Biochar products are not structurally homogenous material but consist of a wide range of heterogeneous elements and chemical structures. This erroneous conception is generally based on the parent material (biomass) and the pyrolysis conditions while covering numerous forms of black carbon. These characteristics lead to a wide spectrum of particle sizes, electrical conductivities, and surface areas among the different products. Biochar products are known to have environmental benefits by connecting the charring biomass to the soil, a step towards environmental management and technology also applied in land administration. Suspected advantages consist of increased soil fertility and crop yield. This paper determines the applicability of biochar products for environmental management and technology, its impacts and effects on soil and soil biota. Various techniques used in the production of biochar are discussed as well as the manufacturing costs on small, medium, and large scales.
