This step-by-step video demonstrates how to assemble a basic Top Lit Up Draft (TLUD) Biochar Kiln using a 200L metal drum. This is our preferred 'entry-level' method for biochar production, as it can be easily replicated in most settings. Biochar produced in this manner can be used as a soil amendment when mixed with compost or manure or used in a biosand water filtration system.
