Biochar, a type of charcoal made by slowly burning waste biomass under low-oxygen conditions, could become an unheralded way to help mitigate climate change. The carbon-based material could also assist in cleaning up abandoned industrial, mining, agricultural, and landfill sites, known as brownfields, and restore them for agricultural and other uses. Those are the conclusions of a study carried out by an international team led by Jingchun Tang of Nankai University, in . . .
