| Abstract | Various types of industrial wastes formed in the Nizhnekamsk industrial hub are considered. Requirements to the development of eco-industrial parks are discussed, and a typical scheme for making decisions concerning setting such parks is suggested. Two types of wastes characteristic for the considered industrial hub are identified, namely: low-tonnage (less than 500 tons per year) and large-tonnage (over 500 tons per year). While assessing qualitative characteristics of waste formation, alternative waste management ways are recognized. The priority attention is paid to petroleum-containing wastes, wastes of rubber technical goods and tires, as well as spent oil wastes. Options for waste processing are considered - of both secondary energy resources and secondary material resources, which are preferable for a circular economy. The following methods of waste processing have been selected: pyrolysis for petroleum-containing wastes; production of rubber crumb and bitumen-rubber composition - for wastes of rubber technical goods and tires; production of refined technical oils for spent oil wastes. Based on the results of the consolidated financial assessment, authors suggest the most feasible solution, namely: the technological scheme with the production of 3 products - rubber crumb, bitumenrubber composition and refined technical oils. It is evident, that at the initial stage, this solution requires investment in capital equipment. The least expensive is the technological scheme with obtaining only purified oil, when other wastes are pyrolyzed. Although this scheme is expected to be less profitable, the authors believe that this scheme should be selected at the first stage of organizing an eco-industrial park. It is demonstrated that in the Nizhnekamsk industrial hub, it would be financially and environmentally optimal developing an eco-industrial park for applying secondary resources in the economic cycle, producing goods using industrial wastes and forming material flows typical for circular economy. |
