Sophie Rudén and Matilda Stendahl were two students in 2016 that went on a field study to Quelimane in Mozambique with guidance from Project Vita. They studied the Engineering Programme Energy and Sustainable Development at the Royal Institute of Technology, KTH in Stockholm. The title of their Bachelor Thesis is, The Potential for Urban Anaerobic Digestion in Quelimane: A model and feasibility assessment of a small scale system implementation. The field study was part of the Minor Field Study programme, MFS by Sida, Swedish International Development Cooperation Agency. The study built on an earlier study conducted by the students in 2015.
Sophie and Matilda had found out that the waste management was handled by a small number of people for a large population. They interviewed and followed on-sight some of the people managing the waste to get a better understanding of the waste generated in the region and the employees working environment managing the waste. It was realized that most of the waste was organic waste, which could be managed through anaerobic digestion. The digestion process creates biogas, which can be used as cooking fuel. Air pollution indoors from cooking with firewood and limited ventilation is a severe problem in low-income countries.
The students selected suitable locations where one could start building anaerobic digesters as pilot studies. This could be a school or in a plantation handled by the municipality. One idea was that the waste from the local market could be used for the process, since it is the organic materials that create the biogas. The pilot projects could serve as a means to spread knowledge and awareness about the technology. The success of the system was by the students assessed to be highly dependent on social and cultural awareness.
