Appropriate Energy-Saving Technologies

Increasing household access to clean energy and clean cooking solutions
2014 SEED Africa Award Winner Waste Management Soroti Town, Uganda

Appropriate Energy Saving Technologies LTD (AEST) utilises local resources like agricultural bio-waste to manufacture charcoal briquettes. It markets its products in combination with fuel-efficient cook stoves, modified by the enterprise for household use. Local women and youth are employed to help produce, market and sell the goods. 

AEST hopes to transition to a more decentralised production model by contracting farmers to supply biochar which will be processed further by the enterprise to ensure briquette quality. 

Increasing community access to sustainable energy and improved cooking solutions has multiple benefits. Socially, the enterprise is helping to reduce illnesses related to smoke inhalation. It is also providing an alternative solution to women and children walking long distances to find fuel.
