Development of a framework for sustainable management of industrial food waste

Garcia-Garcia, Guillermo January 2017 (has links)
This thesis reports on the research undertaken to increase the sustainability of the management of industrial food waste. The main objective of this research is to develop a systematic framework that can be used by food manufacturers to identify and implement sustainable solutions for food waste management. The research reported in this thesis is divided into four main parts. The first part reviews the literature on ramifications and issues associated with the generation and management of food waste, available options to tackle issues related to food waste, categorisations of food waste and existing methodologies to support food waste management modelling and decision-making with regard to the management of food waste. The second part introduces a framework to identify types of food waste and link them to their most sustainable food waste management solution. The third part presents a food waste management modelling procedure and identifies attributes needed to model food waste management. The fourth part analyses relationships between attributes and provides information flowcharts and a methodology to support the modelling of food waste management systems. The applicability and usefulness of the research have been demonstrated through case studies with two UK food manufacturers: a brewery and a meat-alternative manufacturer. Although the framework presented in this thesis aims at improving food manufacturers waste management, it could be easily adapted to be used in other stages of the food supply chain. In summary, the research reported in this thesis has concluded that food manufacturers generate large amounts of food waste that are managed in a wide range of ways. A systematic framework to analyse types of food being wasted, waste management processes, food manufacturers, waste management processors and sustainability implications of food waste management provides a sound methodology to identify opportunities to improve the management of industrial food waste.

Facilitating Phosphorus Recovery Through Improved Waste Management

January 2016 (has links)
abstract: Phosphorus (P) is an essential resource for global food security, but global supplies are limited and demand is growing. Demand reductions are critical for achieving P sustainability, but recovery and re-use is also required. Wastewater treatment plants and livestock manures receive considerable attention for their P content, but municipal organic waste is another important source of P to address. Previous research identified the importance of diverting this waste stream from landfills for recovering P, but little has been done to identify the collection and processing mechanisms required, or address the existing economic barriers. In my research, I conducted a current state assessment of organic waste management by creating case studies in Phoenix, Arizona and New Delhi, India, and surveyed biomass energy facilities throughout the United States. With participation from waste management professionals I also envisioned an organic waste management system that contributes to sustainable P while improving environmental, social, and economic outcomes. The results of my research indicated a number of important leverage points, including landfill fees, diversion mandates for organic waste, and renewable energy credits. Source separation of organic waste improves the range of uses, decreases processing costs, and facilitates P recovery, while creating jobs and contributing to a circular economy. Food is a significant component of the waste stream, and edible food is best diverted to food banks, while scraps are best given to livestock. Biomass energy systems produce multiple revenue streams, have high processing capacities, and concentrate P and other minerals to a greater extent than composting. Using recovered P in urban agriculture and native landscaping results in additional benefits to social-ecological systems by improving food security, reducing the urban heat island effect, sequestering carbon, and enhancing urban ecosystems. / Dissertation/Thesis / Biomass Energy Facility Spreadsheet / Anaerobic Digester Facility Spreadsheet / Raw Data from Biomass Survey / Individual Responses from Biomass Survey / Raw notes from India case studies / Doctoral Dissertation Sustainability 2016

O objetivo desta dissertação é analisar as partes integrantes do sistema de gerenciamento de resíduos sólidos domiciliares do município de Ilha Solteira - SP, desde a geração dos resíduos sólidos nas residências até a sua destinação final em aterros e/ou separação e comercialização pela cooperativa de materiais recicláveis do município. A pesquisa foi dividida em três etapas. A primeira etapa consistiu em realizar um levantamento de dados sobre a destinação dos resíduos sólidos domiciliares no município de Ilha Solteira – SP. A segunda etapa consistiu em entrevistar os munícipes com o objetivo de levantar qual é o tamanho da parcela da população que realiza a separação dos materiais recicláveis, como estes são acondicionados e quais os materiais que são separados. E a terceira etapa foi a caracterização gravimétrica dos resíduos sólidos domiciliares destinados ao aterro sanitário, segundo o método de quarteamento. A pesquisa forneceu resultados sobre a redução da vida útil do aterro sanitário, a quantidade de materiais com valor econômico que está sendo desperdiçado no aterro e a renda que deixa de ser gerada para as pessoas diretamente envolvidas com a comercialização dos materiais recicláveis. Com os resultados obtidos nesta pesquisa, a municipalidade que opera e gerencia os resíduos sólidos terá informações que poderão subsidiar o planejamento e as ações de curto, médio e longo prazo; no sentido de melhorar a eficiência e as condições econômica, ambiental e social do sistema de gestão dos resíduos sólidos domiciliares de Ilha Solteira – SP / The efficient management of solid waste directly impacts the welfare of the entire population of the city, but especially those working with the collection, separation, and marketing of recyclable materials. The objective of this dissertation is to study the integral parts of the management system of solid waste in the city of Ilha Solteira-SP, from the generation of solid waste in the home until its final destination in landfills and/or separation and the cooperative for marketing recyclable materials of the city. The research will be divided into three phases. The first step will be to conduct a survey of preliminary data on the allocation of household solid waste in the city of Ilha Solteira-SP. The second stage is to interview the townspeople in order to discover what portion of the population carries out the separation of recyclable materials, wich of these are wrapped and which materials are separated. The third step performed is gravimetric characterization of household solid waste destined for the landfill, using methods of quartering. From the results obtained in this research, the municipality that operates and manages the solid waste will have information that could support the planning and the actions in short, medium and long term, to improve the efficiency and effectiveness of economic, environmental, and social management system for solid waste Ilha Solteira - SP. It will be known: the amount of materials with economic value that are being wasted in the landfill, as well as an estimate of the remaining service life of the landfill, and the income that is not generated for the people directly involved with the marketing of recyclable materials

