The technology of thermal utilization of meat-and-bone meal (MBM) is still at the research state. However, there are already a number of existing pilot-scale installations that provide the complete, effective and environmentally safe process conducting. The universal technology was developed that allows to combust various types of waste, including animal waste, municipal waste and sludge, mixed at any ratio with different types of biomass. It provides the possibility to utilize the waste-and-biomass fuel mixtures of up to 90%wt of moisture content, whilemaintaining the allowable pollutant emission to the atmosphere and soil. This regards mainly NOx, SO2, HCl and VOC. Contrary to the typical large scale grate boilers used for waste incineration, the developed operating pilot-scale plant with a capacity of 12MW offers the complete combustion of animal meal, resulting in a flue gas which is proved to be free of flammable gaseous components and sooty particles in slag and fly ash. The thermal decomposition and combustion of waste using this technology ensuresthermal conversion of chemical energy contained in waste and biomass intothe heat and electricity, while preserving the optimum thermodynamic efficiency of technological system. The efficiency of the prototype installation varied between 88.36 and 84.84% depending on the load.
