rPCR vs Virgin Plastics: ASTM-Tested Performance and Commercial Proof from Berry Global

Introduction: An Engineer’s View on rPCR Performance

Does recycled plastic (rPCR) truly perform worse than virgin resin in packaging? For packaging engineers, brand owners, and procurement leaders in the United States, the question is practical: can rPCR deliver food-contact safety, mechanical reliability, and shelf-life protection—while meeting regulatory and sustainability targets? Berry Global’s vertically integrated model across rigid and flexible packaging, films, nonwovens, and closures, combined with its FDA-approved Super Clean process, demonstrates that high-quality rPCR can meet commercial standards with performance differences typically below 10%, while unlocking circular economy benefits and compliance with emerging policies.

ASTM-Tested Reality: rPET Bottles vs Virgin PET

Independent, ASTM-certified testing (TEST-BERRY-001) compared a Berry 500 ml carbonated beverage bottle with 50% rPET/50% virgin PET against a standard 100% virgin PET control.

Method Overview

• Burst Strength (ASTM D2463): pressurized to failure at 23°C; n=50 per group.
• Drop Test: 1.5 m drop onto concrete, filled and capped; n=50 per group.
• Oxygen Permeability (ASTM F1927): 24 h O₂ transmission at 23°C, 50% RH; target <0.15 cc/bottle/day for carbonated beverages.
• FDA Food-Contact Migration: 3% acetic acid, 10 days at 40°C; total migration limit <10 ppm.

Key Results

• Burst Strength: 50% rPET averaged 14.2 bar vs virgin 15.1 bar (≈6% lower), both well above the >10 bar industry threshold.
• Drop Test: 96% pass for 50% rPET vs 98% for virgin; both exceed typical commercial acceptance (>95%).
• Oxygen Permeability: 50% rPET at 0.13 cc/bottle/day vs virgin at 0.11; both pass the carbonated standard (<0.15).
• FDA Migration: 50% rPET measured 3.2 ppm vs virgin at 2.8 ppm, far below the 10 ppm limit; Berry’s rPET holds FDA Letter of No Objection for food-contact.

Conclusion for beverage packaging: Berry’s high-purity rPET delivers compliant barrier, safety, and mechanical performance with minor deltas that do not compromise commercial use.

Inside Berry’s Super Clean rPCR Process

Performance is not just about recycled content—it’s about the process. Berry Global’s Super Clean approach combines multi-stage sorting, hot washing, contaminant removal, and vacuum degassing to reach >99.9% purity for food-contact applications.

• Feedstock discipline: predominantly post-consumer PET beverage bottles (PCR), augmented by select post-industrial (PIR) streams.
• Six-stage cleaning: separation, hot wash, label/adhesive removal, advanced contaminant extraction, thermal treatment (~220°C), and vacuum degassing.
• FDA validation: lots evaluated via certified labs; non-compliant batches are rejected; Berry maintains a Letter of No Objection (LNO) for food-contact rPET.

This process narrows mechanical and optical variability, enabling consistent downstream blow molding and extrusion performance. In practice, it translates into predictable bottle strength, acceptable clarity or color profiles, and dependable barrier characteristics.

Commercial Validation: Unilever Dove’s 100% rPCR Transition

Case evidence matters. Over five years (CASE-BERRY-001), Berry Global partnered with Unilever’s Dove across 80+ markets to scale HDPE packaging from 25% rPCR to 100% rPCR.

• Phase 1 (2019–2020): 25% rPCR HDPE; 10 million bottles in North America; drop-test pass rate ~98% vs 100% virgin; consumer recognition of differences was minimal (85% could not distinguish).
• Phase 2 (2021–2022): 50–75% rPCR, solving greying via multilayer co-extrusion; exterior performance matched shelf expectations; Dove embraced slightly greyer tones as an eco signal.
• Phase 3 (2023–2024): 100% rPCR HDPE, including Ocean Bound Plastic sources (Indonesia, Philippines) cleaned via Super Clean; purity >99.5%; global rollout reached ~800 million bottles in 2024.

Impact metrics:

• 12,0000 metric tons of rPCR used cumulatively (equivalent to ~6 billion bottles diverted into circular streams).
• Estimated CO₂ reduction of ~276,000 tons vs virgin baselines.
• Quality: ~99.5% conformance, zero supply outages, and increased brand favorability (+18 pts); 58% of surveyed consumers willing to pay more for recycled packaging.

