Ask which question the claim answers

“Bio-based” describes a sourcing question. “Biodegradable” describes breakdown under particular conditions. “Compostable” refers to a defined disposal context and supporting criteria. These terms should not be used as interchangeable badges on a product page or wrapper.

The European Commission’s framework makes that distinction. A procurement brief becomes clearer when it asks separately what the product contains, what the evidence demonstrates and where the customer can responsibly dispose of it.

Look at the finished item and the stated conditions

Request the exact environmental claim being proposed and the documents that support it. Check whether the evidence covers the finished straw or a different item such as a raw resin. Product identity, geometry and the scope of the test matter when assessing whether a document is relevant.

Ask which setting is covered. Home and industrial composting are not the same claim. TÜV AUSTRIA explains the distinction between its home and industrial compostability schemes. An industrial-only certificate should not be presented as proof of home compostability.

Check the certificate with the issuer and retain the current version in the product file. If a customer-facing mark is proposed, confirm the right to use it on the specific product and packaging. References to certification bodies on this website are explanatory; they are not claims that our products are certified by those bodies.

Consider the disposal route the customer actually has

Even a clearly documented product needs an appropriate collection and treatment route. Ask the buyer or local waste operator whether the intended product is accepted. A claim on the wrapper should not encourage a disposal route that the customer cannot access or that the local operator rejects.

The FTC’s guidance calls for appropriate evidence and qualification of environmental claims. In practice, the packaging team should work from the approved product file rather than adding broad green language at the end of the design process.

Use a short evidence request

  • What is the complete formulation of the selected straw?
  • Which environmental statement is being made?
  • What product, dimensions and conditions do the documents cover?
  • Who issued the evidence, and can its status be verified?
  • Which disposal route is available in the destination market?
  • Does the wrapper wording match the evidence and local requirements?

Keep these answers alongside food-contact documentation and the sample approval record. They solve different parts of the purchasing decision. Visit our Sustainability & Certifications page for the evidence framework, or include your required claim and destination in a wholesale inquiry.
