M.Tech. / The majority of low income households in South Africa are based in either informal settlements or low cost housing. These households use paraffin as their primary fuel source for cooking and heating. The objective of this study was to identify design factors that should inform paraffin stove design. These factors include the design process, the problem context, the problem identification, the understanding of stove safety and interface issues through laboratory testing, understanding the user through user testing and developing recommendations from the research of these factors. The four main problems associated with paraffin usage as identified in this research are unsafe stoves, fires caused by these appliances, the high levels of emissions given off by these appliances in small enclosed households and issues related to the storage of paraffin that leads to the accidental ingestion of paraffin. The outcome of this research includes a set of findings and recommendations which were compiled to inform the design of future paraffin stoves. Finally, this study reflects on a commercial design process that was used to develop a series of design solutions for the Paraffin Safety Association of South Africa’s paraffin stove design competition in 2005.

A dissertation submitted to the Faculty of Science, University of the Witwatersrand, in fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2015. / Over 60% of the Swazi population resides in rural areas and rely on woodfuel for their daily cooking needs. Cooking with woodfuel on open fires is inefficient and unhealthy, leading to millions of deaths of women and children each year while also contributing to environmental degradation. This has necessitated the implementation of Government’s clean cookstoves programme in Swaziland. This study focused on household stove users in six chiefdoms in the Lower Usuthu Sustainable Land Management (LUSLM) Project area in Siphofaneni Swaziland. A survey conducted through the dissemination of a questionnaire was used to investigate how rural perceptions impact on the adoption of clean cookstove technologies as an alternative household energy technology contributing towards sustainable development in rural Swaziland. Results from this study indicate that although cooking on an open fire was the least desired cooking technology, only 2% of households in the project area own clean cookstoves and less than half of the households had knowledge of cookstoves. The study further revealed that over 80% of the households in the survey area would prefer using a clean cookstoves to reduce the labour intensive task of collecting firewood as well as reducing exposure to smoke. The households found to have some knowledge of the benefits of clean cookstoves indicated the willingness to pay for a clean cookstove; however, a third of the respondents indicated a preference of obtaining a free clean cookstove. The price and availability of the clean cookstove in rural areas were two main barriers to increased uptake of the stoves, coupled with the need to purchase new pots. Despite the general lack of awareness of these technologies, challenges such as danger of the stoves to children and stove durability were also cited. The results indicate the need for the ongoing clean cookstove programme being implemented by the Government of Swaziland to improve on its strategy, to focus on incorporation of perceptions of rural stove users in development of appropriate cookstove designs, distribution models, and the design and implementation of a cookstove quality control programme.
