Carbon coating gives biochar its garden-greening power

Read the full story at Colorado State University. For more than 100 years, biochar, a carbon-rich, charcoal-like substance made from oxygen-deprived plant or other organic matter, has both delighted and puzzled scientists. As a soil additive, biochar can store carbon and thus reduce greenhouse gas emissions, and it can slow-release nutrients to act as a …

Ag Energy Solutions finds unexpected market for biochar

Read the full story in the Spokane Journal of Business. Carbon Logic, the first product line to be produced by Ag Energy Solutions Inc., of Spokane Valley, is going to pot—yes, the green leafy stuff. Ag Energy originally was formed in 2010 to make equipment to convert agricultural waste into energy. For now, however, the …

New model suggests scrubbing CO2 from the atmosphere

Read the full story from Cornell University. New Cornell research suggests an economically viable model to scrub carbon dioxide from the atmosphere to thwart runaway, point-of-no-return global warming. The researchers propose using a “bioenergy-biochar system” that removes carbon dioxide from the atmosphere in an environmental pinch, until other removal methods become economically feasible and in …
