How to Reduce EPR Fees with Eco-Modulation
May 9, 2026 · 8 min read
EPR fees aren't flat — they're eco-modulated. The rate you pay per pound depends directly on how recyclable your packaging is. Non-recyclable materials cost 2–5× more than recyclable ones. In states with active fees, switching from non-recyclable to recyclable packaging can cut your EPR costs by 55–81% on rigid plastic and 25–58% on flexible film.
This guide shows exactly how eco-modulation is built into each state's fee structure — with real numbers from published rate schedules — and gives you 7 concrete strategies to reduce what you owe.
What is eco-modulation?
Eco-modulation means the fee per pound varies by material category. Packaging that's easy to recycle (PET bottles, corrugated cardboard, aluminum cans) pays a low rate. Packaging that's hard to recycle (multi-layer laminates, PVC, mixed-material pouches) pays a much higher rate. Some states also apply additional credits (fee reductions) or maluses (surcharges) on top of the base rates.
The result: two brands with identical packaging tonnage can pay very different fees depending on their material choices.
How eco-modulation differs by state (2026 published rates)
- Colorado — Base rates already reflect recyclability. Additional passive factors: Detriments malus (+5%), Not-on-MRL pricing tiers (materials not on the Minimum Recyclable List pay more), High Recycling Rate Bonus (−5%). Active incentives still TBD.
- Oregon — No defined fee adjustments. Reductions are factored into fees based on environmental performance and impact. Qualifying activities: increasing PCR content, reusable packaging, moving to lower-impact materials. SIM = $0.00/lb for 2026, likely to increase in future years.
- California — Illustrative rates reflect recyclability tiers. No eco-modulation factors published yet; expected with program plan Oct 2026.
The rate structure IS the eco-modulation
The biggest lever isn't a separate credit — it's the rate gap between recyclable and non-recyclable materials baked into every published fee schedule. Here's what the actual published rates show:
| State | Recyclable rigid | Non-recyclable rigid | Savings |
|---|---|---|---|
| Colorado | $0.14–0.32/lb | $0.43–1.72/lb | 67–81% |
| Oregon | $0.09–0.50/lb | $0.57–1.38/lb | 64–84% |
| California | $0.11–0.40/lb | $0.17–1.48/lb | 35–73% |
Savings = choosing recyclable over non-recyclable within the same material type (rigid plastic). Rates from CAA 2026 fee/dues schedules and CA illustrative fees. Use the calculator for your specific numbers.
7 strategies to reduce your EPR fees
1. Material selection — pick a lower-fee category
Switching from a high-fee material category to a lower-fee category saves more than any eco-modulation bonus. Non-recyclable materials (laminates, PVC, mixed-material packaging) cost 2–5× more per pound than recyclable ones (PET, HDPE, corrugated). Switching to recyclable rigid plastic saves 55–81% on rigid plastic and 25–58% on flexible film depending on the state.
Applies to all states with active fees (CA, OR, CO) — rate structure rewards recyclability
2. Design for recyclability
Remove problematic laminations, foils, adhesives, and coatings that push packaging into non-recyclable categories. Chip bags with foil + plastic layers, jars with plastic-lined metal lids — these are classified as non-recyclable and get hit with the highest rates. Even small design changes (switching to water-based adhesives, replacing foil lamination) can shift a package from non-recyclable to recyclable, dropping the per-pound rate dramatically.
Applies to all states with active fees — especially CO (MRL pricing tiers apply)
3. Lightweight your packaging
EPR fees are calculated per pound of packaging sold. Less weight = fewer pounds reported = lower fees. A 10% weight reduction = 10% fee reduction — a direct 1:1 savings with no eco-modulation needed. Thinner walls, lighter closures, smaller mailers — every pound eliminated saves proportionally across all states.
Applies to all states — direct 1:1 savings regardless of eco-modulation
4. Increase PCR content
Higher post-consumer recycled (PCR) content shifts packaging into lower-rate recyclable categories and supports impact-reduction claims. Colorado's published dues schedule includes a High Recycling Rate Bonus of −5% for materials with proven high recycling rates. Oregon's environmental performance incentives recognize PCR increases as a qualifying activity. Increasing PCR now also future-proofs packaging for upcoming state programs.
CO: −5% High Recycling Rate Bonus published | OR: qualifying activity under environmental performance | CA: anticipated with program plan Oct 2026
5. Reuse & refill systems
Potentially the largest eco-modulation incentive, but also the most difficult to implement. Oregon's approved program rewards transitions from single-use packaging to reusable/refillable systems. California requires at least 10% of source reduction from reuse/refill or elimination. Best suited for high-volume SKUs where infrastructure investment pays off — household products, beverages, CPG.
OR: qualifying activity for environmental performance incentives | CA: counts toward source reduction mandate | CO: active incentives still TBD
6. Avoid Detriments list materials (Colorado)
Colorado's published dues schedule includes a Detriments malus of +5% — an automatic surcharge on materials that disrupt recycling processes. If your packaging includes materials flagged as detrimental (like PVC, additives that contaminate recycling streams), you pay 5% more on top of the already-higher non-recyclable base rate. Oregon and California have not yet published similar lists for 2026.
CO: Detriments malus +5% published | CA & OR: not yet published
7. Avoid Prop 65 chemicals (California)
California's SB 54 is expected to include a malus for packaging containing chemicals listed under Proposition 65 (PFAS, vinyl, etc.). The specific surcharge percentages have not yet been published — CAA is expected to release them with the program plan in Oct 2026. Removing these chemicals now prepares you for when the malus takes effect and helps comply with other CA regulations.
Applies to: California (SB 54 — specific malus TBD)
How to get started
- Audit your packaging — inventory every SKU, material type, and weight category. You can't optimize what you haven't measured.
- Check your obligations — Am I Covered? tells you which states require you to register in 60 seconds.
- Estimate your current fees — Use the calculator to get a baseline for what you'll owe today.
- Model eco-modulation savings — switch materials in the calculator to see how different choices change your bottom line.
- Prioritize high-impact swaps — focus on converting your highest-volume non-recyclable SKUs first for the biggest fee reduction.
The brands that start optimizing for eco-modulation now will pay significantly less when full fee structures kick in across all seven states. Those that wait will pay the highest rate tiers — and face years of compounding costs.
