Abstract
The fixation of carbon dioxide is one of the most important subjects in environmental research. The general approach to removing carbon from the atmosphere 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. In our research, we applied a new compost containing biochar. The composting of agricultural and food industrial waste biomass occurred by the degradation of organic compounds 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 degradation of organic compounds in compost. In this study, we made a biochar-blended compost using waste biomass in Aomori. The biochar-blended compost contained a high amount of microorganisms. The growth of some vegetables was accelerated by treatment with this compost compared to ordinary compost. These results indicated that our biochar-blended compost has potential to be used in methods for the recuperation of degraded soil and the formation of soil environment.
