Summary Acid rain remains an important environmental problem. The Chinese steel industry is becoming a key domestic emitter of sulfur dioxide (SO 2 ), the central molecular component of acid rain. In this study SO 2 emission potential is assessed by developing a material flow analysis (MFA) model and generating four different SO 2 industry emission scenarios from 2006 to 2030, with each scenario representing a possible develop...

Summary Environmental problems are closely related to society' processing of materials through the entire economy. Because neither traditional environmental nor economic analytical methods can provide sufficient insight into the physical dimension of economies, this article presents an integrated methodology, combining a substance flow analysis (SFA) approach and an ecological restructuring analysis. This approach is applied t...
