Material and energy metabolism and zero-waste evaluation methods for industrial parks:A case study
"Zero-waste"city,the principles of industrial ecology,and the characteristics of the industrial park itself,based on the structural characteristics of material and energy metabolism,a comprehensive evaluation index system for"Zero-waste"park by industry category had been reasonably constructed,and the level of"Zero-waste"in the park(measured by environmental performance)had been quantitatively evaluated.The results showed that the energy output rate of the park was 42 000 yuan per ton of standard coal,and the resource output rate was 26 000 yuan per ton,with relatively high intensity.The comprehensive utilization level of solid waste in the park reached 80％in 2022,which was higher than the national average of 61.9％.Overall,the comprehensive score of the"Zero-waste"level(environmental performance)was 62 points(percentage).This was mainly due to the fact that the leading industries in the park were mainly traditional chemicals and pharmaceuticals,and the intensity of solid waste generation was high.Therefore,it is of great significance to continuously optimize the management of resources and energy efficiency to promote the construction of"Zero-waste"parks and the synergistic control of carbon and pollutants in the industrial field.
