Product Description

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.

Manufacturer Specified Performance Parameters

The key benefits of having an ATEC biodigester are:
  • Free gas for all cooking needs
  • 20 tons of organic fertilizer
  • Modern kitchen, no smoke or dirty pots
  • Can be easily moved when and where required
  • Export-quality materials, leading Australian design
  • 2-year warranty, after-sales service, 25-year life span
  • Flood and high groundwater resistant
By having a biodigester an average Cambodian family will save an average family $521 per year. 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

Vetted Performance Status

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.

Safety

ATEC biodigester aims to reduce the potential health risks linked to the burning of traditional biomass and domestic accidents such as accidental burning or spill-overs in traditional open fires cookstoves. No known safety concerns can be associated with this product.

Complementary Technical Systems

The biodigester is complemented with the twin cookstove and the biogas rice cooker.
