The Anaerobic Digestion Pasteurization Latrine (ADPL) is designed to provide clean, sustainable, odor-free latrines for communities of 20-50 people with no water supply or energy source required. The ADPL includes its own self-contained, energy neutral on-site sanitation treatment. Anaerobic digestion of the human waste generates biogas which is burned to pasteurize the system’s liquid effluent. The effluent poses no health hazard and may have potential value for agricultural irrigation or other uses.
Currently, three ADPL units are being evaluated in Kenya, one in India and one in the Philippines. The team is working on additional performance and monitoring enhancements to the system.
