as belonging to the same category). The model scenarios of these multiple wetlands provide some insight into the potential response management may have on individual wetlands, the cumulative impact on river nutrient load and how wetland morphology may relate to management considerations. The model is restricted by data availability and consequently the outputs. Further, some limitations identified during the development of the model need to be addressed before it can be applied for management purposes. However, the model and methods provide a guide by which monitoring efforts can assist in developing future modelling assessments and gain a greater insight not only at the monitoring site but also on a landscape scale.

Résumé :
Text in English with summary and keywords in English and Afrikaans
The International Organization for Standardization - ISO 14001 environmental standard addresses facets of environmental performance. The implementation of ISO 14001:2015 is aligned with various risks and opportunities, the identification and addressing of which is key in the successful implementation of the ISO 14001:2015 certification. The Durban region is a pollution ‘hotspot’ within KwaZulu-Natal. Assessment of the opportunities and risks of ISO 14001:2015 implementation within the region is key as it can potentially assist with proactive mitigation of risks and the effective utilization of opportunities. The aim of the study is to understand SHERQ (Safety, Health, Environmental, Risk and Quality) managerial perspectives of opportunities and risks of ISO 14001:2015 implementation in Durban, KwaZulu-Natal. The following objectives were outlined: To identify ISO 14001 implementation opportunities and risks internationally and nationally by means of an extensive review of international as well as national literature sources, to generate an evaluation framework to assess SHERQ managerial perspectives of risks and opportunities of ISO 14001:2015 implementation within Durban and to analyse SHERQ managerial responses to the ISO 14001:2015 implementation risks and opportunities within the Durban region. The methods included identifying primary opportunities and risks in ISO 14001:2015 from the literature review through an evaluation framework, thereafter, presenting these in questionnaires distributed among SHERQ managers in Durban via email and LinkedIn. Of 62 questionnaires distributed, 42 participants responded. The respondent’s perspectives were assessed through SPSS identifying key risks and opportunities. Objective 1 was achieved through the literature review in which ISO 14001 implementation risks and opportunities were identified. Objective 2 was achieved by generating the evaluation framework which assimilated implementation risks and opportunities. Objective 3 was achieved through the analysis of the responses of respondents to ISO 14001:2015 implementation risks and opportunities. Study results showed that, in line with international reports, 57.2% of all respondents agreed that the maintenance costs of compliance to the standard are high and 76.2% of respondents shared the perspective that company resources are better managed. Respondents were more agreeable to positive statements, indicating opportunities outweighing the risks. Furthermore, despite the risks, there are opportunities from an industry perspective such as increased investor inputs and increased top management involvement. A follow up study is recommended in the Durban region addressing ISO 14001 implementation risks, opportunities, and their investment impacts in order to further hone in on the organizational implications of certification. From an academic standpoint, multiple studies have posited that ISO 14001:2015 implementation resulted in improved financial outcomes but are associated with high implementation costs and it is recommended that a critical cost versus profits analysis into ISO 14001:2015 implementation be undertaken in the Durban region.
Die Internasionale Organisasie vir Standaardisering se ISO 14001-omgewingstandaard spreek fasette van omgewingsprestasie aan. Die implementering van ISO 14001:2015 is gerig op verskeie risiko’s en geleenthede, en die identifisering en aanspreek hiervan staan sentraal tot die suksesvolle implementering van die ISO 14001:2015 - sertifisering. Die Durban-streek is ʼn besoedlingsbrandpunt in KwaZulu-Natal. Evaluering van die geleenthede en risiko’s van die implementering van ISO 14001:2015 binne die streek is van kardinale belang, aangesien dit moontlik kan help met die proaktiewe vermindering van risiko’s en die effektiewe benutting van geleenthede. Die doel van die studie is om SHERQ-bestuursperspektiewe van geleenthede en risiko’s van ISO 14001:2015-implementering in Durban, KwaZulu-Natal, te begryp. Die volgende doelwitte is uiteengesit: Om ISO 14001-implementeringsgeleenthede en risiko’s internasionaal en nasionaal te identifiseer deur middel van ʼn uitgebreide oorsig van internasionale sowel as identifiseer deur middel van ʼn uitgebreide oorsig van internasionale sowel as nasionale literatuurbronne; om ʼn evalueringsraamwerk te genereer om SHERQ-bestuursperspektiewe van geleenthede en risiko’s van die implementering van ISO 14001:2015 te evalueer, en om SHERQ-bestuursreaksies op die ISO 14001:2015-implementeringsrisiko’s en -geleenthede te ontleed. Die metodes het ingesluit die identifisering van primêre geleenthede en risiko’s in ISO 14001:2015 vanuit die literatuurbeoordeling deur middel van ʼn evalueringsraamwerk, waarna dit in vraelyste wat via e-pos en LinkedIn onder SHERQ-bestuurders in Durban versprei is, uiteengesit is. Van die 62 vraelyste wat versprei is, het 42 deelnemers geantwoord. Die perspektiewe van die respondente is beoordeel deur middel van SPSS se identifisering van die belangrikste risiko’s en geleenthede. Doelwit 1 is bereik deur middel van die literatuuroorsig waarin ISO 14001-implementeringsrisiko’s en -geleenthede geïdentifiseer is. Doelwit 2 is bereik deur die evalueringsraamwerk te genereer wat implementeringsrisiko’s en -geleenthede geassimileer het. Doelwit 3 is bereik deur die antwoorde van respondente op ISO 14001:2015 implementeringsrisiko’s en -geleenthede te ontleed. Studieresultate het getoon dat, in ooreenstemming met internasionale verslae, 57,2% van alle respondente dit eens was dat die onderhoudskoste van die nakoming van die standaard hoog is en dat 76,2% van die respondente die perspektief gedeel het dat bronne van die maatskappy beter bestuur word. Respondente het meer met positiewe stellings saamgestem, wat daarop dui dat geleenthede swaarder weeg as die risiko’s. Ten spyte van die risiko’s, is daar ook vanuit ʼn bedryfsperspektief geleenthede, soos verhoogde beleggersinsette en verbeterde hulpbronbestuur. ʼn Opvolgstudie word aanbeveel om ISO 14001-implementeringsrisiko’s en geleenthede en die beleggingsimpak daarvan aan te spreek. Vanuit ʼn akademiese oogpunt het veelvuldige studies aangevoer dat die implementering van ISO 14001:2015 verbeterde finansiële uitkomste tot gevolg het, maar dat dit met hoë implementeringskoste gepaard gaan, en dit word aanbeveel dat ʼn kritieke koste-versus-wins-analise in die implementering van ISO 14001:2015 in die Durban-streek onderneem word.

Phosphorus retention was measured in five pilot-scaled constructed wetlands with different configurations in terms of macrophyte species and substrates in order to evaluate the phosphorus removal efficiency of water plants and substrates in experimental ponds; assess the contribution of macrophytes to phosphorus removal through direct uptake, modification of water chemistry and impacts on the phosphorus adsorption characteristics of substrate; and, contribute to the optimal design and operation of constructed wetlands for the treatment of agricultural drainage water.
