    The Effects of Environmental Management Systems on Source Separation in the Work and Home Settings2012In: Sustainability, E-ISSN 2071-1050, Vol. 4, no 6, p. 1292-1308Article in journal (Refereed)
    Abstract [en]

    Measures that challenge the generation of waste are needed to address the global problem of the increasing volumes of waste that are generated in both private homes and workplaces. Source separation at the workplace is commonly implemented by environmental management systems (EMS). In the present study, the relationship between source separation at work and at home was investigated. A questionnaire that maps psychological and behavioural predictors of source separation was distributed to employees at different workplaces. The results show that respondents with awareness of EMS report higher levels of source separation at work, stronger environmental concern, personal and social norms, and perceive source separation to be less difficult. Furthermore, the results support the notion that after the adoption of EMS at the workplace, source separation at work spills over into source separation in the household. The potential implications for environmental management systems are discussed.

    Renewable Energy and Nutrient Valorization from Anaerobic Digestion: Resource-Efficient Solutions2023Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis presents a comprehensive analysis aimed at understanding process performance, methane yield, and key influencing factors within the context of solid-state anaerobic digestion (SS-AD). SS-AD is used to treat organic material with high solids content, which can be challenging to address by alternative methods. The investigation involves modelling and simulation exploring mass and energy balances and the associated environmental implications. To achieve this, a waste management tool, ORganic WAste REsearch (ORWARE) was adapted and validated to suit the unique parameters of SS-AD operating under a plug-flow reactor configuration, representing a specific case study. The search of an optimal feedstock mix that enhances the digestion process and energy performance is highlighted. Findings suggest that feedstock selection significantly affects methane yield in SS-AD systems, and optimizing substrate mixtures can enhance process efficiency. Key considerations include biodegradability and lignocellulosic content. Operational parameters, such as temperature variations, impact the results from the model, while responsiveness of hydraulic retention time and organic loading rate remains limited. A further comparison between a liquid anaerobic digestion (L-AD) vs SS-AD is made, despite similar methane yields, SS-AD outperforms due to higher energy turnover. Additionally, effective management of digestate nutrients is crucial for its biofertilizer use. Beyond the biogas system, the thesis explores interconnected relationships between SS-AD inputs and outputs and their subsequent use as resources for a hydroponic greenhouse production system. The examination of system interconnections and their broader implications emphasizes the importance of comprehensive assessments when integrating biogas systems beyond their conventional applications.

    Integrating EMS into SCM: A Case Study of Methods, Benefits and Barriers at Sandvik Tooling2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The aim of this research is to explore the benefits and barriers of integrating EMS to SCM in Sandvik Tooling. While exploring that, it is intended to gain insights into the methods employed to integrate the systems and find out the type of integration used in practice.

    Design/methodology/approach – Explorative case study method is employed in this research paper. Primary data is obtained through semi-structured interviews and observations. Triangulation, respondent validation, peer review are the principal strategies employed to ensure validity and reliability of this study.

    Findings – Sandvik Tooling employed a composite view of integration in which verbal and documented forms of information exchanged together with novel solutions to provide integration throughout supply chain on the basis of common goals and vision, shared values and resources. Integration is provided with a balanced mixture of interactions and collaborations. Benefits of integration are categorized as environmental, economic, and organizational benefits. On the other side, barriers are presented as internal and external barriers.

    Practical Implications – This research paper has significant practical contributions to businesses with presenting the ways to integrate and analyze these two systems and demonstrate barriers to overcome and benefits to take advantage of.

    Originality/value – Environmental management systems and supply chain management topics received considerable interest among researchers in recent decades. However there is a lack of research about how these two systems can be integrated and what kind of integration will best define this integration type. Analyzing barriers and benefits of integration process will also advance and contribute our knowledge in this research area.

