Inspired by Stockholm’s success, a U.S. city goes big on biochar

Minneapolis is already using biochar to bolster urban agriculture. After three city leaders visited Stockholm in May, Minneapolis is considering new uses for the carbon-capturing soil additive.

Biochar is nothing new in Minneapolis. The city has, for years, bought truckloads of the charcoal-like material from a plant in Missouri and used the dusty black nuggets for a well-known use: to enrich soil for urban agriculture and bolster the local bounty of fruits and vegetables to harvest.
