摘要
针对废纸回收利用过程中的环境经济效益问题,定义了生态成本概念,对资源使用和废弃物排放的资源环境效益进行综合核算,定量计算其对生态环境的影响。通过物质流分析,明确各工序实物流量,将各实物量与各自的价位(处置成本)和LIME系数相乘,分别计算出内部成本和外部成本,进行加总后得到总生态成本,并计算得出废纸回收利用体系的生态成本。
In view of the environmental economic benefits in the process of waste paper recycling, this paper defines the concept of ecological cost(EC), accounts the environmental benefits of resources use and waste, and quantitatively calculates the impact on the ecological environment. On the basis of material flow analysis, the physical flow of each process is determined. And the internal cost and outside cost is calculated by the product of price(disposal cost) and quantity, and product of LIME coefficient and quantity, respectively. And the total ecological cost is the sum of internal and outside costs. Thus, the ecological cost of waste paper system is obtained.
