Summary

The paper presents technical conditions related to the implementation of component processes of mechanical recycling of thermoplastic materials with a porous structure. Significant influence of the type and form of porous waste on the efficiency of the processes of their cutting, grinding, dosing and also of secondary injection molding process was indicated. It has been shown that by appropriate selection of technical conditions, it is possible to produce molding parts, without the use the holding phase in the secondary injection molding and with complete elimination re-extrusion process.
