Summary
There’s a certain amount of cynicism developing around claims of certain big brands to be ‘environmentally friendly’ or ‘sustainable’.
Too many sustainability claims on packaging have been found to be paper thin when subjected to scrutiny, leading to accusations of greenwashing.
For brand marketing and compliance teams, the challenge is not just about choosing recyclable or compostable pouches. It’s about communicating their benefits accurately, responsibly and in line with UK regulations so consumers can feel genuinely comfortable with their purchase decision.
This guide explains how to write credible, honest on‑pack claims without slipping into greenwashing, helping you stay compliant while still building trust with consumers.
Why honest communication matters more today
Sustainable packaging has moved from a “nice-to-have” to an expectation. Retailers, regulators and consumers have become far more alert to vague or exaggerated claims.
The UK’s Competition and Markets Authority (CMA) and the Advertising Standards Authority (ASA) have both tightened guidance on environmental claims, meaning brands can no longer rely on soft language such as “eco-friendly” or “planet-safe” without robust evidence.
For marketing teams, this shift means adapting the language you use. For compliance teams, it means ensuring every claim can be backed up. For both, it means developing a joined‑up approach that keeps the business confident and protected.
Start with precise definitions
One of the most common sources of greenwashing is using terms that sound positive but have unclear meaning. Words such as “green”, “environmentally friendly”, “responsible” or “better for the planet” may feel reassuring, but they aren’t measurable.
On the other hand, terms with specific technical definitions are more authentic, especially when accurately applied to the pouch you’re selling.
For example:
- Recyclable: can the pouch be recycled through mainstream UK systems, kerbside or store drop‑off, or only through a specialist scheme? Each route needs different wording.
- Compostable: is the pouch certified for home composting, industrial composting, or both? These distinctions matter, as most UK homes don’t have access to industrial composting facilities.
- Biodegradable: it’s probably best to avoid this term unless legally required or scientifically supported, as it is often considered too broad to be meaningful.
Your packaging copy should focus on what is true today, not what will be true if a future recycling system improves.
Be clear about the disposal route
It is a mistake to assume customers know how to recycle or compost packaging. In reality, the opposite is true: uncertainty leads to contamination of recycling streams and mistrust of sustainability claims.
Instead of simply printing “100% recyclable”, pouches should offer advice to customers such as:
- “Recycle at large supermarkets with flexible plastic collections.”
- “Place in your home compost bin; breaks down under typical UK outdoor conditions.”
- “Industrial composting required. Check with your local council.”
This small shift makes claims more honest and more useful. It also reduces the risk of being accused of exaggerating the environmental benefit.
Avoid implying guaranteed environmental outcomes
Another common pitfall is implying that recyclable or compostable automatically means “good for the planet”. The ASA has ruled against brands that suggest their packaging will be recycled or will biodegrade, when the actual end-of-life outcome depends on consumer behaviour or local infrastructure.
Safer alternatives include:
- “Designed to be recycled where facilities exist.”
- “Certified for industrial composting.”
- “This pouch can be recycled through store drop‑off collections.”
These phrases state the potential without promising what will happen in every case.
Provide evidence without overwhelming the customer
Compliance teams may focus on certification, while marketing teams prefer simple messages. You can achieve both by using layered communication such as the following:
- Make the on-pack headline claim short, clear, and easy to understand.
- Keep the supporting text to a brief explanation, for example “Made from a mono-material for easier recycling.”
- Use a QR code to link to testing standards, lab reports or FAQs for customers who want more detail.
This approach will ensure transparency without cluttering the design or overwhelming the reader.
Explain the benefit without overstating it
You may want to highlight the advantages of choosing recyclable or compostable pouches, but it’s important to avoid language that oversells the sustainability benefit.
Avoid statements such as:
- “This pouch is 100% good for the planet.”
- “Compostable means zero waste.”
- “Recyclable packaging solves plastic pollution.”
Instead use statements such as:
- “This pouch uses a single material, making it easier to recycle in the UK.”
- “Certified home‑compostable and breaks down in typical outdoor conditions.”
- “Designed to reduce reliance on mixed plastics.”
These statements are accurate, clear and backed by the actual features of the material.
Avoid comparing your pouch to competitors without solid evidence
Environmental comparisons such as “greener than”, “less wasteful than” or “more sustainable than” require strong proof and the CMA expects claims to be based on full life-cycle data. Unless you have an LCA (Life Cycle Assessment) to back up comparative language, it’s safer to avoid it completely.
If you want to talk about improvement, frame it as your own brand’s progression, not a comparison with others with phrases like:
- “This pouch uses 30% less virgin plastic than our previous packaging.”
- “Our new format reduces material use by 25% compared with last year.”
These claims are measurable and can be independently verified.
Conclusion: Clear, evidence-based copy earns consumer trust
Talking about recyclable or compostable pouches doesn’t need to be complicated, but it does need to be accurate.
When you choose precise language, explain disposal routes properly and avoid over‑promising on environmental benefits, your packaging becomes both compliant and credible.
