TÜV OK Compost INDUSTRIAL vs HOME: When Each Certification Matters for B2B Compostable Packaging Procurement in 2026

SAYRU Team Avatar

For B2B procurement teams sourcing compostable packaging in 2026, TÜV Austria‘s OK Compost certifications are increasingly important — particularly the distinction between OK Compost INDUSTRIAL (the standard industrial compostability certification) and OK Compost HOME (the more stringent certification for home composting capability). For some applications, INDUSTRIAL certification is fully sufficient and HOME certification adds no commercial value. For others — particularly products with consumer-facing home compostability claims, products targeting markets without industrial composting infrastructure, products with sustainability messaging tied to “anyone can compost this” positioning — HOME certification is the difference between a defensible claim and an unsubstantiated marketing statement.

This guide is the working B2B procurement reference for understanding the TÜV OK Compost INDUSTRIAL vs HOME distinction. It walks through what each certification actually tests, where they overlap and where they differ, which product categories typically carry which certifications, the procurement decision framework for choosing INDUSTRIAL-only vs INDUSTRIAL+HOME, and the customer communication implications of each certification level.

For the broader certification ecosystem context, our BPI, TÜV, EN 13432 certifications guide is the foundational reference. For US-specific BPI procurement protocol, our BPI certification deep dive covers the parallel certification mechanics. This article goes specifically into the INDUSTRIAL vs HOME distinction.

TÜV Austria and the OK Compost Program

TÜV Austria operates the OK Compost certification program — one of the most internationally portable compostability certification schemes. The program includes multiple variants:

  • OK Compost INDUSTRIAL — the standard industrial compostability certification (technically based on EN 13432)
  • OK Compost HOME — certification for home composting compatibility
  • OK Compost MARINE — certification for marine biodegradability
  • OK Compost SOIL — certification for soil biodegradability
  • OK Biobased — certification of biological feedstock content

The two most relevant for foodservice B2B procurement are INDUSTRIAL and HOME. The others are important for specific applications (PHA marine-degradability claims, agricultural mulch films, etc.) but less broadly relevant.

OK Compost INDUSTRIAL: The Standard Bar

OK Compost INDUSTRIAL is the certification for compostability under industrial composting facility conditions. The test parameters:

Temperature: 58°C ± 2°C (typical industrial composting facility operating temperature)

Microbial population: Standardized industrial composting microbial communities

Moisture: Controlled moisture levels matching industrial facility conditions

Time: 90% biodegradation within 6 months under these conditions

Substrate-agnostic: Tests both bioplastic and fiber-based products against the same biodegradation requirements

Disintegration: Less than 10% of original mass retained on 2mm sieve after 12 weeks

Ecotoxicity: Resulting compost must support plant growth without toxic effects

Heavy metals and contaminants: Defined thresholds (slightly more stringent than ASTM D6400 in some specifics)

Fluorine content limits: Effectively act as a PFAS exclusion criterion (though OK Compost INDUSTRIAL doesn’t explicitly call out PFAS as ASTM/BPI does)

A product carrying OK Compost INDUSTRIAL has been independently tested and certified to meet these requirements. Industrial composting facilities accepting properly certified product can reasonably expect the product to compost within their operational windows.

OK Compost INDUSTRIAL is the European industrial compostability standard equivalent to BPI’s ASTM D6400 / D6868 certification in the US market. The full standards comparison is in our ASTM D6400 vs EN 13432 vs OK Compost standards comparison.

OK Compost HOME: The More Stringent Bar

OK Compost HOME is certification for compostability in home composting conditions. These are materially different conditions:

Temperature: 20-30°C (ambient temperature; significantly lower than industrial facility 58°C)

Microbial population: Variable; less consistent than industrial conditions

Moisture: Variable; depends on home compost pile management

Time: 90% biodegradation within 12 months under home composting conditions

Substrate sensitivity: The lower temperature and less controlled conditions of home composting are much more challenging for many materials than industrial conditions. Many products that pass INDUSTRIAL fail HOME because they don’t break down quickly enough at lower temperatures.

The disintegration, ecotoxicity, heavy metals, and contaminant requirements parallel INDUSTRIAL but applied to home compost conditions.

A product carrying OK Compost HOME has demonstrated the much harder achievement of breaking down under typical home composting conditions — meaning consumers can reasonably claim to compost the product in their backyard pile.

The Practical Test Differences That Matter

For B2B procurement, the key practical differences between INDUSTRIAL and HOME certifications:

Pass rate. The pass rate for HOME certification is meaningfully lower than INDUSTRIAL — many compostable products that pass INDUSTRIAL fail HOME because they don’t break down efficiently at home composting temperatures.

Cost. HOME certification costs 30-60% more than INDUSTRIAL certification per SKU, both in initial testing fees and in ongoing recertification.

