In South Africa’s Limpopo province, Tiyani Secondary School feeds over 1,000 students using cooking fuel generated from cattle dung collected by local volunteers, reducing reliance on firewood and easing pressure on nearby forests.
- Biogas generated from community-collected cattle dung powers school cooking.
- Project reduces firewood use and protects local forests in Limpopo.
- Success depends on community involvement and reliable manure collection.
What happened
Since 2022, Tiyani Secondary School has integrated a biogas system fueled by cattle dung gathered from nearby homes in Tiyani village. Community volunteers collect manure using an ox-drawn cart, which is then mixed with water and processed in a sealed biogas digester. The methane-rich gas produced is piped directly to the school kitchen, where it powers stoves used to prepare breakfast and lunch for over 1,000 students.
This project was established in partnership with the University of Venda to address the unsustainable use of firewood and make productive use of livestock waste. While firewood is still sometimes needed, the biogas system has become a vital alternative energy source, showing promising results in efficiency and environmental impact.
Why it feels good
This initiative not only reduces the pressure on local trees, helping protect the surrounding forest ecosystems, but also cuts down greenhouse gas emissions by capturing methane that would otherwise escape from decomposing manure. It exemplifies how innovative, community-driven solutions can turn what was once considered waste into a valuable resource.
The involvement of local volunteers in collecting dung fosters a sense of ownership, while the collaboration with the University of Venda brings essential technical expertise. The project demonstrates a sustainable pathway for rural communities to meet energy needs with minimal environmental harm.
What to enjoy or watch next
Looking ahead, expanding the biogas system with additional stoves and improved transport for manure collection could increase the project's impact. Overcoming current challenges—such as the limited number of gas stoves and varying participation from cattle owners—will be key to the project's growth and sustainability.
Similar community-scale biogas projects around the region are worth watching, as they offer scalable models for cleaner cooking fuel and methane emission reduction. Success stories like Tiyani’s encourage broader adoption of renewable energy methods that benefit both people and the planet.
