Full textAbstract:
Many industrial processes routinely release radionuclides into the environment. Such emissions may be recognised in the inventory phase of Life Cycle Assessment (LCA), but they are rarely carried forward to the Life Cycle Impact Assessment (LCIA) phase because a standard approach for assessing their impact is still lacking. The aim of this article is to collect and critically analyse radiological impact assessment methodologies to establish a basis for developing a standard approach. Seven methodologies are reviewed. Amongst these, the human health damages approach is the only methodology to date to be included in LCIA methodologies. Furthermore, five of the reviewed methodologies are concerned with impacts on humans, whilst the remaining two address effects on the environment. The article concludes that even though a number of methodologies are currently available, none is suitable as the basis for a standard procedure in LCIA. Two main features have been identified as crucial: the ability to treat all types of waste forms by which radionuclides can be released and the use of a fate analysis that returns average (rather than worst case) estimates of impacts. In light of the findings of this review, a novel framework for radiological impact assessment on humans has been devised; its development is being pursued by the authors.

Full textAbstract:
Aimed at few reflections on the scenario characteristics in the most methods of LCA, this paper presents a new approach taking specific information of scenario into account in the environmental impact of product. By analyzing the relation between scenario and environmental impact, the attributes of space, time and person are extracted as the most basic characteristics. In order to avoid the deficient of science modeling between the scenario attributes and the environmental impact processes and to use conveniently, the concept of scenario characteristic coefficient is proposed and the three types of coefficients are expressed in detail applying the existing data or statistic. The method of LCIA considering scenario characteristics is presented by integrating the characteristic coefficients into the LCI processes. And this method is applied to study the scenario characteristics of an LCA of electromotor.

Full textAbstract:
Life cycle assessment (LCA) has received attention as a tool to evaluate the environmental impacts of products and services. In the last 20 years, research on the topic has increased, and now more than 25,000 articles are related to LCA in scientific journals databases such as the Scopus database; however, the concept is relatively new in Africa, where the number of networks has been highlighted to be very low when compared to the other regions. This paper focuses on a review of life cycle assessments conducted in Africa over the last 20 years. It aims at highlighting the current research gap for African LCA. A total of 199 papers were found for the whole continent; this number is lower than that for both Japan and Germany (more than 400 articles each) and nearly equal to developing countries such as Thailand. Agriculture is the sector which received the most attention, representing 53 articles, followed by electricity and energy (60 articles for the two sectors). South Africa (43), Egypt (23), and Tunisia (19) were the countries where most of the research was conducted. Even if the number of articles related to LCA have increased in recent years, many steps still remain. For example, establishing a specific life cycle inventory (LCI) database for African countries or a targeted ideal life cycle impact assessment (LCIA) method. Several African key sectors could also be assessed further.

Full textAbstract:
This study presents a life cycle assessment (LCA) study for a buoy-rope-drum (BRD) wave energy converter (WEC), so as to understand the environmental performance of the BRD WEC by eco-labeling its life cycle stages and processes. The BRD WEC was developed by a research group at Shandong University (Weihai). The WEC consists of three main functional modules including buoy, generator and mooring modules. The designed rated power capacity is 10 kW. The LCA modeling is based on data collected from actual design, prototype manufacturing, installation and onsite sea test. Life cycle inventory (LCI) analysis and life cycle impact analysis (LCIA) were conducted. The analyses show that the most significant environmental impact contributor is identified to be the manufacturing stage of the BRD WEC due to consumption of energy and materials. Potential improvement approaches are proposed in the discussion. The LCI and LCIA assessment results are then benchmarked with results from reported LCA studies of other WECs, tidal energy converters, as well as offshore wind and solar PV systems. This study presents the energy and carbon intensities and paybacks with 387 kJ/kWh, 89 gCO2/kWh, 26 months and 23 months respectively. The results show that the energy and carbon intensities of the BRD WEC are slightly larger than, however comparable, in comparison with the referenced WECs, tidal, offshore wind and solar PV systems. A sensitivity analysis was carried out by varying the capacity factor from 20–50%. The energy and carbon intensities could reach as much as 968 kJ/kWh and 222 gCO2/kWh respectively while the capacity factor decreasing to 20%. Limitations for this study and scope of future work are discussed in the conclusion.