Material limitations. Some compostable materials inherently can’t pass HOME (industrial-only PLA grades, some heavily-coated paperboard products). Some materials that meet HOME requirements (uncoated bagasse, specific PHA grades) provide a meaningful procurement advantage.

Marketing claim differential. HOME certification supports consumer-facing “compostable in your backyard” claims that INDUSTRIAL certification doesn’t.

When INDUSTRIAL-Only Is Sufficient

For most B2B foodservice procurement, INDUSTRIAL certification is the sufficient bar. Specifically:

Restaurant operations. End-of-life pathway is via the restaurant’s commercial waste disposal. The customer doesn’t compost the package at home; the restaurant or commercial composter handles end-of-life. INDUSTRIAL certification fully covers this scenario.

Catering operations. Same as restaurant operations — end-of-life is via commercial channels rather than consumer home composting.

Coffee shops, juice bars, bubble tea shops. Customer takes the package away but typically discards it in commercial waste streams (or at home in regular trash); home composting is not the typical disposal pathway. INDUSTRIAL is sufficient.

Hotels and hospitality. Commercial waste channels for end-of-life. INDUSTRIAL sufficient.

Ghost kitchens / delivery operations. Customer receives package; typical end-of-life is municipal waste or, in some markets, municipal commercial composting. INDUSTRIAL sufficient.

For these typical B2B scenarios, the higher per-unit cost of HOME-certified product doesn’t translate to meaningful commercial advantage. INDUSTRIAL is the right procurement default.

When HOME Certification Adds Real Value

Specific scenarios where HOME certification justifies the cost premium:

Scenario 1: Markets Without Industrial Composting Access

In US markets where commercial composting infrastructure doesn’t exist (most rural areas, many mid-tier cities), the only realistic compost pathway is consumer home composting. HOME certification is the difference between honest claim (“compostable in your home compost”) and overclaim (“compostable” with implicit dependency on infrastructure that doesn’t exist locally).

The full infrastructure landscape is in our industrial composting access map.

Scenario 2: Consumer-Facing Brands With Home Composting Messaging

Brands whose customer base actively composts at home (sustainability-focused consumer brands, garden/food-producer-targeted brands) benefit from HOME certification because their customer base actually uses the certification.

Scenario 3: Compostable Bag SKUs

Compostable bags are a specific category where HOME certification matters because consumers genuinely use compostable bags in home composting contexts. Compostable kitchen waste bags, compostable produce bags, and compostable lawn-and-leaf bags all benefit from HOME certification supporting consumer-facing claims.

Scenario 4: Educational and Children-Focused Brands

Educational brands using compostable packaging in classroom or child-focused contexts (school lunch programs supporting student-driven composting, summer camp foodservice with composting curricula) benefit from HOME certification because the educational use case involves children directly composting items.

Scenario 5: Specific Premium Positioning

Some premium brands position HOME certification as a differentiator — “even more compostable than the standard.” This works as marketing positioning where the brand has both the budget for the certification premium and the customer base that values the certification differentiation.

Product Categories That Typically Carry HOME Certification

Compostable product categories where HOME certification is more commonly available:

Uncoated bagasse and molded fiber products. Pure fiber (without bioplastic coatings) breaks down efficiently in home compost. Many uncoated bagasse bowls, plates, and trays carry HOME certification alongside INDUSTRIAL.

Specific PHA-based products. PHA grades suitable for home composting do exist; some PHA straws and PHA-based films carry HOME certification. The full PHA materials reference is in our PHA straws explained guide.

Compostable kitchen waste bags. A category where HOME certification is essentially expected; consumer use case is direct home composting.

Some kraft paper products. Uncoated kraft paper breaks down in home compost; coated kraft paper typically requires industrial conditions.

The materials that almost never carry HOME certification:

Standard PLA products. PLA’s slow breakdown at lower temperatures means most PLA products are INDUSTRIAL-only. The full PLA materials context is in our PLA vs PHA vs bagasse materials guide.

Heavily coated fiber products. PFAS-free coatings are still bioplastic coatings; the coating chemistry typically requires industrial composting conditions.

Paper products with PLA inner barrier. The PLA layer’s home-compostability sensitivity carries through to the finished product.

How to Verify HOME Certification

The procurement verification protocol for HOME certification:

Step 1: Request the specific TÜV certification document. OK Compost HOME certification produces a separate certificate from INDUSTRIAL. Request both if claiming both certifications.

Step 2: Verify in TÜV Austria’s certification database. TÜV maintains a public certification database; verify the specific SKU’s HOME certification number returns active status.

Step 3: Check certificate dates. HOME certification has expiration dates and recertification requirements similar to INDUSTRIAL.

Step 4: Verify certificate matches product SKU exactly. A general “product family” claim doesn’t substitute for SKU-specific HOME certification.

