5This book offers chapters on the heritage skills of earth burns, the enduring popularity of metal kilns, and the future represented by the charcoal retort. Biochar--or small particle charcoal--has been heralded as a "super substance" that can increase soil fertility and productivity while locking up carbon into the ground. Covering business essentials such as legislation and marking, there are also chapters on why charcoal is in the ascendancy from the ubiquitous barbecue to recent research into biochar from carbon sequestration.