Full textAbstract:
The inconsistency caused by different life cycle impact assessment (LCIA) methods is a long-term challenge for the life cycle assessment (LCA) community. It is necessary to systematically analyze the differences caused by LCIA methods and facilitate the fair comparison of LCA results. This study proposes an effective method of conversion factors (CFs) for converting the results of 8 LCIA methods for 14 impact categories and then demonstrates its application in the construction sector. Correlation analyses of the datasets of construction materials are conducted to develop CFs for the impact categories. A set of conversion cards are devised to present the CFs and the associated correlation information for the LCIA methods. It is revealed that the differences between LCIA methods are largely caused by the characterization methods, rather than due to the metrics. A comparison based only on the same metrics but ignoring the underlying LCIA mechanisms is misleading. High correlations are observed for the impact categories of climate change, acidification, eutrophication, and resource depletion. The developed CFs and conversion cards can greatly help LCA practitioners in the fair comparison of LCA results from different LCIA methods. Case studies are conducted, and verify that by applying the CFs the seemingly incomparable results from different LCIA methods become comparable. The CF method addresses the inconsistency problem of LCIA methods in a practical manner and helps improve the comparability and reliability of LCA studies in the construction sector. Suggestions are provided for the further development of LCIA conversion factors.

Purpose Nowadays, hydroponic cultivation represents a widely used agricultural methodology. The purpose of this paper is to study comparatively on hydroponic substrates. This study is highlighting the best substrate to be involved in hydroponic systems, considering its costs and its sustainability. Design/methodology/approach Seven substrates were evaluated: rock wool, perlite, vermiculite, peat, coconut fibres, bark and sand. Life cycle assessment (life cycle inventory, life cycle impact assessment (LCIA) and life cycle costing (LCC)) was applied to evaluate the environmental and economic impact. Through the results of the impacts, the carbon footprint of each substrate was calculated. Findings Perlite is the most impacting substrate, as highlighted by LCIA, followed by rock wool and vermiculite. The most sustainable ones, instead, are sand and bark. Sand has the lower carbon footprint (0.0121 kg CO2 eq.); instead, bark carbon footprint results in one of the highest (1.1197 kg CO2 eq.), while in the total impact analysis this substrate seems to be highly sustainable. Also for perlite the two results are in disagreement: it has a high total impact but very low carbon footprint (0.0209 kg CO2 eq.) compared to the other substrates. From the LCC analysis it appears that peat is the most expensive substrate (€6.67/1,000 cm3), while sand is the cheaper one (€0.26/1,000 cm3). Originality/value The LCA and carbon footprint methodologies were applied to a growing agriculture practice. This study has highlighted the economic and environmental sustainability of seven substrates examined. This analysis has shown that sand can be the best substrate to be involved in hydroponic systems by considering its costs and its sustainability.

Full textAbstract:
Sustainable development has been a subject of global interest when people shift the focus from the economy and productivity only to the economy with consideration of the environment and resources on the earth. Manufacturing industry is one of the most crucial sectors that people focused on to make it more sustainable. However, the sustainability for current existing products are not enough to satisfy the requirement of sustainable development within the modern society. Therefore, an approach to design and to optimise product considering ecological impact is to be developed by this research. After review and comparison of popular LCIA methods and tools, the three-tier sustainable design approach considering human labour ecological impact is developed. Design optimisation with eco-constraints using genetic algorithm is followed. Moreover, from a product life cycle point of view, production may not be the least sustainable section. Use and disposal also play important roles in the whole product life cycle. In this case, Ontology is proposed in the research. It is a powerful tool to collect and exchange data of products and manage the relationships among different parts, properties of products, and suppliers in one specific area such as a factory or an industrial estate. Afterwards, The approach is validated by case study. Finally, the sustainable design approach underpinned with life cycle impact assessment (LCIA) and ontology is developed.

The growing industry of Information and Communication Technology requires higher computing capacity of data centers. The air conditioning in data centers is a key to assure a sustainable computing environment. However, the traditional cooling systems cost large environmental footprints especially on energy consumption and greenhouse gas emissions. As a result, a green innovation of data center cooling solutions is taking place. The telecommunication company Teliasonera is developing a high density data center cooling system - the “Green Room” and has been studying the environmental performance of this system using a Life Cycle approach. As an extension of the previous study, more aspects of the project i.e. the location of the data center, life span, alternative cooling solutions, energy recovery possibilities and uncertainty analysis is explored using Life Cycle Assessment (LCA) methodology. The comparison of locations of the Green Room indicates that the local temperature and electricity production sources are essential factors for the environmental performance of the Green Room. The analysis of the Green Room’s life span reveals that the utilization phase may not always cause the most significant impact during the whole life cycle of the Green Room. If the life span changes, the manufacture phase may predominate the life cycle of the Green Room. The comparative result of alternative cooling technologies addresses that utilizing “natural coolant” (e.g. geo cooling) is a key for sustainable cooling innovation as it could significantly reduce the environmental footprint of the cooling system. Besides, heating a single building (partly) by the waste heat generated from the Green Room could save 30% of cumulative energy input and could reduce more than half of the total environmental impact. Additionally, results uncertainties caused by the choice of different LCIA methods are discussed in the end of the study.<br>Teliasonera's Green Room concept

