The regulation of domestic solid waste management in local government : perspectives from the Limpopo Province / Maria Marupeng Malatji

Malatji, Maria Marupeng January 2014 (has links)
In general, the improper disposal of waste may hinder the constitutional guarantee of a right to an environment to human health or well-being. This is especially true of domestic solid waste, a particular area of the waste stream frequently disposed of on South Africa's vacant land, rivers and streets amongst other. There is need therefore for municipalities as locally based authorities that are constitutionally bestowed with specific functions and duties in relation to waste, to ensure effective domestic solid waste management. The aim of this study is to investigate the content and design of some legal instruments aimed at domestic solid waste management in two municipalities of South Africa’s Limpopo Province namely the Lephalale and Greater Tzaneen Municipalities. The investigation and critical analysis of the selected instruments are based on the content of South Africa’s national waste law and policy with respect to domestic solid waste management specifically. The study concludes with a number of observations and recommendations with respect to the investigation instrumentation of Lephalale and Greater Tzaneen Municipalities. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2014

Waste recycling and small, micro, and medium enterprises (SMMEs) development in Greater Kokstad Municipality.

Sobuce, Ndabazovuyo Wellington 15 February 2013 (has links)
Waste management is a global phenomenon and all nations need to ensure that waste is handled in an environmentally friendly and healthy manner. Municipalities in South Africa generate a lot of solid waste which is disposed of in the landfill site. The life span of these landfill sites is shortened by all waste that gets disposed on site. The only mechanism that can be used to minimize the amount of waste disposed of in the landfill site is waste recycling. At Greater Kokstad Municipality (GKM) there are very few companies that are involved in recycling activities. The rate of unemployment in the area is high and recycling activities would provide employment opportunities. This study is based in Kokstad and emanates from the fact that there are large volumes of waste discharged at the Kokstad landfill site. It seeks to explore the experiences and challenges faced by waste pickers and recycling SMMEs in the GKM. Also to identify reasons that causes waste pickers and SMMEs not to use the opportunity created by large volumes of unused waste to establish self-employment or employment of large numbers of unemployed people. This study used a qualitative research method and a phenomenological research design. The researcher used focus groups and semi-structured one-to-one interviews based on question themes or an interview guide. Data gathered was analyzed using Tesch’s method of data analysis and thematic content analysis. The main findings of the study revealed vital information that can assist in shaping and planning recycling activities within Greater Kokstad Municipality. Findings also highlight the need to create an environment conducive to the implementation of effective recycling initiatives.

Mudanças no atual papel do catador de materiais recicláveis na cadeia de gestão integrada de resíduos, em face das políticas públicas para o setor em um estudo de caso / Changes in current waste picker´s role in the integrated waste management chain, facing the public Brazilian policy for this sector in a case study

Santos, Leandro Dobre Baptista dos 28 November 2011 (has links)
No Brasil, a gestão e destinação de resíduos sólidos são problemáticas e podem ter grandes melhoras com o cumprimento das diretrizes da Política Nacional de Resíduos Sólidos (PNRS). Esta Política aponta para os princípios da Gestão Integrada de Resíduos (GIR), que indica diversificação no tratamento e disposição final como última alternativa. Uma ferramenta importante na GIR é a reciclagem, que no Brasil se estruturou com base no trabalho do catador, fragilizado na Cadeia Produtiva de reciclagem, não possuindo profissionalização equiparada com os outros membros. Verificada a situação de responsabilidade delegada aos catadores no futuro da Gestão de Resíduos sólidos e sua condição atual, no contexto de uma associação de catadores, constatou-se que os agentes se consideram em posição desigual dentro da Cadeia, e apresentam a necessidade de melhorar a comercialização e percebe-se esta Cadeia de Reciclagem comprometida neste ponto. Isto se verificou porque a estrutura da associação era limitada em vários aspectos. A PNRS atribui grande importância aos catadores, que aqui não dariam conta de coletar os resíduos, isto pela necessária melhora da gestão. Há também o fato de que alguns materiais não são de interesse do catador, considerados inviáveis. A reciclagem de certos materiais não ocorrerá naturalmente, sendo necessário algum tipo de intervenção. / In Brazil, management and solid waste disposal are problematic and can have major improvements to compliance with the guidelines of the Brazilian National Policy (PNRS), that points to the principles of the Integrated Waste Management (GIR), which indicates waste treatment and disposal diversification and final disposal as the last alternative. An important tool in the GIR is recycling, which in Brazil is structured based on the work of the waste picker, weakened actor within the Recycling Production Chain, which has no professional capability as the other members. Verifying the situation regarding the responsible delegated to the waste pickers in the future of the solid waste management, and its current condition, in a waste pickers association, It was found that the collectors consider themselves in an unequal position within the chain, and have need of commercial relations improvement. Upon the lack of equivalent professionalism of the waste picker with the other levels, it is clear that the recycling chain is committed at this point. This occurred because the structure of the association was limited in several respects. The PNRS assigns great importance to the collector, that here were not going to collect all the waste, because there is necessary improved in management. There is also the fact that there are some materials that they do not work for its non-viability. It was found that the recycling of certain materials will not occur naturally, requiring some type of intervention.

