Switching to sustainable packaging is easy. Switching to a supplier you can actually rely on is the hard part. We see the same pattern with cafés and takeaways all over Ireland: owners order eco packaging on a whim, it doesn't arrive on time or doesn't do the job, and they end up going back to what they used before.

This guide is about avoiding that. How to score a supplier, what to ask, and which green claims deserve a second look.

Start With Your Own Numbers

Before you contact anyone, know what you're buying. Otherwise every quote looks reasonable. Get these together first:

  • Your top 10 disposable items by volume
  • What you pay now, per item rather than per case
  • How much storage you have for bulk stock
  • Your busiest trading days, so deliveries land at the right time
  • What your bin collection accepts

That last one matters more than people expect. Compostable packaging only does its job if it ends up in a food waste or compost collection, so check your waste contract before you buy.

How to Score a Supplier

Rate each supplier from 1 to 5 on:

  • Delivery speed to your address
  • Stock consistency across repeat orders
  • Clarity of material and certification details
  • Bulk pricing at your volume
  • How easy it is to switch your account over

Anything scoring below 3 on delivery should be ruled out, whatever the price. A cheap case that arrives Tuesday is no use when you needed it Saturday, and a supplier who can't reach you next day will have you buying emergency packs at retail prices.

Questions to Ask Before You Commit

  • What is your cut-off time for same-day dispatch?
  • Do you deliver nationwide, or only to certain counties?
  • What is the minimum order for free delivery?
  • Can you supply spec sheets and certification documents for each product?
  • What happens if a case arrives damaged?

A supplier that answers all five without hesitation is worth keeping. For the record, here's where we stand at DiscountTillRolls.ie: orders placed before 1pm, Monday to Friday, leave our Dublin 12 warehouse the same day, we deliver right across Ireland, and our catering lines come with free delivery and our 150% Price Guarantee.

Checking the Green Claims

Most of the vetting comes down to one question: can the supplier back up what's on the box? The documents worth asking for are:

  • FSC certification for paper and board products
  • EU food contact compliance for anything that touches food
  • A named compostability standard, such as EN 13432, for anything sold as compostable

If the answer is vague, or the claim is just "eco" with nothing behind it, treat that as your answer. Our guide to compostable vs biodegradable vs recyclable explains what each label should mean.

This matters for you too if you sell to the public. Since 27 September 2026, EU rules on environmental claims (Directive 2024/825) mean green claims on your menus, signage and website need to be specific and capable of being backed up. If your supplier can't back a claim up, neither can you. This is general information, not legal advice.

Red Flags to Watch For

  • "Biodegradable" or "eco-friendly" with no standard or timeframe attached
  • No spec sheet available, or one that doesn't name the material
  • Bioplastic cutlery or plates sold as a way around the single-use plastics ban. Plant-based plastic still counts as plastic under those rules
  • "Compostable" claims with no advice on which bin the item goes in
  • Prices that only work if you order far more than you can store

Test With Samples Before You Switch

A compostable box that leaks is worse than the one it replaced. Order small quantities or samples of your main lines first and test them on a real service, not just on the counter.

Things worth testing: does the box hold up under grease and heat, does the lid close properly, does the cutlery survive a chicken wrap. As a reference point, these are the kinds of lines we'd suggest testing first:

Don't switch everything at once, either. Start with the two or three items that make up most of your volume, get them right, then move on.

Frequently Asked Questions

How do I know if a catering supplier is genuinely sustainable?

Ask for the documents behind each claim: FSC certification for board, EU food contact compliance, and a named compostability standard such as EN 13432. A supplier that can tell you exactly what each item is made from, and back it up on paper, is easier to trust than one relying on vague green wording.

What should I ask a new packaging supplier before ordering?

Ask about the same-day dispatch cut-off, whether they deliver nationwide, the minimum order for free delivery, whether they can supply spec sheets and certificates, and what happens if a case arrives damaged. Clear, quick answers to all five are a good sign.

Is bioplastic cutlery allowed under the single-use plastics rules?

No. Under the EU Single-Use Plastics Directive, which Ireland has implemented, plant-based and bio-based plastics still count as plastic, so bioplastic cutlery and plates fall under the same ban as conventional plastic. Paper cutlery and unlined bagasse plates are the usual alternatives.

Should I switch all my packaging at once?

Usually not. Start with the two or three items that make up most of your volume, test them on real service, and move the rest over once those are working. Switching everything at once tends to leave you with stock that doesn't suit your menu.
