The Maine fee formula
Every Maine LD 1541 fee a producer pays comes out of a formula similar to other US state EPR programs but with one important wrinkle: Maine's per-ton rates are calibrated to what Maine municipalities actually spend to manage that material, not to a PRO's operating cost.
Fee = (tons of covered material) × (base rate for that material) × (1 ± eco-modulation factor)
Base rates by material category
Maine sets base rates per metric ton for each material category. The categories largely follow the standard sweep used in other US programs:
- PET, HDPE, aluminum, steel, clear glass, and uncoated papergenerally lower base rates.
- PP, mixed plastics, coated paper, and colored glassmiddle of the pack.
- Multilayer plastic films and laminatesamong the highest base rates because Maine MRFs cannot recover them economically.
Exact 2026 base rates vary by cycle; verify against the current Maine DEP and stewardship organization rate sheet before quoting numbers to your finance team.
How Maine's recyclability tiering works
Maine assigns each material category to a recyclability tier based on whether it can actually be recovered by Maine's collection and processing infrastructure. The tier directly drives the per-ton rate. Materials in the most recyclable tier pay the lowest base rate; materials that Maine MRFs cannot recover pay the highest base rate.
This tiering matters because two materials that look chemically similar can sit in different tiers if one is recovered in Maine and the other is not. Two tier examples:
- Clear PET bottles typically sit in a high-recyclability tier and pay a low base rate.
- Black PET thermoforms often sit in a much lower-recyclability tier and pay a higher base rate, even though both are PET, because dark pigments defeat optical sorting and the material does not get recovered in practice.
The lesson: recyclability under Maine's program is operational, not theoretical. Whether a material is technically recyclable is less important than whether it actually gets recycled in Maine.
Eco-modulation in Maine
On top of base rates, Maine applies eco-modulation factors:
PCR content discount. Verified post-consumer recycled content reduces the fee. The discount typically scales with verified PCR percentage up to a cap.
Design penalties. Maine penalizes designs that contaminate recycling streams: PVC labels on PET, dark pigments below the optical-sortability threshold, mixed-material laminates, attached non-recyclable closures, and adhesives that defeat fiber repulping.
The modulation factor stacks on top of the tier. A virgin PET bottle in the highest-recyclability tier with a PVC sleeve label pays the low base rate plus the design penalty. A 50% PCR PET bottle in the same tier with a clear PE label pays the low base rate minus the PCR discount.
Worked example 1, Beverage producer with PET bottles
A beverage company places 800 metric tons of PET bottles into Maine in 2025. Bottle composition: 30% PCR, clear PET, PE label, PE closure.
- Tier: high recyclability (clear PET, PE label).
- Base: 800 t × low PET base rate.
- PCR discount: 30%.
- No design penalty.
Estimated annual Maine EPR fee: low base × 800 × (1 − PCR discount factor at 30%). Substitute the current Maine rate sheet to produce a dollar figure.
Worked example 2, Snack brand with flexible film pouches
A snack brand places 150 metric tons of multilayer plastic film pouches into Maine. Composition: PET-PE-foil laminate, no PCR, dark pigments.
- Tier: lowest recyclability (multilayer laminate, dark pigments).
- Base: 150 t × highest film base rate.
- PCR discount: 0%.
- Design penalty: yes, multilayer laminate and dark pigments.
Estimated annual Maine EPR fee: high base × 150 × (1 + design penalty factor). For most snack brands, this single SKU family is one of the largest line items in their Maine compliance budget and a top redesign priority.
Worked example 3, Spirits brand with glass bottles
A spirits brand places 300 metric tons of clear glass bottles into Maine. Composition: 25% PCR cullet, paper label, aluminum closure.
- Tier: high recyclability (clear glass).
- Base: 300 t × low glass base rate.
- PCR discount: 25%.
- No design penalty.
Estimated annual Maine EPR fee: low base × 300 × (1 − PCR discount factor at 25%). Glass producers often pay less per ton but face larger absolute weight.
What drives the biggest savings in Maine
Across modeling exercises, three levers move Maine fees the most:
1. Switching multilayer flexibles to recyclable mono-material structures when product format allows. 2. Increasing verified PCR content on rigid containers to capture eco-modulation discounts. 3. Removing design contaminantsdark pigments, PVC labels, non-recyclable closures.

How Packgine handles Maine fee modeling
Packgine ingests SKU-level packaging data, classifies every material against Maine's recyclability tiers, applies the current rate sheet and modulation curves, and produces a fee model for the current cycle and a forecast for redesign scenarios. The same model runs every other US state and the EU.