    Identification and testing of potential key parameters in system analysis of municipal solid waste management2010In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 54, no 12, p. 1095-1099Article in journal (Refereed)
    Abstract [en]

    Life cycle assessment (LCA) and life cycle costing (LCC) are well-established methods used for many years in many countries for system analysis of waste management. According to standard LCA procedure the assessment should include improvement analysis, in many cases this is performed by simple sensitivity analyses. An obstacle to perform more thorough sensitivity analyses is that it is hard to distinguish input data important to the results, i.e. key parameters. This paper further elaborates sensitivity analyses performed in an environmental system analysis fora hypothetical Swedish municipality. In this paper, the method to identify and test input data that can be categorised as potential key parameters is described. The method and the results from computer simulations of the identified parameters are presented, and some conclusions are drawn regarding the robustness of the results for environmental impact from municipal solid waste management. The major conclusion is that the results are robust. Changes in results, when changing the preconditions, are often small and the changes observed do not lead to new conclusions; i.e., a change of ranking order between treatment options.

    Implementering av GRI-standarder och riktlinjer: Fördelar och Utmaningar i Hållbarhetsredovisningen: En kvalitativ studie av svenska statliga företag2024Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Title: Implementation of GRI Standards and Guidelines: Benefits and Challenges in Sustainability Reporting. Level: Student thesis, final assignment for Bachelor Degree in Business Administration. Author: Sofia Ivarsson and Sofie Skalberg. Supervisor: Jean Claude Mutiganda. Date: 2024 - january. Aim: Scandinavia occupies a prominent position globally in sustainability reporting. Many companies in Sweden have started to implement GRI as a tool to strengthen their sustainability reporting and improve communication with their stakeholders. The study aims to examine benefits and challenges that Swedish state-owned companies experience when implementing and using the GRI guidelines in sustainability reporting. Method: In this study, a qualitative method with an inductive research approach has been applied, which includes empirical data collection from seven semi-structured interviews with Swedish state-owned companies in various industries. After coding and thematizing the empirical material, the results have been analyzed and interpreted against previous research. Results and analysis and conclusion: Despite the absence of precise legislation, companies often choose to adapt to external guidelines such as GRI. The GRI framework increases transparency, improves companies' credibility and legitimacy. However, challenges include resource-intensive reporting and the risk of focusing too much on criteria instead of real improvements, requiring adaptation to meet the specific needs of companies ahead of CSRD. Contribution of the thesis: The study contributes to an account of how companies experienced the implementation and use of GRI as a framework. In addition, the study provides concrete conclusions and recommendations based on the experiences and insights that companies have gained through the use of GRI in sustainability reporting. Suggestions for future research: In order to gain a broader understanding of GRI, it would have been interesting to explore other companies, beyond state-owned and active companies in Sweden. It would also have been interesting to examine the benefits and challenges companies experience with CSRD.

    Hinder och möjligheter för att öka källsortering av plastavfall från tillverkningsindustrin2020Report (Other academic)
    Abstract [en]

    The consumption of plastics and the management of the generated amounts of plastic waste are two issues that have been some of the most prominent in the environmental debate in recent years. Today, large quantities of plastic waste from the Swedish manufacturing industry is generated that are not sorted for recycling but end up in combustible residual waste going to energy recovery, which means a significant waste of resources. Although large quantities of plastic waste originate from the manufacturing industry, the vast majority of initiatives related to a more resource-efficient management of plastic waste have focused on the plastic waste generated related to consumption. Relatively little focus has been on the primary plastic waste generated from the manufacturing industry. The purpose of this project has been to contribute to increase the source sorting and recycling of plastic waste from the Swedish manufacturing industry. The goals were to identify and evaluate significant barriers faced by the Swedish manufacturing industry to increase the sorting of plastic in Sweden and to propose how the sorting of the plastic waste can increase. The project and its results were based on a survey answered by manufacturing companies, which was supplemented by interviews with waste and recycling actors.

    Global change effects on plant communities are magnified by time and the number of global change factors imposed2019In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 116, no 36, p. 17867-17873Article in journal (Refereed)
    Abstract [en]

