Research on the optimization price of the industrial waste based on industrial symbiosis

Currently, many companies face dual pressures of bearing the cost of harmless treatment for industrial waste and the continuous rising of the price of raw materials and energy. In order to solve this problem, many industrial wastes from other companies are purchased to substitute the raw materials or energy, at the same time, it sales the industrial wastes of themselves, so the industrial symbiotic relationship is format between this two companies. In this paper, the transaction price of industrial waste is discussed, which is affected by the production of main products, cost of harmless treatment, cost of transportation and initialization treatment, market price of raw materials to be replaced, the government subsidies for the industrial waste recycling, Etc. A industrial waste transaction price model is constructed to maximize the total symbiotic benefit between the two enterprises formed a industrial symbiosis relationship, and the model solution process and a numerical example is also proposed, which provides a reasonable approach to price the industrial waste.
