Start with the meaning, then ask for evidence
Biodegradable describes breakdown through biological activity under suitable conditions. The word alone does not tell you where that will happen or how quickly. Compostable is more specific: the claim needs evidence for the product and the stated composting conditions. Neither description means an item can be discarded into the environment.
Bio-based describes the origin of material. It does not, by itself, establish a finished product's compostability.
Distinguish commercial and home composting
Check which environment the evidence covers. BPI's directory, for example, lists commercially compostable certified items; only items marked positively in its home-compostability column also have home certification. A commercial certification therefore does not establish suitability for a home compost pile.
Match the document to the item you will buy
Ask for the exact SKU, material and any coating, then check the certificate holder, covered product and applicable conditions. A supplier logo or certificate for another item is not enough. Review lids and other components separately where they differ. Food-contact documentation answers a different question from compostability evidence.
Plan collection before making a disposal claim
Ask your waste contractor or receiving facility whether it accepts that exact item, including coatings and food residue. Certification does not establish that collection is available at your location. If acceptance is unclear, follow local waste guidance rather than promising customers that the item will become compost.
Make your GoEco enquiry specific
Send the selected product, intended use and proposed disposal arrangement. Ask for the documents applicable to that item. Use this guide to prepare questions; it does not certify GoEco's entire range or promise a breakdown time.
