Permanence MEDIUM 100-1000 years
Biochar is a charcoal-like substance rich in stable carbon, made by heating biomass (wood, crops and other organic waste), in a low-oxygen environment through pyrolysis. It's mainly used in agriculture and gardening to improve soil.
Biochar is produced from waste biomass, which stores carbon captured by plants. Without pyrolysis, this carbon would be released back into the atmosphere when the biomass decomposes or burns. Although biochar can be burned, adding it to soil keeps the carbon stored.
Using biochar in soil offers extra benefits like better crop yields and lower fertiliser needs. It stands out from
other carbon removal methods because it not only sequesters carbon for centuries but also enhances soil quality and reduces the environmental impact of food production.
Removal provider
Supercritical offers biochar as one of their main carbon removal methods due to its scalability and potential for permanent carbon sequestration. Supercritical highlights the medium permanence of biochar (100-1,000 years) and its significant co-benefits for soil health and agricultural productivity. The company ensures the quality of biochar credits through a detailed vetting process that assesses climate science, environmental impact, and social benefits.