    Accurate prediction of community responses to global change drivers (GCDs) is critical given the effects of biodiversity on ecosystem services. There is consensus that human activities are driving species extinctions at the global scale, but debate remains over whether GCDs are systematically altering local communities worldwide. Across 105 experiments that included over 400 experimental manipulations, we found evidence for a lagged response of herbaceous plant communities to GCDs caused by shifts in the identities and relative abundances of species, often without a corresponding difference in species richness. These results provide evidence that community responses are pervasive across a wide variety of GCDs on long-term temporal scales and that these responses increase in strength when multiple GCDs are simultaneously imposed.Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure across multiple ecosystem types, and those that do exist present conflicting patterns. In an unprecedented global synthesis of over 100 experiments that manipulated factors linked to GCDs, we show that herbaceous plant community responses depend on experimental manipulation length and number of factors manipulated. We found that plant communities are fairly resistant to experimentally manipulated GCDs in the short term (<10 y). In contrast, long-term (≥10 y) experiments show increasing community divergence of treatments from control conditions. Surprisingly, these community responses occurred with similar frequency across the GCD types manipulated in our database. However, community responses were more common when 3 or more GCDs were simultaneously manipulated, suggesting the emergence of additive or synergistic effects of multiple drivers, particularly over long time periods. In half of the cases, GCD manipulations caused a difference in community composition without a corresponding species richness difference, indicating that species reordering or replacement is an important mechanism of community responses to GCDs and should be given greater consideration when examining consequences of GCDs for the biodiversity–ecosystem function relationship. Human activities are currently driving unparalleled global changes worldwide. Our analyses provide the most comprehensive evidence to date that these human activities may have widespread impacts on plant community composition globally, which will increase in frequency over time and be greater in areas where communities face multiple GCDs simultaneously.

    DEM Resolution and Roughness Effect in Relation to Model Performance2023In: Geospatial Information Handbook for Water Resources and Watershed Management, Volume II: Methods and Modelling / [ed] John G Lyon; Lynn Lyon, Boca Raton: CRC Press, 2023, 1Chapter in book (Refereed)
    Abstract [en]

    To understand how the produced flood boundaries from hydraulic modeling can be affected by the resolution of the Digital Elevation Model (DEM) and the roughness values used, and how different performance measures can affect the choice of most optimal models, different simulations were conducted using varying pairs of DEM and Manning’s n. Each result was then compared to the reference flood data and analyzed using different performance measures that account for the sizes of inundation (F-statistics), and the distance between the modeled and reference flood (disparity measures). The results showed that the different pairs of DEM resolution and Manning’s n produced different performance scores and flood extents. High-resolution DEMs performed generally better with higher resolution DEMs, while lower resolution DEMs received better performance when paired with lower Manning’s n. The different model performances also produced different combinations having the most optimal performances depending on the assumptions they applied in the computations. Additionally, the results showed that models from coarser resolution DEMs can produce higher maximum scores than higher resolution DEMs. However, when the maps, cross-sectional profiles, and the water surface elevations from the coarser resolution DEMs were compared with the higher resolution DEMs, they are more inaccurate in representing the terrain, flood boundaries, and the water depths. Thus, interpreting model results only based on performance measure, particularly for lower resolution DEMs, may give incorrect conclusion on the optimality of the result. It is important that the flood extent maps, cross-sectional profiles, and the derived water depths are analyzed together with the performance scores to gain better understanding of the reliability of flood model results.

    New perspectives for green and sustainable chemistry and engineering: approaches from sustainable resource and energy use, management, and transformation2018In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 172, p. 227-232Article in journal (Refereed)
    Abstract [en]

    The special volume on green and sustainable chemistry and engineering has fourteen papers that were considered relevant to the present day issues and discussion, such as adequate use of raw materials and efficient energy, besides considering renewable sources for materials and energy; and changing economical canons towards circular economy. Businesses, governments and Society are facing a number of challenges to tread the sustainability path and provide wellbeing for future generations. This special volume relevance provides discussions and contributions to foster that desirable future. Chemicals are ubiquitous in everyday activities. Their widespread presence provides benefits to societies’ wellbeing, but can have some deleterious effects. To counteract such effect, green engineering and sustainable assessment in industrial processes have been gathering momentum in the last thirty years. Green chemistry, green engineering, eco-efficiency, and sustainability are becoming a necessity for assessing and managing products and processes in the chemical industry. This special volume presents fourteen articles related to sustainable resource and energy use (five articles), circular economy (one article), cleaner production and sustainable process assessment (five article), and innovation in chemical products (three articles). Green and sustainable chemistry, as well as sustainable chemical engineering and renewable energy sources are required to foster and consolidate a transition towards more sustainable societies. This special volume present current trends in chemistry and chemical engineering, such as sustainable resource and energy use, circular economy, cleaner production and sustainable process assessment, and innovation in chemical products. This special volume provides insights in this direction and complementing other efforts towards such transition.

