Full-scale gasification biochar reduces soil pollutant leaching risks

Zusatztext

Application of biochar to sandy loam soil to reduce leaching of organic pollutants e.g. hydrocarbons, pesticides or antibiotics were investigated. The wood-derived biochar evaluated in our study was the solid co-product of a full-scale gasifier feeding a combined heat and power plant. The research aimed to demonstrate multiple environmental benefits with the innovative use of this biochar as a soil improver. Batch sorption experiments indicated biochar added to soil enhanced the partitioning coefficients. Column leaching experiments indicated a reduced porewater flow rate and therefore reduced pollutant leaching risks. Numerical models interlinked batch and column study observations.
