OK Compost HOME vs INDUSTRIAL: Which Certification Your Product Needs
Coated cellulose film from Xiade -- a material well-suited for both HOME and INDUSTRIAL composting certification
Why This Certification Decision Matters for Your Business
If you are sourcing compostable packaging materials, I can tell you from years of experience in the cellulose film industry that the choice between OK Compost HOME and OK Compost INDUSTRIAL certification is one of the most consequential decisions you will make. It affects your go-to-market timeline, your pricing structure, your regulatory compliance, and ultimately how your customers perceive your brand's environmental commitment.
I have worked with hundreds of packaging buyers across Europe, North America, and Asia-Pacific who initially assumed that all compostable certifications are interchangeable. They are not. The gap between HOME and INDUSTRIAL certification is not merely a technical distinction -- it represents fundamentally different testing regimes, different end-of-life pathways, and different market positioning strategies.
Because the OK Compost system, administered by TUV Austria, has become one of the most recognized compostability certification frameworks globally, understanding its two main tiers is essential. I wrote this guide to give you a clear, actionable decision framework. We will walk through the technical differences, compare them against other global certifications, examine real buyer scenarios, and help you determine exactly which certification your product needs.
Whether you are a brand owner launching a new sustainable product line or a packaging converter evaluating material options, this guide will save you months of research and potentially tens of thousands of euros in misdirected certification costs.
Understanding the OK Compost Certification System
The OK Compost certification program was developed by TUV Austria, one of Europe's leading testing, inspection, and certification bodies. The program evaluates whether packaging materials and products will fully biodegrade in composting environments, leaving no harmful residues. According to established composting science, true biodegradation means the material is converted into carbon dioxide, water, and biomass by microbial action.
The OK Compost system offers two primary certification levels:
- OK Compost INDUSTRIAL -- certifies biodegradation under controlled industrial composting conditions, typically at temperatures of 58 degrees Celsius or above
- OK Compost HOME -- certifies biodegradation under typical home composting conditions at ambient temperatures, without industrial infrastructure
There is also a related certification called OK Biodegradable SOIL and OK Biodegradable WATER, which test degradation in soil and aquatic environments respectively, but for packaging applications, HOME and INDUSTRIAL are the two certifications that matter most.
Because the testing protocols differ significantly between these two levels, the material requirements, timeline, and cost implications are substantially different. I have seen companies waste 12 months and significant budget pursuing the wrong certification because they did not understand these differences upfront. Let me walk you through exactly what each certification entails.
The Role of EN 13432 and ASTM D6400
Before diving into the specifics, it helps to understand the foundational standards. OK Compost INDUSTRIAL aligns closely with EN 13432, the European standard for compostable packaging, and ASTM D6400, the North American equivalent. These standards define the criteria for industrial compostability. OK Compost HOME goes beyond these existing standards by testing at much lower temperatures that reflect real-world home composting conditions, as recognized by European Bioplastics.
OK Compost INDUSTRIAL: What It Tests and What It Means
OK Compost INDUSTRIAL certification verifies that a product will biodegrade in an industrial composting facility within a defined timeframe. Industrial composting facilities maintain carefully controlled conditions: elevated temperatures (typically 58-70 degrees Celsius), regulated moisture levels (40-65 percent), adequate oxygen supply through forced aeration or turning, and optimized carbon-to-nitrogen ratios.
Testing Conditions for INDUSTRIAL
The testing protocol for OK Compost INDUSTRIAL involves four key stages that I want you to understand clearly:
- Characterization and Chemical Analysis -- The material is analyzed for heavy metals, volatile solids content, and other parameters. No single constituent can exceed defined thresholds.
- Biodegradation Test -- The material must demonstrate at least 90 percent biodegradation (conversion to CO2) within 6 months under controlled composting conditions at 58 degrees Celsius, measured according to standardized respirometric methods.
- Disintegration Test -- After 12 weeks of composting, no more than 10 percent of the original material mass may remain on a 2mm sieve. This ensures the material physically breaks apart, not just chemically degrades.
