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)

The aim of this study was to investigate the factors influencing household awareness and participation in domestic waste disposal and recycling, focusing on environmental educational (EE), wealth and location of suburb. The study was carried out in four suburbs in the Tshwane Metropolitan Area (TMA), namely Waterkloof, Lynnwood, Sunnyside and Mamelodi. A literature review was conducted, covering concepts of domestic waste management - waste prevention, collection, recycling and reuse, followed by household analysis using empirical data. The analysis shows that there is a low level of household awareness about the environmental implications of domestic waste management in TMA, and hence low level of participation in domestic waste sorting, disposal and recycling. Among relevant factors are the level of EE and income of the households across all suburbs. This calls attention to the need for strengthening EE not only in schools, but also in suburbs using both formal and informal outreach programmes. / Educational Studies / M. Ed.

Participatory Action Research (PAR) was carried out to improve educational practices and environmental sustainability in an International School in Vietnam by undertaking two cycles of PAR to determine how the school community could use paper on a more sustainable basis. The methodology included sorting paper and encouraging the reuse of paper. Practices related to computer printing, report writing and newsletter production were also investigated. Changes in the school community, in terms of accepting responsibility and demonstrating changed attitudes and behaviours, were measured. The school community demonstrated greater awareness, increased responsibility and more action competence. Critical awareness of unsustainable practices increased. Individuals were able to effect change, but it is recommended that such actions should be institutionalised for such changes to be sustainable. Limitations and recommendations emphasise the need for continuing PAR to implement sustainability. / Educational Studies / M. Ed. (Environmental Education)

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)

Reverse logistics is an important process that is often misunderstood. Reverse logistics can cause considerable cost, but provide numerous opportunities. Many organisations do not understand the correct processes and procedures to follow and how to manage reverse logistics efficiently. The focus of this study was on best practices in reverse logistics. A best practice framework was developed to help organisations overcome problems and manage their reverse logistics more efficiently. This study adopted a mixed method research approach with both qualitative and quantitative elements. A comprehensive literature study was conducted to develop a conceptual best practice framework in reverse logistics and a survey was conducted to seek inputs from industry in South Africa to refine the framework into a workable instrument in practice. The study concluded that the best practices identified in literature have proven to be important in practice, and applying such practices will enable organisations to manage their reverse logistics more efficiently. / Business Management / M.

Bibliographical refernces appear at the end of each chapter / This study reviews solid waste management practices in Polokwane City. The study area covered some of the residential areas in Polokwane City; namely; Ivy Park, Fauna Park, Welgelegen, Westernburg and the City Centre. This article describes two main methods that were used to collect data; that is Qualitative and Quantitative method. Field survey was also made to validate data obtained from the participants that were interviewed during qualitative data process. After framing the problem, the objectives of Solid Waste Management Practices in Polokwane City were briefly outlined as follows: • Assess solid waste management practices in Polokwane City. • Make comparison on how households and the municipality take responsibility in storing, collecting, transporting, treating and disposing solid waste. • Investigate what problems the City encounters in managing solid waste. • Make relevant recommendations aimed at improving solid waste management practices within the City. The service management was administered by the municipality and private sector. From the five study residential areas, the Municipality manages waste in the City Centre while the private sector manages waste in the other residential areas. However, the City continues to play an administrative role over the contracted service provider. Statistical results were presented in figures and tables. The results showed the storage habits, frequency of collection, mode of transport and methods of disposal for solid waste in Polokwane City. The only method of disposal in the city was found to be landfilling. Activities that took place at the landfill site, such as reclaiming were outlined together with the economic values that these activities add to the City. The study also revealed that as population increases, the amount of solid waste generated also increased. / 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

There has been a growing need in environmental education to develop students' ability and will to take part in democratic processes that enable them take environmental action in their local environment. This study examined learner action competence in waste management practices in two primary school contexts in the Eastern Cape, South Africa. An interpretive case study design is used to probe how learner participation in Eco-School waste management practices enabled the acquisition of knowledge in purposeful learning and action experiences that developed the vision and agency of informed action. The research was centred on two guiding questions: 1. How informed, purposeful and action-orientated is learner participation in Eco-School waste management activities? 2. What Eco-School waste management activities are fostering active participation towards a learner-led agency? Educators in the two schools were interviewed and Eco-School portfolios were examined for evidence of the learning activities and learner achievement. This provided the contextual data for reviewing focus group interviews to probe what was significant to learners, what they came to know and how they had contributed to the process of developing better waste management in the Eco-School context. The evidence generated in the study was used to identify the roles of the various players, the significant activities and processes that enabled and constrained the emergence of learner-led agency. The main findings in the study were that teacher intentionality and school management ethos were significant in engaging learners in meaningful waste management activities in both cases. The study also revealed that although most of the waste management activities in both cases were teacher-initiated, there were spaces open for learner initiatives. However, it appeared that the activity based waste management practices mostly allowed learners to learn how to do waste management more than allowing them to find out more about the scope and nature of ii the problem of waste. This then resulted in learners talking more about what they were doing with waste than talking about what they knew about waste. There were differences in the way in which learners approached waste in the two cases. In the one case, Kingswood Junior School learners used waste artistically and carried out activities that allowed for better use of waste resources like paper while in the other School, Grahamstown SDA School, learners approached waste as a resource for making money. However, in both cases, learners appeared to enjoy the positive experiences of doing things that contributed to a cleaner environment and were of benefit to others and this gave them a sense of pride to share their experiences with others. This study was significant as it allowed me to probe learner participation and examine the development of their action competence through listening to the voices of the learners themselves and understanding what was important to them about the knowledge they gained and their vision of better waste management.
