Ag Waste Can Build a California Carbon Sink. Iowa-based technology company Frontline BioEnergy proposes to convert about 300,000 tons per year of nut shells and ag waste and turn it into natural gas equivalent to 21 million gallons of gasoline. It would also generate an estimated 125 tons per day of biochar, a versatile byproduct whose uses may include fertilizer.

Tracking Down the Waste in Canada. A new biomass tracking project from Agri-food traceability firm TrustBIX, will divert material from landfill, and help produce quality biochar Tracking the source, characteristics, and use of various waste streams supports biochar product quality, production practices, suitability for specific applications, and pricing in various markets. Tracking also helps determine the climate impact of the waste diversion.
