Waste and waste management in Breede Valley district

Carolus, Vernon January 2007 (has links)
Thesis (MTech (Environmental Health))--Cape Peninsula University of Technology, 2007 / The waste management that is taking place in the Breede Valley district focus mainly on disposal and end-of-pipe solutions. This approach resulted in serious negative impacts on the environment and human health. Improper waste management practices have become a major source of concern due to the risk associated with poor waste management in the area. Indiscriminate dumping of waste at street corners is very common. The basic waste management processes of collection, transport, segregation and [mal disposal appear to be very inefficient and inadequate. The objective of this study was to determine the composition of the waste stream as well as public awareness, attitudes and behaviours towards current and alternative waste management practices. A waste assessment study was conducted to determine the amount of waste generated by the different communities, as well as how much and what of the recyclables can be taken out of the waste stream by recycling. For this study data was obtained by formulation of questionnaires for businesses, communities and medical practitioners, as well as an interview with the Engineering Department of the Breede Valley Municipality about the current waste management situation in the area. From the data obtain from businesses, communities and medical facilities, it is clear that public participation, partnership, education and awareness is essential for effective integrated waste management. This study revealed that waste management practices are inefficient, uncontrolled and fragmented. This investigation shows that there is a huge difference between the different communities in terms of the volume of waste generation. The study also shows that waste related legislation is outdated and fragmented and there is no enforcement by municipal officials. The major Issues and challenges that affect the management of waste. include its organisational structure and lack of waste minimisation plans.

"Skarrelling" : a socio-environmental history of household waste in South Africa

King, Giorgina F. J. 04 1900 (has links)
Thesis(MA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: This study excavates a century’s worth of the history of household waste in South Africa, from 1890-1996. It shows that waste history is entangled with histories of disease and poor sanitation, advances in technology, the impact of war, environmental concerns and – perhaps above all – shifting socio-economic circumstances. Using a socio-environmental analytical framework, this analysis of waste history unearths empirical archival data and oral testimony, to contextualise themes of gender, race, class and nationalism in order to place rubbish within the wider historical debates in South Africa. This study uses Rubbish Theory and Broken Windows Theory as well as concepts of “Othering” and the “Sanitation Syndrome” to explore the role of waste in the construction of racial identities and perceptions. This thesis shows that Apartheid should not be seen as a watershed within this waste history, but rather as a continuation of colonial ideas of cleanliness that helped to perpetuate racist stereotypes. This study argues that the lack of waste services in “locations” during this time helped to contribute to the perception of the urban African as the unsanitary Other. The state and civic societies fostered gender roles, which (coupled with wartime nationalist propaganda) helped in shaping waste behaviour promoted by the National Anti-Waste Organisation (NAWO) during the Second World War (WWII). In the years after WWII, the threats of wartime shortages and enthusiastic solutions suggested to municipalities to “end the waste problem” were thwarted by the spread of the landfill as an even more convenient disposal method. The implementation of Apartheid, especially the Group Areas Act (No 41 of 1950) and the rise of consumer society, led to increasingly divergent experiences of waste for urban Africans and whites. The thesis uses a case study of the Devon Valley Landfill community outside of Stellenbosch. This ethnographic history explores notions of the “Subaltern” in order to give this history a human face. The diachronic analysis of this community offers a lens into ideas of “ordentlikheid” (decency), “weggooi mense” (throwaway people) and how these waste-pickers experience the environment in which they live. / AFRIKAANSE OPSOMMING: Hierdie studie grawe ’n eeu se geskiedenis van huishoudelike afval in Suid-Afrika op, van 1890-1996. Dit toon dat die geskiedenis van afval verweef is met geskiedenisse van siekte en swak sanitasie, tegnologiese vooruitgang, die impak van oorlog, omgewingskwessies en – dalk bowenal – veranderende sosio-ekonomiese omstandighede. Deur middel van ’n sosio-omgewings-analitiese raamwerk ontgin hierdie analise empiriese argiefdata en mondelingse getuienis om temas van geslag, ras, klas en nasionalisme te kontekstualiseer ten einde afval binne die breër historiese debatte in Suid-Afrika te plaas. Die studie gebruik Afval-teorie en Gebreekte Vensters-teorie sowel as begrippe van “Othering” en die “Sanitasie-sindroom” om die rol van afval in die totstandkoming van rasse-identiteite en -persepsies te ondersoek. Die tesis toon dat Apartheid nie as ’n waterskeiding in hierdie afval-geskiedenis gesien moet word nie, maar eerder as ’n voortsetting van koloniale idees oor higiëne wat gehelp het om rasse-stereotipes te perpetueer. Die studie argumenteer dat die gebrek aan afvalverwyderingsdienste in “lokasies” in die tyd bygedra het tot die persepsie van die stedelike Afrikaan as die onhigiëniese Ander. Die staat en burgerlike samelewings het geslagsrolle gekweek, wat (tesame met oorlogtydse nasionalistiese propaganda) gehelp het met die vestiging van afval-gedrag wat bevorder is deur die National Anti-Waste Organisation (NAWO) gedurende die Tweede Wêreldoorlog. In die jare na dié oorlog is die bedreigings van oorlogtydse tekorte en die entoesiastiese oplossings wat vir munisipaliteite aanbeveel is om die “afvalprobleem te beëindig”, gefnuik deur die toenemende gebruik van stortingsterreine as ’n selfs geriefliker afvalverwyderingsmetode. Die implementering van Apartheid, veral die Groepsgebiedewet (No. 41 van 1950) en die opkoms van die verbruikersamelewing, het gelei tot toenemend uiteenlopende ervarings van afval onder stedelike Afrikane en wit mense. Die tesis maak gebruik van ’n gevallestudie van die gemeenskap van die Devonvallei-stortingsterrein buite Stellenbosch. Hierdie etnografiese geskiedenis verken denkbeelde van die “Ondergeskikte” om ’n menslike gesig aan die geskiedenis te gee. Die diakroniese analise van die gemeenskap is ’n venster op idees van “ordentlikheid”, “weggooimense” en hoe hierdie afvalontginners die omgewing waarin hulle woon, beleef.

