INDUSTRIAL SYMBIOSIS AND INDUSTRIAL WASTE MANAGEMENT IN WOOD-BASED INDUSTRIES

Abstract

This work is an attempt to study Hayatabad Industrial estate with the objective to identify and evaluate groups of industries for Industrial symbiosis. For this purpose, a questionnaire was conducted among 15 industries. Furthermore, 11 industries were observed personally for their manufacturing process to know about raw material, by products, waste material and its utilization in another industry as input. Wood-based industries, selected for industrial symbiosis include match, chip-board, paper and mold. Their respective solid waste generation rates were 45-50 tons, 30-35 tons, 2-3 tons and 1.5-2 tons/day. This waste is inter-changeable, but woodwaste is generally sold to outside and used as a fuel. If the wood-waste of match industry is used as an input in chip-board and paper industries, demand for fresh wood will decrease by 10% and 90% in chip-board and paper industries respectively. Moreover, utilization of this woodwaste will decrease the energy in these industries by 10% and 20% respectively. Due to lacking of industrial symbiosis, there is not only wastage of resource but contributes the pollution level also. It is therefore required to seek ways and means for efficient industrial symbiosis.
