METHOD FOR MANUFACTURING RECYCLED PLASTIC
Abstract: provided is a method for manufacturing recycled plastic (b) from a plastic laminate (a) using an extrusion device having a melting and kneading unit in which a screw is disposed and an ejection unit. the method includes: supplying a plastic laminate (a) to the melting and kneading unit of the extrusion device; melting and kneading the plastic laminate (a) supplied to the melting and kneading unit with a screw rotation number 50 to 900 rpm to form a recycled resin composition (a); and ejecting the recycled resin composition (a) from the ejection unit and cooling the same to obtain recycled plastic (b). the plastic laminate (a) has at least a first resin layer, an adhesive layer and/or a printing layer, and a second resin layer. the content of a polyolefin resin is 80 mass % or more with a total mass of the plastic laminate (a) as a reference.
