Biochar (pyrolysis)

Pyrolysis is the thermo-chemical conversion of dry organic materials (i.e. woody wastes) into bio-oil, syngas, and biochar. Biochar is being promoted for its potential to improve soil properties, fertility and carbon sequestration in soil while also producing renewable energy. Research results on how this material might impact agricultural soils within temperate regions is contradictory. Validation of biochar as a beneficial soil amendment and carbon sink would add important economic value to the pyrolysis process and spur adoption. More targeted uses in the near term include improved nutrient efficiency and contaminant absorption. Studies on the use of bio-oil have also been conducted.
