CK Polymers Ltd are experts in the field of plastic recycling and have facilities and resources across the UK. We provide a range of plastic waste management and recycling services for all plastic types and can help with plastics identification if required.

To aid with polymer identification for plastic recycling purposes, many plastic product manufacturers have taken to marking their products with a plastics identifcation marking system outlined in the table below.

It is not yet a legal requirement to mark plastic products but many manufacturers (perhaps expecting further legislation relating to producer responsibilities in) have taken to using the coding system devised by the American Society of the Plastics Industry to identify larger plastic parts (eg. in cars and electrical goods) and for packaging items.
