Making Honest Eco Claims: A Guide for UK Hospitality
Words like "eco‑friendly", "biodegradable" and "green" are everywhere on menus, signage and takeaway packaging.
In the UK, though, those words are now under real scrutiny from regulators, especially in food and drink. Most operators are not trying to mislead anyone - but repeating vague or over‑optimistic claims from supplier catalogues on your menus, website or social media can still count as greenwashing, damage customer trust and create regulatory risk for your business.
The UK green claims basics
In the UK, the Competition and Markets Authority's Green Claims Code sets the tone for what regulators see as misleading environmental claims. It says that every green claim must be:
- truthful and accurate
- clear and unambiguous
- not hide or omit important information
- consider the full life cycle of the product where relevant
- specific about what part of the product or packaging it refers to
- backed up with robust, accessible evidence
The Advertising Standards Authority applies the same thinking to ads, menus, websites and social media. Absolute phrases like "fully biodegradable", "zero‑waste" or "climate neutral" need strong, documented evidence and clear explanations of conditions (for example, in an industrial composting facility) to avoid misleading people.
Common greenwash pitfalls in food and drink
"Biodegradable" with no context
Many "biodegradable" or compostable plastics still end up in general waste or incineration in the UK, where they do not break down as promised. Without clear conditions (for example, specific temperatures or industrial composting), simply writing "biodegradable" on your menu, signage or website can be considered misleading.
Instead, say: "Made from compostable bioplastic for industrial facilities - not accepted in standard recycling or general‑waste bins" if that reflects the real disposal route.
"Compostable" with no explanation of how or where
Regulators expect you to explain where and how something composts, especially if it needs an industrial facility rather than a home compost heap. Saying "compostable" on its own can wrongly suggest it will break down in any bin, street litter or garden compost.
Vague claims like "eco‑friendly", "green" or "planet‑safe"
Terms like "eco‑friendly", "green" and "planet‑safe" are so broad that they often don't tell customers what is actually better and can exaggerate the benefits. Without context (less plastic, more recycled content, reusable instead of single‑use), they may be seen as unsubstantiated.
"Zero‑waste", "climate neutral" and other absolutes
Claims such as "zero‑waste", "climate neutral", "carbon neutral" or "net zero packaging" are high‑risk without robust life‑cycle assessments and verified offsets. In most hospitality settings, it's very hard to prove that no waste is created or that total climate impact is neutral across the full life cycle.
Implying easy recycling that doesn't exist locally
Stating or implying that your packaging is "widely recycled" or "fully recyclable" can mislead if local collections don't actually accept that material, or if food contamination means it often gets rejected by recyclers. Icons that look like recycling symbols can also be problematic if they suggest more than the infrastructure delivers.
rPET and recycled content
rPET cups and containers can be a strong step forward, but the way you communicate them to your customers matters.
What you can confidently tell your customers (if you have evidence):
- "Our cups contain at least X% recycled plastic" (for example, 30%) where that figure is backed by supplier documentation.
- "Our clear PET cups are designed to be recycled in PET streams where local collection and sorting infrastructure exists."
What to avoid on your menus and signage:
- "100% eco‑friendly" or "recycled everywhere in the UK" - not all councils collect every PET format, and event settings often rely on bespoke systems rather than kerbside.

Paper and bagasse
Paper and bagasse packaging can meaningfully reduce dependence on fossil‑based plastics, but that doesn't mean they automatically compost or recycle perfectly everywhere.
What you can tell your customers:
- "Made from plant‑based fibres (bagasse/sugarcane/paper) to reduce reliance on fossil‑based plastics."
- "Helps cut plastic use in our packaging by replacing plastic trays or clamshells with fibre‑based options."
Caveats to keep in mind:
- In many UK areas, food‑soiled paper and bagasse still go into general waste if there is no separate food‑waste or composting service.
- Calling all fibre packaging "compostable" is risky unless you have a verified industrial composting route and can explain that to customers.
Compostable lines
Compostable products can be part of a credible sustainability approach, but only where the collection and treatment pathway is clear.
Safe territory:
- You know exactly how they will be collected (for example, a dedicated food‑waste bin on site) and which contractor handles them.
- You can provide clear disposal instructions for customers, like "Use the food‑waste bin on site; do not put in mixed recycling or general‑waste bins."
Higher‑risk territory:
- Compostable lines used in settings where customers only have access to general‑waste and mixed‑recycling bins, with no realistic composting route at all.

Eco Claims Checklist: 8 questions to stress-test your sustainability messaging before it goes live
Use this checklist to stress‑test the eco claims on your menus, website and signage before they go live.
✔ Is the claim literally true, and can you prove it?
Make sure you have data, certifications or supplier documentation to back up each claim — don't just repeat optimistic catalogue copy.
✔ Is it clear what the claim refers to?
Spell out whether you mean the cup, the main packaging, the lid, or only part of the system. "Cup made with 30% recycled plastic; lid made from virgin PP" is clearer than "fully recycled packaging".
✔ Are you hiding any important limitations?
If something is recyclable or compostable only in certain facilities, say so, and be honest if your local area doesn't collect that material from street or trade bins.
✔ Is the wording proportionate, or exaggerated?
Swap absolutes like "completely eco‑friendly" for more precise statements such as "uses less plastic than our previous cup and contains recycled material."
✔ Are comparisons fair and explained?
If you say "30% less plastic", clarify what you are comparing with — your previous packaging, a common alternative, or a specific benchmark.
✔ Does it reflect what actually happens in the UK, not just in theory?
Check that your claim matches the real recycling and composting options available to your business and how your customers actually dispose of the packaging.
✔ Is your story consistent across all channels?
Make sure your menus, delivery platform listings, website and social posts all use the same language for the same packaging, rather than calling it "compostable" in one place and "recyclable" in another.
✔ Do your staff know how to explain it and where to send waste?
Your team should be able to answer "which bin does this go in?" and "what does eco‑friendly mean here?" without guessing. If they can't, simplify either the claim or the waste system (or both) until it's easy to explain.
How CupsDirect helps you get it right
CupsDirect provides specific, evidence‑based product information so you know exactly what you can tell your customers with confidence - rather than leaving you to interpret vague, global marketing language from suppliers.
That means being upfront about where rPET cups, paper, bagasse and selected compostable lines are likely to end up, and what "better" really looks like in UK conditions.