Full textAbstract:
Cotton is one of the leading fibers in the textile industry due to its superior mechanical qualities. It accounts for high environmental impacts, especially water consumption and scarcity. Since cotton is a significant raw material for IKEA, it had set a target to source from only sustainable sources such as from the Better Cotton Initiative, and recycled cotton. At the same time, IKEA also has a commitment to transition to a circular business, which includes recycling. This comparative and accounting Life Cycle Assessment (LCA) analyzes virgin (two types - conventional cotton and Better Cotton) yarns, and mixed (virgin plus recycled) cotton yarns from some of the top supplier countries of the company, on a cradle-to-gate perspective. Water quantity and quality impacts are analyzed together with climate change. The Life Cycle Impact Assessment (LCIA) shows that there is a proportional reduction in impacts of the mixed yarns as recycled cotton percentage is increased, since the impacts of recycled yarns are much lower than virgin yarns. In virgin conventional yarns, the main stages that contributed the most to the impacts were cotton cultivation and spinning. Irrigation used in cotton cultivation accounted for the most impacts in water availability. For water quality, the impacts were mostly coming from electricity use and direct field emissions from cotton cultivation. In addition, this study demonstrated that there were high differences between the impacts in the countries studied. The results also suggested that there were water savings by using Better Cotton compared to conventional cotton yarns.<br>Bomull är en av de vanligaste fibrerna i textilindustrin på grund av dess överlägsna mekaniska egenskaper. Den orsakar dock hög miljöpåverkan, särskilt vattenförbrukning och -brist. Eftersom bomull är ett viktigt råmaterial för IKEA, har de satt ett mål att endast använda hållbara källor, som från Better Cotton Initiative, och återvunnen bomull. Samtidigt har IKEA också åtagit sig att övergå till en cirkulär affärsmodell som inkluderar återvinning. Denna jämförande studie beaktar livscykelanalys (LCA) och analyserar jungfruligt garn (två typer - konventionell bomull och Better Cotton) och blandat bomullsgarn (jungfru plus återvunna) från några av företagets främsta leverantörsländer ur ett vagga-till-port-perspektiv. Vattenmängder och kvalitetseffekter analyseras tillsammans med klimatförändringar. Livscykelbedömningen (LCIA) visar att det finns en proportionell minskning av effekterna av de blandade garnerna när andelen återvunnen bomull ökar, eftersom effekterna av återvunnet garn är mycket lägre än jungfruliga garner. I konventionellt jungfruligt garn var bomullsodling och spinning de främsta stegen som bidrog mest till effekterna. Bevattning som används vid bomullsodling svarade för de största effekterna på tillgången till vatten. För vattenkvaliteten kom effekterna huvudsakligen från elanvändning och direkta utsläpp från bomullsodling. Dessutom visade denna studie att det fanns stora effektskillnader mellan de studerade länderna. Resultaten antydde också att det fanns vattenbesparingar genom att använda Better Cotton jämfört med konventionella bomullsgarn.

On a national level, the Swedish Transport Administration (STA) constitute the responsibleauthority for national long-term infrastructure planning in Sweden and therefore has animportant role for limit the environmental load from domestic transport. STA Road Ferries isresponsible actor within STA, for national infrastructure planning connected to public marinetransport and has formulated the goal of net zero GHG emissions by year 2045 for the ferryfleet. Today, yearly operation causes around 38,400 tons CO2-equivalents. Emissions fromconstruction, maintenance and deconstruction of road ferries are yet unknown. In order to reachclimate neutrality, identification of emissions from a life cycle perspective is needed. This study analyses environmental performance of a standard road ferry from an LCAperspective to be used as a baseline in future work towards climate neutrality. The LCA wasconducted in SimaPro 8.4.0 and evaluated thorough EPD (2013) methodology according to theEN 15804 standardisation. The report gives initial baseline values for the road ferry Neptunus and identifies daily operationas major hotspot in terms of total environmental impact from analysed impact categories, butalso construction phase is of importance to consider. The study further concludes that based onlong term goal and vision as STA Road Ferries has formulated them to today, a combination ofchange in construction in terms of material choices and design, together with changed fuelalternative is considered necessary in order to reach Vision 45. Future studies are recommended on this subject to reach the long term goal and vision. Forexample, studies that complement the developed model with more project specific process dataand include more components, and comparative LCA’s between different fuel alternatives.<br>Trafikverket är den aktör och myndighet som ansvarar för den långsiktiga, nationellainfrastrukturplaneringen i Sverige och som därför har en viktig roll i begränsandet avmiljöpåverkan från landets transportsektor.

