Abstract

Solid industrial waste can be widely used in construction to obtain such valuable materials: as a filler and binder for the production of concrete, dry building mixtures and other building materials, for the production of building materials with protective properties against electromagnetic radiation and static electricity, for the manufacture anode earthing switches, etc. Therefore, the determination of the regression dependence describing the dynamics of the generation of construction and demolition waste in Vinnytsia region to solve the problem of solid industrial waste management is an urgent scientific and technical problem. The aim of the study is to determine, using regression analysis, the dependence that describes the dynamics of construction and demolition waste generation in Vinnytsia region to solve the problem of solid industrial waste management. The study used the method of regression analysis of the results of one-factor experiments and other paired dependencies with the choice of the best type of function from the 16 most common options according to the criterion of the maximum correlation coefficient. The regression was carried out on the basis of linearizing transformations, allowing reducing the nonlinear dependence to linear. The determination of the coefficients of the regression equation was carried out by the least squares method using the developed computer program "RegAnaliz", protected by a certificate of registration of copyright for the work. Adequate regression dependence was obtained that describes the dynamics of construction and demolition waste generation in Vinnytsia region. A graphical relationship has been built that describes the dynamics of construction and demolition waste generation in Vinnytsia region and allows to visually illustrate this dynamics, to show sufficient convergence of theoretical and actual results. It was found that in Vinnytsia region during the period of 2014—2018 the formation of a mass of waste from construction and demolition decreased hyperbolically. Such a mass of construction and demolition waste generation in Vinnytsia region in 2025 is predicted — 331 tons, and in 2030 — 223 tons
