Converting biomass into stable carbon for soils – the process
The process includes:
- Biomass preparation and drying by hot flue gases to reduce moisture content to near-zero levels
- Thermal treatment without oxygen (pyrolysis) in the carbonization chamber where the biomass undergoes thermal decomposition into biochar products
- Energy recovery from produced gases (syngas). During the thermal treatment, syngas is generated and separated from the solid biochar. It is sent to a combustion chamber where the gas is mixed with air and burned, providing energy for the carbonisation process. Excess heat is used for biomass drying or can be used elsewhere.
The final product: Biochar, used as a soil amendment to improve water retention, nutrient availability and soil structure
