 The object of research is the processes of plasma-steam-oxygen gasification of hazardous waste using the example of sewage sludge of aeration stations and rubber crumb of worn tires. The purpose of the work is to obtain quantitative indicators regarding the energy efficiency of hydrogen production processes using the example of certain types of waste. The methods of obtaining hydrogen from carbon-containing waste belong to a kind of dual-use technology, because in addition to the ecological effect, they ensure the production of hydrogen according to the principle "greener than green". A cycle of experimental studies and thermodynamic calculations of the process of gasification of a mixture of sewage sludge and rubber crumb of worn automobile tires was carried out, which indicate the prospects of commercialization of technologies for processing such hazardous waste (world level of research). This work explores ways to increase the energy efficiency of hazardous waste recycling processes, with the implementation of the "waste-to-energy" process in mind. It is shown that for plasma-oxygen gasification, the final dependences for thermal energy, which is released in the reactor due to the chemical reaction of gasification of raw materials, and for the chemical energy of the obtained synthesis gas, have universal linear dependences on the amount of oxygen that is introduced into the process.