    Developing a holistic and panoptic framework for analysing circular economy2021Conference paper (Refereed)
    Abstract [en]

    Circular economy (CE) has become fundamental in accelerating the efforts towards sustainability. CE was first proposed by Leontief in 1928, as way to understand causal relationships in the economic dimension. Recently, CE has mainly focused on environmental issues i.e. closing the material cycle through recovery (3Rs to 9Rs). Literature on this topic has increased over time and a number of bibliometric studies have been carried out. However, the majority of these studies used bibliometric indicators focusing on descriptive analyses of scientific outputs, particularly on yearly trend, keyword co-occurrence, and/or coauthorship.

    This article adopts a combination of a nested approach, with grounded theory's constant comparative analysis as the overall analysis method and a bibliometric analysis within it. A total of 4,045 documents from CE during the period 1999–2019 were retrieved and analysed against an initial framework composed by different levels (economic issues, recovery and CE levels). The iterative process helped to improve the economic category, changing the level category into a scope one, and adding two new categories (scientific collaboration and themes). The results obtained were integrated to propose the holistic and panoptic framework for analysing circular economy for analysing circular economy, which consists of the integration and interconnection of three main components: (1) economy, with cost, productivity, distribution, value creation, and value added; (2) recovery loops from the 3Rs to the 9Rs; and (3) the scope of CE activities, including assessment, review, individual, organisation, process, sector, cluster, and country/region. In addition, assessment and review are transversal categories within scope.

    This paper provides depth to the understanding of the economic, environmental and scope interlinkages of CE literature, so as to better position the CE theory and practice and to detect gaps that should be addressed. Moreover, the study highlights the importance for CE to achieve its potential in helping societies become more sustainable. Thus, theory and practice must take a holistic approach that integrates the economic and environmental dimensions, the scope of CE, and collaboration.

    This research is linked to SDG12 Responsible Production and Consumption, 12.5 (By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse); target 12.6 (Encourage companies, especially large and transnational companies, to adopt sustainable practices and to integrate sustainability information into their reporting cycle), and 12.a (Support developing countries to strengthen their scientific and technological capacity to move towards more sustainable patterns of consumption and production).

    This study contributes to accelerating progress towards SDGs, as more research of CE is needed to examine how corporations can enhance their adaptive capacity, so they can meet sustainability and their company's needs in times of crisis.

    Sustainability drivers in Small and medium-sized enterprise's2020Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Problem: There is little amount of research focused on small and medium-sized enterprise’s (SMEs) and their work with sustainability. Most research on sustainability drivers has been developed on large organizations which makes this thesis provide a perspective on the most important sustainability drivers in SME’s and how they are embedded in SME’s.

    Purpose: The purpose of this thesis is to deepen and enrich knowledge of sustainability drivers in SME’s with the aspects internal and external drivers.

    Method: This thesis has a qualitative and quantitative research approach where the interview included qualitative questions and quantitative rankings of the internal and external drivers by the interviewed SMEs.

    Findings: The findings of the qualitative and quantitative research indicate that SMEs have embedded sustainability in their work by ranking the most important drivers. The highest ranked internal drivers are proactive leadership, company culture and moral and ethical obligations. The highest ranked external drivers are regulation and legislation, customer demands and expectations, society’s raising awareness and market demands.

    Conclusion: The main contribution of the thesis is presented by highlighting the most important drivers in SMEs, external stakeholders might have an idea of which driver influences SMEs to make them sustainable; if sustainability is not embedded in the SME. This thesis did not aim to generalize the findings about SMEs sustainability drivers, but to obtain a deeper insight by the interviewees experiences.

    Analyzing the impacts of last mile mobility and studying the implementation of alternative vehicles in Swedish cities.2022Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    The growing population of cities and the rise of e-commerce are increasing the transportation of both goods and people. This can generate problems such as traffic jams, increased pollution, and lower living standards for citizens. To reduce the negative impacts, a change in last mile mobility could be made, replacing traditional combustion vehicles with electric ones or, ideally, with bikes and cargo bikes. 

