6 Things to Avoid When Marketing Compostable Products

The compostable products category has a credibility problem, and the cause is bad marketing more than bad products. Too many brands have made vague or misleading claims that turn out to be technically false or practically unverifiable. The result is consumer skepticism that hurts the legitimate companies along with the bad ones, and a regulatory environment that has been tightening since 2012.

The FTC’s Green Guides are the binding rules in the US. The Guides have been updated multiple times (most recently in 2012, with revisions actively in development as of 2025). State-level rules — California’s SB 343 and SB 270, Washington’s HB 1799, and similar measures elsewhere — add further constraints. The European Green Claims Directive applies in the EU and increasingly serves as a de facto reference for global brands.

The penalties for violating these rules are real: FTC settlements have included $0.5M-2M+ payments, mandatory disclaimers, and bans on continued use of specific claims. State enforcement and class-action lawsuits add to the exposure. This post walks through six specific marketing patterns to avoid — what they are, why they’re problematic, and what the alternatives look like.

1. Calling something “compostable” without specifying the conditions

The single most common Green Guides violation in this category is using “compostable” as an unqualified standalone claim. The FTC’s position: an unqualified compostable claim implies the product will compost in a backyard pile within a reasonable timeframe. If your product actually requires a commercial composting facility, the unqualified claim is deceptive.

The fix: specify the conditions. Acceptable claims include:

• “Commercially compostable in industrial composting facilities”
• “Home compostable” (only if the product is actually certified for home compost — TÜV OK Compost HOME or Vincotte certification)
• “Compostable in [specific] commercial facilities” with citation to certification

Unacceptable: “compostable” alone, on packaging or marketing material, with no qualifier.

The state-level rules tighten this further. California’s SB 343 specifically prohibits the use of the word “compostable” on products that are not BPI-certified and not accepted in California’s local composting infrastructure. A nationally certified product that local California facilities don’t accept can’t be marketed as compostable in California even if it is genuinely compostable in other regions.

2. Using vague terms like “eco-friendly,” “green,” or “natural” as standalone claims

Words like “eco-friendly,” “green,” “earth-friendly,” “sustainable,” “natural,” and “responsibly made” are not regulated as strictly as “compostable” but are still subject to the FTC’s general deception rules. The standard: don’t make claims you can’t substantiate.

A product can be marketed as having “less environmental impact than [specific comparison]” if you have data to support that specific comparison. A product cannot be marketed as “eco-friendly” with no further specificity, because the term is too vague to verify.

The 2012 Green Guides specifically called out “environmental marketing claims that suggest no environmental harm” as deceptive when the product still has environmental impact (which all products do). “Made from recycled material” with the percentage is fine; “eco-friendly” alone is not.

The practical fix: replace vague words with specific facts. “Made with 80% bagasse fiber” beats “eco-friendly.” “BPI-certified compostable” beats “green.” “Does not contain PFAS” beats “non-toxic.”

3. Mismatched certification logos

The compostable certifications — BPI in North America, TÜV OK Compost (industrial and home variants) in Europe, ABA in Australia, JBPA in Japan — each have specific logo guidelines about how they can be displayed. Misusing the logos is enforced both by the certifying body and (for misleading consumers) by the FTC.

Common mistakes:

• Using the BPI logo on products that have applied for certification but not received it
• Using the BPI logo on products certified at the manufacturer level for one product but extended to other products without separate certification
• Using a “compostable” leaf-graphic logo that looks like a certification mark but isn’t tied to any actual certifying body
• Using the OK Compost HOME logo on a product certified only for industrial composting

The certifying bodies actively monitor for unauthorized use and pursue enforcement. BPI has sent cease-and-desist letters and removed certification from products that misused logos. The downstream consequences include lost certification, retailer delisting, and class-action exposure.

The fix: use logos exactly as the certifying body’s guidelines specify, only on products that are currently certified, and verify your product’s certification is current before each marketing campaign.

4. Implying products break down “in nature” or “in landfills”

A common marketing claim that the FTC has explicitly addressed: that a compostable product “breaks down in landfills” or “biodegrades naturally in the environment.” Both are deceptive in most cases.

Compostable products in landfills do not effectively break down because landfills lack the oxygen and microbial conditions that drive composting. The bagasse plate in a landfill might break down over decades or centuries, but it does not compost in the way the product’s marketing suggests. Claims that imply rapid landfill biodegradation are deceptive.

Similarly, claims that products “biodegrade naturally” if they end up in waterways or soil are problematic. Some compostable bioplastics (PLA in particular) do not effectively degrade in cold seawater, freshwater, or soil environments. They require either commercial composting or, for some PHA variants, marine environments with specific microbial conditions.

The fix: be specific about what conditions the product actually breaks down under. “Compostable in commercial composting facilities” is honest. “Biodegradable in nature” is generally not, unless you have specific test data for the specific environment.

The 2012 FTC settlement with several biodegradable plastic additive companies (including ECM BioFilms and AJM Packaging) involved exactly this kind of claim. The companies paid penalties and were required to disclaim or remove the claims.

5. Claiming “carbon neutral” without verified offsets

The compostable products category frequently sees “carbon neutral” or “net zero” marketing claims that don’t hold up to scrutiny. The Green Guides require substantiation, and the substantiation standard for net-zero or carbon-neutral claims is higher than for many other categories because the math is complex.

