Poverty in its many guises - poor housing, no employment, indifferent health and hunger is a driving force for scavenging. In most developing countries, the informal recovery of material from waste is a common survival strategy for the poor. In fact, up to 2% of populations in developing countries depend on recovering, re-using and selling waste materials from streets, dumpsite or landfills for their livelihood. The aim of this study was to develop an understanding of the socio-economic conditions affecting the scavengers and scavenging activities at the Hulene dumpsite in Maputo. This study set out to develop a conceptual framework depicting scavenging, its problems and opportunities. This was used to structure the research. The main issues addressed were: • The driving forces of scavenging where poverty is the major factor. • The organization of scavengers and scavenging activities showing that there is no formal organization of scavengers, which leads to exploitation of vulnerable groups. • The reaction from the national and local authorities, with the prevalence of a repressive policy and absence of support. • The gender dimension on scavenging activities; and • The perception of health risks. The findings are that scavenging constitutes a means of livelihood for poor people. These activities respond to the market demand and not to environmental considerations. However, in performing scavenging activities which results in informal recycling and resources recovery, people generate environmental benefits, economic benefits and social benefits. Other findings are that the informal organization of scavengers increases the exploitation and the health risk of scavengers. Thus, organization is a key to the success of scavengers and indirectly to the municipal economy. It is concluded that the framework set out in this thesis is useful in the sense that it illustrates the factors which influence scavenging activities. This framework can be used for further research in similar situations. It is also concluded that prohibition of scavenging activities would have undesirable consequences for the economy of Maputo in particular and of Mozambique in general. Thus, since this activity brings benefits to scavengers and to society, the government should support and stimulate this activity and not persecute those who provide this service. Consequently, as a recommendation, government, local communities and NGOs are called upon to support scavengers. The formation of scavenger co-operatives can promote sustainable grassroots development in this sector of the population. / Thesis (M.Env.Dev.)-Unversity of Natal, Pietermaritzburg, 2001.

Municipal solid waste management is gradually becoming a major challenge that is confronting governments in all spheres. This can be attributed to urbanisation and startling population escalation. Each and every member in a community is a contributor to this dilemma and a generator of waste. The essence of this study is to investigate whether the utilisation of education programmes can assist to improve how communities handle and dispose their household waste and its contribution to the effectiveness of the integrated solid waste management system for the New Brighton Township in the Nelson Mandela Bay Municipality. A theoretical framework is developed using the systems theory in trying to address the challenge. The study used the qualitative research method. Data were gathered using questionnaires and face-to face interviews. The empirical survey was employed for the purposes of the study and the interpretation of the research findings were analysed and described. As a metropolitan municipality, it is envisaged that this research will assist the NMBM, to identify how to manage solid waste efficiently and effectively and thus enhancing service delivery that will ensure communities of their well-being and dignity. Various recommendations are presented, based on the findings of the study. It is hoped that these recommendations If are adopted, the NMBM will be able to deal more effectively and efficiently with the challenges that the NMBM is faced with in dealing with waste management issues thereby enabling the NMBM to deliver the most basic need to the communities of the New Brighton Townships.

The Second-Hand Society tells the stories of people in Portland, Oregon who redefine waste by making use of objects others discard. The author spends time in repair shops watching craftsmen hammer and polish broken typewriters, vacuum cleaners and shoes back to life. She follows book scouts, clothes pickers and liquidators as they gather merchandise to resell and spends hours at nonprofits that collect and redistribute unwanted electronics and building supplies. She watches junk artists and fashion designers assemble found objects into display pieces, accompanies Dumpster divers and "freegans" along their regular collection routes and visits the homeless encampment by the airport to see how an entire community of people survives on nothing but reclaimed materials. The members of the second-hand society challenge the traditional conception of things as "broken" or "unwanted" and assert that forward movement and new-new-new is not always optimal. By examining the motivations and practices of the people who make use of our discards and looking at the contradictions they run up against, this thesis develops a more complete understanding of the reality that's possible if we think differently about our waste.

MENVSC / Department of Ecology and Resource Management / Solid waste management (SWM) has become an issue of increasing worldwide concern as urban populations continue to rise and consumption patterns change. The health and environmental effects associated with SWM are escalating, predominantly in the perspective of developing countries. The rise in rural-urban migration rates in developing countries has left local authorities overwhelmed and failing to cope with the increase in solid waste. This has led to a shift from conventional systems of solid waste management to contemporary systems such as community based solid waste management (CBSWM). Despite the shift, it seems local authorities in developing countries still fail to manage suburban waste effectively. This study investigated the performance of a CBSWM scheme in Nkulumane, a high-density suburb in Bulawayo. Both quantitative and qualitative data were collected, hence a mixed methods approach employed. The study incorporated systematic sampling and purposive sampling in the selection of research participants. Data was collected through qualitative questionnaires, semi structured interviews and field observations. Thematic content analysis and descriptive statistics from SPSS version 25 were used in data analysis. The study revealed that community members from Nkulumane had sound knowledge on what CBSWM entails, however the community members had negative attitude towards CBSWM and traditional notions on SWM had an influence of their perception of CBSWM concepts. The study also revealed that Bulawayo City Council had managed to create employment for the community through a CBSWM scheme. Furthermore, operating expenses of the city council had decreased over the years. The level of environmental awareness had improved in the study area as well. However, Bulawayo City Council has battled with community participation problems, financial constraints and inter-institutional infighting. This study provides a comprehensive report on the performance of the CBSWM scheme in Nkulumane high density suburb, Bulawayo, Zimbabwe. / NRF