    This thesis examines the case of the Swedish cities of Gävle and Uppsala, trying to explain how the last mile affects the lives of their inhabitants, if and why electric vehicles and cargo bikes are implemented (or not), and how authorities can promote their use. For this purpose, after a literature review, some questions were developed, and seven city managers were interviewed: five from Gävle and two from Uppsala. 

    The study shows that city managers are aware of the impacts that the last mile, and mobility in general, has on its inhabitants, and of the need for a shift towards a more sustainable mobility. Despite this awareness, policy makers are not doing everything possible to accelerate the transition. According to city managers, both the public and private sector advocate more for a change of energy source (from combustion to electric vehicles) rather than a model change using bikes. In addition, the study shows the opportunities that the new model based on non-traditional vehicles can offer and the barriers that prevent its implementation. Finally, different measures that could make cities more sustainable are proposed.

    Sustainable collaboration: The impact of governance and institutions on sustainable performance2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 155, no 2, p. 1-6Article in journal (Refereed)
    Abstract [en]

    Collaboration between firms is important to stimulate the transition to a more sustainable society. This special volume shows that collaboration is indeed one of the preferred forms of governance to manage relations between firms in a sustainability context. Collaboration enhances sustainable benefits by creating legitimacy of sustainable technologies, reducing waste and improving environmental and social performance of firms. The institutional environment, in particular environmental laws and regulations, has a beneficial impact on collaboration and relationship management in sustainable supply chains. Two studies in this special volume show, however, that stringent environmental regulations may hinder economic performance and result in outsourcing to foreign suppliers with potential detrimental effects for environmental performance. These negative effects can be overcome by firms that invest in sustainable innovation. This special volume also shows that eco-innovation leads to sustainable benefits, such as lower greenhouse gas emissions.

    Towards Sustainable Shipping: A Sustainability Appraisal of Marine Fuels2022Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    The maritime industry must deal with several challenges and difficulties to tackle climate change. Organisations and companies are pursuing strategies to decarbonize the operations and provide an efficient and sustainable model for the shipping sector that would not damage the natural environment. The International Maritime Organisation (IMO) and the European Union have implemented a set of regulations to tackle the rapid increase of Greenhouse Gas emissions, researching and developing new marine fuel technologies. Decision-making processes have been usually used with the participation of several stakeholders, concluding on an eventual ranking of several alternatives. However, this master thesis assesses with the aid of a Multi-criteria Decision Analysis (MCDA) methodology, and the Distance To Target weighting scheme four marine fuels technologies. It takes into consideration science-based targets, especially the Planetary Boundaries framework and the United Nations Sustainable Development Goals, with the overall goal to assess the robustness of the results and compare them with other conducted analyses. The final results shows that hydrogen is defined as the most sustainable fuel, based on 5 selected criteria, followed by ammonia, LBG and LNG. However, there are differences between conventional MCDA and current research’s results when it comes to the weighting of the sustainability criteria, which is based on assumptions that have been made during the analysis. More accurate data on marine fuel technologies, and specific science-based targets for the maritime industry would assist decision-making methodologies, leading to objective outcomes.

    Proposing a model for the holistic use of sustainability initiatives – a multiple case study2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this research is to investigate how companies address sustainability holistically and compare the practical results to theoretical findings. The holistic approach of sustainability includes four dimensions and five corporate system elements.

     

    Methods: For creating the theoretical framework a literature review was executed. Empirical data was gathered from a multiple case study. In total five case companies have been selected and five interviews have been conducted. Furthermore the interview guideline included a small survey. Empirical data was complemented by information from sustainability reports and companies website.

     

    Main findings: Sustainability is partly executed in differently in practical terms compared to theory research. The differences are mainly explained by the unique use of sustainability initiatives, which are adapted to companies circumstances.

     

    Academic contributions: Previously, only a few researchers investigated the combination of initiatives to provide a holistic sustainability approach. Furthermore a lack of practical research in the field of sustainability has been identified. This thesis contributes to close this gap by investigating five case companies regarding the use of multiple initiatives.

     

    Practical implications: Based on the findings a model was created by the authors. By applying this model and using recommended initiatives companies are able to establish a holistic sustainability approach, involving all sustainability dimensions and corporate system elements.

