This project was realized in 2018/2019 in Linga Linga, Inhambane by Mila Ebrahim and Fanny Lilja. They were two students from the Engineering Programme, Energy and Sustainable Development at the Royal institute of Technology, KTH in Stockholm. The title of their Bachelor Thesis is; The feasibility of producing and utilizing bioenergy in Linga Linga, Mozambique – Potential resources, conversion techniques and applications. It was funded by Sida, Swedish International Development Cooperation Agency, as part of their Minor Field Study programme, MFS.
The students investigated how one could use biomass from waste as a source of renewable energy for households in rural areas of Mozambique. They limited the scope of the project to find an alternative way of cooking due to the cooking method of using firewood as fuel creates a lot of smoke. According to World Health Organization, WHO indoor air pollution in households in developing countries is the main cause of diseases and early death. Furthermore, cutting down trees in an unregulated manner creates a problem of deforestation. Saving time on not having to gather firewood allows for the women to get involved in other activities such as education or entrepreneurship.
Therefore, Fanny and Mila designed a gasifier cookstove that could make charcoal out of coconut shells from household waste. The concept was developed based on input from interviews with women from the village, combined with tests of creating charcoal and boiling water. A prototype was built using local materials which ease the potential for others to duplicate the prototype. The next step would be to look at business models for how people from the village could use a gasifier cookstove to create an income for their household based on selling charcoal.