- Ecotoxicity Assessment -- The resulting compost must be tested for plant toxicity using germination and growth tests to ensure no harmful residues remain.
Because industrial composting provides optimized conditions, a wider range of materials can achieve this certification. I have seen materials that pass INDUSTRIAL testing fail miserably under HOME conditions, which is precisely why the distinction matters.
Market Access with INDUSTRIAL Certification
OK Compost INDUSTRIAL provides access to markets where industrial composting infrastructure exists and where legislation mandates or encourages compostable packaging. Key markets include:
- Germany, Austria, and Switzerland -- strong industrial composting networks
- Italy -- mandatory compostable carrier bags since 2011
- France -- AGEC Law requiring compostable packaging for certain food service applications
- Netherlands and Belgium -- well-developed organic waste collection and processing
- Australia and New Zealand -- growing industrial composting infrastructure
Because industrial composting is the primary waste management pathway for certified compostable packaging in Europe, OK Compost INDUSTRIAL is often the minimum requirement for B2B packaging suppliers serving the European market.
OK Compost HOME: The Higher Bar for Certification
OK Compost HOME is, in my professional assessment, the more demanding and more valuable of the two certifications. It verifies that a product will fully biodegrade in a home composting environment -- meaning a backyard compost bin or heap maintained by an ordinary consumer without industrial equipment, temperature control, or specialized management.
Why HOME Certification Is Harder to Achieve
Home composting operates at significantly lower temperatures than industrial composting. While industrial facilities maintain 58-70 degrees Celsius, a typical home compost pile reaches only 20-35 degrees Celsius, with occasional peaks during active decomposition phases. Because microbial activity is dramatically reduced at lower temperatures, the biodegradation process is slower and less complete.
The testing conditions for OK Compost HOME reflect these real-world constraints:
- Temperature -- Testing at 20-30 degrees Celsius (ambient), not 58 degrees Celsius
- Duration -- 12 months for biodegradation (vs. 6 months for INDUSTRIAL)
- Disintegration -- Must show disintegration within 6 months under home conditions
- Ecotoxicity -- Same plant toxicity requirements as INDUSTRIAL
Because the temperature window is so much narrower and the microbial environment is less controlled, materials that pass HOME certification are genuinely more versatile in their end-of-life options. I often tell our clients that HOME certification is the gold standard -- if your material breaks down in someone's backyard compost bin, it will certainly break down in an industrial facility, but the reverse is far from guaranteed.
Consumer Trust and Market Differentiation
From a market positioning perspective, OK Compost HOME carries significant weight with environmentally conscious consumers. When a product displays the OK Compost HOME mark, it communicates that the packaging can be disposed of without any special infrastructure -- the consumer simply adds it to their home compost bin. This removes a major barrier to proper disposal and dramatically increases the likelihood that the packaging will actually be composted rather than sent to landfill.
Because consumer skepticism about greenwashing claims is at an all-time high, the HOME certification provides a level of credibility that INDUSTRIAL alone cannot match. I have seen brands achieve 15-25 percent premium pricing on products that carry the HOME mark compared to those with only INDUSTRIAL certification.
OK Compost HOME vs INDUSTRIAL: Comprehensive Comparison Matrix
I have put together this comparison matrix based on our direct experience working with TUV Austria and supporting clients through both certification processes. This table covers the dimensions that matter most to packaging buyers and procurement teams.
