John Miedema of BioLogical Carbon Inc., Philomath, Ore., makes biochar at a wood processing plant and explains his process in this video.

Perry Morrow, student in the Oregon State University Water Resources Graduate Program, produced this video on biochar, the carbonized remains of plants. Turning low-value wood and other biomass into biochar sequesters carbon from the atmosphere for hundreds of years. The resulting material may also benefit water quality by absorbing pollutants such as copper, lead, zinc and other metals.
