Using pyrolysis is preferable to using gasification because by burning the biomass gasification destroys the honeycomb structure of biochar. The reason to maintain the microscopic honeycomb structure is that biochar’s nooks and crannies act as a “house” for symbiotically beneficial microbes, bacteria, and enables better storage of nutrients. If this house structure is weakened or destroyed during the gasification process, then any biochar produced will be less effective. Pyrolysis is also a much cleaner, more efficient method of manufacturing biochar. Gasification prioritizes energy generation with any biochar/carbon black “leftovers” being an afterthought. Pyrolysis processes vary, but we’ve designed our machine to make the best biochar and wood vinegars first, with energy generation being an ancillary benefit.