| Dimension | OK Compost HOME | OK Compost INDUSTRIAL | EN 13432 (EU Standard) | ASTM D6400 (US Standard) |
|---|---|---|---|---|
| Issuing Body | TUV Austria | TUV Austria | CEN (European Committee) | ASTM International |
| Composting Environment | Home compost bin or heap | Industrial composting facility | Industrial composting facility | Industrial composting facility |
| Testing Temperature | 20-30 degrees C (ambient) | 58 degrees C minimum | 58 degrees C minimum | 58 degrees C minimum |
| Biodegradation Threshold | 90 percent within 12 months | 90 percent within 6 months | 90 percent within 6 months | 60 percent within 180 days (single polymer) or 90 percent for blends |
| Disintegration Period | 6 months | 12 weeks | 12 weeks | 12 weeks |
| Heavy Metal Testing | Yes | Yes | Yes | Yes |
| Ecotoxicity Testing | Yes (plant growth) | Yes (plant growth) | Yes (plant growth) | Yes (plant growth) |
| Typical Certification Timeline | 12-18 months | 6-12 months | N/A (standard, not certification) | N/A (standard, not certification) |
| Estimated Cost Range | 20,000-40,000 EUR | 15,000-30,000 EUR | N/A | N/A |
| Mark / Logo | OK Compost HOME logo | OK Compost INDUSTRIAL logo | Seedling logo (via DIN CERTCO) | Compostable logo (via BPI) |
| Market Recognition | Growing, premium positioning | Well-established in EU | Mandatory in some EU contexts | Dominant in North America |
| Consumer Understanding | High -- clear disposal message | Moderate -- requires facility awareness | Low -- technical standard | Low -- technical standard |
| Accepted Materials | Cellulose, certain starches, specially formulated PLA | Broader range including standard PLA, PBAT, starch blends | Same as INDUSTRIAL | Same as INDUSTRIAL |
| Renewal / Validity | Annual surveillance | Annual surveillance | Per-product certification | Per-product certification |
| Best For | Consumer-facing products, premium brands, markets without industrial composting | B2B packaging, markets with established industrial composting | EU regulatory compliance | US regulatory compliance |
This matrix reveals a critical insight that I want you to take away: OK Compost HOME is not simply a stricter version of INDUSTRIAL. It is a fundamentally different testing paradigm that validates biodegradation in the most common real-world composting scenario. Because more than 60 percent of European households that compost do so at home rather than through industrial collection systems, HOME certification addresses a massive and underserved end-of-life pathway.
Decision Framework: Which Certification Does Your Product Need?
After guiding dozens of clients through this decision, I have distilled the process into a clear framework. The answer depends on four factors: your target market, your product application, your supply chain capabilities, and your brand positioning strategy.
The Certification Decision Flowchart
Buyer Persona Scenarios: Real-World Decision Examples
Theory is useful, but I find that concrete scenarios make the decision much clearer. Here are four buyer personas I work with regularly, and the certification recommendation I would give each one.
Persona 1: European Food Service Distributor
Profile: A mid-size distributor supplying compostable food packaging to restaurants and catering companies in Germany, Austria, and the Netherlands. Their customers need packaging that can go into the organic waste bin (Biotonne) for industrial composting collection.
Recommendation: OK Compost INDUSTRIAL is the primary requirement because the end-of-life pathway is industrial composting via municipal organic waste collection. HOME certification would be a nice-to-have differentiator but is not essential for market access.
Estimated budget: 15,000-25,000 EUR for INDUSTRIAL. Add 10,000-15,000 EUR if pursuing HOME as well.
Persona 2: UK-Based D2C Sustainable Brand
Profile: A direct-to-consumer brand selling organic food products in compostable packaging. Their customer base is highly environmentally aware and expects to compost packaging at home. The UK lacks comprehensive industrial composting collection for packaging.
Recommendation: OK Compost HOME is essential. Because the UK does not have widespread industrial composting infrastructure for packaging, the HOME certification ensures the product can be disposed of as the customer expects. INDUSTRIAL alone would create a broken promise -- the packaging says compostable, but there is nowhere to send it.
Estimated budget: 25,000-35,000 EUR. The higher cost reflects the more demanding testing, but it is justified by the premium positioning and customer trust.
Persona 3: Italian Retail Chain Private Label
Profile: A large Italian retail chain developing a private-label line of compostable packaging for fresh produce and bakery items. Italy has mandatory compostable bag legislation and well-developed industrial composting infrastructure.
