Recycled Polyester Is Still Plastic. Cork Never Was

Walk down the cosmetic bag aisle in any department store and one word keeps turning up: recycled. A premium Australian lifestyle brand builds it into the product name itself, selling "recycled polyester" cosmetic cases with 100% recycled polyester outers. Discount-store versions print it on the bag — "made from a minimum of 90% recycled polyester from post-consumer waste." Australia's biggest online fashion retailer even lists "Recycled Polyester" as a filter for toiletry bags, sitting in the same menu as PU and PVC.

At CORKSTORE, we work with a material that has never needed that word to sound good. So it's worth pulling apart what "recycled" actually means on a cosmetic bag — because it isn't what most people assume.

It's bottles, not textiles

Almost every "recycled" cosmetic or toiletry bag on the market is rPET — plastic drink bottles, melted down and re-spun into polyester fibre. It isn't recycled from old clothing or fabric offcuts; textile-to-textile recycling still covers less than 1% of clothing material worldwide, because the technology to do it at scale barely exists. The industry reaches for bottles because they're cheap and plentiful, not because they're the most sustainable option available.

And rPET is still plastic, full stop. It sheds microplastics for its entire life, takes anywhere from 70 to 400 years to break down, and its manufacture involves chlorine bleaching along with antimony trioxide and BPA — worth pausing on for a bag that sits in a warm, humid bathroom right next to the products you put on your skin.

This is exactly where cork earns its keep. It comes from the bark of the cork oak, harvested without felling the tree, which regenerates the bark every nine to twelve years. No bottles, no bleaching, no microplastic shedding — just a material that was renewable and biodegradable long before "circular economy" became a marketing phrase. Recent market research values the global sustainable cork leather category at roughly USD 1.35 billion in 2025, growing at over 8% a year, precisely because more brands and consumers are looking past bottle-based "recycled" claims toward materials that don't need the caveat.

Even the best version of the claim is still open-loop plastic

To be fair, some brands do this well. One certified B Corp accessories label builds its entire toiletry range around a detailed, well-documented recycled-materials story — PET bottles, industrial nylon offcuts, fishing nets, named proprietary weaves. It's the most credible version of the claim you'll find in the category.

It is still, however, open-loop plastic. PET bottles can be recycled three or four times into new bottles in a genuine closed loop. Once that plastic is diverted into a zippered, coated, multi-material washbag, it can never go back into that system — and the finished bag itself can't be recycled either. Tellingly, that same brand also uses MIRUM®, a genuinely plastic-free plant-based leather, elsewhere in its range. The alternative exists. They know it exists. Leading with bottles anyway is a choice, not a limitation.

We didn't need the bottle count

We use cork because we don't use plastic — not "less plastic," none. Sydney-based, woman-owned, PETA-approved vegan since 2012 and a Certified B Corp, James&Co built CORKSTORE around FSC-certified natural cork, alongside washable paper, eco canvas, organic cotton and next-generation plant leathers like MIRUM®. None of these materials need a bottle count to justify themselves. They're renewable at the start of life and biodegradable at the end — which is what circularity is actually supposed to mean, rather than a percentage printed on a swing tag.

Before you buy a "recycled" cosmetic or toiletry bag, ask three questions: what is the fabric, really — if the answer is rPET, recycled polyester or recycled nylon, it's plastic. Where did that recycled content come from — if it's bottles, it was pulled from a closed loop that could have kept reusing it. And can the finished bag, zips and coating and lining included, actually be recycled at the end of its life? It can't.

The recycled tag doesn't make a bag sustainable. The absence of plastic does far more — and cork never had to borrow the word to prove it
