How community participation and stakeholder involvement can improve recycling : an investigation of initiatives and opportunities in Simunye

Myeni, Jabu R January 2013 (has links)
This report presents the findings of a research project whereby the initiatives and opportunities for municipal solid waste (MSW) recycling were investigated in the town of Simunye, in Swaziland with a view to establish how recycling, in particular household waste recycling, can be improved through stakeholder involvement and community participation during the planning and implementation of a sustainable system for household waste recycling in Simunye. The reason for focusing on household waste was because source separation of household waste was identified as a potential area for improving efficiencies and cutting costs by the local authority. It was deemed necessary to conduct research because there was a history of failure in respect of household recycling. In 2006 an initiative, by the local authority, for separating household waste at source had ended up in failure. The participation rates of the households turned out to be very low even though they had been issued, free of charge, some plastic bags for sorting the waste. Some of the households were found using the bags for other purposes rather than recycling. As a result, the initiative had to be suspended (White, 2010). There is a new move to revive the project in order to cut costs and minimize wastages. This time around the local authority is determined for the new project to be a success story. Since the underlying causes for the failure of the previous initiative were never investigated formally (Khumalo, 2010), the starting point would be to identify and try to eliminate all the potential barriers to recycling through a consultative process to start with.

Waste services provided by community-based enterprises in the Ngombe Peri-Urban settlement area, Lusaka, Zambia

Maninga, Mainess Kapaipi January 2012 (has links)
This qualitative study investigates Waste services provided by community-based enterprises in the Ngombe peri-urban settlement area - Lusaka, Zambia. The aim of the study was to identify and analyze the factors that contribute to illegal dumping of solid waste in the said peri-urban settlement area. The research objectives were as follows: To explore the capability of the community-based enterprises to effectively manage their enterprises in relation to the provision of solid waste services to the residents of the said settlement, To identify and evaluate the solid waste services provided by the community-based enterprises, and To make recommendations for the improvement of solid waste service provision and utilisation based on the findings of the study. The method of data collection for the above listed objectives was a literature study and focus group interviews. In order to achieve the said objectives of the study, the researcher opted for a qualitative research design – utilizing the contextual, descriptive, inductive and deductive approaches. The research population comprised the community-based enterprises involved in the provision of solid waste services in the Ngombe settlement area namely Kutwano and Tiyende Pamodzi Waste Enterprises. The purposive sample method was used for the selection of the focus group. The focus group discussions were captured by means of an audiotape and note-taking. The interviews were transcribed verbatim, within 24 hours of data capturing. Data analysis followed the five steps of Powell and Renner (2003, pp,1-6), namely: familiarization, identifying a thematic framework, categorization (coding or indexing) of data, identifying patterns and connections within and between categories (relationships), and interpretation (bringing it all together). The researcher adhered to the relevant ethical considerations and the principles of trustworthiness, namely: credibility, transferability, dependability and conformability throughout the study. In exploring the capability of the two community-based enterprises to effectively manage their enterprises in relation to the provision of solid waste services to the residents of the said settlement it was found that community-based enterprises do not have the capability to provide adequate solid waste services. This is due to inadequate leadership and entrepreneurship skills of the community-based enterprises management committee members, non-payment of solid waste collection fees by the majority of households and inadequate legal enforcement by the Lusaka City Council’s Waste Management Unit. In identifying and evaluating the solid waste services provided by the community-based enterprises it was found that solid waste services provided by community-based enterprises were inadequate. This is due to the type of equipment (push carts) used for primary solid waste collection that does not carter for other forms of solid waste like construction waste; inappropriate solid waste storage containers (25kg maize meal bags) which do not allow storage of solid waste in a sanitary manner (non-leak proof, accessible to rats, flies and cockroaches and rodents); restriction on the type of solid waste that community-based enterprises should collect (in relation to the specified solid waste storage container, 25kg maize meal bags) and the delay of secondary solid waste collection by Lusaka City Council’s Waste Management Unit. On the basis of the findings of the study, a number of recommendations are being made, which, if implemented effectively, should improve the provision and utilisation of solid waste services within the study area. Such an improvement should lead to a higher level of environmental cleanliness, and ultimately to better health standards of the people living within the area.

Trans - form - medium: the transformation of light, space and process through the medium of glass, a glass recycling hub for Waste Reclaimers in Newtown

