Characterization of Biochar-blended Composting of Regional Waste Biomass

Abstract

The fixation of carbon dioxide is one of the most important subjects in environmental research. The general approach to removing carbon from the atm. is to grow plants that sequester carbon dioxide in their biomass by photosynthesis. Recently, biochar, which is produced by the pyrolysis of trees, grasses or crop residues, has been undergoing a renaissance as a method for sequestering carbon dioxide. A new compost contg. biochar was applied. The composting of agricultural and food industrial waste biomass occurred by the degrdn. of org. compds. by aerobic microorganisms in nature. Biochar has porous structures so that the blending of biochar into compost creates an aerobic environment which leads to the activation of aerobic microorganisms and the degrdn. of org. compds. in compost. A biochar-blended compost was made using waste biomass in Aomori. The biochar-blended compost contained a high amt. of microorganisms. The growth of some vegetables was accelerated by treatment with this compost compared to ordinary compost. Thus, biochar-blended compost has potential to be used in methods for the recuperation of degraded soil and the formation of soil environment. [on SciFinder(R)]
