本文的创新之处在于证明了物质流分析(MFA)和物质流分析(SFA)相结合在废物管理决策中的有效性。MFA和SFA都是以质量平衡原理为基础的。虽然MFA经常单独用于定量分析物质流动，从而确定废物处理过程的能力，但SFA要求更高，但有助于评估废物管理系统在“资源节约”和“环境保护”目标方面的绩效。SFA侧重于废物处理过程中废物的转化：在整个废物管理系统中跟踪有价值的物质和有害物质及其转化。必须采取以物质为基础的办法，因为废物管理产品的经济和环境特性--回收物品、残留物和排放物--主要由特定贵重或有害物质的含量决定。为了支持MFA和SFA相结合的观点，给出了一个废物管理情景的案例研究。在三种情况下，总物质流量由MFA量化，六种指示物质(C、N、Cl、Cd、Pb、Hg)的质量流量由SFA确定。为了实现废物管理的目标，将综合结果与现状进行了比较。它们清楚地指出了所选方案之间的具体区别，展示了改进的潜力和多方案/小方案相结合对废物管理决策的价值。
The novelty of this paper is the demonstration of the effectiveness of combining material flow analysis (MFA) with substance flow analysis (SFA) for decision making in waste management. Both MFA and SFA are based on the mass balance principle. While MFA alone has been applied often for analysing material flows quantitatively and hence to determine the capacities of waste treatment processes, SFA is more demanding but instrumental in evaluating the performance of a waste management system regarding the goals “resource conservation” and “environmental protection”. SFA focuses on the transformations of wastes during waste treatment: valuable as well as hazardous substances and their transformations are followed through the entire waste management system. A substance-based approach is required because the economic and environmental properties of the products of waste management – recycling goods, residues and emissions – are primarily determined by the content of specific precious or harmful substances. To support the case that MFA and SFA should be combined, a case study of waste management scenarios is presented. For three scenarios, total material flows are quantified by MFA, and the mass flows of six indicator substances (C, N, Cl, Cd, Pb, Hg) are determined by SFA. The combined results are compared to the status quo in view of fulfilling the goals of waste management. They clearly point out specific differences between the chosen scenarios, demonstrating potentials for improvement and the value of the combination of MFA/SFA for decision making in waste management.