     

    Limitations: The interviews have been translated from German or Dutch into English, which increases the risk of wrong interpretations. Further the interview involved only one representative per company. Additionally the number of small case study companies and case companies from the service sector might limit the generalization of the results.

    Qualitative analysis of the possibilities of a suggested device for waste compression and grain size reduction at source2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper discusses the possibilities of developing and installing a mechanical wastetreatment device – proposed by the author – intended to be used in residences or wastecollecting points. The device would perform the job of waste classification, grain sizereduction and volume compression off the main municipal waste families at theproduction place, thus, reducing the energy and economic cost in the collection andtransportation processes.

    In the study, the most common sorted types of leftovers produced in municipalities arecategorized and then, separately analysed the treatment to which it is subjected each ofthe type of waste sorted in the Household Solid Waste (HSW). For this purpose, theselection sub-processes they go through before recycling, compost or disposing arespecified and described. The study aims to specify which are the current characteristicsof the collected waste input so as the processing is feasible and correct.

    The current characteristics are compared to the reduced grain size and specific volumethat would bring the Proposed Waste Pre-Treatment (PWPT). This way, it is determinedif the PWPT characteristics are suitable to their integration in the current waste treatmentsystem. Explanations are given regarding the problems found when searching for usabledata about energy consumption as well as cost of collection and transportation of waste.

    The present investigation provides strong evidence that the PWPT device is notapplicable in a widespread way to all types of HSWs, as the characteristics of reducedgrain size and specific volume obtained can not be integrated into the current wastetreatment systems of most of residue types. In case wanting to search for means to reduceenergy consumption as well as cost of collection and transportation of waste, othersolutions for each type of waste should be investigated; these are briefly discussed in thethesis.

    Regional Transport Indicators Used in Sweden for Measurement, Reporting and Verification of CO2 Emissions2015In: Challenges, ISSN 2078-1547, E-ISSN 2078-1547, Vol. 6, no 1, p. 55-70Article in journal (Refereed)
    Abstract [en]

    Established practice is available as a reference for evaluating sustainable transport and CO2 emissions at national, European and global levels, but comparing corresponding systems at the regional and local levels are more challenging. Therefore, this paper analyses the use of indicators, evaluation methods and data availability at local and regional levels for applied policies and measures in transport planning. Sweden is used as a case study. Available data show that total surveys (e.g., vehicle registry data), sample surveys (e.g., interviews) or modelling can be used to develop transport indicators, and that either generated (volume generated in the area) or performed (volume in the area) traffic and transportation is estimated. However, there are limitations with all methods and the design of evaluations needs careful consideration in order to reflect changes in local and regional transport systems and to relate those changes to specific measures and policies. In most cases, survey methods need to be used in order to follow up the most common indicators. All evaluation methods need to be complemented with analyses of a baseline to determine additionality and also potential rebound effects need to be considered, which requires the application of a wider systems perspective.

    A systematic approach to assess the relocation of the business centres to a logistics platform: A case study on DHL Freight AB (Sweden)2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The relocation of logistic companies’ from the inner centres to the logistic platforms significantly affects both the supply chain management and the urban sustainability development. Recently the concept of city logistics and intermodality has received a significant attention from both academics and decision makers. City logistics play a pivotal role to ensure the liveability of urban areas but, in parallel, urban freight transport also has a significant effect on the quality of life in the urban settings. Optimization of urban freight transportation have an important input in the context of sustainability and liveability of cities and urban areas reducing traffic congestion, decreasing road accidents, alleviating CO2 emissions and noise impacts.

    The purpose of this thesis is to evaluate the relocation of a case logistics company from the city centre to a suburban area. To do this, a wide range of literature reviews pertaining the influence of peripheral logistics platform on the city sustainability were investigated. It seems that there are not well-defined models which can make a comprehensive and quantitative assessment in the context of sustainability for the relocation of business premises. Further investigation was done by conducting a case study on DHL, field observation of traffic flow. Based on all the collected information from the relevant sources, a mixed methods research was applied including a qualitative approach and a quantitative approach. A systematic approach was therefore developed in the context of sustainable development which can be used as an assessment tool for the major factors that enlighten the decision makers to consider the relocation of the logistics companies.

