A recycling system has a pyrolysis apparatus (40) having a combustion section (42) for selectively combusting a carbon component in materials, and a gasification section (41) for pyrolyzing and gasifying the materials by using heat of combustion in the combustion section (42). The materials include residual oil from an atmospheric distillation unit (10), a vacuum distillation unit (20), and a decomposition unit (28), various wastes including waste plastics (181), wastes (182), and shredder dust (183), and organic matter such as biomass (184). The recycling system has a passage for supplying pyrolysates (120) produced in the gasification section (41) to an oil refinery system or a petrochemical system. |
