Chemical recycling projects promoted as a fix for the plastics waste crisis are folding across Europe and the United States, according to a report from The Cool Down.

The publication frames the change bluntly: chemical recycling was billed as a plastics fix, and projects in Europe and the US are now shutting down. The reversal speaks directly to an industry that has spent years pitching advanced recycling as the answer to plastic streams mechanical recyclers cannot process.

What do the closures mean?

The Cool Down's headline does not enumerate plant closures, name operators, or separate pilot units from commercial facilities. That distinction matters. A wave of pilot decommissionings tells one story about scale-up risk; a series of commercial-scale shutdowns tells another about commercial viability.

The cross-continental footprint — failures reported across both Europe and the United States — points to structural rather than regional causes. Feedstock economics, offtake pricing, and recycled-content accounting rules are common denominators across both markets.

What did the pitch promise?

The chemical-recycling pitch centered on converting mixed, contaminated, or multilayered plastic into pyrolysis oil, monomers, or other chemical feedstocks that could re-enter petrochemical supply chains. Operators built that pitch into offtake agreements, recycled-content claims by consumer-goods companies, and submissions to regulators drafting mass-balance accounting rules.

Closing facilities undercut each of those threads. Offtake contracts rely on throughput that is no longer available. Recycled-content claims backed by chemical-recycling output now rest on a smaller operating base. Policy submissions pointed to a build-out that is contracting rather than expanding.

What milestone decides what happens next?

Two regulatory milestones will frame what happens after the closures.

EU authorities finalising accounting rules for how recycled content can be claimed under the Packaging and Packaging Waste Regulation will set the value of existing offtake agreements and the credibility of unbuilt capacity certificates.

US state extended producer responsibility programmes moving into fee-collection phases will set gate prices against which chemical-recycling economics must compete with mechanical recycling, reuse systems, and reduction measures.

Quarterly disclosures from publicly listed operators, bankruptcy filings from venture-backed chemical-recycling companies, and any repurpose announcements for affected sites will provide the next data points.

The Cool Down's report lands as trade-press observers have warned the gap between announced and operating chemical-recycling capacity is widening. Plant closures across two continents suggest that gap is now closing through attrition rather than commissioning.