Hardman, Murray R. 27 May 2015 (has links)
This document is submitted in partial fulfillment for the degree: Master of Architecture [Professional] at the University of the Witwatersrand, Johannesburg, South Africa, in the year 2014. Supervised by Professor Diaan van der Westhuizen / High levels of unemployment are a reality in many of the urban areas of South Africa. Poverty and hardship compel many of the unemployed to venture into the urban informal economy in order to survive. The South African government have found new ways of creating employment opportunities, one of which is within the recycling industry. There is an increased demand for minimizing mankind’s environmental footprint. Glass is a material that has been used for centuries and has the ability to be recycled infinitely without losing its quality (Marson, n.d). This together with the need for glass amongst consumers and the endlessly recycling nature of glass makes glass recycling a significant sustainable measure in considering environmental impacts (2011, 2012 Annual Review: Glass Recycling Company). Despite these properties, glass continues to be an undervalued material that can utilize low technology in its recycling process. This study aimed at investigating the formal and informal recycling economy within the city of Johannesburg by providing the opportunity for the Waste Reclaimers (Trolley Pushers) to be an integral part of the recycling process, specifically with glass. A further aim was to explore the tectonics of a factory to create a space where the Waste Reclaimers could gather, connect and engage with the product of glass. Lastly it aimed to provide a space where the general public could also engage in the product of glass recycling thereby creating awareness and promotion of recycling. The project proposed a glass recycling factory where the process of glass recycling culminates with the production of glass. The site selected for this research is located within the industrial part of the Newtown precinct. This has become a central recycling hub for the Waste Reclaimers of Johannesburg as it links private recycling centres within the city. Newtown is an area of flux, marked by a history of industrial and political disruption. This area represents change and opportunity for growth and life. A space recycled and regenerated throughout the history of Johannesburg. The reason for the choice of topic is that the evolution of recycling in Johannesburg has reached a point where municipalities need to acknowledge the informal sector as a valuable part of the recycling economy. The majority of the literature on recycling and the organization of the recycling process predominantly focuses on the collection of waste as means of job creation. An opportunity therefore presented itself to highlight the production, and craftsmanship of recyclable material. To clarify and further place the Waste Reclaimers within the existing waste management system, the theory of Phenomenology has been explored. It will focus on the phenomenological term of “Lifeworld” which describes a way of life where the individual’s aspiration, perceptions, experiences, beliefs and behaviour forms a holistic unity towards a fulfilling, meaningful, existence (Seamon, 2012). This exploration will give insight to how this building will provide the Waste Reclaimer a sense of identification and orientation within this system of the recycling industry. In order to better understand the complexity of the existing waste management system, the theory of Systems has been explored focusing on the principal of an open system as a way of broadening the lifeworld of the Waste Reclaimers Precedent studies of PFG Building Glass windscreen recovery facility; Zama City Waste; the comparison of factory tectonics between the Crystal Palace, Toledo Museum of Art Glass and the Crucible Glassblowing studio; the Glass Chapel and The Nelson-Atkins Museum of Art were used to inform the design. The network of the Waste Reclaimers was also documented in order to understand their routes and network across the city and the surrounding suburbs. The impact of the design found that the proposed space created opportunities for pause and transformation using light, space and process. The idea of transformation is process. Process is represented by a linear path with adjacent spaces of function and support. These spaces will transform according to their activities and associated light qualities. These spaces will thus become the medium through which people and activities change.

Curbside collection of recyclable materials: fifteen cases studies in the United States

Waterman, Donna Ruth 01 August 2012 (has links)
Fifteen curbside recycling programs in the United States, from communities representing a variety of economic, geographic and political situations, were reviewed in this study. Case studies were analyzed and discussed with respect to four areas of interest to program planners: administration, operations, promotion and evaluation. No objective rating of the programs was attempted, but approaches were reviewed with respect to their ability to satisfy the goals of the programs. Comparisons of participation rates, waste diversion rates, and costs were used cautiously because of the inconsistencies in how the data were developed from program to program. Administrative approaches found in the case studies included: (a) complete ownership of the collection and processing system by municipalities; (b) contracted service by private waste management firms; (c) contracted or subsidized service by non-profit organizations; and (d) combinations of municipal, private, and non-profit services. Operational systems were examined with respect to the effectiveness of the service in stimulating participation, given the practical, political, and budgetary constraints. Variables of operation are closely related and include: (a) which materials are collected; (b) the degree of materials separation required; (c) the type of collection vehicle(s) used; (d) collection frequency and coincidence with garbage collection; (e) the provision of in home containers; and (t) the extent of post-collection materials processing. Four categories of promotional techniques used in curbside recycling programs were discussed: (a) publicity and education; (b) personal contact; (c) economic incentives; and (d) ordinances mandating source-separation. The impacts of these techniques on participation in the case study programs were discussed. Techniques for evaluating the efficacy of curbside recycling programs were also discussed. Participation rates, waste diversion rates, and cost were reviewed with respect to current usage and recommendations were made for increasing their usefulness as indicators of the success of programs or program elements. / Master of Science

Urban waste picking in low-income countries: knowledge and action

Gauley, Steven W. 05 1900 (has links)
A significant segment of the urban population in many low-income countries derives their living from the harvest of marketable materials from urban waste streams. The activities of so-called "scavengers" or waste pickers in many African, Asian, and Latin American cities have also come to be understood to have environmental benefits: the diversion of materials from the urban waste stream decreases the volume of wastes that need to be collected, transported and disposed of. However, due to their daily contact with garbage, these men, women, and children are usually associated with dirt, disease, and squalor. The work of the scavenger is often conceptualized as being poverty driven and undertaken as a survival strategy or coping mechanism in a harsh urban environment. In recent years, various programs and projects have been developed by nongovernmental organizations, religious institutions, community-based organizations, and local governments to address the needs of scavengers. Such intervention schemes are designed in one way or another to alter the scavengers' existing situations. This study looks at the possible linkages between the evolving understanding of scavenging and the various approaches to intervention that it engenders. This study first examines how scholars and researchers analyze waste picking issues and their suggestions for potential interventions and then relates this understanding to how institutions, citizens, non-governmental organizations, and aid agencies are addressing these issues in practice. It is found that different conceptualizations of waste picking issues have led to different intervention prescriptions, and that the prescribed interventions are motivated by environmental, economic, or humanitarian concerns. This study contends that the recommended and implemented intervention prescriptions are simply promoting market means in an attempt to achieve humanitarian ends, and, therefore, are only short-term measures that will not solve the identified waste picking issues. Data sources used in this effort include academic journals, conference papers, case studies of development programs, newspaper articles, Web sites, and field reports. Data were also obtained by contacting researchers and organizations that have studied or are currently working with waste pickers in a variety of geographical settings.