Studien identifierade den dagliga driften som en betydandehotspot för den totala miljöpåverkan utifrån de analyserade påverkanskategorierna, men ävenatt konstruktionen är en viktig del av livscykel att ta hänsyn till. Studien visar vidare att ettkombination av en förändrad konstruktion samt val av bränsle är nödvändigt för att nå delångsiktigt uppsatta målen som finns inom Färjerederiet i form av Vision 45. Framtida studier inom detta område är rekommenderat för att nå de långsiktigt uppsatta målen.Till exempel kan vidare studier göras för att komplettera den upprättade modellen med merprojektspecifik processdata och inkludera fler komponenter, samt utföra jämförandelivscykelanalyser mellan olika bränslealternativ.

Full textAbstract:
Soil and freshwater are two absolutely essential resources for ecosystems and humanity. Agriculture depends very much on these resources, and so, without their correct management, farmland practices can trigger many adverse impacts on the environment and jeopardise the availability of soil and water for future agricultural activities. Agricultural lands represent only 12% of the world’s land area. However, roughly 70% of water withdrawals from nature are for irrigated agriculture and 30-40% of the agricultural land is affected by soil degradation. Desertification, irreversible soil degradation, is one of the main problems for sustainability in drylands, areas that cover 40% of the earth’s surface. For these reasons, the environmental impacts of the use of water and land by agricultural activities should be measured.
Life cycle assessment (LCA) is a method to construct the environmental profile of production systems. It was initially developed for industrial production, but a considerable amount of research has been undertaken in recent years to adapt LCA to agricultural systems as well. Conventional LCA methodology does not determine the environmental impacts of water and land use, which is a very significant shortcoming when evaluating the environmental performance of agricultural systems. Furthermore, contrary to other global environmental impact categories such as global warming, the environmental impacts of water and land use vary in every location of the globe, depending on the spatio-temporal conditions of the location, requiring therefore an extension of current LCA methodology.
This thesis focuses on the development of the LCA methodology to incorporate the environmental impacts arising from the use of water and land. The spatio-temporal variability of these resources is taken into account in the proposed methods using the complementary tool of geographic information systems (GIS). For water use, two screening frameworks are built to capture the impacts of soil-water consumption by plants, when, until now, efforts have been directed towards evaluating the environmental impacts of irrigation water consumption. For land use, a multi-indicator approach for a new impact category, desertification, until now never modelled in the LCA context, is provided, as well as a methodology for including soil erosion impacts, in which the soil loss has been related to the loss of organic carbon, as a measure of the soil quality, and finally, to the loss of biomass productivity of ecosystems. The methods developed deal with the life cycle inventory (LCI) and the life cycle impact assessment (LCIA) phases.
In addition, to verify the applicability of the developed location-dependent methods and characterisation factors, these are applied to agricultural crop rotations with energy crops growing in Spain, with the aim of quantifying the side effects of producing bioenergy on the disputed water and land resources in the country. The outcomes indicate that there is no best solution of a single crop rotation grown in a specific location capable of minimising water and land use environmental impacts simultaneously. This is because, firstly, rainfed crop rotations exhibit higher land use related impacts but, in contrast, they are not irrigated. And secondly, locations with more surface, ground and soil water reserves are subjected to more intensive and erosive rainfalls, thus, to higher land use damages.
Among other important follow-up lines of research, future work should focus on the study of suitable functional units for agricultural LCA, calculate the uncertainties of the developed methods as well as try to identify a feasible and relevant geographical scale at which to address the spatial differentiation of the characterisation factors for water and land use impacts, and in general, for any location-dependent impact category.<br>Suelo y agua dulce son dos recursos imprescindibles para los ecosistemas y la humanidad. La agricultura depende de la disponibilidad de estos recursos, que por tanto, debe gestionar correctamente. En caso contrario, las prácticas agrícolas pueden provocar impactos adversos en el medio ambiente y poner en peligro la disponibilidad de suelo y agua para futuras actividades agrícolas. Los suelos agrícolas representan sólo el 12% de la superficie terrestre mundial. Sin embargo, aproximadamente el 70% de las extracciones de agua de la naturaleza se utilizan en la agricultura de irrigación y el 30-40% de los suelos destinados a la agricultura están degradados. La desertificación, entendida como la degradación irreversible del suelo, es uno de los mayores problemas para la sostenibilidad de las tierras áridas, áreas que cubren el 40% de la superficie terrestre. Por estos motivos, deben evaluarse los impactos ambientales debidos al uso del suelo y del agua en la agricultura.
El análisis de ciclo de vida (ACV) es un método para evaluar el perfil ambiental de sistemas productivos. El ACV se desarrolló inicialmente para estudiar la producción industrial, pero en los últimos años la investigación se ha dirigido a la adaptación del método para poder aplicarlo también en los sistemas agrícolas. La metodología convencional de ACV no determina los impactos ambientales debidos al uso del suelo y del agua, siendo ésta una importante deficiencia para evaluar el perfil ambiental de los sistemas agrícolas. Además, al contrario de otras categorías de impacto ambiental global, como el calentamiento global, los impactos ambientales derivados del uso del suelo y del agua son distintos en cada lugar del planeta, en función de las condiciones espacio-temporales del sitio. Por tanto, es necesario extender la metodología actual de ACV.
Esta tesis se centra en el desarrollo de la metodología de ACV para incorporar los impactos ambientales resultantes del uso del suelo y del agua. La variabilidad espacio-temporal de estos recursos se tiene en cuenta en los métodos propuestos utilizando la herramienta complementaria de los sistemas de información geográfica (SIG). Para el uso del agua, se presentan dos métodos de aproximación para medir los impactos debidos al consumo de agua de las reservas del suelo, cuando, hasta la fecha, los estudios han intentado evaluar los impactos ambientales debidos al consumo de agua para la irrigación. Para el uso del suelo, se propone una aproximación multi-indicador para modelar el impacto de la desertificación, una categoría nunca antes incluida en ACV, así como una metodología para incluir los impactos de la erosión del suelo, donde la pérdida de suelo se relaciona con la pérdida de carbono orgánico, como medida de la calidad del suelo, y finalmente, con la disminución de producción de biomasa de los ecosistemas. Los métodos desarrollados comprenden las fases de inventario de ciclo de vida (ICV) y de evaluación de impacto de ciclo de vida (EICV).
Además, para comprobar la aplicabilidad de los métodos regionalizados de ACV y de los factores de caracterización desarrollados, estos se aplican en rotaciones de cultivos con cultivos energéticos en España, con el objetivo de cuantificar los efectos colaterales de producir bioenergía sobre los recursos suelo y agua, muy disputados en el país. Los resultados revelan que no hay una solución idónea, con una rotación de cultivos sembrados en una zona específica del país, que sea capaz de reducir, simultáneamente, los impactos ambientales debidos al uso de suelo y agua. Esto se debe, en primer lugar, a que los cultivos de secano muestran mayores impactos relacionados con el uso del suelo, pero, al contrario, no utilizan agua de irrigación. Y en segundo lugar, a que las zonas con más reservas de agua en superficie, acuíferos y suelos están también sometidas a lluvias más intensas y erosivas, y en consecuencia, a un mayor deterioro del suelo.
Entre otras importantes líneas de investigación a seguir, próximos trabajos deben centrarse en el estudio de unidades funcionales adecuadas para el ACV de sistemas agrícolas, el cálculo de las incertidumbres de los métodos desarrollados en la tesis, así como en la identificación de una escala geográfica significativa y de aplicación factible que aborde la diferenciación espacial de los factores de caracterización para los impactos del uso del suelo y del agua, y, en general, para cualquier categoría de impacto ambiental regional.