Business takeaway: 100% rPCR for personal care is technically and commercially viable at global scale when supported by stable supply, robust QA, and clear consumer communication.

Balanced Perspective: The rPCR Performance Controversy

There is a legitimate debate (CONT-BERRY-001) about rPCR variability. Low-quality mechanical recycling can yield greyer color, reduced strength, off-odors, or contamination near regulatory limits. However, performance is a function of process quality and feedstock control—not of “recycled” as a generic label.

What the Data Shows

• Berry’s high-purity rPCR (Super Clean) demonstrates performance differences generally <10% vs virgin in critical tests (burst, drop, O₂ barrier) while meeting FDA migration limits with comfortable margins.
• Batch-to-batch stability improves with stringent feedstock selection (e.g., beverage-grade PET) and standardized cleaning and degassing protocols.

Practical Guidance

• Use high-quality, FDA-approved rPCR for food and beverage primary packaging, personal care, and indirect medical contexts.
• Reserve lower-quality rPCR for non-food contact use (e.g., trash liners, agricultural films), and avoid for high-risk medical drug-contact applications.
• Promote transparency via third-party certifications (APR, FDA LNO) and provide lot-level QA documentation to customers.

Vertical Integration and Full-Portfolio Advantage

Berry Global’s differentiation is not just one material or machine—it’s an end-to-end system. The company spans rigid plastics (bottles, jars), flexible and specialty films (stretch, shrink, agricultural), nonwovens (medical PPE, hygiene substrates), and closures (caps, pumps, sprayers). This breadth, paired with in-house expertise across blow molding, injection molding, extrusion, decoration, printing, and assembly, enables precision control over material blends, process conditions, and final product quality.

• Upstream-to-downstream integration can cut total cost of ownership by ~15–20% through harmonized resin sourcing, shared QA, consolidated logistics, and synchronized production planning.
• For medical and industrial markets—the dual engine of Berry’s growth—this integrated footprint proved decisive during emergencies (see COVID PPE response) and in scaling recycled content across diverse SKUs.

Regulatory, Market, and Sustainability Context

Brand commitments and policy are accelerating rPCR adoption. EU PPWR frameworks target 25% rPET in drink bottles by 2025 and ~30% rPCR across packaging by 2030, with U.S. states (e.g., CA SB 54) setting similar trajectories. Market research (RESEARCH-BERRY-001) estimates ~$15 billion global rPCR market in 2024, growing at ~18% CAGR through 2029, with rPET as the largest segment.

Berry Global’s Impact 2025 plan aligns with this arc:

• By 2025: 100% of products designed to be reusable, recyclable, or compostable.
• By 2030: Scope 1+2 carbon neutrality and ≥30% recycled content across products.
• Progress: ~25% rPET/rPE usage achieved in 2023; expanded investments in advanced recycling (e.g., Eastman partnership) to boost supply and lower cost.

Cost realities remain: rPCR often carries a 20–50% premium vs virgin due to collection, sorting, and cleaning costs, plus demand outpacing supply. Berry’s scale (targeting ~500,000 t/year rPCR consumption) and long-term contracts help stabilize pricing. Advanced/chemical recycling will further expand feedstock and is projected to approach cost parity with virgin resins later this decade.

Environmental Impact: A Simple Carbon Math Example

Using Berry’s 50% rPET bottle scenario (per TEST-BERRY-001), a 1 billion bottle program (25 g each) shifts 12,500 t from virgin PET to rPET, cutting CO₂ from ~87,500 t (all virgin) to ~58,750 t—a ~33% reduction. Multiplied across beverage and personal care portfolios, the decarbonization potential is substantial and contributes to corporate Scope 3 reductions and compliance reporting.

Quality Assurance and Risk Management

Berry’s QA system closes the loop between feedstock variability and finished packaging performance:

• Strict incoming material qualification and rejection of non-conforming lots.
• Lot-level traceability from collection origin through pelletization, blending, and molding.
• Routine mechanical, barrier, and migration testing aligned to ASTM and FDA protocols.
• Customer reporting and shared dashboards to ensure transparency across global deployments.
