A Framework for Holistic Life Cycle Cost Analysis for Drinking Water PipelinesKhurana, Mayank 18 July 2017 (has links)
Life Cycle Cost Analysis (LCCA) forms an important part of asset management practices and provides an informed decision support. The holistic nature of LCCA includes life cycle assessment (LCA) as an important component alongside economic life cycle cost analysis. The drinking water industry is right now lacking a reliable cost data structure which will ensure that all the utilities capture the same set of cost data. Also, models and tools currently available in the academia and industry are purely deterministic in nature and do not cater to uncertainty in the data. This study provides a framework for a holistic life cycle cost analysis tool which will help drinking water utilities to prioritize the activities and optimize the cost spending of the utility. The methodology includes the development of a cost data structure, a life cycle cost analysis and a life cycle assessment model in the form of an excel spreadsheet. The LCCA model has the capability to compare different pipe materials, installation, condition assessment, rehabilitation and replacement technologies. Whereas, LCA model can compare different pipe materials based on greenhouse gas emissions calculations. The final step of the methodology includes piloting the model with data from utility A. The analysis has been shown in the form of three case studies - comparison of two pipe materials, two pipe installation technologies and two pipe rehabilitation technologies. The case studies provide results in the form of comparison of total life cycle costs for different alternatives and hence a better alternative can be chosen. / Master of Science / The drinking water industry is right now lacking a reliable cost data structure which will ensure that all the utilities capture the same set of cost data.

A holistic life cycle sustainability assessment for bioeconomy regions: Linking regional assessments, stakeholders and global goalsZeug, Walther 21 June 2024 (has links)
Since about 2015 the social, environmental and economic risks and chances of the bioeconomy and economy in general are becoming increasingly the subject of applied sustainability assessments. Under a bioeconomy, a variety of industrial metabolisms, strategies and visions on substituting fossil resources by renewables and hereto associated societal transformations is formulated, characterized as regional bioeconomy if most foreground activities take place in a specific region. Based on the life cycle assessment (LCA) methodology, further social and economic LCA approaches were developed in previous research whereby life cycle sustainability assessment (LCSA) aims to combine or integrate the evaluation of social, environmental and economic effects. In this early stage of rudimentary and combinatory LCSA development, the research questions of this work are to develop a transdisciplinary framework for integrated LCSA for regional stakeholders to assess ecological, economic and social sustainability in one harmonized method, as well as to implement, apply and validate it by two regional case studies.
Therefore, i) the understandings of sustainability and approaches of sustainability assessment in LCA are transdisciplinary reflected and developed, ii) a systemic framework of the important aspects of such assessments is structured by a series of stakeholder workshops, iii) the methods and indicators from existing LCA approaches as well as from bioeconomy monitoring systems are selected, identified and allocated to a sustainability concept of holistic and integrated LCSA (HILCSA), iv) databases for the life cycle inventory and methods for life cycle impact assessment are implemented in a software, as well as v) the model and method is applied and validated in two case studies on laminated veneer lumber production and production of biofuels in central Germany.
Based on previous research, the dissertation provides a theoretically well based and practically applicable framework for integrated life cycle sustainability assessment, an applicable indicator set for regional (product & territorial) bioeconomy assessment, an integration of life cycle impact assessment methods as well as their comprehensive interpretation. Thereby, LCSA is able to identify the contribution of regional bioeconomy product systems to 14 out of 17 Sustainable Development Goals in terms of planetary boundaries, a sustainable economy and societal needs. The presented results on material and energetic use cases of biomass show that integrated assessments are able to deliver a broad and comprehensive analysis of impacts to identify synergies, trade-offs and hot spots of regional bioeconomy. Compared to existing LCA and LCSA methodologies, the added value of the HILCSA methodology is its integrated and holistic character, which [1] allows consistent and comparable data on social, ecological, and economic indicators, [2] identifies synergies and trade-offs between different aspects and SDGs, [3] traces down impacts to regions in the fore-and background systems, [4] as well as allocates and aggregates them to the SDGs to make complexity communicable. Additionally, HILCSA takes social sciences and political economy into account from beginning to interpretation and discussion of results, relating to social, environmental, and economic impacts not only to technologies but also to societal, economic, and political questions.:Part I Overarching Introduction 1

Product System Life Cycle Assessment for Emerging TechnologiesSameer Kulkarni (19832901) 11 October 2024 (has links)
<p dir="ltr">The race to comply with the Paris Climate Accords fueled by the desire to combat climate change and a greater appreciation of balance of ecological systems requires reducing reliance on fossil fuels and transitioning to using clean energy. This transition is expected to be cleaner but be also material intensive. These materials, such as neodymium or graphite, have been deemed critical by the United States, due to their importance to future of the country. Therefore, efforts are being made to diversify their production (by discovering new manufacturing methods) or improve the material efficiency of their applications.</p><p dir="ltr">It is important that these new applications are analyzed for their environmental impact. Life Cycle Assessment (LCA) is widely accepted methodology for conducting environmental assessment on products and processes. Traditional LCA has 4 steps – goal, scope definition, life cycle inventory, and life cycle impact analysis. Applying traditional LCA techniques on these emerging technologies has challenges, as they are still emerging and have demonstrated their potential at various scales – theoretical, lab scale, pilot scale, or small-scale industrial level. Often, the new processes or products are compared against existing conventional manufacturing methods. Therefore, to appropriately assess the impact of these new emerging technologies against current ones, the scope must be extended to include the product or manufacturing system (which is the economic system under which these technologies will operate and compete against). This methodology is applied to 3 technologies at various stages of their development.</p><p dir="ltr">In the first case study, for magnets, by including the importance of energy product to the product system within the LCA, we see that the higher energy product of additively manufactured magnets directly translates to its environmental benefits relative to injection molded magnets. The next case study looked at a novel process to create battery grade graphite, demonstrated at lab scale. This process was scaled to an industrial level and assessed against conventional methods of manufacturing graphite. The scaleup allowed the LCA to identify the molten salt and the graphite anode to be a potential hotspot. Lastly, the potential green marketability of aluminum cerium alloys is investigated. The product system is extended to include the effect of this new application on cerium compound prices and therefore the economic allocation for the LCA. A Nash equilibrium is found based on market dynamics for aluminum cerium alloys to help resolve this issue.</p><p dir="ltr">The case studies show that allowing the product systems to inform the LCA can result in richer results, which help identify hotspots or opportunities for these technologies as they mature and compete against the conventional products or processes.</p>
