Chemical Recycling versus CuRe Polyester Rejuventation
CuRe Technology an end-to-end recycling process
Together with Cumapol, Morssinkhof and Niaga we have developed the CuRe Polyester Rejuventation Technology, CuRe Technology will focus on providing an end-to-end recycling process for used polyester, rejuvenating it via a partial depolymerisation process into high-quality, ready-to-use rPET which can replace virgin PET from fossil-derived sources. The depolymerization is not going further than necessary for thorough purification and decolourization. In the same process the molecular weight is increased to produce a useful polyester again. An energy-efficient solution for endless product to product transformation. Creating a fully circular polyester chain.
Continuous depolymerisation process
CuRe enables a continuous polyester recycling process for various used and contaminated polyesters - including packaging materials and textile products - and cleans the original polyester material from contaminants and color. 4 Specific type of polyester product streams will be treated: PET trays, Colored PET bottles, Polyester carpet and Polyester textiles.
Mechanical recycling of post-consumer or post-industrial polyester
Mechanical recycling is successful, it works for clear plastics bottles but it still leaves a lot of polyester waste unused. Heavy colored materials and other non-food polyesters are not suitable as feedstock for this process. That is why we have developed this new continuous CuRe Rejuvenation process. It is a new way to recycle polyester (rPET) in a highly profitable and environmentally sustainable way. When done appropriately, the material retains its qualities and the process has minimum byproducts, while we recycle it infinitely, again and again and again. And there is another option: during this CuRe recycling process, bio based monomers could be incorporated into the polymer chain to make it even more sustainable.
Depolymerization recycling technologies complement existing mechanical recycling processes. They have the potential to upcycle difficult to recycle PET that cannot currently be recycled via mechanical recycling means and is instead currently downcycled, incinerated or sent to landfill. CuRe Technology could play a role in significantly increasing the supply of rPET whilst also accelerating the transition to a circular economy for PET by reducing the reliance on virgin oil-based PET.
We will need 2 years developing of the CuRe Technology on the pilot line. After that the existing polymerization lines will be rebuild, this will have a capacity of 25kton/year.