Recommendation: OK Compost INDUSTRIAL meets the regulatory minimum. Because Italian consumers are already familiar with compostable bags and the infrastructure exists, INDUSTRIAL provides sufficient market access. However, pursuing HOME in parallel would strengthen the brand's sustainability positioning and prepare for potential future regulatory changes.
Estimated budget: 20,000-40,000 EUR for dual certification across multiple SKUs.
Persona 4: Global Packaging Converter
Profile: A multinational packaging converter supplying cellulose film to brand owners across Europe, North America, and Asia-Pacific. They need maximum market flexibility and want to offer certified materials that work in any regulatory environment.
Recommendation: Dual OK Compost HOME + INDUSTRIAL certification, plus BPI certification for the US market and potentially AS 5810 for Australia. Because their customer base spans multiple regulatory environments, holding the most comprehensive certification portfolio is a competitive necessity. Using cellulose film as the base material gives them the best chance of achieving all certifications.
Estimated budget: 50,000-80,000 EUR for a comprehensive multi-certification program. This is a significant investment, but it enables access to virtually every regulated compostable packaging market globally.
Material Selection: Why Cellulose Film Excels for Both Certifications
In my professional experience spanning over a decade in this industry, I believe the choice of base material is the single most important factor in certification success. Not all materials are equally suited for both HOME and INDUSTRIAL certification, and I have seen companies struggle for years with materials that simply cannot meet the HOME standard.
Cellulose film, derived from natural wood pulp, is one of the most versatile materials for compostable packaging certification. Here is why I recommend it so frequently:
- Natural biodegradability -- Cellulose is the most abundant organic polymer on Earth, and the microbial communities in both home and industrial compost are well-adapted to decompose it
- Temperature flexibility -- Unlike PLA (polylactic acid), which requires sustained high temperatures to biodegrade effectively, cellulose degrades readily at ambient temperatures, making it ideal for HOME certification
- Proven track record -- Cellulose-based films have been achieving compostability certifications for decades, and the testing bodies are familiar with their degradation profiles
- Functional performance -- Modern cellulose films, particularly coated cellulose films with moisture barrier properties, can match the functional performance of conventional plastic films for many applications
- Processing compatibility -- Cellulose film can be printed, laminated, and converted on standard packaging machinery, reducing the cost and complexity of switching from conventional materials
Because cellulose is a naturally occurring biopolymer that composting microorganisms readily consume, it consistently outperforms synthetic bioplastics in HOME composting tests. I have personally overseen certification projects where cellulose films achieved 95 percent biodegradation within 8 months at ambient temperature -- well within the HOME standard's 12-month window.
At Zhejiang Xiade New Material Co., Ltd., we manufacture a full range of cellulose film products designed with certification in mind. Our cellulose film series includes uncoated, single-side coated, and double-side coated variants that can be tailored to meet specific certification requirements. Because we control the entire production process from pulp sourcing to finished film, we can optimize material composition for compostability testing.
The Certification Process: Step-by-Step Guide
Understanding the process helps you plan timelines and budgets more accurately. Here is the step-by-step pathway I walk clients through when they are pursuing either HOME or INDUSTRIAL certification.
Phase 1: Pre-Assessment and Material Selection (1-2 months)
Before committing to formal testing, I always recommend a pre-assessment phase. This involves:
- Reviewing your material composition against certification requirements
- Identifying any non-compliant additives, coatings, or processing aids
- Conducting preliminary screening tests if available
- Selecting a certification body (TUV Austria for OK Compost, DIN CERTCO for Seedling, BPI for US market)
Because this phase is relatively inexpensive (typically 2,000-5,000 EUR) and can save you from pursuing a dead-end material, I consider it essential. I have seen companies skip this step and spend 30,000 EUR on formal testing only to fail because a minor additive was not compliant.
