Doubling nature with biochar

Student and entrepreneur Marcel Kempers made an agile start of this decade, working with his companies on seaweed (Reef Support) and biochar (Pyro Power). At our Double Nature Talk of February 10 Marcel and his collegues elaborated on the latter one: regenerating soil using biochar. An ancient method used for centuries by indigenous people in the Amazon.

This Double Nature Talk will soon be published on YouTube.
