THE REGULATORY DRIVER

EU End-of-Life Vehicles Regulation (ELVR)

Adopted June 2026 — mandatory recycled-plastic content for newly type-approved vehicles

To comply, suppliers must focus on three pillars:

Material Compliance

Meet recycled-content thresholds, with a minimum share sourced from end-of-life vehicles.

Circular Product Design

Meet recycled-content thresholds, with a minimum share sourced from end-of-life vehicles.

Data & Traceability

Maintain auditable material declarations (IMDS) aligned to ISO 15343.

WHY CO₂E MATTERS

Most of Plastic's Climate Impact Happens Before It's Ever Used

“To keep global warming to no more than 1.5°C, emissions need to be reduced by 55% by 2035 and reach net zero by 2050.”

CARBON FOOTPRINT BY POLYMER

Recycling Cuts CO₂e by 3–7× Across Every Major Polymer

co img

PP: Lowest Footprint

Low chemical complexity and low melting point mean less processing energy — the ideal starting point for recycled composites.

footprint

PA: Highest Footprint

Caprolactam synthesis is energy-intensive — replacing GF-PA with our PCR-PP composite is where CO₂e savings are largest.

From Post-Consumer Waste to Impregnated LFT Pellet

Collect & Shred

PCR feedstock (battery casings, nets, handles) is collected and shredded into flakes.

Density Separation

PCR feedstock (battery casings, nets, handles) is collected and shredded into flakes.

Homogenize & Vent

Extruder melts and homogenizes resin; venting removes volatiles, melt screen removes impurities.

Dry Blend

Uniform PCR-PP granules are dry-blended with stabilizers/compatibilizers for ~30 min.

Melt Impregnation

Blend is extruded at 200–240°C, then fed into the impregnation die at 245°C with continuous glass roving.

Pull & Pelletize

Impregnated strands are pulled, cooled and chopped into ~11 mm LFT pellets.

Skyi’s proprietary manifold and impregnation die design ensures individual glass fibers are fully coated with polymer matrix.

OUR TECHNOLOGY

Restoring PCR-PP to Near-Virgin Performance

We manufacture long-glass-fiber-reinforced polypropylene (LGF-PP) compounds containing more than 40% post-consumer
recycled PP (PCR-PP), using a proprietary functional polymer technology.

Restores Melt Quality

Enhances melt viscosity and consistency of degraded PCR-PP for reliable processing.

Removes Volatiles

Strips volatile content while reacting with low molecular weight chains in the melt.

Automotive-Grade Compliance

Meets VDA 270/271 standards for VOC emissions, fogging and odor performance.

Drop-In Replacement

Replaces GF-PA in interior parts — up to 3× lower CO₂e at comparable performance.

RECOMMENDATION

Which Grade Fits Your Priority?

If Sustainability Is Primary

RX_C24_304_01

67% rPP

  • Highest recycled content
  • Acceptable mechanical properties
  • Small cost reduction vs. reference

If Balanced Performance Is Required

Treei® OH0135.blk

>45% rPP

  • Best overall mechanical performance among recycled grades
  • Highest stiffness & best impact strength
  • Competitive price

If Cost Reduction Is Primary

RX_C24_304_02

50% rPP

  • Lowest cost of all grades tested
  • Performance similar to RX_C24_304_01
  • Good option if impact resistance isn’t

PCR-PP at ~45% Is the Optimum Solution

1

Process advantage

The LFT manufacturing process makes it possible to use post-consumer recycled PP directly, with a pre-processing step for quality and melt-strength additives for stability.

2

Content range achieved

PP-LFT, 20% glass fiber compounds were produced spanning 40–67% recycled content.

3

Most cost-optimum route

Making a higher-glass-content compound in virgin PP, then diluting with recycled PP granules.

4

Recommended grade

Treei OH0135.blk Direct melt-mixed PP-LFT, 20% GF with ~45% PCR-PP, balances handling, moldability, uniformity and long-term aging performance.
