The Anaerobic Digestion Pasteurization Latrine (ADPL)

We are developing a low-tech technique for decentralized sanitation: the ADPL or Anaerobic Digestion-Pasteurization Latrine. This is a self-contained and energy neutral sanitation system that relies on anaerobic digestion to generate biogas then used to heat-sterilize the treated effluent. Development in conducted in the lab, and implementation occurs in the field, with partners in Kenya, the Philippines, and India.

We are currently evaluating five prototypes in three different locations: Kenya, the Philippines and India.

The ADPL holds promise for decentralized sanitation in rural or peri-urban areas.
