The problem of developing an optimal waste management system is very relevant in many countries. To solve it, it is necessary to study the processes of waste accumulation, to systematize the factors and conditions that affect the generation of waste, to determine the features of establishing waste accumulation standards for various objects. The article discusses the features of the accumulation of municipal solid waste and the establishment of standards for their accumulation for stationary objects of the distribution network.The volume and mass values of daily indicators of accumulation of MSW from a trading area of a certain type and the total value of accumulation indicators (over the entire trading area) are found. The formats of retail facilities with the maximum average daily indicators of MSW accumulation have been established. Standards for the accumulation of MSW for the category under consideration have been established for 1m2 of retail space with food products, 1m2 of retail space with non-food products.

The technological process of coloured calcium silicate brick differs from the usual manufacturing of white calcium silicate brick by additional emissions of harmful substances in the form of dust of colour pigments. The given article considers the properties of dust particles emitted into the working zone air in the manufacturing shops of coloured bricks, the harmful properties of the dust that negatively affect human health, as well as the potentially hazardous properties of these substances that may lead to tragic consequences caused by explosions or fires.
