# Compostable Food Packaging Certification: The 6 Questions Every Buyer Should Ask Before Ordering

"Compostable" is a legal claim, not a marketing word. In 2026, labeling packaging as compostable without the right certifications can trigger fines, shipment rejections at customs, and greenwashing lawsuits.

These six questions cover everything you need to know to certify your molded pulp food packaging — and avoid the compliance traps that catch first-time importers.

Q1: What Certifications Make Packaging "Compostable"?

It depends on where you're selling. Compostability certifications are regional, not global.

| Region | Standard | Certification Body | Logo | |:--|:--|:--|:--| | EU | EN 13432 | TÜV Austria, DIN CERTCO | OK Compost / Seedling | | North America | ASTM D6400 | BPI | BPI Compostable | | Australia | AS 4736 / AS 5810 | ABA | ABA Seedling | | Japan | JBPA standards | JBPA | GreenPla |

Critical: Certifications are NOT cross-recognized. A BPI-certified product cannot display the OK Compost logo in the EU without separate EN 13432 testing. If you sell to both the US and EU markets, you need both certifications.

The testing criteria all standards share:

| Criterion | Requirement | |:--|:--| | Biodegradation | ≥90% conversion to CO₂ within 180 days | | Disintegration | ≥90% passes through 2mm sieve after 12 weeks composting | | Ecotoxicity | Compost supports plant growth ≥90% of control | | Heavy metals | Below thresholds (Zn<150, Cu<50, Ni<25, Cd<0.5, Pb<50, Hg<0.5, Cr<50 mg/kg) |

Molded pulp from natural plant fibers (bagasse, bamboo, wood pulp) without synthetic binders typically passes all tests without difficulty. Ecosora products carry both OK Compost INDUSTRIAL and BPI certifications.

Q2: Industrial vs Home Compostable — Which Do I Need?

| | Industrial Compostable | Home Compostable | |:--|:--|:--| | Temperature | 58°C | 20–30°C | | Biodegradation time | ≤180 days | ≤365 days | | Aeration | Forced | Natural | | Certification | OK Compost INDUSTRIAL, BPI | OK Compost HOME, AS 5810 | | Real-world scenario | Municipal composting facility | Backyard compost bin |

For foodservice packaging (restaurants, cafeterias, takeout): industrial compostable is sufficient. Commercial food waste goes to industrial composting facilities, not backyard bins. The vast majority of "compostable" packaging on the market carries industrial certification only.

For consumer retail (coffee pods, home-use plates, produce bags): home compostable matters. The end user is an individual consumer, not a commercial facility, and they need packaging that breaks down in their backyard bin.

Ecosora offers both certification levels. Specify your end-of-life scenario when ordering and we'll match the right certification.

Q3: How Long Does Certification Take and What Does It Cost?

Timeline: 7–12 months total.

| Phase | Duration | Activity | |:--|:--|:--| | Biodegradation testing | 4–8 months | 180-day test period + lab setup | | Disintegration testing | 3–4 months | 12-week composting trial | | Ecotoxicity + heavy metals | 1–2 months | Plant growth + metal analysis | | Certification review | 1–2 months | Body reviews all reports |

Cost: $10,000–$20,000 per material formulation.

| Cost Item | Range | |:--|:--| | Lab testing fees | $8,000–$15,000 | | Certification body (initial) | $2,000–$5,000 | | Annual renewal | $1,000–$3,000 |

Good news: Certification is material-specific, not product-specific. If you sell the same molded pulp formulation in 5 different shapes (trays, bowls, plates, clamshells, cups), you only need one certification. But different base materials (bagasse vs bamboo pulp) or different coatings require separate certifications.

For Ecosora customers: Our standard molded pulp formulations are pre-certified. You get the certification documents within 48 hours — no 12-month wait.

Q4: Is PFAS Testing Mandatory Now?

Yes. In 2026, PFAS-free is not optional for food packaging.

| Jurisdiction | Limit | When | |:--|:--|:--| | EU (2024/2462) | ≤50 ppm total organic fluorine | Now | | EU (phase-down) | ≤10 ppm | 2027 | | California AB 1200 | ≤100 ppm | 2023 | | 12+ US states | Various bans | Active |

Testing method: Total organic fluorine by combustion ion chromatography (EN 14582 or EPA 537.1).

For molded pulp packaging, PFAS enters through two paths: 1. Water/oil-resistant coatings that historically used PFAS-based chemistry 2. Recycled paper content that may contain PFAS from previous use

The solution: PFAS-free aqueous barrier coatings (acrylic-based, PLA-based, bio-wax-based) applied to virgin fiber pulp. These coatings deliver water and oil resistance without any fluorinated chemistry.

Ecosora molded pulp packaging is manufactured PFAS-free by design, with total organic fluorine consistently below 10 ppm — verified by SGS/Intertek independent lab testing. PFAS-free certificates ship with every order.

Q5: "Biodegradable" vs "Compostable" — What Can I Actually Say on the Label?

These are legally distinct terms. Using the wrong one is greenwashing.

| Term | Legal Status in 2026 | What It Means | |:--|:--|:--| | Biodegradable | ⚠️ Increasingly illegal unsubstantiated | Breaks down eventually (no time limit, no conditions) | | Compostable (Industrial) | ✅ Legal with certification | 90% degradation in 180 days at 58°C + ecotoxicity pass | | Home Compostable | ✅ Legal with certification | Same as above but 365 days at 20–30°C |

Regulatory pressure: EU Directive 2024/825 (Empowering Consumers for the Green Transition) bans generic "biodegradable" claims without specified timeframe and conditions. US FTC Green Guides require qualified, substantiated environmental claims.

Correct labeling for molded pulp food packaging: - ✅ "Compostable — Certified to EN 13432 by TÜV Austria" (with OK Compost logo) - ✅ "Compostable — Certified by BPI to ASTM D6400" (with BPI logo) - ❌ "Biodegradable" (alone, unqualified) - ❌ "Eco-friendly packaging" (vague, unsubstantiated)

Q6: How Do Compostability Certifications Fit with PPWR?

The EU's Packaging and Packaging Waste Regulation (PPWR) is the biggest regulatory shift in packaging in 30 years. Here's how compostability certifications interact with it:

What PPWR says about compostable packaging (Article 8): - Packaging must be recyclable at scale by 2030 - Exception: Specific applications (tea bags, coffee pods, fruit stickers, very lightweight plastic bags) may be compostable instead of recyclable - Compostable packaging must meet EN 13432 or equivalent

What this means for molded pulp food packaging: - Molded pulp is widely recyclable in paper streams — so it meets the primary PPWR requirement via recycling - EN 13432 certification provides a second compliance pathway where recycling infrastructure is unavailable - PPWR's recycled content requirements (Article 7) apply to plastic packaging only — molded pulp from virgin renewable fibers is exempt - PFAS restrictions (Article 11) align with EU 2024/2462

Documentation required beyond EN 13432 for PPWR compliance: - Conformity assessment (Module A — internal production control) - Technical documentation demonstrating compliance with essential requirements - EU Declaration of Conformity signed by manufacturer or authorized representative

Ecosora provides the complete PPWR documentation package with every EU-market order.

One More Thing: Certification Is a Selling Tool, Not Just a Requirement

When your buyer in Germany asks "Is this packaging compostable?", they're not just checking a box. They're deciding whether your product qualifies for their company's ESG procurement policy, whether it avoids the EU's single-use plastic restrictions, and whether their customers will pay a premium for it.

The right certifications — on the right documentation — turn a compliance checkbox into a competitive advantage.
