Introduction to Sustainability: Bio-based, Biodegradable and Compostable Materials

Major Global Certification Standards

Here’s a closer look at the key global certification standards, including their testing criteria, timelines, and regional applications. Each standard plays a critical role in determining market access and ensuring regulatory compliance.

ASTM D6400/D6868 (USA)

In the United States, ASTM D6400 is the go-to standard for compostable plastics, while ASTM D6868 applies specifically to plastic films and coatings used on compostable products. Both require that materials achieve 90% biodegradation within 180 days under controlled industrial composting conditions. This involves managing factors like temperature, moisture, and oxygen levels to ensure proper breakdown. Additionally, products must physically disintegrate completely during the composting process without releasing harmful substances that could impact soil quality or plant growth.

Certification for these standards is managed by the Biodegradable Products Institute (BPI) in North America. BPI certification involves thorough third-party testing and ongoing quality checks. However, the certification comes with certain limitations – products with adhesive seals are not eligible, as adhesives can disrupt composting.

Adhering to these standards is especially important given the FTC Green Guides, which govern environmental marketing claims in the U.S. Companies making unverified biodegradable claims risk legal challenges and penalties for greenwashing.

EN 13432 (EU)

The European Union’s EN 13432 standard sets strict requirements for industrial compostability. It involves a two-step process: materials must undergo physical disintegration within 12 weeks, leaving no more than 10% of the original material, and achieve 90% biodegradation within six months under industrial composting conditions.

Recognized by the European Commission, EN 13432 is the official standard for industrial compostability across EU member states, the UK, and parts of Asia. Certification bodies like TÜV Austria and DIN CERTCO handle compliance for this standard. TÜV Austria also offers separate certifications for home compostability, such as the OK compost INDUSTRIAL and OK compost HOME labels, helping consumers easily identify suitable products. For home compostable products, the standard requires complete decomposition within 180 days in home composting environments.

This standard doesn’t just focus on biodegradation – it also includes safety testing to ensure the resulting compost is free from harmful residues, protecting both soil health and plant growth.

ISO 17088/18606 (International)

On a global scale, ISO 17088 sets requirements for the compostability of plastics, covering biodegradation, disintegration, and environmental safety. ISO 18606, on the other hand, focuses on packaging materials designed for organic recycling, addressing challenges specific to packaging. Together, these standards provide a comprehensive framework for both industrial and home composting applications.

ISO certifications are especially valuable for companies operating in multiple markets. For example, manufacturers like JUNYUAN BAGS can use ISO compliance to showcase their commitment to environmental responsibility while meeting the varying requirements of different regions.

These standards provide clear guidelines for manufacturers aiming to meet stringent compliance requirements and build trust in environmentally conscious markets. Companies often pursue multiple certifications to ensure their products align with diverse regional regulations and gain broader market access.

Testing and Compliance Requirements

Certification involves rigorous lab testing and detailed documentation. Manufacturers must demonstrate that their products meet strict scientific criteria for biodegradability, disintegration, and safety for the environment.

Biodegradability Testing Methods

Testing methods are based on well-established standards to ensure materials perform as required. These methods focus on three main areas: biodegradation rate, physical disintegration, and ecotoxicity. Each test is designed to replicate composting conditions, ensuring the material breaks down completely and safely.

• Biodegradation Rate Testing: This test measures how quickly organic carbon in the material is converted into carbon dioxide (CO₂) under controlled composting conditions. The temperature is maintained at 136°F (58°C) with specific moisture and oxygen levels. To pass, 90% of the material must convert to CO₂ within the designated timeframe.
• Physical Disintegration Testing: This test evaluates whether the material breaks apart during composting. After 12 weeks, the compost is screened through a 2mm sieve. For EN 13432 compliance, less than 10% of the material can remain as fragments larger than 2mm.
• Ecotoxicity Testing: This ensures that the resulting compost is safe for agricultural use. Plant growth tests are performed to confirm that the compost is non-toxic and suitable for enriching soil in gardens and farms.

Industrial composting tests are conducted at 136°F (58°C), while home composting tests are performed at lower temperatures, ranging from 68–86°F (20–30°C), over extended periods.

Required Documentation for Compliance

Once testing is complete, manufacturers must provide comprehensive documentation to secure certification. This documentation is critical and must be regularly updated to maintain compliance.

