The Plastics Market Is Splitting in Two

Commodity polymers face a margin squeeze while certified recycled plastics command growing premiums, reshaping the US chemicals sector

14 Dec 2025

A ton of chemically recycled plastic feedstock cost $730 in 2025, up sharply from the year before. A ton of standard polyethylene, meanwhile, remained under pressure from a flood of Asian supply. The US chemicals industry, in short, is pulling apart at the seams.

On one side sits the familiar commodity business: polyethylene and polypropylene churned out at scale, with margins squeezed by overcapacity built across Asia over the past decade. On the other sits a newer, more lucrative segment: certified recycled polymers, increasingly sought by brands that need to prove their packaging contains documented post-consumer material.

The distinction matters because it is no longer merely voluntary. Maine began requiring minimum recycled content in beverage bottles in 2026. New Jersey has imposed escalating requirements across plastics packaging. These laws convert what was once a marketing preference into a compliance obligation, giving the certified recycled segment something commodity grades have never enjoyed: a regulatory floor beneath its price.

Retail and consumer goods companies are amplifying the effect. Many now require chain-of-custody documentation from their suppliers, meaning a producer cannot simply claim recycled content without verification. This paperwork burden is itself a barrier to entry, and those who have already secured certified circular feedstock supply chains find themselves in a structurally stronger position.

Advanced recycling capacity in the United States is projected to exceed one million tons per year by the late 2020s, as capital flows toward chemical recycling infrastructure. The investment reflects a rational bet: that regulatory and corporate procurement pressure will sustain premium pricing even as the broader polymer market remains soft.

US producers retain one traditional advantage. Cheap ethane from domestic shale keeps their feedstock costs below those of many global rivals, supporting margins where commodity competition is fierce. But that edge alone no longer determines who captures value downstream.

The industry's centre of gravity is shifting. Companies able to certify and sell recycled polymer streams are finding shelter from the commodity cycle. Those that cannot are left competing on cost alone, in a market where Asian rivals have spent years building capacity to do exactly that.