Purpose – The purpose of this research is to investigate how manufacturing organisations can decrease their environmental impact in the supply chain. To meet the purpose, two research questions were formulated: 1. How can a manufacturing organisation reduce its environmental impact caused by transportation? 2. How can a manufacturing organisation reduce its environmental impact caused by production? Method – To provide the opportunity to reach a conclusion and to create a basic understanding of the research area, a literature review was conducted, which formed the basis of the theoretical framework. Through a case study at a manufacturing organisation, interviews and document analyses were used as sources for empirical data. In order to develop solutions and recommendations, collected data and theoretical framework were analysed and discussed. Findings – The research findings indicate that there are several possible measures to implement to reduce an organisation's environmental impact in the supply chain. A decisive factor is creating a holistic and fundamental understanding of sustainability and enabling everyone involved to work according a common view and in the same direction. In addition, a requirement to pursue the same goal is that all stakeholders are involved where a prerequisite is a well-functioning internal communication. Implications – The research did not contribute to any new theories, but through the research analysis, statements and theories from previous research were strengthened. The research suggests actions that can be used for organisations to reduce their environmental impact, but also to increase the understanding of why actions should be implemented. Society has an important responsibility for motivating and provide conditions for manufacturing organisations to reduce their footprint. This research is considered to lead to an improved environment in the form of lower emission levels where both organisations and the entire community take responsibility for the planet. Limitations – The case study is designed as a single-case study which, from a validity perspective, is not considered as advantageous as a multiple case study because the results are difficult to generalize. In order to strengthen the study's reliability, several functional units and / or organisations could have been included in the study.

