A Case Study of a Hotel Solid Waste Management Program in Bali, Indonesia

Tang, Janeen January 2004 (has links)
The main objectives of this study were: to provide a review of key concepts and issues relevant to solid waste management in developing countries; to analyse and evaluate the hotel solid waste management (HSWM) program in Bali, Indonesia; and to suggest recommendations and areas for further research. The following data collection methods were used in this study: review of documents and literature, interviews, surveys and field observations. Tourism in host regions such as Bali can bring both positive and negative impacts. One aspect of tourism that can have an impact on local communities is solid waste management (SWM). Improper SWM can lead to pollution and deterioration of the aesthetic appeal of tourist destinations. Conversely, solid waste can be a resource to the local community, providing opportunities for business development and the achievement of social, political and environmental objectives. Planning for SWM is complex, involving the consideration of multiple and interconnected issues. Therefore, in addressing SWM issues, it is appropriate to use an integrated approach that recognises the various stakeholders, activities and perspectives involved. In addition, concepts such as appropriate technology, cleaner production, life cycle assessment and environmental management systems can be useful for improving how solid waste management is approached. A local environmental non-governmental organisation (NGO), waste hauler and hotels in Bali developed a program to improve the management of solid waste from hotels. The history, planning, management and stakeholders involved with the development of this program are described in this study. Various issues pertaining to the achievement of social, environmental and economic objectives are investigated to provide a view of program realities and the range of challenges faced by program participants. Conclusions and lessons learned from the case study are presented and links between concepts in the literature and findings from the case study are discussed. Recommendations concerning topics such as planning, management, stakeholder involvement, health and safety, data management and source separation are suggested and future research directions are outlined.

Producer responsibility for WEEE as a driver of ecodesign: Case studies of business responses to producer responsibility charges

Gottberg, Annika 11 1900 (has links)
Due to potential environmental, resource and health problems associated with waste, waste minimisation is a prioritised waste management strategy in many countries. Producer responsibility policies promote waste minimisation by stipulating separate collection and recycling of particular waste streams. In addition, a purpose of the policy is to encourage product development that reduces waste generation and improves recyclability. It is sometimes assumed that the financial responsibility assigned to producers for collection and recycling of their end-of-life products will instigate waste minimising product development in order to reduce costs. However, this view has also been contested. Following the adoption of the WEEE Directive (2002/96/EC) all EU member states have to implement producer responsibility for WEEE. Taking a qualitative multiple case study approach, this study explores company responses to the costs of existing national producer responsibility policies for WEEE in relation product development. The purpose is to inform policy-making on the effectiveness of producer responsibility charges in achieving waste minimising product development. The study comprises both large companies and SMEs in the lighting equipments sector. It also includes companies in EU member states without producer responsibility for WEEE in order to see if there are any differences in waste-minimising product design among countries and if national policies have an impact beyond national borders. Economic principles and previous research findings on ecodesign make up the analytical framework for the study. Quantitative data on cost-benefits of ecodesign and waste minimisation achievements were scarce. However, the company responses show that the costs imposed on the producers by the WEEE policy have had little effect on product development so far. The costs can generally be transferred to customers via product prices. The price increases were generally small and without any negative effects on competitiveness. Other drivers such as bans on certain substances, environmental industry product declarations, commercial advantages including direct customer demands from for instance public procurers, are more effective.

Facilitating opportunities for social learning about sustainable waste management

Kamaruddin, Siti Mazwin January 2012 (has links)
This study contributes to filling a gap identified in the current Malaysian national waste policy, the National Strategic Plan for Solid Waste Management (NSPSWM 2005). It also contributes to the sparse knowledge of NGOs’ involvement in Malaysia in promoting recycling and general environmental awareness with the Malaysian public particularly in an urban context. Although the NSPSWM alludes to NGOs as actors that can assist in improving the public’s awareness of and participation in sustainable waste management (SWM), there is sparse knowledge on how this is facilitated. This study was also motivated to investigate to what extent social learning elements were being embodied in the initiatives of two NGOs that were studied, as it is posited that facilitations for social learning create pathways for change. Although there are various studies on the functions of NGOs, there is little research conducted on how environmental NGOs play a part in SWM in Malaysia. The research approach applied in this thesis was mixed-methods, and the rationale was to apply both qualitative and quantitative methods that would be useful and would combine complementary strengths to help answer the research questions. A qualitative two-case-study approach was used to predict similar or contrasting results based on the theoretical framework considered relevant. The unit of analysis of each case study was a programme that promoted recycling as a sustainable waste management strategy, to the general public in the study area of Selangor, Malaysia. The first case study’s target audience was urban school students; while the second case study’s focus was urban school students, charity homes for the handicapped and hypermarkets. Both NGOs are considered two of the earliest NGOs in the study area to be involved in promoting SWM with the public. The quantitative aspects included findings from a questionnaire survey of 411 students. The population sampled was obtained based on a stratified sampling procedure. The urban student population’s response was collected to gain insights into students’ perception of NGOs’ involvement in SWM, and into what factors significantly influence the students’ recycling participation in schools. Both descriptive and inferential analyses were conducted. The findings from this approach complemented the qualitative findings obtained from the two case studies. In addition, interviews were conducted with some students to complement the survey evidence. Where relevant, secondary evidence from the press, reports and Web pages were used to support the primary evidence. The qualitative evidence was synthesized and the aggregated findings were then triangulated with the quantitative evidence for corroboration purposes. These evaluations revealed that the processes involved in the programmes to promote recycling supported social learning and positive outcomes. Almost half of the students sampled were aware and welcomed NGOs’ involvement in SWM, both in schools and in their community. They reported that they learned more about SWM and the environment from participating in their school’s SWM programmes (although these programmes may not necessarily have been facilitated by the particular environmental NGO identified in the case studies). The students also generally perceived that the government should support NGOs’ involvement in SWM and that SWM programmes in schools coordinated by NGOs were beneficial to their learning about SWM. Various factors were also found to have influenced their participation in sustainable waste behavior. The findings could be used to inform the relevant policy makers’ decisions about NGOs’ contributions towards SWM. In addition, the findings from the students’ survey could help inform other NGOs or other organisations, such as universities or corporate bodies that are interested in implementing SWM programmes with schools and who may be eager to extend their corporate social responsibilities using approaches similar to those highlighted in this thesis.

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
