PROSPECTS OF MODERN TECHNOLOGIES APPLICATION IN THE CONSTRUCTION WASTE PROCESSING

Cover Page

Abstract


The article presents the innovation of technology of recycling concrete, reinforced concrete and non-ferrous metal scrap, which are by-products of the construction industry.One of the areas of construction waste recycling may be the recycling of electrical cables for the purpose of extracting lead, copper and aluminum. Non-ferrous metals containing electric cables, wires, contacts, etc., are a small volume, but they weigh quite a significant portion of construction waste and can serve as an effective raw material for the production of secondary metals.In the article the authors developed an integrated hydrometallurgical scheme of processing cable scrap, differing from the standard pyrometallurgical methods of high degree of extraction of precious metals in marketable products; possibly containing a purity of 99.99% lead; minimum quality required of copper or aluminum contained in the cable scrap.Another promising direction of recycling of construction waste is proposed the technology of using them as consumable material in the construction of buildings, facilities or structures using 3D printing.Development and implementation of the proposed technologies for processing of construction waste will help solve several important tasks:- reduction of economic costs for disposal of construction waste;- development of new materials with specific characteristics;- reducing the time of processing construction waste;- reducing the harmful effects of construction waste on the environment.
