Abstract:Based on analysis of the relationship between industrial solid waste management and industrial process, framework and method for life cycle management of industrial solid waste which integrate the source reduction process was presented. A case study of copper slag management was conducted with this method. The environmental burden of three scenarios for copper slag management was 2800.46 Pt, 2156.00 Pt and 2162.04 Pt, respectively. Although Flash Smelting could promote reduction of copper slag compared with Bath Smelting, it did not relieve the gross environmental impacts in the whole life cycle of fine copper production and copper slag management. In consideration of slag closed-loop recycling process, environmental performance of Floatation Approach excelled that of Electric Furnace Impoverishment when treating the same quantity of copper slag. The case study proved that it is necessary to integrate the reduction process into the whole life cycle of industrial solid waste and make an integrated assessment of industrial solid waste management scheme, rather than to follow priority and hierarchy simply.
