Biochar is a stable carbon-rich material produced from biomass (wastes) during bioenergy production. Since it is produced as a by-product from waste biomass during production of fuel, it can be considered a sustainable material. The unique properties of biochar such as high internal porosity, high intrinsic surface area, high moisture and nutrient retention capacity, and high adsorption capacity make it appealing for wide range of applications. Biochar has found use in variety of applications ranging from soil amendment for improved crop yield in agriculture, soil stabilizer in construction, to environmental remediation media. Biochar is shown to be effective for nutrient removal from wastewater, mixed contaminant removal from stormwater, contaminated soil remediation, and fugitive landfill gas mitigation. Although biochars have amenable properties for wide range of applications, their properties may vary significantly depending upon type of feedstock, production process, processing temperature, and residence time. Hence, all the biochars are not the same and cannot be used in all applications. It is crucial to perform complete characterization (including contamination content, if present) of the biochar before planning to use in any application. Moreover, biochars can also be customized as per the project requirements which offers potential for unlimited use of biochars. One of the challenges for economic and sustainable application of biochar could be local availability in required quantities, specifically for large-scale applications. Overall, biochar is shown to offer a sustainable solution to wide range of environmental problems.
