Research of trend-seasonal time series in the sphere of recycling of ferrous and non-ferrous metals

Abstract

Purpose: to study of seasonality in the sector of recycling of scrap metal, in particular seasonal fluctuations in the collection of black and non-ferrous scrap. Discussion: subject to the provisions of the development strategy of the metallurgical industry of Russia until 2030, as well as the instructions of the President of the Russian Federation of 23 February 2019 the urgency of economic research in the sector of secondary processing of ferrous and non-ferrous metals. In the context of measures aimed at increasing the collection of scrap in the country, an economic study of the collection of scrap, in particular the study of its seasonal fluctuations, is necessary. The study of the time series of the mass of black and non-ferrous scrap metal using the Chetverikov method. Results: for trend-seasonal time series of scrap weight for four positions – copper, brass, aluminum, ferrous metal, the values of the seasonal component and specific seasonality indices were calculated using the Chetverikov method, which makes it possible to further study, use and predict the collection of scrap metal in the region.