Acceptable substantiation includes:

• Third-party verified life-cycle assessment (LCA) showing measured emissions, reduction efforts, and high-quality offsets covering the residual
• Compliance with a recognized carbon-neutral standard (PAS 2060, or specific ISO standards)
• Disclosure of what’s covered (full lifecycle vs. operations only, what offsets cover)

Unacceptable: a “carbon neutral” claim based on unverified offsets, on partial-lifecycle calculations that exclude major emission sources, or based on internal calculations that haven’t been third-party verified.

The European Green Claims Directive has been particularly strict on carbon-neutral claims, with several proposals to ban offset-based carbon-neutral claims entirely. Brands operating internationally should expect the carbon-neutral claim category to face increasing constraints.

The fix: if you make a carbon-neutral claim, get third-party verification. If you can’t, replace the claim with specific reductions (“38% lower carbon footprint than industry-standard plastic equivalent, third-party verified”) rather than vague net-zero language.

6. Implying the product solves a problem it doesn’t actually solve

The most damaging marketing patterns in compostable products are claims that the product solves environmental problems it actually does not solve.

The most common forms:

• “Solves the plastic problem”: Compostable products reduce plastic waste in some streams, but they don’t solve marine plastic pollution, microplastic contamination, or the broader plastic crisis. A compostable cup that ends up in the ocean still doesn’t biodegrade in seawater conditions; it persists similarly to traditional plastic for unknown timeframes.
• “Fully recyclable”: Compostable bioplastics are not recyclable in the traditional plastic recycling stream. Mixing compostable bioplastics with PET or HDPE recycling actually contaminates the recycling stream. “Recyclable through composting” is the more honest framing.
• “Returns to the earth”: This implies a clean return-to-soil process that requires specific commercial composting infrastructure to actually happen. In practice, most compostable products in the US end up in landfill because of insufficient composting infrastructure. The “returns to the earth” marketing implies an outcome that doesn’t actually occur for the majority of products sold.

The fix: be honest about what the product does and doesn’t do. “Designed to compost in commercial facilities; check local availability” is honest. “Returns to the earth” is misleading without infrastructure context.

A note on the upcoming Green Guides revisions

The FTC’s Green Guides are in active revision as of 2025-2026, and the changes will likely tighten the constraints on compostable claims further. The proposals under public discussion include:

• Stricter requirements for “compostable” claims, with explicit disclosure of whether the product requires industrial vs. backyard composting
• Required disclosure of regional composting infrastructure availability for “compostable” claims
• Tighter rules on “carbon neutral” and “net zero” claims, potentially banning offset-based versions
• Specific rules on “biodegradable” claims that distinguish between regulated definitions and informal usage

Brands marketing compostable products should expect the rules to get tighter, not looser, over the 2026-2030 horizon. Marketing copy written today should anticipate these tightening rules — claims that are marginal under current rules will likely be non-compliant in 2-3 years.

A note on the EU Green Claims Directive

For brands selling internationally, the EU Green Claims Directive (in force as of 2024-2025 with phased implementation) applies parallel constraints:

• “Generic environmental claims” without substantiation are prohibited
• Substantiation requires third-party verification under recognized standards
• Sustainability labels require recognized certification
• Comparative claims require methodology disclosure

A brand that sells in both the US and the EU should default to the more restrictive standard across both markets. Trying to maintain different marketing copy for different jurisdictions is operationally difficult and creates legal exposure when copy gets reused inadvertently.

What good compostable products marketing looks like

The honest version of compostable products marketing actually performs well in the market — customers reward specificity and credibility over vague greenwashing. Examples of marketing language that meets FTC Green Guides standards and avoids the six pitfalls above:

• “BPI-certified commercially compostable. Compost in your municipal organics bin where accepted.”
• “Made from sugarcane fiber (bagasse). Carbon footprint per unit: 28% lower than equivalent paper-pulp products, verified by [third party].”
• “Home compostable, certified by TÜV OK Compost HOME. Breaks down in 6-12 months in a backyard compost pile.”
• “Replaces 1 lb of fossil-fuel plastic per case used. Made in a Wisconsin facility powered 80% by solar.”

These claims are specific, verifiable, and actionable. They tell the customer what the product is, where it can compost, and what concrete environmental benefit it provides. They don’t claim the product will save the world.

The cost of getting this wrong

The brands that have been hit by FTC enforcement, state attorney general action, or class-action lawsuits over compostable claims have generally faced cost ranges of $500K to $5M+ depending on the violation. Some have lost shelf access at major retailers. Some have lost certification entirely.

More damaging than the direct cost is the brand damage. A company caught in greenwashing carries that reputation indefinitely. The compostable products category as a whole carries some of this damage from past misleading marketing — every well-intentioned brand pays a price for the mistakes of the bad actors. Honest, specific marketing isn’t just legally safer; it rebuilds the credibility of the category that allows compostable products to actually replace plastic at scale.

For brands selecting compostable products to market, sourcing from established BPI-certified suppliers — across the tableware, utensils, and trash bag categories — gives you the certification documentation and material specs you need to make compliant claims. Skip the “eco” branding and let the product specs speak.

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.