The focus of this paper is to present life-cycle assessment (LCA) of a TV/VCR remote, including alkaline batteries, and to compare the environmental impacts with a redesigned remote consisting of a solar cell. LCA is a very helpful tool in identifying the most important factors for improving product sustainability. The remote considered in this study can control both television and video cassette recorder. This remote is manufactured in Malaysia and exported to the United States. Its life-cycle system includes raw material, parts, shipment, use phase and waste treatment; its life-cycle impact assessment (LCIA) is performed using SimaPro 7.1 and employing the TRACI method. LCA uncertainty analyzing is performed for both remotes utilizing Monte Carlo simulation in SimaPro 7.1. LCA result shows use of alkaline battery affects most obviously in environmental impacts. In Eco-design remote model, both energy type and raw materials changed. Environmental impacts reduce in five categories in redesigned remote. This paper: 1) presents a prototype design for product using solar cell; 2) presents a novel method for designers to determine raw materials to improve product sustainability in designing stage; 3) provides suggestions for manufacturers to improve product sustainability through reuse of solar cell or a leasing strategy.

In industrialized countries, packaging waste is one of the major issues to deal with, representing around 35% of the total municipal solid waste yearly generated. Therefore, an analysis and an environmental assessment of packaging systems are necessary. This paper aims at analyzing and comparing the environmental performances of two different packaging for domestic hoods. It shows how, through a packaging redesign, it is possible to obtain a reduction of the environmental impacts. This study has been performed in accordance with the international standards ISO 14040/14044, by using attributional Life Cycle Assessment (LCA) from Cradle to Gate. The functional unit has been defined as the packaging of a single household hood. Primary data have been provided by a household hood manufacturer, while secondary data have been obtained from the Ecoinvent database. LCA software SimaPro 8.5 has been used to carry out the life cycle assessment, and ReCiPe method has been chosen for the life cycle impact assessment (LCIA) stage. The results have shown the new packaging model being able to cut down the environmental impacts of approximately 30%. These outcomes may be used by household manufacturers to improve performances and design solutions of their different packaging.

Full textAbstract:
The objective of this paper is to determine and compare the environmental impacts of two toasters: standard and eco-friendly. The most rapidly growing sector for the e-waste world comes from Electronic household products. More than 2 million tons of electronic products are disposed off as solid waste to landfills in the US alone. The demand for energy supplies has been rapidly increasing in the past decade. Strict legislative measures should be enforced to protect the environment by making industries collect back the manufactured products at the End-of-Life (EOL) from the users and recycle the products. If these necessary steps are not taken, then these e-wastes will impose serious threat to society and the environment. In order to re-design environmentally friendly products and facilitate sustainable take-back planning, current products need to be evaluated for their environmental impacts. One of the widely used methodologies to assess the environmental impacts of a product is called Life Cycle Assessment (LCA). LCA is a cradle to grave approach for assessing the environmental impacts of a product. The cradle to grave approach includes raw material phase, manufacturing and assembly phase, use phase, recovery phase and disposal phase. The system boundary for LCA presented in this paper includes material phase, manufacturing phase, use-phase and disposal phase. The functional unit for the LCA is entire life of the toaster which is one year based on manufacturer’s warranty which also includes the rate of usage. The environmental impacts from the two toasters as presented in this paper include eutrophication, acidification, energy-use and global warming. The use phase energy impact is experimentally determined.

Abstract The life cycle assessment (LCA) of a middle-class household of 5 members in Guayaquil, Ecuador was performed in order to identify the life cycle stages and activities with higher environmental burdens. LCA is a quantitative tool for assessing the environmental performance of products or systems during its life span, through the compilation and further evaluation of the inputs, outputs, and potential environmental impacts. The life cycle of the house included a 50-year lifespan house divided into three stages: pre-occupation, occupation, and post-occupation stage. The type of house chosen for the analysis represents the current trend of urban growth and planning of the city, which is pointing towards residential zones and housing plans far away from central areas. The notion of household metabolism is associated with the occupation stage. Household metabolism refers to all flows of matter and energy related to anthropogenic activities conducted on a household, which is a socio-economic entity that consists of people living together occupying a dwelling or part of it. Households are key entities of the anthroposphere because the sum of all private households is the process on which all other processes depend on and serve directly or indirectly. The total energy use and emissions for which the sum of households is responsible reflects the importance of considering its influence when assessing the environmental impact of dwellings. Five energy case scenarios were analyzed. These included different energy mixes and the use of inductive cookers as an alternative to those that use liquefied petroleum gas (LPG), which are the most used in Ecuador. The influence of the energy production structure of the country on the environmental impact of the household is supported by the results. A higher share of hydroelectricity in the energy mix, compared with the share of thermal electricity, presented lower environmental impacts in most categories. Public policies that encourage a shift towards a cleaner electricity production technology may decrease the overall environmental impact of households and buildings. The occupation stage entails the highest contribution to all impact categories, e.g. 88% of global warming potential (GWP), followed by the pre-occupation stage, contributing 10% of GWP. Food consumption has not been considered in reviewed studies, although it represents the highest environmental burden within the occupation stage of the house, followed by electricity, and gas use: 43, 27, and 20% of GWP respectively. The results support the importance of including household metabolism in LCA studies due to the high environmental burden associated with it, and the influence of the electricity production structure of the country on the life cycle impact of households.

