Seeing refugees at Zimbabwe's largest refugee camp struggle to dispose of animal waste, UNHCR thought biogas might be a solution. The Tongogara camp has installed machines that let refugees turn animal waste into biogas that can be used for clean, smokeless cooking and fertilizer for gardens. Both the biogas and the fertilizer produced after the waste ferments in the digesters are free to refugees. The biogas project is a cost-saving initiative meant to ensure that refugees get clean energy, said camp administrator Johanne Mhlanga. Refugees are integrated into (a) modern way of having fuel or green energy. Zimbabwe, which is losing 330,000 hectares of forest annually, says the project will help reduce deforestation near the camp, which has about 20,000 people, and hopes to secure more funding to expand the project.
