Biochar is a highly porous carbon-rich material produced by pyrolysis of biomass. The SEM image shows micropores in a wood-derived biochar sample. Due to its unique properties such as high porosity, large surface area, and presence of negatively charged organic functional groups, biochar is used as adsorbent for the removal of various contaminants in soil and wastewater. Biochar is a simple yet powerful tool for soil and waste management, energy production, and C-sequestration to mitigate climate change.
