ATEC biodigester converts animal, organic, and kitchen waste into approximately 500 to 1500 L of biogas per day. The gas can be used for cooking and the organic byproduct is suitable to produce 20 tons of organic fertilizer per year for crops. This product is the first commercialized biodigester also suitable for earthquake and flood-prone areas. The system comes with a twin cookstove and a biogas rice cooker, along with the biodigester itself. The system requires a minimum of 2 livestock or 5 kg of green waste per day and there are two sizes available: 3,25 m3 for small-scale farmers and 10 m3 for medium-scale farms.
ATEC Biodigesters International is a triple bottom line impact enterprise operating in Cambodia.

Design specifications include the twin cookstove, biogas rice cooker, and the biodigester with a new rotor-molded design that uses export-quality UV-treated LLDPE plastic. The biodigesters collect and treat manure, human, kitchen, and green organic waste to be converted to biogas that powers the twin cookstove. The biodigester can be directly plumbed to the household's toilet system.
The product comes with a user training and 5-step after-sales-service program. For further support, users must contact the manufacturer.
The product has a 2-years warranty and an expected lifecycle of 25 years.
