PET’s price crash shows how fragile U.S. recycling really is — and MRFs are holding the bag

The PET market didn’t just soften — it buckled. That swift reversal, and the scramble it triggered at MRFs, is a reminder that U.S. recycling still runs on a brittle business model: volatile commodity exposure strapped to fixed operating costs. As Resource Recycling reported, Circular Services president Joaquin Mariel used PET’s rapid market erosion to illustrate how quickly infrastructure can unravel when one keystone material loses value. Our angle is simple: if you run a MRF or a hauling operation tied to revenue-share contracts, you either build in shock absorbers or you eat the shock.

How fast a core stream can unravel

Resource Recycling’s coverage of Mariel’s remarks lays out the uncomfortable truth: PET looked stable until it didn’t. A cocktail of cheaper virgin, shifting import dynamics, packaging changes, and contamination pressure pushed PET bales from profit center to problem child in a matter of months. Once bale values crater, the ripple effects are immediate on the floor:

• Sort priorities get reshuffled and overtime creeps in to keep quality up for increasingly picky buyers.
• Thermoform PET, already a headache, becomes orphaned unless you’ve carved out a dedicated spec and offtake.
• Inventory balloons because the next buyer down the line has their own glut — raising fire risk, insurance scrutiny, and cash tied up on the pad.
• Municipal partners suddenly question program optics when their "recycling" line item goes from rebate to fee.

Mariel’s point, as conveyed by Resource Recycling, is that scaling infrastructure is hard not because we lack know-how, but because the economics can flip faster than capital and contracts can adapt.

Scaling is hard by design: capex, policy patchwork, and market whiplash

Resource Recycling notes Mariel’s broader critique: building resilient recycling capacity in the U.S. is structurally difficult. The reasons are familiar to anyone who has ever had to justify a new line or a secondary optical sorter:

• Capital is patient only when offtake is locked. But bale buyers and reclaimers avoid long commitments in volatile resin markets.
• Policy is a patchwork. Recycled-content mandates in places like California help, but uneven demand signals elsewhere keep national buyers on the fence.
• Permitting and siting remain slow, so by the time a project stands up, the market cycle may have turned.
• Contamination is still the tax on everything — it erodes yield, eats labor, and widens the gap between spec and reality.

When PET sagged, those structural frictions meant MRFs couldn’t pivot quickly. If your business counted on PET to subsidize the rest of the line, the subsidy just vanished — but the payroll, leases, and utility bills didn’t.

What operators can do now: contracts, quality, and inventory discipline

Waiting for the next legislative fix or brand pledge isn’t a plan. Operators have levers:

• Rework revenue-share deals with municipalities to include transparent index floors, contamination bands, and fee-for-service triggers when commodities fall below agreed thresholds.
• Lock offtake where possible with volume and spec commitments tied to published indices, and insist on quality feedback loops (QC photos, inbound lab data) to cut disputes and rejections.
• Treat PET thermoforms as a separate product with its own spec. Mixing them into bottle bales when markets are weak just dilutes everything.
• Invest in yield and quality before tonnage: secondary optical sorting on small containers, better label/glue management, and moisture controls can maintain access to the few buyers still paying.
• Manage inventory like a risk asset. Set hard aging limits, diversify buyers regionally to reduce trucking exposure, and avoid “just one more stack” that becomes a months-long stockpile.
• Coordinate with haulers on route education when you tighten specs. If you’re turning away loads for moisture or glass fines, the fastest fix is at the curb, not at the drumbeat meeting after three rejections.

None of this makes PET prices go up. It does make the business survivable when prices go down.
