The environmental accountability of efficiency evaluation of processing technogenic formations

Abstract

This paper considers environmental and economic aspects of inclusion of man-made iron and steel resources. Theoretical approaches to the concept of damage from environmental pollution caused by activities of metallurgical enterprises are investigated, in particular, the problem of disposal. The importance of categories of damage in the development of economic instruments to address environmental problems of industrial waste storage is emphasized. The total damage from pollution is regarded as a synergistic set of economic and environmental damage. Thus, the basic criterion in determining the economic damage appears to be the cost of resources needed to compensate for the damage to the environment - the time required for self-healing of the system. The possibilities of using waste steel from electric melting production as feedstock for the production of zinc are discussed. An assessment of the effectiveness of the investment project to engage in the processing of industrial wastes in Chelyabinsk Zinc Plant is made. The high efficiency of commercial and financial viability of the proposed technology for processing zinc-containing industrial wastes is shown. Calculations are performed to assess the damage avoided as a result of the processing of man-made structures, which is composed of damage prevention and land degradation and damage from pollution by chemicals. It is shown that cost-effective processing of man-made iron and steel resources is essential to address environmental problems of the metallurgical complex.
