A systems approach to community engaged integrated solid waste management in Todos Santos Cuchumatan, GuatemalaMarshall, Rachael 11 January 2013 (has links)
Solid waste management (SWM) is a growing problem in developing countries around the world. In Guatemala, indigenous communities, which are predominantly rural and remote, are particularly hard hit by a lack of basic SWM services. Todos Santos, situated in the Cuchumatanes mountain range of northwestern Guatemala, is one such community. As projects developed, planned, and implemented from 'the top down' continue to be ineffective, the literature provides little insight about remote communities' perspectives on exactly what issues SWM creates, influences, and exacerbates, and how they might respond to these concerns themselves. Using a participatory systems approach, this study investigated the systemic structures and behaviours that maintain and exacerbate SWM challenges in Todos Santos, and where key places (leverage points) to intervene in the system may exist. The study presents a wide selection of locally appropriate SWM solutions to target these leverage points in the form of four future scenarios These scenarios act as a step-wise implementation plan for gradual implementation in the community, each building upon the previous, ultimately reaching a community-defined vision for SWM.

Corporate Recycling Behavior Through the Lens of Situational Factors : Case study at Tarkett AB in RonnebyRemle, Christian, Bertilsson, Carl-Philip January 2018 (has links)
Introduction: The unsustainable recycling patterns of various companies in Sweden lead to a waste of possible resources. These resources can create value through re-production in circular processes. The issue that this study address is the recycling behavior among workplaces. There is a gap in the research of understanding influences to recycling behaviors among industrial companies, which is the target in this study. Theory & Purpose: This thesis employs behavioral theories on recycling activity through a framework developed by the authors with the aim of determining factors that affect the present recycling behavior within industries. Therefore, the purpose will be to investigate recycling behavior of companies within the flooring industry in Sweden. Furthermore, its purpose is to broaden the knowledge about recycling among companies and what situational factors that affect recycling behavior. Methodology: For data gathering, the thesis followed a quantitative method through conducting an online survey. The survey was sent out to 190 companies, and this resulted in 55 respondents which is a response rate of 28.9%. The survey data were collected to evaluate the prediction of behavior by the use of statistical regression analyses in STATA. Ordinal and binary data were the primary data types collected and used. Analysis & Results: A Probit regression model tested the survey data followed by calculations of the marginal effects. Marginal effect is used to conclude how much each situational factor provoked the probability of RECYCLING BEHAVIOR when the other factors are unchanged. The analysis made the support that RECYCLING BEHAVIOR is significantly related to the factors INFRASTRUCTURE, CONVENIENCE and ORGANIZATION COMMITMENT. Furthermore, there is an existence of latent factors affecting recycling behavior. This existence is because the statistical model partly explains the connection. Alternative factors should be investigated in further research since there are limited studies done on the topic. Conclusions: Considered benefits are for; the flooring industry as well as other industries and society at large. The understanding of enablers for influencing RECYCLING BEHAVIOR is one of the benefits of this study. Changes in arrangement and mobility of recycling stations, together with an increase of social norms and recycling policies, suggests being practical goals. Moreover, communicating these standpoints are important for companies to gain value. Nonetheless, protecting the environmental boundaries by decreasing the use of raw material in a growing global production market. Understanding how situational factors affect RECYCLING BEHAVIOR will help actors move towards more sustainable and circular acts. Regarding recycling among industries, this study can be used to understand how to gain more value in existing circular economy systems as well as waste management systems. Both economic value and ecological value can be determined, from putting waste material into new products instead of incinerating it. Future Research: Directions for future research include qualitative case studies, experimental testing, and models including internal factors, attitude, habits and subjective norms. Extending this thesis with other approaches will benefit to find further correlations and predictions regarding recycling behavior among companies. Further research should also include economic aspects of the material gained through recycling behavior.

