The Progressive Policy Institute has released a policy analysis titled "The Waste Diversion Benefits of Expanding Advanced Recycling," framing chemical-recycling capacity as a disposal-avoidance mechanism rather than solely an output-substitution pathway.

The Washington-based think tank's title choice positions the technology in direct competition with landfill volumes, waste-to-energy throughput, and post-consumer export tonnage. That framing carries weight in a regulatory environment where state legislatures, federal agencies, and brand-owner procurement teams are simultaneously redefining what qualifies as recycling.

What does "waste diversion" mean in PPI's framing?

The report's title — "waste diversion benefits of expanding advanced recycling" — anchors the technology to displacement. A tonne processed through pyrolysis, depolymerization, or solvolysis displaces a tonne that would otherwise move through a disposal pathway. That definition lets advocates argue for capacity expansion without resolving the parallel debate over whether chemically recycled output should count as "recycled content" under state minimums.

The framing — diversion rather than recycled-content accounting — fits a wider effort to position advanced recycling as a complement to mechanical recycling, not a substitute for it.

Why does the framing matter for operators?

The diversion lens changes the questions a permitting authority, a brand owner, and a state regulator ask. A facility's diversion claim depends on the counterfactual — what the feedstock would otherwise have done.

• Tonnage baseline: landfill tip fees, WTE gate fees, and export market prices set the displacement value
• Output classification: pyrolysis oil, monomers, and depolymerized feedstocks may be products or residuals depending on jurisdiction
• Permitting pathway: classification as manufacturing versus solid-waste management determines which agency holds authority and which air-emissions standards apply

The classification question matters most. If output counts as a product, the facility operates as a manufacturer. If output is a residual, the facility remains a solid-waste operation with a tighter air-emissions envelope.

Where does this fit in the broader literature?

Industry-funded analyses have quantified advanced-recycling diversion for several years. Trade associations have published tonnage projections, facility-level case studies, and counterfactual baselines. PPI's report is an entry from outside the resin-producer and chemical-recycling developer community into a literature those groups have dominated.

The shift in authorship matters because state legislators and federal rulemakers weight analyses by source. A think tank outside the industry coalition widens the coalition available to advocates. It also shifts the burden of proof: industry analyses face dismissal as self-interested; a non-industry-aligned source does not.

What does the sector still need to see?

The full PPI report will need to publish:

• A stated diversion methodology — tonnes in, tonnes displaced, baseline assumptions
• A sensitivity range around the central tonnage figure
• A clear position on whether chemically recycled output should count toward recycled-content mandates
• An acknowledgement of the limits of advanced recycling relative to mechanical recycling for specific resin streams

Until those elements are public, the report is a frame, not a finding.

What decides what happens next?

The next milestone is not the report itself but how it travels. Watch whether the document appears in:

• State-level recycled-content rulemaking dockets
• Federal comment letters on solid-waste variance petitions
• Brand-owner recycled-content disclosures and sustainability reports
• Trade-press coverage that cites the diversion figures in subsequent facility announcements

The benchmark for "success" is citation, not endorsement. A report that regulators and procurement staff read and reference — even to dispute — moves the policy conversation further than one that disappears into a think-tank archive. PPI's contribution will be measurable not in tonnes claimed but in subsequent rulemakings and corporate disclosures that adopt its framing.
