Abstract
Biochar are charcoal particles mixed with soil. Participants will learn about building a portable flame cap kiln for demonstrating how to make biochar with clientele. Details such as burn permits, fire safety, a water source, and lighting and quenching the fire are discussed. Emerging markets for biochar include: 1) An agricultural and horticultural soil amendment that improves water and nutrient availability; 2) Contaminant adsorption for dairies, landfills or mining; 3) Hazardous fuels reduction in forests and wildland urban interface communities, as well as reduction of yard waste; 4) Production of bioenergy fuels including syngas and bio-oil; and 5) direct carbon sequestration: the half-life of a biochar molecule is 1,000 years. Benefits and challenges of using biochar are discussed, including raising awareness about biochar; creating markets; feedstock properties and variability; and matching biochar qualities to specific applications. Biochar is popular with early adopters.
