CK Polymers are one of the fastest growing plastic recycling companies in the UK today. We have several plastic recycling facilities and a network of recycling partners across the UK so we can arrange collection of your plastic waste from wherever you are. If you have obligations under the packaging waste directive CK Polymers are accredited for the issue of PRNs.

CK Polymers buy plastic waste for recycling and can also offer recycling processes on a toll processing basis. Below you will find a brief description of our Compounding plastic recycling process.

The compounding process is similar to that of an injection moulding machine. Plastic raw materials and additives are metered into a hopper at one end of a barrel. This material is transported along the length of the barrel by an Archimedes screw and is melted by applying heat from external heater bands, as well as the heat caused by friction / shear heat.

As the material moves along the screw, special sections of the screw knead, mix and compound the plastic, additives and fillers together. At the other end of the barrel, the melted plastic is passed through a wire screen that filters out any residual dirt, grit or other contaminants, and is then pushed through a die plate.

As the material comes through the die plate, it is cut into pellets and then cooled by quenching in water. It is then dried and packed into a selection of different packaging types.
