The OK Compost Certification addresses the growing need for reliable verification of compostable products in industrial composting facilities. It sets clear requirements ensuring materials break down safely and efficiently.
Recognized internationally, this certification supports sustainable waste management and combats greenwashing by providing scientifically backed compostability claims. Understanding OK Compost Certification helps manufacturers and consumers identify truly compostable materials aligned with global standards.
1. What Is OK Compost Certification? Definition and Core Features
The OK Compost Certification program, managed by TÜV Austria, certifies products that comply with industrial composting standards. It requires materials to biodegrade into carbon dioxide, water, and biomass without toxic residues under controlled aerobic conditions.
- Rooted in the European EN 13432 standard, it ensures products meet biodegradability, disintegration, and ecotoxicity criteria.
- This certification prevents misleading claims and guarantees that certified products support sustainable composting processes.
- Without such standards, materials labeled “compostable” may fail to degrade properly, causing environmental harm and operational issues.
2. Clarifying Common Misunderstandings
Confusion exists between terms like biodegradable, compostable, and OK Compost certified. OK Compost specifically refers to certification under strict industrial composting conditions.
For example, some biodegradable plastics degrade slowly or only in specific environments, but lack OK Compost certification to confirm industrial compostability. Third-party verification by TÜV Austria and BPI ensures credible claims and reduces greenwashing risks.
3. Industry Trends and Regulatory Recognition
Increasing regulatory focus on plastic pollution drives demand for certified compostable packaging. Authorities such as ASTM International and BPI recognize OK Compost Certification as a key compliance mark.
This certification supports circular economy goals by enabling effective organic waste diversion and material recovery. It encourages innovation in bio-based materials and aligns with global sustainability initiatives.
4. Testing and Compliance Criteria
Products seeking OK Compost Certification undergo rigorous testing for:
- Biodegradability: ≥90% conversion of organic carbon to CO₂ within specified timeframes.
- Disintegration: Complete physical breakdown in compost within 12 weeks.
- Ecotoxicity: No harmful effects on plant growth or soil organisms.
- Heavy Metal Limits: Compliant with environmental safety thresholds.
5. Comparison of Compostability Standards
| Feature | OK Compost (EU) | EN 13432 (EU) | ASTM D6400 (USA) |
|---|---|---|---|

| Environment | Industrial aerobic (58°C) | Industrial aerobic (58°C) | Industrial aerobic (58°C) |
| Degradation Period | ≤ 12 weeks (disintegration) | ≤ 12 weeks (disintegration) | ≤ 180 days (biodegradation) |
| Ecotoxicity Test | Required | Required | Required |
Practical Recommendations for Stakeholders
For Manufacturers: Pursue Certification
Design products with bio-based materials that meet OK Compost criteria. Engage accredited labs for testing and use certification labels to communicate environmental claims transparently.
For Consumers: Identify and Support
Look for the OK Compost logo as proof of industrial compostability. Dispose of certified items in industrial composting programs to ensure proper degradation.
For Policymakers: Integrate Regulations
Adopt OK Compost as an official standard for compostable packaging. Support the development of industrial composting facilities and public education programs.
Understanding the OK Compost Certification is vital for advancing sustainable packaging and waste management.
