Results of research on the morphological composition of solid municipal waste in residential buildings in southern regions of Russia

The relevance of the work is determined by the extensive coverage of the «waste reform» in public sources, mass media, and scientific publications. The article provides references to sources confirming the constant changes in the morphological composition of solid municipal waste and its differences based on the source type. The paper presents the results of research on the morphological composition of solid municipal waste in residential buildings in the central regions of the Russian Federation, based on studies conducted from 2016 to 2022. The research was carried out in the Republic of Mordovia, the Republic of Bashkortostan, the Yaroslavl region, and the Tula region at 105 accumulation sites, located in 25 municipalities (urban district, urban or rural settlement). The research results show differences in the composition of solid municipal waste from apartment buildings and individual residential houses in the central regions of Russia. The author draws conclusions about the composition of solid municipal waste for apartment buildings and individual residential houses in the central regions of the Russian Federation. It is determined that the main component of this type of waste is food waste regardless of the type of housing conditions. The main difference in the composition of solid municipal waste from apartment buildings and individual residential houses is the different percentage ratio of the «paper, cardboard» components. Changes in the composition of these waste materials are identified by seasons. It is shown that seven main components of solid municipal waste: food waste, paper, cardboard, garden and park waste, glass, screenings (small fraction, sweepings), miscellaneous, and polymers constitute about 90 % of their total mass.
