The problem of waste management is acute in the Russian Federation. Not enough attention is paid to the systematic studies of their composition and properties. The purpose of the work is to conduct a comprehensive analysis of data on waste generated, to select models for predicting their mass, composition, and properties, to substantiate the feasibility of using exergetic analysis to assess safety and make informed decisions on the management of solid municipal waste management. To predict the volume of waste generation, the following were used: an integrated autoregression model — a moving average and exponential smoothing models. The study of changes in the composition and properties of the municipal solid waste, the choice of technology and the assessment of safety in waste management were carried out using the exergetic method. Its advantages are determined by the possibility of conducting a comprehensive energy-ecological assessment and determining the fire hazard of waste and the processes of handling them. The application of the Holt-Winters model for predicting the mass of the generated waste is substantiated. The analysis of changes in the morphological composition of waste, their distribution by types of economic activity is carried out. The values of chemical exergy of municipal solid waste are determined, and a forecast of its further growth is constructed. The dependences of chemical exergy on the heat of combustion of waste are found. It is determined that it is advisable to consider chemical exergy as a heat engineering characteristic and an indicator of fire and environmental hazard of waste. It is proved that the exergetic efficiency of the incineration process is higher than that of composting and burial. Transportation of garbage from the large cities by road and rail transport for subsequent disposal and recycling can be considered as a forced temporary measure during the development of the branch of industry and the formation of a waste management culture. For the application of the exergy method in the system for ensuring safety when handling solid municipal waste, a data mining system was developed. It is advisable to use the obtained results for the development of safety requirements for the management of production and consumption waste in the Russian Federation.

Abstract A statistical analysis of information about fires that occurred on the railroads shows that it is necessary to enhance the fire protection measures while transporting the fire-hazardous materials (FHM). A comparative analysis of the use of the exergetic index and the flammability potential for forecasting the fire risks connected to the railroad FHM transportation has been performed. The studies considered municipal solid waste (MSW) as promising railway cargo. The values of the MSW chemical exergy and the heat of combustion have been calculated. The conditions and behavior of their variations have been investigated. A system of the substances and materials classification that is based on the exergetic coefficient was introduced. The proposed approach allows us to resolve methodological problems caused by the requirement to account for the technical, economical criteria, and the fire risk indexes into a unified classification system. The conception of the exergetic index improves the objectivity of the procedure for the estimation of the MSW flammability properties.
