Title:
METHOD FOR RECYCLING WASTE PLASTIC BY USING SUBCRITICAL HYDROTHERMAL TREATMENT
Document Type and Number:
WIPO Patent Application WO/2023/068385
Kind Code:
A1
Abstract:
The present invention relates to a method for recycling waste plastic by using subcritical hydrothermal treatment. According to the present invention, it is possible to manufacture recycled plastics by using, as main materials, used plastics, fibers, rubbers, or plastic dust that cannot be reused due to difficulties in separating and sorting and that have been incinerated and landfilled, to reduce the proportion of use of polypropylene or polyethylene by mixing the recycled plastics with a recycled polypropylene and/or recycled polyethylene raw material, and to produce recycled plastic pellets with properties suitable for specific applications, for example manufacturing a car stopper.
