In this paper, an ecological and chemical safety assessment of using RDF (Refuse-derived fuel) is considered. It is shown that production and consumption wastes, including combustible unclaimed fractions of secondary material resources from household solid waste, which have undergone preliminary sorting and preparation, in terms of grinding and cleaning from non-combustible inert materials, are used as raw materials for its manufacture. It has been established that it is expedient to use this type of fuel during thermal decomposition (pyrolysis) with a working temperature of about 1200-1500 °C, since at this temperature all substances pass into the composition of flue gases. Installation "Mark 1" is proposed, which can be used in boiler station for burning RDF. The technological scheme and the principle of operation of the proposed installation are described. An assessment of the impact of the operation of this installation on the environment was carried out. It is shown that the concentrations of pollutants from the heating system, according to the protocol for measuring quantitative chemical analysis (QCA) of emissions into the atmosphere at control points at a distance of 25 meters from the mouth of the boiler station pipe, using the example of pilot tests of RDF, do not exceed the MPC. Thus, the ecological and chemical safety of RDF is confirmed and its use in combustion plants equipped with swirling-type furnaces is justified.
