The Anaerobic Digestion Pasteurization Latrine (ADPL)
The Anaerobic Digestion Pasteurization Latrine (ADPL) is designed to provide clean, sustainable, self-sanitizing, 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.
The ADPL and its components were developed in the lab at Duke and evaluated in Kenya, India, the Philippines and Madagascar between 2011 and 2019. The R&D included system development, system optimization, ancillary post-treatment development and demonstration, field demonstration and assessment of pathogen reduction.
