There's a packaging problem in the coffee industry that most brands don't talk about, because talking about it means admitting their own packaging probably has it too.
Most coffee bags, including a lot of ones proudly labelled "recyclable," are made from multiple layer laminates. That typically means a barrier film, a foil or metallised layer, and an outer plastic layer, all bonded together into a single piece of packaging. It's brilliant at keeping coffee fresh. It is, in almost all cases, impossible for standard recycling facilities to actually process. That's not a minor technicality. It's the difference between packaging that behaves like it's recyclable and packaging that actually is.
The Problem With Multiple Material Packaging
Recycling facilities sort waste by material type: plastic here, foil there, paper elsewhere, using processes that separate materials based on their physical and chemical properties. When a single piece of packaging is made of three or four bonded layers of different materials, there is often no cost effective way to pull those layers apart at scale. The result is that a huge proportion of packaging that only looks recyclable in the coffee category ends up in general waste, regardless of the symbol printed on the back.
This is the gap between a recyclability claim and recyclability in practice, and it's one of the more quietly significant sustainability issues in food packaging today.
What Monomaterial Actually Means
Monomaterial packaging is built from a single material, commonly a single type of polyethylene (PE) or polypropylene (PP), engineered to still deliver the barrier properties (oxygen protection, moisture resistance, freshness) that coffee needs, without laminating multiple material types together.
Because it's one material throughout, it can go through standard plastic recycling streams in a way multi material laminates simply can't. It's a genuine, structural improvement, not a labelling change.
Why We're Making the Switch, Wherever Possible
We're moving Siren Grounds packaging to monomaterial formats wherever the format allows it. We're saying "wherever possible" deliberately, because we'd rather be precise about where we've made the change than make a blanket claim that doesn't hold up under scrutiny. Some formats, particularly where extended shelf life or specific barrier requirements are critical, take longer to transition safely, and we're not willing to compromise product freshness or safety to hit a marketing deadline.
But everywhere the technology allows it, we're making the change. It's not the most exciting sustainability story we could tell. There's no dramatic before and after. It's a materials science decision, made quietly, product line by product line.
Why This Matters More Than a Claim on a Bag
We'd rather make the boring, correct decision than the exciting, hollow one. A recycling symbol that doesn't reflect what actually happens to your packaging isn't a small inconsistency. It's the kind of gap that, multiplied across an entire industry, is a meaningful part of why flexible packaging recycling rates remain so low.
Choosing monomaterial packaging wherever possible isn't a campaign. It's a standard we're building the rest of this brand on.
