Abstract

The invention relates to a plastic waste recycling process and can be used to produce different polymer products.The process, according to the invention, comprises the separation of polyolefins from the rest of waste plastic, pre-grinding of polyolefins and the rest of waste plastic to a size of about 50 mm and fine grinding to a size of 0.5…10 mm. Finely ground polyolefins and the rest of waste plastic are mixed in the ratio of (0.1…0.5):(0.5…0.9) parts by weight, respectively, afterwards there follows the homogenization and transportation of the obtained mixture at a rate of 0.2 m/s in an extruder, plasticization of the mixture at a temperature of 180…210°C to the production of a homogeneous mass, which is subjected to calibration, compression and molding.The proposed process allows of realizing an economical process without preliminary preparation of raw material (washing, drying), without environmental pollution with rinsing water and volatile gaseous waste.