    A systematic approach was developed by this thesis which facilitates the assessment of key factors that impact the relocation decision in the context of all the three sustainable aspects: economic, social and environmental development. These impacts represent traffic congestion, time and distance of transportation, emission, cost optimization and transport mobility.

    Assessments of ground subsidence along the railway in the Kashan plain, Iran, using Sentinel-1 data and NSBAS algorithm2022In: International Journal of Applied Earth Observation and Geoinformation, ISSN 1569-8432, E-ISSN 1872-826X, Vol. 112, article id 102898Article in journal (Refereed)
    Abstract [en]

    The 110-kilometer-long Qom-Kashan railway is one of the busiest lines in Iran, passing through the Kashan plain. The majority of Iran's plains have subsided in recent years as a result of uncontrolled groundwater extraction, and the Kashan plain is no exception. In this study, ground surface displacement in the Kashan plain region and its impact on the railway were investigated using New Small Baseline Subset (NSBAS) in up-down and east–west directions using descending and ascending Sentinel-1 data collected between 2015 and 2021. Our results indicate that the Kashan plain is subsiding more than 90 mm/year. The study of the local areas around the railway which passes through the study area revealed that the rate of vertical velocity in some locations reaches –23 mm/year, while the rate of east–west velocity is insignificant and is approximately ±2 mm/year. Additionally, a method for analyzing the railway's stability based on longitudinal profiles along the railway is presented. Our findings suggest that more than 60% of the railway line is subject to variable amounts of subsidence. Additionally, a region of approximately one kilometer of the railway has been classified as a risk zone due to relatively fast local deformation. After examining the effect of various factors, it was determined that uncontrolled groundwater extraction in agricultural areas contributed to the subsidence in this area. Our results show that the presented stability control approach in this study is highly reliable for creating hazard profiles for linear structures, such as railways.

    A new comprehensive map of LCAs for decision makers in China: case study in FAST project2011Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    The starting point for this thesis project is the increasing intense demands of using Life Cycle Assessment (LCA) to improve the environmental performance of projects, i.e. theFive-hundred-meter Aperture Spherical radio Telescope project(FAST project) inChina. As a prevailing systematic and strategic assessment tool, LCA is used to evaluate and assess all environmental impacts of products, services and industrial processes from cradle to grave. It is also well recognized and practiced to achieve the goal of sustainability.

     

    Following the increasing trend of sustainable development, the idea of conducting LCA technique is gaining more support from the governments, local authorities and institutes inChina. Still, recent researches have only focused on the technical issues of this tool as such, rather than the context it is involved in. To give a broader perspective instead, this thesis focuses on how to make the rankings and quantitative eco-files generated from LCAs be understood more effectively and easily by the decision makers. An effective and comprehensive map of life cycle assessment building on the results of life cycle assessment is presented.This map in this thesis is named as CLCA. Through ranking and mapping the complicated and recondite environmental performance information from the LCAs, a holistic and systematic view can be provided to the decision makers. Thus, to some extent, this CLCA approach can lend support to strategic decisions making and sustainable development.

     

    For this purpose, literature on LCA and literature from relevant disciplines are reviewed. The empirical analysis of FAST project sheds light on that it is necessary to develop a new method that can contribute to convertingcomplicated and reconditedata into a comprehensive and visualized one. Therefore, a survey paper based on the literature review and empirical analysis is designed, distributed and collected. Some influential and necessary essentials of the LCA reports for the decision makers are picked out and summarized in accordance with the results of survey papers. This thesis concludes by presenting a new map of LCA reports and suggestions for further research.

    En förstudie om Gävleungdomars relation och attityd till närproducerat livsmedel och dess förpackningar2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    There are many different reasons why consumers buy locally produced foods. Some consumers buy locally produced food nearby, while others buy after-production because they consider that the food has been produced in an environmentally and climate-friendly way. Some consumers buy after-production because it tastes better or that they consider it to be of a higher quality than other foods.

    The purpose of this pilot study is to investigate the relationship and attitude to food that is produced locally, and the attitude they attach to packaging for local food of high school students in Polhem school in Gävle. Also, investigate how local manufacturers in Gävleborg County work today with market communication and packaging design.

