Lecturer Dr. Gerhard Soja from BOKU Vienna shows in the first linked video the potential of biochar for the remediation of contaminated industrial soils and explains that different uses require different types of biochar.
In another video, Ilmo Kolehmainen from Carbons Finland Oy Ldt. from Finland presents approaches for the treatment of urban rainwater with biochar. The presentation will be held in English.
Biochar is characterized by its highly porous structure. This results in an enormous specific surface of sometimes more than 300 m² per gram. Due to this property, biochar can absorb up to five times its own weight in water and the substances dissolved in it.
