At this stage, the overall technology of China's waste and renewable resources industry still has a lot of room for improvement. From an objective point of view, with the tightening of supervision and the "dual carbon" goal stimulating market demand, the role of waste renewable resource technology in the development of the industry in the future is becoming more and more prominent. The increasing environmental protection requirements accelerate the clearance of renewable resource production capacity with backward process level, large pollution emissions, poor operation stability and low load ratio. With the establishment of the carbon trading system and the increase in emission costs, enterprises are more willing to reduce emissions through recycling and increase the demand for high-quality renewable resource products.
