The thesis proposes a new approach to assess sustainability of waste management systems. In the first part current mixed municipal waste (MSW) management system of the Czech republic is reviewed and promising MSW treatment techniques are introduced. In the second part a summary of literature on Life Cycle Assessment (LCA) approach to assess sustainability of MSW systems is provided. A new sustainability assessment model is proposed by implementing LCA to a current tool called NERUDA used to optimize waste management costing. It is demonstrated how to connect these two concepts in order to aquire a powerful tool for sustainability assessment.

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 City of Tshwane is the capital city of South Africa and the administrative seat of government. The status of the city as a capital creates high expectations on the level of basic service delivery on municipal services like waste management, water, electricity and health. The city is currently facing challenges in relation to the delivery and implementation of waste management services. In an attempt to find solutions to the waste management challenges of the city a study on the implementation of waste management services is undertaken by the researcher. The study identifies and then analyses the underlying reasons for the challenges faced by the City of Tshwane in the implementation of waste management services. This aim of this study was to investigate and to analyse the implementation of waste management services in the City of Tshwane’s historically disadvantaged areas with particular focus on Region 01, 02, 05 and 07. In order to investigate these factors, a descriptive research design and qualitative methodology was used which related to convenient and purposive sampling of officials and data collected from fifteen (15) respondents using semi structured interviews and observations. The study also utilised document analysis to interpret the challenges and solutions related to the research topic. It emerged from the study that a lack of capacity and resources to perform efficient waste management services underpinned many of the challenges experience by the city. The failure of the city to ensure community participation and involvement is another reason for the challenges the city faces in waste management. Furthermore, the lack of policy implementation and enforcement is an element that the city needs to deeply consider. When policy is crafted with input of residents and when there is a social contract as to the roles and responsibilities of each party, it becomes easier to enforce. Some of the challenges that the city faces with regards to waste management can also be attributed to political interference and institutional deficiencies. Beyond issues like capacity, institutions and others, the city will continue to face challenges if it does not seriously invest in innovation and new technologies that address its generic and specific conditions in relation to the management of waste. The marginalisation and selective enforcement of by-laws on the informal recyclers and reclaimers are some of the findings of the study that demonstrate the inability of the city to find specific solutions to specifics regions on waste management .These challenges resulted in the peri urban regions like region 01, 02, 05 and 07 not receiving quality and consistent waste management services. The study recommends some interventions to address the waste management problems identified in the highlighted regions and entire City of Tshwane. Some of the recommended interventions include, assessing the unique characteristics of the communities and regions with a view of identifying waste management solutions that will be relevant for the circumstances and profile of such regions, ensure that proper and adequate resources, infrastructure and capacity is deployed to such areas to improve the waste services in those areas. Furthermore aggressive education and awareness campaigns conducted in partnership with communities will be critical to change people’s attitude towards waste management and a clean environment. This can be achieved through a consultative process led by the City of Tshwane in partnership with its communities and enforced through a progressive and incentive driven by-law system. / Public Administration and Management / M.P.A.
