In the UK, Coca-Cola is supplied with recycled material by a recycling company called Evolve Polyme.
In 2013, a plastic sorting plant under the company was upgraded and put into operation, recycling 6 billion to 9 billion empty beverage bottles each year, and recycling them into food-grade shee.
How exactly does Evolve Polymers do it?
Before the upgrade, the recycled material has reached the "food grade" standard
Before the upgrade, the recycled material has reached the "food grade" standardEvolve Polymers is one of the largest plastic recycling companies in the .
After sorting, cleaning and pelletizing, the recycling plant's recycled plastic pellets are ready for food-grade applications (PurePET78.
However, customers in the UK who use recycled plastics have increasingly higher quality requiremen.
To achieve such a goal, improving the purity after sorting is the key
Coping with "Mission Impossible"
Many of Evolve Polymers' customers have a clear goal to add recycled content to plastic packaging, but must ensure the purity and consistent high quality of the recycled materi.
Raising the quality of recycled plastic to the level of 'bottle-to-bottle' regeneration and supplying UK-based plastic packaging companies with high-quality recycled material for the production of beverage bottles, even for trained waste sorting workers, from It is almost an impossible task to pick out PVC, PC, PS and other impurities from the PET bottle flak.

Specific goals: Specific goals:By identifying and sorting the material and color of the plastic, the purity of the bottle flakes after sorting is significantly improved (the impurity content is reduced to a few parts per million )

face difficultiesEvolve Polymers has introduced 5 sorting equipme.
It can be applied to bottle flake products as small as 2mm to achieve high purity of 'bottle to bottle' recycled material and minimize product loss caused by false rejec.

After the mixed plastic packaging is crushed, cleaned and primary sorted, the final quality control is carried out to control the impurity content in the bottle flakes to the level of several parts per milli.
This milestone achievement resulted in the reduction of the impurity measure from 'percentage' to 'parts per million'