Step 5: Note any restrictions on the certificate. Some HOME certifications have specific use-case restrictions (e.g., “for home composting in temperate climates” — implying performance might vary in very cold or very hot climate ranges).

The general verification framework parallels the BPI verification process documented in our BPI certification deep dive — adapted for the TÜV-specific certificate format.

Customer Communication About HOME Certification

For B2B operators using HOME-certified products, customer-facing communication that lands cleanly:

For HOME-certified packaging:

“Certified compostable in your backyard compost — TÜV OK Compost HOME, in addition to industrial compostability.”

For INDUSTRIAL-only packaging:

“Industrially compostable — composts in commercial composting facilities. Where local commercial composting is available, our packaging composts there; otherwise it’s landfilled.”

The honest framing distinction is important. Don’t claim HOME compostability for INDUSTRIAL-only products even if the product technically might compost in some home conditions; the claim that survives scrutiny is exactly what’s certified.

The full sustainability communication framework that supports honest, defensible claims is documented in our how to talk sustainability without greenwashing guide.

The Procurement Decision Framework

For each compostable SKU under consideration:

Step 1: Determine if HOME certification adds commercial value for your application. If your end-of-life pathway is commercial waste / industrial composting (most B2B scenarios), HOME doesn’t add value. If your application involves consumer home composting (specific consumer brand contexts, products targeting markets without industrial composting access), HOME may justify cost premium.

Step 2: Verify available HOME-certified options in your needed product categories. Some categories (uncoated fiber, kitchen waste bags, certain PHA products) have HOME-certified options; others (most clear PLA cups, most coated paperboard) don’t.

Step 3: Calculate cost-vs-benefit. HOME certification adds 5-15% per-unit cost typically. Compare to commercial benefit (more credible marketing claim, market access in non-industrial-composting regions, premium positioning value).

Step 4: Document procurement decision rationale. For institutional and major brand procurement, the choice between INDUSTRIAL-only and INDUSTRIAL+HOME is auditable; document the reasoning.

Compliance Layer: What Each Certification Satisfies

For B2B procurement satisfying state regulatory frameworks:

California SB 54 alignment. Both INDUSTRIAL and HOME certifications satisfy SB 54’s compostability pathway. INDUSTRIAL is the practical baseline; HOME is additional. Full framework in our California SB 54 compliance guide.

State packaging EPR frameworks. Same pattern — INDUSTRIAL satisfies the compliance requirements; HOME adds optional sustainability claim differentiation.

PFAS regulatory compliance. Independent of compostability certification level. Per-SKU PFAS-free attestation required regardless of INDUSTRIAL vs HOME. Full framework in our PFAS compostable foodware guide.

What “Done” Looks Like for the INDUSTRIAL vs HOME Decision

A B2B operator with mature procurement discipline around the INDUSTRIAL vs HOME certification choice in 2026 has:

  • Clear understanding of which application contexts in the operation actually benefit from HOME certification
  • INDUSTRIAL certification verified per SKU as the standard procurement baseline
  • HOME certification verified per SKU specifically for SKUs where it adds commercial value
  • Customer-facing communication tuned to certifications actually held (no overclaim of HOME compostability for INDUSTRIAL-only product)
  • Cost-vs-benefit documented for the HOME premium where applicable
  • Quarterly compliance refresh covering both certification levels where applicable

For most B2B operations, INDUSTRIAL is sufficient across the standard SKU portfolio across compostable food containers, bowls, cups and straws, paper hot cups, and the broader compostable food containers range. HOME certification is selective addition for specific consumer-facing categories like kitchen waste bags or specific premium brand positioning.

The supply chain that supports both certification levels is mature for B2B procurement in 2026. Established compostable packaging suppliers can produce both INDUSTRIAL and HOME certifications on request for SKUs that support both. The procurement work is per-SKU verification — the same discipline that applies broadly to compostable supply chain procurement.

For custom-printed packaging specifically, the ink and substrate combinations need to be re-verified for both certification levels if HOME-compostability is claimed for the printed product. Custom-print HOME certification is more selective than standard SKU HOME certification.

The TÜV OK Compost INDUSTRIAL vs HOME distinction is one of the more nuanced procurement decisions in compostable packaging — not because the certifications themselves are confusing (they’re not; they test different conditions and are clearly differentiated) but because the commercial decision (when does HOME justify the premium) requires understanding of your specific application context and customer base.

The framework above is the path to making that decision deliberately rather than defaulting either way. Build it into procurement evaluation, document the rationale per SKU, refresh quarterly. That’s the discipline.

Background on the underlying standards: ASTM D6400 defines the U.S. industrial-compost performance bar, EN 13432 harmonises the EU equivalent, and the FTC Green Guides govern how “compostable” can be marketed on packaging in the United States.