This paper presents a comprehensive life cycle assessment (LCA) study of heavy duty off-road equipment. The machine studied here is a typical piece of diesel construction machinery equipped with the iT4 (interim Tier 4) certified diesel engine. Two life cycle impact assessment methods, Eco-Indicator 99 and IPCC 2007, are used to calculate the environmental impact and global warming potential associated with the machine’s life cycle, from material extraction to end-of-life recycling and disposal. Due to fuel consumption and emissions, machine utilization during the usage phase is expected to account for most of the total environmental impact. However, the impact from usage can vary greatly, depending on how customers use the machine. To take into account various machine usage patterns, this LCA study performs two sensitivity analyses, varying the load factor and varying the fuel consumption rate, respectively.

Increasing concerns about global warming, resource depletion, and ecosystem degradation are pushing manufacturing enterprises to consider environmental impacts of the products they make. Tools such as Life Cycle Assessment (LCA) has been developed to quantify environmental performance of a product, yet the implementation of LCA requires a significant amount of time/resources and its potential in assisting eco-design has been limited. Research has been done to conduct automatic LCA using the simplified database for electronics or to investigate the environmental impact of electricity consumption in a manufacturing process. However, a comprehensive and automated approach is in need to perform LCA analysis for a product considering all related materials and manufacturing processes. In this research, a framework for automating LCA analysis for eco-friendly product design has been developed and implemented with a computer program. A case study has been conducted using the proposed automatic LCA tool to perform life cycle analysis in the design process. The result of the tool can, with minimal time required, provide detailed distribution of life cycle impact indicators among direct inputs and assist in making design decisions to reduce the environmental footprints.

Nowadays, almost every family has one electric rice cooker, thus making electric rice cooker one of the most popular household appliance in our society. If the product is not designed ecologically and is used heavily, then the product may lead to large ecological impact to our environment. To assess a product’s environmental impacts, Life Cycle Assessment (LCA) methodology is utilized. However, to the best of the authors’ knowledge, for one such technology (electric rice cooker), no complete LCA studies have existed by far. Therefore, the question about the electric rice cooker’s environmental performance is still open. This paper presents an LCA study for the complete life cycle of an electric rice cooker with the power 500Watts as the functional unit. In order to conduct LCA study, the whole life cycle of electric rice cooker was divided into four primary phases: raw materials acquisition, product manufacturing, product utilization and final disposal. To facilitate the data collection and LCA implementation, the whole life cycle system was classified as two subsystems — background system and foreground system. Based on the proposed method, primary data and environmental impact calculation was aided by Simapro 7.2 software. In the light of the Ecoindicator-99 methodology, eleven impact categories (Carcinogens, Resp. organics, Resp. inorganics, Climate change, Radiation, Ozone layer, Ecotoxicity, Acidification, Land use, Minerals, Fossil fuels) were used for the classification and characterization of the life cycle impact assessment. In this paper, the LCA study was found as a very helpful tool to define ecodesign measures for this product. Several measures are suggested to the manufacturers to implement the ecodesign in the future: 1) Use recyclable plastics in the minor parts and hidden components, such as switcher, handle etc.; 2) Reduce the number of different materials in packaging; 3) Avoid incompatible plastics during recycling; 4) Minimize the volume of the heat plate on the premise of meeting the rated heating power.

The Packaging industry is one of the largest industries in the world and is associated with many environmental concerns. To reduce its environmental impacts, designing sustainable packaging has been one of the top priorities in packaging industries. A common tools for evaluating the environmental impact of a package design is the Life Cycle Assessment (LCA) which provides information on environmental impacts for different indicators. However, making decisions based on the LCA results leaves us with major challenges. First, the LCA tools should consider various uncertainties such as measurement and data quality. Second, the LCA may give conflicting results on different environmental impact factors. To address these issues, a ranking based decision making framework is proposed in this paper. Within this framework a Probabilistic Pareto Selection method is introduced to select the Pareto Front with uncertainty first. Then, the Ranking based Rate of Substitution is implemented in the decision making process in order to select the best design options based on the trade-off of each Pareto design. Tow case studies are presented to demonstrate the functionality of this framework.

