The European Commission's Joint Research Centre (JRC) has narrowed its chemical recycling assessment to pyrolysis and omitted depolymerization, gasification, solvent-based and enzymatic pathways already operating across several EU member states, according to a Plastics News analysis.

The commentary targets the JRC's methodology for evaluating advanced recycling. Pyrolysis — the thermal cracking of plastic waste into a feedstock usable in steam crackers — has dominated industry announcements and investor coverage of chemical recycling for the past five years. Plastics News argues the JRC report centers on mass-balance accounting for pyrolysis-derived oil as a substitute for virgin naphtha, and gives limited quantitative treatment to other chemical recycling routes.

What does the JRC report cover?

The JRC assessment, which feeds into European Commission work on plastics circularity, evaluates chemical recycling as a complement to mechanical recycling. Its analytical choices directly influence the implementing methodology for the Packaging and Packaging Waste Regulation (PPWR), agreed politically in 2024.

The PPWR sets mandatory recycled-content thresholds for plastic packaging and obliges the Commission to set the calculation rules for chemically recycled output through implementing acts. Plastics News argues that a pyrolysis-centric JRC methodology risks skewing those rules against depolymerization, gasification, solvent-based and enzymatic outputs.

Which pathways does the critique say are missing?

Plastics News identifies four chemical recycling technologies that fall outside the JRC's main analytical frame:

• Depolymerization — chemically breaking specific polymers back into monomers for re-polymerization
• Gasification — converting mixed plastic waste into syngas for downstream chemical production
• Solvent-based recycling — selective dissolution and recovery of polymers from contaminated or multi-layer streams
• Enzymatic recycling — biocatalytic depolymerization, primarily applied to PET

Each pathway has operators at industrial or pre-commercial scale inside the EU. The Plastics News commentary argues that underweighting them in the JRC's mass-balance framework narrows the technical evidence base the Commission draws on for recycled-content rules.

Why does the framing matter for EU policy?

The Commission's choice of recycled-content accounting methodology will shape plant investment decisions, offtake agreements and corporate procurement. Industry groups have lobbied for mass-balance accounting favorable to pyrolysis oil; environmental organizations have opposed it on grounds that mass-balance overstates actual recycling rates.

A methodology that treats pyrolysis-derived output more favorably than depolymerization or gasification output would tilt new project economics toward pyrolysis plants already announced and away from alternative chemical recycling capacity under construction. Conversely, a methodology that credits monomer recovery and syngas-to-monomer routes on equivalent terms would broaden the field of viable projects.

National permitting decisions under the Industrial Emissions Directive also reference JRC technical work, so the report's framing reaches beyond the PPWR implementing methodology into plant-level permitting across the EU.

What milestone decides what happens next?

The next regulatory checkpoint is the European Commission's adoption of implementing acts under the PPWR, scheduled for 2025-2026. Those acts will codify how chemically recycled output — including pyrolysis oil, depolymerization monomers and gasification syngas products — counts toward the PPWR's recycled-content thresholds.

Operators with depolymerization or gasification capacity in construction or commissioning will be watching for a methodology that recognizes their outputs on equivalent terms to mass-balance pyrolysis oil. The Plastics News critique is the latest industry submission pressing the Commission on which technologies its recycled-content framework recognizes and on what conversion factors.

Until those implementing acts land, the JRC report's analytical scope continues to shape Commission technical guidance and corporate recycled-content procurement strategies across the European plastics value chain.
