Abstract:
From the very nature of mineral raw materials arises the need for its complex processing. Therefore, the fullest possible use of raw materials is possible only when several processing enterprises are merged into a single structure. Consequently, for the rational use of raw materials it is necessary to create territorial inter-sectoral production associations consisting of enterprises of different industries. When this occurs, a connection into a single complex of productions of various industries, representing either successive stages of processing raw materials (for example, smelting iron from ore and conversion of iron into steel, and then, perhaps, the production of certain finished products from steel), or having a supporting role in relation to each other (for example, processing of by-products, production of packaging items, etc.). The integrated use of available resources by combining various industries allows the use of waste from one production as feedstock for another. The regional approach to the processing of material and energy resources helps to reduce the loss of raw materials, materials, energy, reduces transportation costs and labor costs, expands the range of products made from the raw materials used. The creation in the region of combined production and ¬ economic systems, including a group of enterprises of various industries, necessitates the formation of a common technological chain. In this case, it is possible to develop regional technology, which is a combination of technologies of individual industries located in a given territory and interconnected with the task of maximizing the use of raw materials with the lowest costs.
