Environmental impact assessment model for manufacturing processes

摘要

Environmental work in industry is considered as a strategically important issue. This is mainly driven by the social concerns about environmental impacts on human health and ecological system. A number of methods for the evaluation of environmental impacts have been proposed, but heir considerations have only been given to either human health or ecological health. This paper presents a model to evaluate the potential environmental impacts on both ecological and human health of a manufacturing process. Five impact groups are used as the basis for the computation of the hazard values of ecological health. On the other hand, the hazard values of human health are based on the toxicological, cancer and physical effects of waste components. The model has been developed into a computer software, and its effectiveness has been demonstrated by a case of manufacturing process.
