Reading eco claims without the greenwash

Sustainability sells, so the language around disposables has become crowded with words that sound interchangeable and aren’t. For a property switching a guest-floor line, the risk isn’t only paying more for less — it’s making a public claim you can’t stand behind. Here is what the common terms actually mean.

The terms, plainly

Compostable means the item breaks down into water, CO₂ and biomass within a defined time and leaves no toxic residue — but only under specified conditions. Crucially, “compostable” almost always means industrially compostable (a commercial facility running at roughly 58°C), not something that will break down in a garden bin or in landfill.

Biodegradable only means something will eventually break down by biological action. There is no time limit and no residue standard implied, so on its own it is the weakest of the claims — a term to treat with caution unless it is qualified.

PLA and CPLA are plant-based bioplastics (typically from corn starch) used for cups, cutlery and lids. CPLA is a heat-tolerant, crystallised form for hot applications. Both are designed for industrial composting — they are not conventional plastics, and they are not home-compostable or recyclable in a normal plastics stream.

Plant-based describes what a product is made from, not how it ends its life. A plant-based item is not automatically compostable, and a compostable item is not automatically plant-based. Keep the two ideas separate.

Recyclable depends entirely on whether a local stream actually accepts and processes the material. “Recyclable” in principle is not “recycled” in practice — in a market without the collection infrastructure, the label is aspirational.

Industrial vs home composting

This is the distinction most claims blur. A cup certified for industrial composting needs a commercial facility to break down as promised; put in a general-waste bin bound for landfill, it may behave much like conventional waste. Before a compostable line genuinely closes the loop, the property needs a route for the material to reach the right facility. Worth confirming that route exists locally before the switch, not after.

Certification is the proof — the word on the pack isn’t

A claim is only as good as the standard behind it. For compostables, ask which recognised scheme the product is certified to and for the certificate itself — European standard EN 13432 and marks such as OK Compost or TÜV are the usual references for industrial compostability. A pack that says “eco” or “green” with no scheme named is making a marketing statement, not a verified one.

Questions to ask a supplier

• Is it certified compostable — and to which standard (EN 13432, OK Compost, TÜV)? Can you send the certificate?
• Industrial or home compostable? What temperature and timeframe?
• What is it made from, and does “plant-based” refer to the material or the end-of-life?
• Is there a local facility or route that actually processes it?
• For hot or oily food, is the item rated for that use (e.g. CPLA)?

How we talk about it at Emporia

Our own rule is simple: describe materials factually and name only what a product can support. Where a line is compostable or plant-based we say so plainly; where a formal certification is pending or absent we flag it rather than imply one. That is deliberately less punchy than “100% eco-friendly” — and far safer for a property that will be asked to defend the claim.
