South Africa school uses cattle dung to generate biogas for cooking meals

Tiyani Secondary School in South Africa's Limpopo province has deployed a biogas digester powered by cattle manure to cook meals for 1,054 students, reducing dependence on firewood since the pilot project's launch in 2022. Four community volunteers collect dung daily, and the system now supplies much of the cooking fuel while reducing pressure on forests and methane emissions.

Long-term success depends on reliable manure supply and regular maintenance; the school currently has only one three-plate stove, limiting gas use.
