Study of Straw-Biochar on Utilization Potential,Industry Model and Developing Strategy in Northeast China

As a strategic emerging industry, straw-biochar technology and its industrialization are beneficial to systematically and comprehensively solve the prominent problems of straw burning, straw utilization and soil degradation in Northeast China, which has large cultivated land and crop straws resource, thus become a hot research topic. Based on the systematic analysis of nearly 20 years in the Northeast China of straw resources dynamic change, availability utilization resource and development trend, this paper discussed the resource base, technic approach and development potential of straw-biochar utilization, and from an industrialization perspective to comprehensive analyze the resources, technology, conditions, advantages, markets and development potentials of the biochar-industrialization development in Northeast China. Our research results showed that the straw-biochar industrialization had rich available utilization biomass resources, mature industrialization conditions, and huge development potential and space in Northeast China, which had great significance and value on promoting the straws resource utilization, the cultivated land quality improvement and agricultural sustainable development in Northeast China. Finally, based on the actual situation of agricultural, economic and social development, we constructed the straw-biochar industry model including the whole industrial chain, and put forward the development strategy suggestions to the biochar industrialization in Northeast China, aiming at providing reference for solving the practical problems of straws processing and agricultural production, and promoting the healthy and stable development of biochar industrialization.
