Title:
CHEMICAL RECYCLING DEVICE AND CHEMICAL RECYCLING MOLDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/014455
Kind Code:
A1
Abstract:
A chemical recycling device 100 is equipped with: a depolymerization reaction tank 300 that degrades a first molded article made of a polymer into a depolymerized product through a depolymerization reaction; a polymerization reaction tank 400 that synthesizes the depolymerized product into a polymer through a polymerization reaction; and a polymer supply part 600 that supplies the polymer synthesized in the polymerization reaction tank 400 to an injection molding machine 1 that molds a second molded article. A byproduct removal device 500 is provided between the polymerization reaction tank 400 and the polymer supply part 600 to remove a byproduct that is generated together with the polymer by the polymerization reaction in the polymerization reaction tank 400.
