Biochar Stoves:The Commercialization and Advantages

Biochar stoves are an exciting new technology that reduce poverty, improve health, curb climate change, increase food security and decreas desertification.
How? Biochar stoves gasify waste biomass such as grass, husks or dried manure to produce heat for cooking. The charcoal byproduct, biochar, is a carbon-negative soil amendment that increases water and nutrient retention thus increasing soil’s adaptability to the extreme floods and droughts of climate change.