An evaluation of the gaps and barriers that exist between the national waste management policy and its implementation in formal and informal urban areas in the Ekurhuleni Municipality, South Africa

Tembon, Mbamuku-Nduku Fayez 10 1900 (has links)
Waste management is a global challenge due to high waste generation resulting from high industrialization, urbanization and challenges relating to the efficient implementation of waste management policies acts and standards. Although South Africa has established a number of good waste management policies and related acts and standards, most municipalities still find it challenging to efficiently implement waste management strategies. Ekurhuleni Municipality is facing challenges with the implementation of effective waste management strategies and compliance to the National Environmental Management Waste Act (2008), (NEMWA) (Act No 59 of 2008). An evaluation of the gaps that exist between NEMWA and the local implementation in the formal and informal parts of the Ekurhuleni Municipality was undertaken in this study. Data on the waste management scenario as collected through questionnaires, interviews and observations revealed that differences relating to the poor establishment of an integrated approach to waste management exist between NEMWA and the local implementation of the act. This was realized through the fact that there is limited community education on waste management, no waste recycling facilities in some residences, irregular and insufficient collection of waste and non compliance with tariff payments for most informal residents and some formal residents. Differences also exist in the waste management strategies between the formal and informal areas of the municipality primarily due to the fact that the informal settlements are mostly unplanned and considered illegal. According to this study, informal residents are not billed for waste management services and as such most of them do not pay for waste management services. To that end, waste is not efficiently managed due to municipal financial constraints. Waste management challenges in Ekurhuleni Municipality are also attributed to lack of or insufficient knowledge regarding sustainable waste management practices and its benefits amongst the waste generators and some waste management employees. / Environmental Sciences / M.A. (Environmental Management)

Attitudes and behaviour of low-income households towards the management of domestic solid waste in Tafelsig, Mitchell's Plain.

Nshimirimana, Jules January 2004 (has links)
Solid waste management in South Africa has been focussing on the technical issues of waste disposal with little attention paid to the social and economic aspects of households. It is important to find out the impact of the attitude and perception of households on solid waste management, especially in low-income areas to be able to deal with the deplorabe domestic solid waste management in such areas. The quantity of solid waste generated in low-income areas is often assumed to be less than the solid waste generated in high-income neighbourhoods. In most of the townships of low-income households in Cape Town, the residents live next to mountains of solid waste which is not the case in middle and high income areas. This clearly has a negative effect on the environment and human health. Tafelsig is one of the low-income Cape Flats townships where the open spaces and green areas are dumping areas. The small yard that people own is often unclean. The aim of the study was to examine how households residing in the low-income neighbourhood (Tafelsig, Mitchell's Plain) view domestic solid waste and its management. The study explored the perceptions, attitudes and behaviour of these households towards the production and management of sold waste. Issues relating to the degradation of their environment and to solid waste mismanagement were also examined.
