ERWAP Portable Biogas Digester System, including digester unit, gas storage bag, biogas stove, regulator, and accessories designed to convert organic waste into clean cooking energy.
Who This System Is For
This system is ideal for:
Designed to convert farm waste into up to 3–4 hours of daily clean cooking energy.
ERWAP Energy Biofuels is developing biomass gas stoves designed to provide efficient, affordable, and clean cooking solutions using sustainable fuels.
Our stove technology works with biofuel pellets and charcoal produced from waste materials, helping households and institutions reduce reliance on firewood and fossil fuels.
Prototype testing has been successfully completed, and the technology is now ready for scaled manufacturing and wider deployment.





Prototype biomass gas stove tested with pellet and charcoal fuels produced from waste materials.
Following successful pilot testing, ERWAP developed an improved CAD-based stove design informed by user feedback and field experience, positioning the technology for scalable manufacturing.
