Construction to begin by the end of this month on a plant in Linden that will turn treated sewage sludge into biochar. Biochar is a form of charcoal but it’s not used as a fuel. The biochar produced at the Linden plant will be used as a substitute for fly ash in concrete.

Biochar can also be made from nut shells, wood chips and landscaping waste. Biochar has environmental value because it sequesters carbon and can filter agricultural chemical before they run-off into lakes and streams. Biochar is being embraced in New England.
