Repsol, Axon and IFPEN introduce new process to enhance chemical recycling of plastic waste

Global technology providers Repsol, Axens and IFPEN, a renowned research and innovation company in the French energy sector, have developed a pioneering patented process that enhances the chemical recovery of plastic waste and promotes circular materials production
.

The RewindTM Mix process removes impurities such as silicon, chlorine, diolefins and metals from the produced plastic pyrolysis oil, allowing the undiluted feed to enter the petrochemical unit directly
.

Pyrolysis is one of the most promising avenues for chemical recycling of plastic waste that would otherwise end up in incineration or landfill and produce food-grade, low-carbon footprint recycled plastic
.

This new pyrolysis oil upgrade process will expand its deployment and allow large-scale introduction of recovered pyrolysis oil into existing steam cracking assets
.

Chemical recycling now represents a very innovative solution, complementing mechanical recycling
.
Petrochemical production of polyolefins accounts for about half of the world's plastic production and is a major target for plastic recycling
.
Currently, mechanical recycling faces limitations as raw material quality (a mixture of polymer and impurity content) directly affects product quality and potential applications (especially food-grade uses)
.

The RewindTM Mix process was developed in the Repsol technical laboratory and IFPEN facility with extensive pilot plant testing of representative pyrolysis oils, reproducing the exact conditions of the industrial plant of the future
.
It can be advantageously integrated into existing petrochemical plants
.

The process relies on Axens' proven industrial technology and catalysts, as well as the long-term experience of three petrochemical industry partners
.
Building on this solid foundation and extensive pilot testing, the partners will now investigate the first industrial applications at the Repsol facility, while Axens will commercialize the technology through a license
