Research and Application Progress on the Preparation of Biological Carbon from Waste

Bio-carbon can be prepared from a wide range of raw materials and obtained from most of waste through carbonization. Bio-carbon is a kind of adsorption material with porous structure and diverse functional groups, which has application prospects in pollution restoration and soil improvement. This paper reviewed various materials that can be used to prepare bio-carbon, generalized about the commonly used methods of bio-carbon preparation, and the characterization characteristics of bio-carbon and summarized the research and application of bio-carbon in repairing polluted environment, improving soil environment, and as a new type of fertilizer in order to find out the key points and direction of resource application of bio-carbon preparation from current waste, and made a prospect of the quantitative preparation and largescale application of bio-carbon.
