Plants are masters at capturing CO2 from the atmosphere – but once they are burned or rotted, it is released back into the atmosphere. Biochar offers a great alternative to this. The German company minus CO2 factory 001 in Eberswalde turns woody biomass or even grass into biochar, biogas and bio-oil – storing CO2 for hundreds of years.
The biochar can be used as a soil amendment in agriculture or mixed with plastics to make biocarbon composites, the bio-oil can be sold to the chemical industry and the biogas is an energy source.
The GO-GRASS project will be completed in 2024.
