The fast development of technology and modern branches of industry is conducive to the increase in the amount of generated waste. This is associated with serious ecological and economic problems that must be controlled and solved on an ongoing basis in accordance with the requirements of environmental protection. Early recognition of the threat posed by inappropriate waste management allows to make the right decisions in a short time, which will be safe, acceptable to society and probably associated with much lower costs. Action is needed both by producers and citizens, aimed at developing effective methods of waste disposal. This paper attempts to analyze and explain the issues related to the thermal neutralization of combustible industrial waste. The purpose of the study was to use the abovementioned wastes primarily for energy purposes. This procedure can be applied to various already existing technological processes. Thermal utilization takes place in various types of chambers, and the installations are selected individually for each type of waste due to the variety of their properties.

Currently, the steel industry is facing the problem of the energetic use of process by-products. According to the latest directives, metallurgical gases (COG coke oven gas, BFG blast furnace gas and BOFG converter gas) should not be a side effect that is inconvenient to manage. They should become an energy carrier improving the economic and ecological efficiency of the steel mill. The easiest way to develop them is to burn or co-burn with natural gas directly at the place of production in heating furnaces located in the steelworks. However, this technology faces many difficulties. The biggest technical problems are related to ensuring the required gas purity and continuity of gas supplies with appropriate Energy parameters. Additional difficulties resulting from the nature of the gases burned may ultimately force the user to make the necessary modifications to the way the process is carried out. The consequence of this is the reduction of the economic efficiency of the process.
