DEPARTMENT or PROGRAM: Civil and Environmental Engineering -Signatures- Thesis Advisor: __________________________________________ Dr. James R. Mihelcic Department Chair: _________________________________________ Dr. Neil J. Hutzler Date: _________________________________________ ABSTRACT Sustainable management of solid waste is a global concern, as exemplified by the United Nations Millennium Development Goals (MDG) that 191 member states support. The seventh MDG indirectly advocates for municipal solid waste management (MSWM) by aiming to ensure environmental sustainability into countries’ policies and programs and reverse negative environmental impact. Proper MSWM will likely result in relieving poverty, reducing child mortality, improving maternal health, and preventing disease, which are MDG goals one, four, five, and six, respectively (UNMDG, 2005). Solid waste production is increasing worldwide as the global society strives to obtain a decent quality of life. Several means exist in which the amount of solid waste going to a landfill can be reduced, such as incineration with energy production, composting of organic wastes, and material recovery through recycling, which are all considered sustainable methods by which to manage MSW. In the developing world, composting is already a widely-accepted method to reduce waste fated for the landfill, and incineration for energy recovery can be a costly capital investment for most communities. Therefore, this research focuses on recycling as a solution to the municipal solid waste production problem while considering the three dimensions of sustainability environment, society, and economy. First, twenty-three developing country case studies were quantitatively and qualitatively examined for aspects of municipal solid waste management. The municipal solid waste (MSW) generation and recovery rates, as well as the composition were compiled and assessed. The average MSW generation rate was 0.77 kg/person/day, with recovery rates varying from 5 – 40%. The waste streams of nineteen of these case studies consisted of 0 – 70% recyclable material and 17 – 80% organic material. i All twenty-three case studies were analyzed qualitatively by identifying any barriers or incentives to recycling, which justified the creation of twelve factors influencing sustainable municipal solid waste management (MSWM) in developing countries. The presence of regulations, enforcement of laws, and use of incentive schemes constitutes the first factor, Government Policy. Cost of MSWM operations, the budget allocated to MSWM by local to national governments, as well as the stability and reliability of funds comprise the Government Finances factor influencing recycling in the third world. Many case studies indicated that understanding features of a waste stream such as the generation and recovery rates and composition is the first measure in determining proper management solutions, which forms the third factor Waste Characterization. The presence and efficiency of waste collection and segregation by scavengers, municipalities, or private contractors was commonly addressed by the case studies, which justified Waste Collection and Segregation as the fourth factor. Having knowledge of MSWM and an understanding of the linkages between human behavior, waste handling, and health/sanitation/environment comprise the Household Education factor. Individuals’ income influencing waste handling behavior (e.g., reuse, recycling, and illegal dumping), presence of waste collection/disposal fees, and willingness to pay by residents were seen as one of the biggest incentives to recycling, which justified them being combined into the Household Economics factor. The MSWM Administration factor was formed following several references to the presence and effectiveness of private and/or public management of waste through collection, recovery, and disposal influencing recycling activity. Although the MSWM Personnel Education factor was only recognized by six of the twenty-two case studies, the lack of trained laborers and skilled professionals in MSWM positions was a barrier to sustainable MSWM in every case but one. The presence and effectiveness of a comprehensive, integrative, long-term MSWM strategy was highly encouraged by every case study that addressed the tenth factor, MSWM Plan. ii Although seemingly a subset of private MSWM administration, the existence and profitability of market systems relying on recycled-material throughput, involvement of small businesses, middlemen, and large industries/exporters is deserving of the factor Local Recycled-Material Market. Availability and effective use of technology and/or human workforce and the safety considerations of each were recurrent barriers and incentives to recycling to warrant the Technological and Human Resources factor. The Land Availability factor takes into consideration land attributes such as terrain, ownership, and development which can often times dictate MSWM. Understanding the relationships among the twelve factors influencing recycling in developing countries, made apparent the collaborative nature required of sustainable MSWM. Factors requiring the greatest collaborative inputs include waste collection and segregation, MSWM plan, and local recycled-material market. Aligning each factor to the societal, environmental, and economic dimensions of sustainability revealed the motives behind the institutions contributing to each factor. A correlation between stakeholder involvement and sustainability existed, as supported by the fact that the only three factors driven by all three dimensions of sustainability were the same three that required the greatest collaboration with other factors. With increasing urbanization, advocating for improved health for all through the MDG, and changing consumption patterns resulting in increasing and more complex waste streams, the utilization of the collaboration web offered by this research is ever needed in the developing world. Through its use, the institutions associated with each of the twelve factors can achieve a better understanding of the collaboration necessary and beneficial for more sustainable MSWM. iii ACKNOWLEDGEMENTS First and foremost, I would like to extend gratitude to my advisor, Dr. Jim Mihelcic, for not only all of his support of this research, but for his contributions to my academic, professional, and personal development over the past six years.

