The development of the biomass industry requires biomass to become a general industrial raw material in the field of biochemical engineering. The raw material structure, process transformation and product characteristics should be organically linked, and refining technologies that enable selective structural separation and directional transformation of biomass raw materials should be developed. , Not only to obtain products, but also to achieve clean conversion with the lowest energy consumption, the best efficiency, and the greatest value. Analyzed the resource status, industrial prospects and current difficulties of the biomass industry, and proposed that breaking through the key technical constraints and solving technical and economic problems is the fundamental way to realize the industrialization of biomass. Under the refining idea of ​​hierarchical multi-level directional transformation, relying on the breakthrough of key technologies in the biomass industry and process integration, and taking the road of diversification of raw materials and products, the spring of the development of the biomass industry has arrived.

The biomass industry uses crop stalks, livestock manure, organic waste and other agricultural and forestry wastes and environmental pollutants as raw materials to make them harmless and resourceful. The solar energy and material resources stored by plants are deeply developed and recycled. A model of circular economy. Vigorously develop the low-carbon biomass industry based on biomass energy, and partially replace and save fossil energy, which is conducive to improving the energy structure, reducing carbon dioxide emissions, and mitigating and responding to global climate change [1]. The biomass industry is the best fit and entry point for low-carbon economic development and clean energy substitution.

Low-carbon economy focuses on reducing greenhouse gas emissions, and CO2 emitted by fossil fuels is the largest source of greenhouse gases, so "CO2 emission reduction" is the most intuitive manifestation of a low-carbon economy. The reduction of CO2 emissions should start from eliminating the root causes. First, reduce carbon sources, develop biomass industries, produce biomass energy and bio-based chemicals, and reduce dependence on fossil fuels; second, increase carbon sinks, restore and strengthen the planet’s vegetation Construction, fix CO2 through tree planting and afforestation, develop carbon sink forestry, realize the increase of forest area, increase of forest stock, and finally realize forest ecological benefits. The use of renewable energy, the development of the biomass industry, the promotion of economic development and the ultimate decoupling of carbon emissions, and the realization of industrial emissions reduction are our focus. Through the establishment and development of the biomass industry, the four major areas of circular economy, energy saving, clean production and industrial adjustment will be integrated.

1 Biomass resources and industry prospects

Biomass industry is an emerging industry that uses environmentally friendly renewable resources to produce clean energy and related chemical products. Considering the depletion of resources, energy security, environmental protection, and sustainable development of circular economy, the establishment of a low-carbon biomass industry is the general trend of the development of circular economy.