• Laboratory Reports: Accredited labs must provide detailed reports on biodegradation, disintegration, and ecotoxicity tests. These reports include raw data, testing methods, environmental conditions, and statistical analyses.
• Technical and Safety Data Sheets: These sheets outline the materials used, manufacturing processes, and chemical composition. Certification bodies use this information to verify that the materials align with test results and do not include prohibited substances.
• Declarations of Conformity: These formal statements confirm that the products meet specific certification standards. They must be signed by an authorized representative and include references to relevant standards, testing dates, and certification approvals.
• Quality Control Records: These records demonstrate ongoing compliance through regular testing and monitoring. Certification bodies often require periodic retesting, batch testing records, and documentation of manufacturing processes to uphold certification status.

For example, companies like JUNYUAN BAGS must meet these documentation standards to access global markets. In the U.S., they need BPI certification under ASTM D6400, while in the EU, EN 13432 compliance is required through TÜV Austria or DIN CERTCO certification.

Failing to provide proper documentation has serious consequences. Under the Federal Trade Commission (FTC) Green Guides, uncertified products may be labeled as deceptive or accused of "greenwashing", potentially leading to fines, penalties, and product recalls. However, many manufacturers successfully navigate the process by maintaining thorough records, earning certification marks, and marketing their products as compostable in both U.S. and EU markets.

Certification organizations like the Biodegradable Products Institute (BPI) in the U.S., TÜV Austria, and DIN CERTCO in the EU ensure compliance by following standardized protocols. They issue official certificates once all testing and documentation requirements are met. This certification not only facilitates market access but also underscores a manufacturer’s commitment to environmentally responsible practices.

Certification Labels and Requirements

Certification labels serve as a visual confirmation that a product has undergone rigorous testing and meets established environmental standards. These labels not only help products gain market acceptance but also shield companies from legal trouble. On the flip side, mislabeling can lead to hefty fines and other legal consequences.

Certification Logos and Marks

Certification logos play a crucial role in verifying a product’s compostability. For instance, the U.S. BPI mark is widely recognized as the benchmark for compostable products. This logo is reserved for items that have passed independent lab tests and are certified to break down in commercial composting facilities without leaving harmful residues. As of 2024, over 10,000 products in North America have earned this certification.

In Europe, the Seedling logo signifies compliance with EN 13432 standards, ensuring that certified products disintegrate within 12 weeks and fully biodegrade within six months.

TÜV Austria offers two separate logos to clarify composting requirements. The OK compost INDUSTRIAL mark indicates that the product is designed for commercial composting facilities, while the OK compost HOME mark confirms suitability for backyard composting systems. This distinction is critical, as many consumers mistakenly assume all compostable products can be composted at home.

In the U.S., proper labeling goes beyond just displaying a certification logo. Labels should clearly identify the certifying body (e.g., BPI), the standard met (such as ASTM D6400), and often include a certification number or reference. Starting in July 2024, compostable film bags must also be tinted green, beige, or brown and display a certification logo or clear labeling to minimize confusion.

For manufacturers like JUNYUAN BAGS, securing the appropriate certification marks is essential for entering global markets. Products sold in the U.S. require BPI certification under ASTM D6400, while those destined for the EU must comply with EN 13432 and display either the Seedling logo or TÜV Austria certification marks.

Enforcement and Penalties

Strict enforcement ensures that certification marks are used correctly, and violations carry serious consequences. The Federal Trade Commission (FTC) Green Guides mandate that claims like "compostable" or "biodegradable" must be backed by evidence and must not mislead consumers. Products must also specify the appropriate composting environment.

False or misleading labels can lead to regulatory action, including fines, product recalls, and penalties under the FTC Act for deceptive marketing practices. States like California and New York have even stricter rules, banning the use of terms like "biodegradable" on plastic products unless they meet ASTM D6400 standards.

Non-compliant products may face bans or be required to undergo relabeling. Repeated violations can tarnish a company’s reputation and erode consumer trust, making it difficult to regain market standing even after achieving proper certification.

Enforcement measures include market surveillance, random inspections, and investigations into consumer complaints by agencies like the FTC and state attorneys general. Certifying bodies may also conduct audits or require periodic recertification to ensure continued compliance. Penalties for non-compliance can range from fines to public disclosure of violations, and products may even be pulled from store shelves.

The enforcement approach varies by region. In the U.S., the emphasis is on accurate labeling and substantiated claims under FTC oversight. Meanwhile, the EU enforces more harmonized standards, such as mandatory use of the Seedling logo and frequent market inspections. To avoid penalties, companies should stay updated on regulations, train staff on compliance, and conduct internal audits with trusted certifiers. For businesses operating across multiple markets, understanding these regional differences is key to maintaining compliance and avoiding setbacks.
