PET recycling

The recycling PET process

MacDermid Chemicals are a vital component in the recycling PET process. PET (PolyEthylene Terephthalate) is a strong but lightweight material used to make containers for drinks, personal healthcare and other food and non-food applications. PET is fully recyclable.

Typically after collection the used containers are washed to remove labels and residues, ground into flake then sorted (by floating / sinking) to remove other plastics such as polypropylene and polyethylene.

It is at the washing stage that MacDermid chemicals are used to aid the recycling process:

cleaners and additives

Cleaners and additives to remove glues, labels and organic residues.

Dedicated formulations for different washing technologies, strong foam control properties with a wide range in temperature application.

Enhancing plastic separation

We provide different technologies which enhance the separation of PET from other light plastics.

Our products have inherent foam control properties and the capacity to neutralise the alkaline drag-out.

Defoamers and antifoams

MacDermid PET antifoam technology incudes a wide range of chemical bases which are designed and optimized for each application specific needs.

Cleaning solution reconditioning

Additives dedicated to reduce the suspended solid and COD pollution into washing and prewashing solutions. These specialty products do not interfere with the effectiveness of the organic cleaner additives.

Equipment maintenance

Inhibited descaling products for periodic internal plant maintenance. Our products are specific to remove both alkaline and hardness scale from stainless steel structures, internal pipes and the vibrating screens.

coating strippers

Booster water soluble solvent additives to enhance the solution stripper properties. The removal of coating or paints from plastic substrates.

HDPE/PP or other plastics

Cleaners and additives dedicated to the recycling stream of other plastics like HDPE or PP. Suitable for generic uses or food contact applications
