Abstract

Carbon emission reduction is an important issue facing the current industrial development. With the agglomeration of old industrial bases in Northeast China and the high total carbon emission, it is difficult to achieve the goal of carbon neutrality. The objective of crop straw biochar preparation and utilization research is to achieve regional carbon neutralization and carbon sink function. The waste crop straw resources in Northeast China were huge, with an annual yield of about 7.0 × 10 7 tons which showed an increasing trend. The development of the biochar industry in Northeast China significantly reduced carbon emissions and the environmental pollution caused by straw burning. At the same time, it obtained a huge profit of 7.0 × 10 10 RMB. Because of the special location conditions in Northeast China, the establishment of the biochar industry chain needed multi-angle research and judgment. The biochar industry in Northeast China will have a broad prospect, and the industrial demand is not only farmland soil improvement but also winter heating fuel utilization and carbon reduction. This study will further increase the carbon sink capacity in Northeast China and promote the realization of China’s carbon neutrality goal, which also has important reference value for carbon reduction in other countries in the world.
