摘要： The present invention relates to a raw-material supply system and a raw-material supply method for pyrolyzing waste plastic including PVC and PET. The raw-material supply system includes: a slaked-lime supply device (12) configured to feed slaked lime to the waste plastic; an operation controller (15) configured to instruct the slaked-lime supply device (12) to feed the slaked lime to the waste plastic, the slaked lime to be fed having the number of moles that is 1 to 4 times a total number of moles of the polyvinyl chloride and the polyethylene terephthalate in the waste plastic; a melting dechlorination device (18) configured to dechlorinate the polyvinyl chloride and hydrolyze the polyethylene terephthalate by mixing the waste plastic and the slaked lime while heating the waste plastic and the slaked lime; a degassing hopper (20) coupled to the melting dechlorination device (18); and a raw-material supply device (22) configured to deliver the molten waste plastic from the degassing hopper (20) to a pyrolysis furnace (6).