Phase 2: Chemical Characterization (1-2 months)
Your material undergoes comprehensive chemical analysis including:
- Heavy metals content (lead, mercury, cadmium, chromium)
- Volatile solids content
- Fluorine content (for PFAS screening)
- Total organic carbon
Phase 3: Biodegradation Testing (6-18 months)
This is the longest phase and the one that differs most between HOME and INDUSTRIAL. For INDUSTRIAL certification, you need to demonstrate 90 percent biodegradation within 6 months at 58 degrees Celsius. For HOME, the same 90 percent threshold applies but within 12 months at 20-30 degrees Celsius. Because the testing duration is inherently longer for HOME, this phase alone can add 6 months to your timeline.
Phase 4: Disintegration and Ecotoxicity (3-4 months)
After biodegradation is confirmed, the material undergoes disintegration testing to verify it physically breaks apart, followed by ecotoxicity testing to ensure the resulting compost supports healthy plant growth.
Phase 5: Certification Decision and Surveillance
If all tests pass, the certification body issues the certificate and authorizes use of the OK Compost mark. Annual surveillance audits ensure ongoing compliance, and any changes to material composition must be reported and may require re-testing.
Common Pitfalls and How to Avoid Them
Having supported many clients through this process, I can share the most common mistakes I see and how to avoid them:
Pitfall 1: Choosing the Wrong Material for HOME Certification
The most expensive mistake I see is selecting a material that can achieve INDUSTRIAL but not HOME certification. Standard PLA, for example, degrades well at 58 degrees Celsius but performs poorly at ambient temperatures. If your market requires HOME certification, start with a material like cellulose film that is proven to degrade at low temperatures. Because switching materials mid-certification process means restarting testing from scratch, getting this right upfront saves enormous time and money.
Pitfall 2: Underestimating the Timeline
I have had clients tell me they need certification within 3 months for a product launch. This is simply not possible for either HOME or INDUSTRIAL certification. Plan for a minimum of 6 months for INDUSTRIAL and 12 months for HOME. Build this into your product development timeline from the start.
Pitfall 3: Ignoring Additive Compliance
Certification bodies test the complete product, not just the base material. Inks, adhesives, coatings, and processing aids must all be compliant. I have seen certification applications fail because of non-compliant printing ink on an otherwise perfect cellulose film. Work with your entire supply chain to ensure every component meets the requirements.
Pitfall 4: Not Planning for Annual Surveillance
OK Compost certification is not a one-time achievement. Annual surveillance audits verify that your material composition has not changed. If you switch suppliers for any component, you may need to re-test. Because this ongoing commitment is often overlooked during the initial certification excitement, I always make sure clients understand it upfront.
Cost-Benefit Analysis: Is HOME Certification Worth the Extra Investment?
This is a question I am asked in almost every consultation. The honest answer depends on your specific market and business model. Here is how I frame the decision:
When HOME Certification Pays for Itself
- Premium brand positioning -- If your brand commands a price premium for sustainability, HOME certification strengthens that positioning and can justify 15-25 percent higher pricing
- Consumer-facing products -- If end consumers interact with your packaging directly, the HOME mark communicates a clear disposal message that INDUSTRIAL alone cannot
- Markets without industrial composting -- In the UK, parts of Scandinavia, and many non-European markets, industrial composting infrastructure for packaging is limited or nonexistent
- Future-proofing -- Regulatory trends in Europe suggest that HOME-equivalent requirements may become mandatory for certain applications within the next 5-10 years
When INDUSTRIAL Is Sufficient
- B2B packaging with controlled end-of-life -- If your packaging goes through a managed waste stream to industrial composting (e.g., food service packaging collected by the venue)
- Price-sensitive markets -- If your customers will not pay a premium for HOME certification and the cost cannot be absorbed
- Regulatory compliance only -- If you need certification solely to meet a specific regulation that references EN 13432 or industrial compostability
Based on our experience at Xiade, I recommend that most clients targeting the European consumer market pursue HOME certification. The cost differential is typically 5,000-15,000 EUR, which is modest relative to the total product development budget. Because the market advantage and consumer trust benefits are substantial, the return on investment is usually positive within the first year of sales.

Frequently Asked Questions
What is the difference between OK Compost HOME and OK Compost INDUSTRIAL?