    To carry out this study, a quantitative study has been used. The quantitative study is based on two surveys conducted by high school students at the Polhem School in Gävle and local producers in Gävleborg County.

    The questionnaires cover all the theory areas. The theory chapter begins with a background description about MatVärden, an association that works for Gävleborg residents, but also visitors to be able to share the food and drink produced in Gävleborg. Next, the Foodstuffs Strategy 2017 describes food production, consumer demand, packaging design and marketing communications. Each part has a connection with the purpose of the study that will be the basis for the conclusion.

    The empirical material presents the material collected about the quantitative questionnaire survey.

    It has been observed that there is a lack of knowledge among high school students about food produced locally. It also appears in the result that they consider that a colored and more fun packaging attracts more than one ordinary and single-colored.

    Local producers have a hard time reaching out to the stores today because they lack knowledge and communication. They have limited opportunities to work per the traditional models that exist and have shown an interest in increasing their sales and reaching out to the stores.

    Evaluation of an Eco Audit tool - through an LCA of a novel car disc brake2018In: Proceedings of NordDesign: Design in the Era of Digitalization, NordDesign 2018, The Design Society , 2018Conference paper (Refereed)
    Abstract [en]

    Transport of goods and people is increasing and causing strains on the environment. Road vehicles emit exhaust and non-exhaust emissions. One significant contributor to non-exhaust emissions is particulates generated through wear from braking. The particulates originate from the contact surfaces of the pad and the disc. Particulate emission is a known issue with considerable impacts on plant, animal, and human health. In the EU Horizon 2020 LOWBRASYS (a LOW environmental impact BRAke SYStem) project (LOWBRASYS, 2017), one of the objectives was to design a novel disc brake that reduces particulate generation during braking. One of the results is a novel disc brake with disc and pad-materials that indicate a significant decrease in particulate formation during use. This is accomplished by changing the materials of the contact pair regarding composition and coatings (Wahlström, Lyu, Matjeka, & Söderberg, 2017). Materials used in the disc brakes cause environmental impacts during their life cycle. Some parts and processes need for example critical raw materials such as tungsten, cobalt, and more (European Commission, 2017). This paper evaluates a material selection tool with an environmental perspective for product developers called Eco Audit (Ashby et al. 2008). This tool is featured in the CES Edu Pack software provided by Granta Design, Cambridge University (Granta 2018). The purpose of this study is to evaluate if the Eco Audit tool can provide a fast and valid impact assessment from an LCA perspective. Results of the Eco Audit compared to the SimaPro results indicate that it is possible to make valid conclusions. The validity of the tool is connected to the purpose of the study. If the purpose is to identify critical life cycle phases and environmental impacts, then the tool can accurately aid the user. It could potentially be difficult to make valid conclusions when assessing a product with more complex processes or advanced materials. The tool's strengths are the simplicity and easy accessibility for any user. The trade-off is precision, robustness, and representativeness of the target.

    Scrutinising the electric vehicle material backpack2018In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 172, p. 1699-1710Article in journal (Refereed)
    Abstract [en]

    Conventionally the use phase of a road vehicle contributes to more than 70% of the total environmental impact in terms of energy use or emissions of greenhouse gases. This figure is no longer valid concerning electric vehicles and a shift to other life cycle stages and impacts is expected and should be re-evaluated. The goal of this study is to assess the environmental performance of two prototype vehicle drivetrains; an internal combustion engine and an electric motor, from a life cycle perspective. The assessment is performed in a qualitative manner using the Environmentally Responsible Product Assessment (ERPA) matrix. The two vehicles in this study have similar car body construction, providing an excellent opportunity to highlight the significance of material differences in their drivetrains. The internal combustion vehicle demonstrated a better environmental performance in three out of five lifecycle stages (pre-manufacture, product manufacture, and disposal). In all of these stages, the impact of the electric vehicle is determined by the burden of the materials needed for this technology such as rare earth elements (REE) and by the lack of recycling possibilities. The study demonstrated a need to close the material cycle when it comes to Critical Raw Materials (CRM) such as REE which can only be achieved when the technology but also the incentives for material recovery are provided, i.e. by promoting the development of cost-efficient recycling technologies. Moreover, the need for relevant metrics and assessment indicators is demonstrated to be able to compare the two technologies fairly.