Municipal Solid Waste Management In India: Finding Sustainable Pathways For The City Of Bangalore

January 2013 (has links)
abstract: During the months from June to November 2012, the city of Bangalore was faced with a serious solid waste management (SWM) crisis. In the wake of the upheaval, the state court declared source segregation to be mandatory. Yet, while the legislation was clear, the pathway towards a course of action for the transition was not clear and hence, Bangalore was stuck in a state of limbo. The objectives for this thesis spiraled organically from this crisis. The first objective was to examine the gaps in Bangalore's transition to a more sustainable SWM system. Six particular gaps were identified, which in essence, were opportunities to re-shape the system. The gaps identified included: conflicting political agendas, the exclusion of some key actors, and lack of adequate attention to cultural aspects, provision of appropriate incentives, protection of livelihoods and promotion of innovation. Opportunities were found in better incentivization of sustainable SWM goals, protecting livelihoods that depend on waste, enhancing innovation and endorsing local, context based SWM solutions. Building on this understanding of gaps, the second objective was to explore an innovative, local, bottom-up waste-management model called the Vellore Zero Waste Model, and assess its applicability to Bangalore. The adaptability of the model depended on several factors such as, willingness of actors to redefine their roles and change functions, ability of the municipality to assure quality and oversight, willingness of citizen to source segregate, and most importantly, the political will and collective action needed to ensure and sustain the transition. The role of communication as a vital component to facilitate productive stakeholder engagement and to promote role change was evident. Therefore, the third objective of the study was to explore how interpersonal competencies and communication strategies could be used as a tool to facilitate stakeholder engagement and encourage collective action. In addressing these objectives, India was compared with Austria because Austria is often cited as having some of the best SWM practices in the world and has high recycling rates to show for its reputation. / Dissertation/Thesis / M.S.

Under What Conditions Do Community Demographics Influence Aggregate Recycling?

Kotter, Edward 01 December 2011 (has links)
Diversion rates of solid waste due to recycling and other efforts vary across communities for multiple reasons. Past research has provided demographic and attitudinal profiles of recyclers and non-recyclers at mainly the individual and household levels with some at the community level. Researchers have found both commonalities and variations in these profiles. Studies have also looked at how the structure of a recycling program influences recycling behavior. The question asked here is how community-level demographic and attitudinal characteristics interact with the structure of public recycling programs to influence aggregate rates of recycling participation and diversion in 40 cities in the western United States. The results of this study provide modest support for my hypotheses that when recycling programs are less convenient, demographics and attitudinal characteristics will explain more variation in diversion of waste at the community scale. Similarly, as recycling programs become more convenient, the roles of demographic and attitudinal factors (recycling friendliness) are expected to decrease. This study found increased recycling program convenience and less visible fee assessment structures were associated with higher rates of recycling among cities regardless of their degree of recycling friendliness. When recycling outcomes were cross tabulated with indicators convenience and fee assessment, low rates were generally found among cities with low program convenience and high rates were generally found among cities with high program convenience. Cities with less convenient programs were more likely to see higher rates of recycling when their underlying demographic and attitudinal attributes reflected characteristics that have been associated with increased recycling activity. However, when program convenience was high (and fee structures less visible) high rates of recycling were found across cities with both favorable and unfavorable demographic characteristics. I use case-specific detailed narratives to explore the factors that influence outcomes among selected cities that did or did not meet my expectations.