Waste management is a global concern and landfill sites are facing a crisis of handling capacity. This is worsened by the fact that many consider landfilling as an environmentally responsible and cost-effective solution to waste disposal. Carnival City generates vast quantities of solid waste on a daily basis and most of it ends at the landfill, which it acknowledges that it’s a wastage of recoverable resources, hence its commitment of “zero-waste-to-landfills by 2022”. This study evaluated solid waste management practices at Carnival City Casino in Brakpan. Informed by an interpretive paradigm, qualitative methods including interviews, observations, photographs and document reviews were used to collect data. Based on abductive reasoning, the waste management hierarchy and the ISO 14001 standard were used as frameworks for recontextualising and presenting the collected data. The waste hierarchy sets out the preferred order of waste management practices, from the most favoured to the least preferred option. The effectiveness of current waste management practices is limited as Carnival City heavily depends on landfilling and implement waste minimisation, reuse, recycling and recovery on a small scale. Absence of a waste separation at source policy limits recycling activities significantly. The researcher noted the presence of some areas of conformity to South African legislation pertaining to waste management, international standards and Carnival City’s standard operating procedures, and some areas of good practice. The study showed that there is room for improving concerning Carnival City’s current waste management practices. It recommends that waste management training and awareness be undertaken on a continuous basis to improve current practices and ensure that more waste is diverted from landfill sites. Investment into waste to energy technologies should be considered to help Carnival City to meet Sun International’s commitment of “zero-waste-to-landfills by 2022”. Recycling must be maximised and its environmental and financial benefits be highlighted. The research recommends developing of a separation at source policy and its enforcement by the Environmental Committee as the absence of the documented procedures results in deviations from environmental objectives. Offenders who do not follow procedures should be duly punished. It also recommends that a disciplinary action and a fine be introduced for kitchens that will deviate from the policy. / Environmental Sciences / M. Sc. (Environmental Management)

The research work critically analyzed the factors responsible for imprudent waste tyre management in South Africa. As an approach to determine the complexity of the problem, questionnaires were sent to one hundred and sixty (160) respondents in conjunction with interviews. Perusal of literature and interaction with industry involved in waste tyre processing to further gain knowledge of the problem and possible solutions that can be solicited to address the problem. Findings revealed that, lack of clear, focused legislation that guide the handling, disposal and processing of waste tyres remain the challenge. It is also deduced that recycling of waste tyres can provide economic benefits and opportunities. It is recommended that South Africa develop appropriate legislation that deals with handling, treatment and disposal of waste tyres, develop an incentive programme to set up initiatives as well as developing skilled and capacitated enforcement agency. / Environmental Sciences / M.A. (Environmental Management)

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)

Submitted in fulfillment of the requirements for the Degree of Master of Technology Degree : Environmental Health, Durban University of Technology, Durban, South Africa, 2015. / Introduction Informal waste picking has both economic and environmental benefits, however there are many health risks associated with this activity. This cross sectional descriptive study assessed the respiratory health risks and dust (PM2.5) exposure among informal waste pickers operating at the New England landfill site in the Msunduzi Municipality. Data was collected from 102 informal waste pickers using a validated questionnaire adapted from the British Medical Research Council and American Thoracic Society. Our study population comprised of 66.4°/o women with a mean age of 36.7 years. Women reported greater use of safety shoes and gloves compared to men. Very few participants used dust masks or respirators. Results showed a high prevalence of chronic cough (57o/o), wheeze (51°/o) shortness of breath (31.6°/o) and cough with phlegm (29.0°/o) among all participants. Among those who reported having ever smoked, there was a significantly higher prevalence of cough with phlegm (45.2°/o p=0.02) and wheeze (73.1°/o, p= 0.05). Similarly, there was a bivariate association between current smoking and wheeze (p=0.02) and between ever smoked and wheeze {p< 0.05). A random sample of 28 waste pickers was chosen from the 102 participants for personal sampling. The levels and distribution of time weighted average to PM2.5 were calculated during an 8 hour working period. Average personal sampling levels of PM2.5 were very high compared to environmental levels. Personal sampling results showed a maximum exposure of 431 J.,Jg/m 3 and a mean of 187.4 J.,Jg/m 3 compared to a maximum level of 27.9 J.,Jg/m 3 and a mean of 16.5 J.,Jg/m 3 for environmental sampling. Mean personal sampling results significantly exceeded recommended eight hour time weighted average for South African National Standard for Occupational Exposure Limit (Republic of South Africa OHS ACT 85 of 1993), World Health Organisation and United State Environmental Protection Agency guidelines for PM2.5, while the environmental mean was within guidelines. This study showed that waste pickers are exposed to high levels of PM2.5 while working at the landfill site. Limited or no use of personal protective equipment increases risk of dust exposure and adverse respiratory effects. The relatively high prevalence of cough, shortness of breath and wheeze symptoms among these informal waste pickers may be linked to exposure to dust at the landfill site / PDF copy unavailable. please refer to hard copy for full text information / M