As global environmental concerns increase, industries continue to respond prominently to meeting sustainable practice standards through technological innovations and new business models. By implementing sustainable practices companies can create a competitive advantage and ultimately drive profitability in addition to mitigating environmental impacts. However, this potential is limited because current comprehensive environmental metrics, including Life Cycle Assessment (LCA), cannot be completed until after the product bill of materials is developed and the manufacturing process has been defined. In addition, the current LCA standards do not provide practitioners with a sufficiently standardized method of conducting an assessment, which makes its application to product development less reliable. This research develops a framework by which environmental impacts of a product system can be assessed and addressed during product development using a more standardized and precise LCA method. The basis of this method integrates systems engineering tools and a functional analysis based approach to LCA. Using this framework, designers can easily develop, classify, and explore different product designs based on predictive environmental impacts.

Full textAbstract:
Worldwide interest in using recycled materials in flexible pavements as an alternative to virgin materials has increased significantly over the past few decades. Therefore, recycling has been utilized in pavement maintenance and rehabilitation activities. Three types of in-place recycling technologies have been introduced since the late 70s: hot in-place recycling, cold in-place recycling, and full-depth reclamation. The main objectives of this project are to develop a framework and a life-cycle assessment (LCA) methodology to evaluate maintenance and rehabilitation treatments, specifically in-place recycling and conventional paving methods, and develop a LCA tool utilizing Visual Basic for Applications (VBA) to help local and state highway agencies evaluate environmental benefits and tradeoffs of in-place recycling techniques as compared to conventional rehabilitation methods at each life-cycle stage from the material extraction to the end of life. The ultimate outcome of this study is the development of a framework and a user-friendly LCA tool that assesses the environmental impact of a wide range of pavement treatments, including in-place recycling, conventional methods, and surface treatments. The developed tool provides pavement industry practitioners, consultants, and agencies the opportunity to complement their projects’ economic and social assessment with the environmental impacts quantification. In addition, the tool presents the main factors that impact produced emissions and energy consumed at every stage of the pavement life cycle due to treatments. The tool provides detailed information such as fuel usage analysis of in-place recycling based on field data.

Full textAbstract:
Truck platoons have many benefits over traditional truck mobility. Truck platoons have the potential to improve safety and reduce fuel consumption between 5% and 15%, based on platoon configuration. In Illinois, trucks carry more than 50% of freight tonnage and constitute 25% of the traffic on interstates. Therefore, expected fuel savings would be significant for trucks. Deployment of truck platoons within interstate highways may have a direct effect on flexible pavement performance, as the time between consecutive axle loads (i.e., resting time) is expected to decrease significantly. Moreover, platoons could potentially accelerate pavement damage accumulation due to trucks’ channelized position, decreasing pavement service life and increasing maintenance and rehabilitation costs. The main objective of this project was to quantify the effects of truck platoons on pavements and to provide guidelines to control corresponding potential pavement damage. Finite-element models were utilized to quantify the impact of rest period on pavement damage. Recovered and accumulated strains were predicted by fitting exponential functions to the calculated strain profiles. The results suggested that strain accumulation was negligible at a truck spacing greater that 10 ft. A new methodology to control pavement damage due to truck platoons was introduced. The method optimizes trucks’ lateral positions on the pavements, and an increase in pavement service life could be achieved if all platoons follow this optimization method. Life cycle assessment and life cycle cost analysis were conducted for fully autonomous, human-driven, and mixed-traffic regimes. For example, for an analysis period of 45 years, channelized truck platoons could save life cycle costs and environmental impacts by 28% and 21% compared with human-driven trucks, respectively. Furthermore, optimum truck platoon configuration could reduce life cycle costs and environmental impacts by 48% and 36%, respectively, compared with human-driven trucks. In contrast, channelized traffic could increase pavement roughness, increasing fuel consumption by 15%, even though platooning vehicles still benefit from reduction in air drag forces. Given that truck platoons are expected to be connected only in the first phase, no actions are required by the agency. However, in the second phase when truck platoons are also expected to be autonomous, a protocol for driving trends should be established per the recommendation of this study.

Full textAbstract:
Snow and ice removal are important tasks during the winter season and large amounts of anti-icing and de-icing chemicals are used and there is a critical need to review and synthesize information from the literature to compare and contrast anti-icing and de-icing chemicals to understand their environmental impact and support decision making. The effectiveness, costs, and environmental impact of commonly used and alternative anti-icing and de-icing chemicals were reviewed in this study. Application of anti-icing and de-icing chemicals may increase ion concentrations in soils and change nitrogen cycle, soil pH, and trace metal concentrations, affect surface water and groundwater, and increase public health risks. Life cycle assessment was conducted to quantitively evaluate environmental impact of selected anti-icing and de-icing chemicals. A decision support tool on environmental impact was developed to evaluate environmental impact of anti-icing and de-icing chemicals in ten different environmental impact categories. The results showed the environmental life cycle assessment tool developed in this study can be used to compare multiple environment impacts to support decision making for winter operation chemicals.