  • The Greifswalder Theory of Strong Sustainability and Its Relevance for Policy Advice in Germany and the EU
    Sustainability Science – The Greifswalder Theory of Strong Sustainability and its relevance for policy advice in Germany and the EU Ralf Döring* , Barbara Muraca 1 *Johann Heinrich von Thünen - Federal Institute for Rural Areas, Forestry and Fisheries, Germany Abstract The Greifswald approach was developed over many years in the co-operation of environmental philosophers and ecological economists. The theory combines normative arguments on our responsibilities for current and future generations (intra- and intergenerational justice), the conceptual debate on weak vs. strong sustainability, a new concept for natural capital with practical applications in three sectors: fisheries, agriculture and climate change policy. It was developed as an answer to the increasingly vague understanding of the sustainability concept in the political arena, which gives politicians the possibility of subsuming under it all sorts of different programs and strategies. A sharper definition of the concept is needed that offers a non-arbitrary orientation ground for action to end the further loss of essential parts of natural capital without becoming too rigid and exclusive of differences. In this paper we give firstly a short overview about the philosophical background of the theory and about the conceptual debate on weak and strong sustainability. Secondly, we depict our concept of Natural Capital, which draws on Georgescu-Roegen’s systematic framework of fund, stock, services, and flows and focuses on a central characteristic of nature: its (re)productivity. Accordingly, natural capital consists of living funds, non-living funds, and stocks. This differentiation offers a helpful ground for identifying specific preservation goals for the different parts of natural capital and can be successfully employed in the advice for policy makers (as it has been the case with the German Advisory Council for the Environment over a decade).

Signature: Daw: Stellenbosch University http://scholar.sun.ac.za Ill ABSTRACT Municipal waste presents problems of pollution, health hazards and resource conservation. Household waste forms part of municipal solid waste that is a challenge to control due to its heterogeneity and diversity. The ever-filling landfills for the disposal of solid waste due to rapid population increase and urbanization call for urgent waste management strategies to reduce, reuse and recycle solid waste. In this study householders' attitudes, participation in recycling and willingness to participate in household solid waste recycling are investigated to design and implement a household solid waste recycling programme in Stellenbosch. Questionnaire survey data about the awareness of, attitudes towards, and participation in household waste recycling were analyzed using descriptive statistical methods in the STATISTICA V6 program. Results were displayed in frequency tables, bar charts, maps and pie charts. The same statistical program was used to fmd the relationship between the householders' willingness to participate in the household solid waste recycling programme, namely the Blue Bag Household Waste Recovery Programme (BBHWRP), and their socio-demographic and socio-economic characteristics.

  • The Sustainability of Waste Management Models in Circular Economies
    sustainability Article The Sustainability of Waste Management Models in Circular Economies Carmen Avilés-Palacios 1 and Ana Rodríguez-Olalla 2,* 1 Escuela Técnica Superior de Ingeniería de Montes, Forestal y del Medio Natural, Universidad Politécnica de Madrid, c/José Antonio Novais 10, 28040 Madrid, Spain; [email protected] 2 Departamento Economía de la Empresa (ADO), Economía Aplicada II y Fundamentos Análisis Económico, Universidad Rey Juan Carlos, Paseo de los Artilleros s/n, Vicálvaro, 28032 Madrid, Spain * Correspondence: [email protected]; Tel.: +34-910671632 Abstract: The circular economy (CE) is considered a key economic model to meet the challenge of sustainable development. Strenous efforts are focused on the transformation of waste into resources that can be reintroduced into the economic system through proper management. In this way, the linear and waste-producing value chain problems are solved, making them circular, and more sustainable solutions are proposed in those chains already benefiting from circular processes, so that waste generation and waste are reduced on the one hand, and on the other, the non-efficient consumption of resources decreases. In the face of this current tide, there is another option that proposes a certain nuance, based on the premise that, although circular systems promote sustainability, it does not mean that they are in themselves sustainable, given that, in the first place, the effects of CE on sustainable development are not fully known and, on the other hand, the CE model includes the flow of materials, with only scant consideration of the flow of non-material resources (water, soil and energy).

However, there is a limited understanding about where and how research about biosphere reserves’ management effectiveness has been conducted, what topics are investigated, and which are the main findings. This study addresses these gaps in the field, building on a systematic literature review of scientific papers. To this end, we investigated characteristics of publications, scope, status and location of biosphere reserves, research methods and management effectiveness. The results indicate that research is conceptually and methodologically diverse, but unevenly distributed. Three groups of papers associated with different goals of biosphere reserves were identified: capacity building, biodiversity conservation and sustainable development. In general, each group is associated with different methodological approaches and different regions of the world. The results indicate the importance of scale dynamics and trade-offs between goals, which are advanced as important leverage points for the success of biosphere reserves.
