Selected types of biomass, waste plastics will be thermally processed by pyrolysis to fuel oils, energy gas and solid residue. At the same time, these materials will be processed by a gasification process in a fluidized bed gasifier. A content of sulfur and a higher heating value of heating oils will be characterized. The composition of high hydrogen energy gas will meet the requirements for clean combustion. The solid residue after pyrolysis of biomass will be a suitable intermediate for the production of active coke.