Waste Management Systems in Lebanon : The benefits of a waste crisis for improvement of practicesAzzi, Elias January 2017 (has links)
Municipal solid waste management is a public service which, when it fails, can rapidly become overwhelming for communities and authorities. It is also during the deepest crisis that incentives change and new practices emerge. Lebanon went through an 8-months waste crisis after the closure of the country’s main landfill. Facing the incapacity of restoring basic services, the monopolistic centralised system was questioned: civil society, social businesses and municipalities organised, at a smaller scale, their own waste management. The thesis aims were to identify the role of the new waste stakeholders in the broader picture, assess the efficiency and needs of municipal projects and suggest some priorities for the country’s solid waste policies. The use of process-flow diagrams and a contextualised classification of actors were used to describe the Lebanese system. Case studies of recent initiatives were made using an adapted ISWM framework. The investigations have shown that, since the crisis, waste management is organised around three complementary systems, with their own legitimacy, supporters and challenges, but overall lacking of cooperation and mutual recognition. The nascent decentralised waste management tends to achieve better than the traditional central system, especially in terms of landfill space saved, resource management and inclusivity of users. However, it faces issues when tackling final disposal, energy recovery and financing. Any future waste policy should include all waste actors, set clear targets and reject any “one-size-fits-all” solution benefiting private corrupted interests. / Hushållsavfallshantering är ett offentligt verktyg som, när det misslyckas, snabbt kan bli överväldigande för samhällen och myndigheter att hantera. Det är också under de djupaste kriserna som incitament förändras och nya metoder utvecklas. Libanon gick igenom en avfallskris som varade i 8 månader, efter stängningen av landets största deponi. På grund av oförmågan att återställa grundläggande tjänster, blev det monopolistiska centraliserade systemet ifrågasatt: det civila samhället, sociala företag och kommuner organiserade, i mindre skala, sina egen avfallshantering. Examensarbetets mål var att identifiera vilken roll nya intressenter av avfallshantering får i ett brett perspektiv, bedöma effektiviteten och behovet av kommunala projekt samt föreslå prioriteringar för landets politik gällande fast avfall. Ett processflödesschema och en kontextberoende klassificering av aktörer användes för att beskriva det libanesiska systemet. En fallstudie gjordes med hjälp av ett ramverk för integrerad avfallshantering över de senaste initiativen som tagits på området. Undersökningarna har visat att avfallshanteringen är organiserad kring tre kompletterande system, som har de egna rättigheterna, anhängare och utmaningar, men det saknas tydligt samarbete och ömsesidigt erkännande. Den nya decentraliserade avfallshanteringen tenderar att uppnå bättre resultat än det traditionella centrala systemet gjort. Det gäller särskilt när deponiutrymme kan sparas, resurshantering förbättras och användarna integreras i processen. Dock kvarstår problem när det kommer till att hantera slutförvaring, energiåtervinning, och även finansiering. Framtida avfallspolitik bör inkludera alla avfallsaktörer, fastställa klara mål och avvisa alla "one-size-fits-all" lösningar som gynnar privata intressen.

Characterisation and management of non-formal solid waste management disposal sites in Harare, ZimbabweMahamba, Caston 02 1900 (has links)
Text in English / The study focused on the characterisation and management of non-formal solid waste disposal sites in Harare, the capital city of the Republic of Zimbabwe. In many developing countries, increasing urbanisation surpasses the development of urban infrastructure and this has led to the proliferation of informal settlements, illegal dumping sites and uncontrolled vending in cities like Harare. The researcher investigated the prevalence of non-formal dumping sites in Harare, including the composition, locational attributes and internal linkages of solid waste. Practices regarding the management of non-formal solid waste disposal sites were examined and areas of good practice and conformity to international standards were complemented while recommendations and suggestions were made on areas that were found wanting. An integrated management system was recommended for the sustainable management of solid waste. To support this recommendation, management window of responsibilities (EMWR) model was created so that the Harare City Council can enhance stakeholder participation. The research results show that most residents used non-conventional ways to store waste, like mealie-meal bags and sacks, and this posed a danger to human health. It also emerged that the city of Harare has not updated some of its by-laws, some of which were enacted about 33 years ago while others remained drafts for decades. This made it difficult for the city to effectively implement them. / Environmental Sciences / M.Sc. (Environmental Management)