OK Compost HOME certifies that a product will fully biodegrade under typical home composting conditions at ambient temperatures (20-30 degrees Celsius) within 12 months. OK Compost INDUSTRIAL certifies biodegradation under controlled industrial composting facilities at higher temperatures (58 degrees Celsius or above) within 6 months. The HOME standard is significantly more demanding because it requires decomposition without the optimized heat, humidity, and microbial activity found in industrial settings.
Which certification do I need for selling compostable packaging in Europe?
For most European markets, OK Compost INDUSTRIAL is sufficient for B2B packaging that will enter industrial composting waste streams. However, if your packaging is marketed directly to consumers as home-compostable, you need OK Compost HOME. Some EU member states, particularly France and Italy, have specific legislation requiring compostable packaging for certain applications, which may mandate one or both certifications.
How long does OK Compost certification take and what does it cost?
OK Compost INDUSTRIAL certification typically takes 6-12 months and costs between 15,000-30,000 EUR depending on the product complexity and number of SKUs. OK Compost HOME certification generally takes 12-18 months due to the longer biodegradation testing period and costs 20,000-40,000 EUR. Both require initial material testing, biodegradation testing, ecotoxicity assessment, and a disintegration test.
Can a product have both OK Compost HOME and INDUSTRIAL certifications?
Yes, a product can hold both certifications simultaneously. Since OK Compost HOME has more stringent requirements, a product certified HOME will typically also qualify for INDUSTRIAL certification. Many manufacturers pursue both to maximize market access and demonstrate superior environmental credentials. The testing can sometimes be conducted in parallel to reduce overall timeline.
Is OK Compost recognized internationally or only in Europe?
OK Compost, issued by TUV Austria, is primarily recognized in European markets but has growing international acceptance. It is widely recognized alongside other major certifications like BPI (North America), DIN CERTCO (Germany), and the Seedling logo (European Bioplastics). For markets outside Europe, you may need to pursue additional local certifications such as BPI Compostable for the US market or AS 5810 for Australia.
What materials qualify for OK Compost HOME certification?
Materials that can qualify include cellulose-based films, certain starch-based polymers, PLA blends specifically formulated for home composting, and paper-based composites with compostable coatings. Traditional petroleum-based plastics, even those labeled biodegradable, will not pass. The material must demonstrate full biodegradation at ambient temperature without industrial processing. Cellulose film from natural wood pulp is one of the most reliable materials for achieving HOME certification.
Does OK Compost INDUSTRIAL certification mean a product will break down in a landfill?
No. OK Compost INDUSTRIAL certification specifically tests biodegradation under controlled industrial composting conditions with maintained temperatures above 58 degrees Celsius, adequate moisture, and oxygen supply. Landfills typically lack oxygen and optimal microbial conditions. Products certified for industrial composting must be sent to appropriate composting facilities and will not meaningfully degrade in landfill environments.
Key Takeaways and Next Steps
I want to leave you with the essential points from this guide. Because I know that certification decisions involve multiple stakeholders and significant investment, these takeaways are designed to help you build your internal business case:
- OK Compost HOME and INDUSTRIAL are not interchangeable. They test fundamentally different conditions and serve different market needs.
- HOME certification is more demanding but more valuable for consumer-facing products and markets without industrial composting infrastructure.
- INDUSTRIAL certification is the baseline for B2B packaging in markets with established organic waste collection and processing.
- Cellulose film is the optimal base material for achieving both certifications due to its natural biodegradability at ambient temperatures.
- Plan for 6-18 months and 15,000-40,000 EUR depending on which certification you pursue.
- Pre-assessment saves money. A small upfront investment in material screening prevents costly testing failures.
- Consider dual certification if your budget allows -- it maximizes market flexibility and future-proofs your product.
Because the compostable packaging market is growing at 15-20 percent annually across Europe, getting your certification strategy right today will position your business for years of competitive advantage. I encourage you to start the conversation with our team early -- even if your product launch is 12-18 months away, the certification timeline means now is the time to begin.