Gypsum Wallboard: A Study Examining Wallboard Waste Management Options for Southern Ontario

van de Merwe, Susan January 2009 (has links)
In 2005, the Recycling Council of Ontario published a report that identified the construction industry as one sector that did not manage its waste in an environmentally appropriate manner. In this report, Let’s Climb Another Molehill, 15 case studies were executed to understand why this industry was neither handling nor disposing its waste properly in Southern Ontario. A set of generic recommendations was generated to help improve the management of this industry’s waste. Unfortunately the scope of the report was too broad to support conclusions about the management of specific types of problematic construction waste. The aim of this thesis is to narrow what was done in Let’s Climb Another Molehill to focus only on gypsum wallboard. The purpose of this research is to determine what options are the most desirable and feasible to deal sustainably with gypsum wallboard waste in Southern Ontario, both now and in the future. All recommendations offered are case specific. A number of methods have been utilized to obtain the information needed to formulate appropriate recommendations to deal with wallboard. Information learned through the literature, witnessed through the observation sessions, and acquired through the interviews led to two unique option categories: 1) alternative materials and 2) change in practices. To evaluate these options, a set of criteria was created based on the concepts of sustainability and integrated waste management (IWM). This sustainable IWM criteria set allowed for consistent evaluation of the options. To improve the recommendations, the sustainable IWM criteria were refined to better deal with each of the two categories of options. When the sustainable IWM criteria for evaluating alternative materials were applied, gypsum wallboard was found still to be the best interior wall material to use today. However, applying the sustainable IWM criteria for evaluating change in practices showed that the problem with using this product lies with its management and, therefore, the remaining recommendations focus on improving the creation, use and disposal of wallboard. Many of these recommendations can easily be adopted to help eliminate inappropriate wallboard management practices. This research was able to identify areas where problems arose and to offer feasible options to improve environmentally inappropriate behaviors associated with wallboard management. Although numerous recommendations are offered, the three fundamental recommendations that will lead to the biggest change include: 1) greater number of educational programs devoted to the construction industry; 2) stricter regulations and better enforcement; and 3) a dramatic increase in landfill tipping fees. If these three recommendations were implemented, it is believed that they will play a positive role in managing gypsum wallboard waste in a more sustainable manner.

Opportunities and challenges of a Sustainable Solid Waste Management in Tsumeb, Namibia

Croset, Elliott January 2014 (has links)
The handling of wastes is an eternal problem, all societies are confronted to this issue. Their origins are very diverse, they could come from industrial activities, power production, shops, retail or household for instance. While in developed countries the collection is generally efficient and the disposal safe, the situation in developing countries is different. The municipal budget does not allow the construction of advanced and expensive methods of disposal and the collection suffer from the age of vehicles. This generalisation is nevertheless not totally truth as the situation is extremely depend on the country but also of the city considered. Each city will need to adapt its waste management according to its size, climate, wealth, culture, etc... This report will focus on a Namibian medium town, Tsumeb. The aim is to be able to draw a clear picture of the waste management currently achieved. When the situation is well known, new directions to make Tsumeb refuse management more sustainable can be decided. Implementing progressively an integrated waste management (IWM) is a solution to the waste problem as it is considering economic, social and environmental impacts. A waste characterization was done in order to know the exact amount and composition of the waste generated in Tsumeb to implement afterwards the most suitable solution. The refuse of Tsumeb are surprisingly very similar to high income country. Moreover the stakeholders involved in recycling were investigated. A small informal sector is already making a living by recycling a few materials as glass bottle and cans. There is also a possibility to include extra stakeholder in the recycling process in Tsumeb. Recycling companies, recycling organization or investors are also important stakeholder who can be include in Tsumeb recycling plan. Developing recycling in Tsumeb is facing some challenges but it is also full of opportunities. The main issue when it comes to recycling in Namibia is the long transportation distances what makes it expensive. Furthermore, most of the recovered materials have to be sent in South Africa because Namibia does not possess the necessary industries to recycle paper and glass for instance. On another hand the presence in Tsumeb of a small informal sector already working with waste is promising. The workers could be more organized and the municipality can also helping them with logistic and storage to improve the recycling done. The dump site will also be close within the next years and a new sanitary landfill will be open. It will be a great opportunity to implement a recycling facility on site. Informal workers working on the landfill will be more controlled, to avoid for instance children labour. Some stricter health and safety measure can be decided, to give better working condition to the informal manpower. The development of recycling activities in Tsumeb will be highly beneficial to the community. It will create jobs for the poorest part of the population, decrease the cost of the waste management, reduce the pollution and stimulate the local economy.
