As discussed earlier, biochars can have benefits for waste reduction, energy production, C-sequestration, and soil fertility. Also, different biochars (derived from a variety of feedstocks) have been recognized as highly efficient low-cost sorbents for various pollutants in the environment. Application of biochars to soils has been investigated at the laboratory and field scale as an in-situ remediation strategy for both organic and inorganic contaminants to determine their ability to increase the sorption capacity of varying soils and sediments. For example, Chun et al. (2004) reported biochars generated by pyrolyzing wheat residues at temperatures ranging from 300oC to 700oC removed benzene and nitrobenzene (organic contaminants) from wastewater. Similarly, biochars produced from greenwaste (a mixture of maple, elm, and oak woodchips and bark) removed atrazine and simazine from aqueous solution (Zheng et al. 2010). Pine needle-derived biochar removed naphthalene, nitrobenzene, and m-dinitrobenzene from water (Chen, Zhou, and Zhu 2008). Straw-derived biochar was found to be an excellent, cost-effective substitute for activated carbon to remove dyes (reactive brilliant blue and rhodamine B) from wastewater (Qiu et al. 2009). Biochar derived from dairy manures (pyrolysis from 200°C to 300°C) also removed substantial amounts of atrazine from wastewater (Uchimiya et al. 2010).
