MATERIAL FLOW ANALYSIS OF TECHNOLOGICAL CHANGE AND ECO-INDUSTRIAL DEVELOPMENT IN STEEL PRODUCTION INDUSTRY USING WASTE INPUT-OUTPUT MODEL

Abstract

In this paper, Waste Input-Output analysis to focus on the advanced loop-closing technologies in the steel production was exercised to evaluate the material flow and environmental loads due to the technological changes; several scenarios were designed to develop the industrial eco-system through the introduction of an advanced loop-closing technology, which utilizes the industrial wastes as a natural resource substitute, and the reduction of natural resources input and the improvement of resource productivity were identified.
