ATEC Biodigesters International
Distributed by ATEC, this biodigester converts green waste into biogas for cooking and organic fertilizer for crops and comes along with a twin cookstove and biogas rice cooker.
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.

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.

ATEC’s main goal is to expand the biodigester to 5 countries and disseminate 1 million systems by 2030 so as to create the impact of:
9.5 trillion liters of eco-friendly renewable biogas (51 million MWh equivalent)
24.6 billion hours saved from collecting and using wood
1/2 billion tons of organic fertilizer
12.4 billion USD net income increase in households
5.4 million tons of forest wood conserved
75 million tons of Greenhouse Gas reductions
Payback of 16 USD for every 1 USD spent on the unit
Tests performed by Engineers Without Borders Australia found an average reduction in E. Coli pathogen level of 2-log order, between input and output E-Coli levels, es expected for an anaerobic biodigester.
