Razvoj modela za upravljanje tokovima industrijskog otpada zasnovanog na formiranju eko-industrijskih mreža

Abstract

The Dissertation comprises the development of a new model for regional management of secondary raw materials within the concept of by-product exchange, with the aim to develop a functional eco-industrial network. As a part of the model for industrial waste flow management, a software platform for processing data on secondary materials in the framework of an industrial sub-sector or enterprise network was created. Based on geographic location and the available quantities of required by-products, the optimal location of a new industrial unit (by-product consumer) of a given capacity was determined, in terms of effective supply and/or minimal transportation costs, acknowledging regional sustainability priorities. The main goal of the research was creation of a model for solving the location problem of waste (secondary materials) treatment facilities, taking in consideration the territorial distribution of raw materials, the type and the quantities of raw materials and the distance between the industries, but simultaneously considering regional social, economic and environmental issues. The specific goal of the research was to design an appropriate model and software tool capable of analyzing all relevant industrial plants within an observed region according to the type of required secondary material and the amount of waste they generate, but in context of regional sustainability. Methods of global optimization, i.e. heuristic algorithms were applied to determine the initial location of by-product treatment facility. The limited capacity model of p-median and other similar models were used for initial network optimization. For the final placement of the waste facility, after the initial priority optimization by p-median model, the analytic hierarchy process (AHP) was used as a multi-criteria decision support method of choice for the regional management of industrial waste. Previously, the economic, social and environmental protection criteria were defined as a necessary prerequisite for decision-making during integrated resource planning and preventive mitigation of the impacts that arise in an industrial area and its immediate surroundings. The developed model for industrial by-product flow management, based on eco-industrial network operation principles, constitute a foundation for design of a software tool / a decision support system which might contribute improvement of the current by-product management practices in the region.
