摘要

This paper analyses the generation of waste in production processes using a technique based on the physical law of conservation of mass. According to this law, mass going into a production process must equal the mass coming out of the same process. The paper uses this mass balance perspective to refine a previously developed technique for forecasting waste quantities. A macro-economic model predicts the use of intermediate inputs and production in monetary units, and by multiplying these variables with weight conversion factors we estimate physical amounts going into and out of production. The difference between input and output, the residual, consists of discharges to land, water and air. We predict a growth in the residuals from manufacturing industries of 74% from 1993 to 2010. This growth is partly explained by an anticipated growth in material intensity.
