Recycled polyester apparel is clothing made from polyester fiber that comes from reclaimed plastic, almost always post-consumer PET bottles, instead of new petroleum. For a marketing team, it is a practical way to put a lower-carbon material into branded tees, jackets and quarter-zips. The value depends on three things: the recycled content you specify, the paperwork behind it, and the words you use to describe it. This guide covers all three.

TL;DR

Recycled polyester (rPET) is polyester spun from shredded, melted and re-extruded plastic bottles, and 99% of recycled polyester in 2022 came from bottles.
Using bottles instead of new PET produces 75% fewer greenhouse gas emissions, according to the American Chemical Society.
Ask suppliers for GRS or RCS certification and the matching transaction certificates, not just a hang tag.
Under the FTC Green Guides, state the actual percentage of recycled content and avoid vague “eco-friendly” language.
Wash guidance on the label or in the kit insert helps recipients get the most from the garment.

What recycled polyester apparel actually is

Polyester is a plastic. Specifically, for textiles it almost always means polyethylene terephthalate, or PET, which The Guardian notes is the most common fiber on the planet and makes up over half of the overall fiber market. It is the same family of plastic used in water bottles, the ones marked with the number 1 in the recycling symbol.

That is why the swap works so well. The American Chemical Society explains the process: post-consumer bottles are shredded into flakes, melted into pellets, and extruded through spinnerets to form new fibers, which are then knitted or woven into fabric. The finished garment feels like any other polyester piece: light, strong, quick drying and wrinkle resistant.

The same ACS page gives a useful scale: about 9 plastic bottles go into one T-shirt. If you are ordering 500 tees, that is a concrete figure for your internal sustainability recap, as long as you confirm the real recycled content of the specific garment with your supplier first. Bottle counts vary with garment weight and blend.

Bottle-derived versus textile-to-textile

Two routes exist. Nearly all of today’s supply is bottle-derived. Pre- and post-consumer recycled textiles made up less than 1% of the global fiber market in 2022, per the same Textile Exchange materials report. Textile Exchange has said the industry should build out textile-to-textile systems over time, so expect more garments made from old garments in coming years.

For your buying today, the practical point is simple: when a supplier says “recycled polyester,” assume bottles unless the spec says otherwise, and describe it that way.

Why marketing teams choose it

Branded apparel is among the most visible items in a promotional program. It is worn at events, in offices and in photos. Choosing a recycled-content fabric lets the garment carry a specific, checkable story rather than a generic one.

The numbers behind that story are encouraging:

The ACS figure of 75% fewer greenhouse gas emissions compares bottle-derived polyester with making new PET.
A 2023 peer-reviewed study of sportswear cites the Higg Material Sustainability Index, which puts mechanically recycled polyester at a 70% lower greenhouse gas footprint than virgin polyester.
Recycled polyester was around 14% of all polyester produced globally in 2022, so choosing it puts your program on the side of a growing share of the market.

Note that the two emissions figures use different baselines and methods. Quote each one with its source and scope, never blend them into a single headline number.

Where it fits in a merch program

Recycled polyester suits the categories where polyester already performs best:

Performance tees and polos for events, field teams and running or charity programs.
Quarter-zips and fleece layers for onboarding kits and client gifts.
Jackets and vests for outdoor and sport programs.
Caps, bags and accessories where a recycled-content textile is part of the construction.

Cotton and blends still have their place. Textile Exchange cautions that fiber types should not be compared across categories because impacts depend on production systems and other variables. Pick the fabric that suits the garment and the audience, then document it well.

How to verify recycled content before you order

A tag that says “made with recycled materials” tells you very little. Ask for proof that matches the claim.

The certifications to look for

The Global Recycled Standard (GRS) and Recycled Claim Standard (RCS) verify recycled inputs and chain of custody. According to the Textile Exchange Supplier Certification Toolkit, each production stage from recycling through the last business-to-business seller must be certified, and certified products need scope certificates and transaction certificates.

For a buyer, that translates into a short checklist:

Ask which standard applies (GRS or RCS) and for the supplier’s current scope certificate.
Ask for the transaction certificate covering your specific order.
Confirm the recycled percentage of the garment, not just the yarn or one component.
Keep the documents in your campaign file so legal and brand teams can pull them later.

Questions for any apparel supplier

Question	Why it matters
What percentage of the fabric is recycled?	Required to make a qualified claim
What is the recycled source (bottles or textiles)?	Lets you describe the material accurately
Is the garment GRS or RCS certified, with transaction certificates?	Supports the claim with documentation
What is the full fiber blend (spandex, cotton)?	Affects the recycled percentage and care
Are decoration methods compatible with the fabric?	Protects print quality on performance fabrics

A good distributor will know these answers or will get them from the factory. Bring the list when you brief your account contact.

How to describe it without overclaiming

The FTC’s Green Guides are the US reference point. The FTC summary advises marketers to avoid broad, unqualified environmental-benefit claims, to qualify general claims with clear, prominent, specific benefits, and to state the percentage of recycled material. The guidance is dated October 2012, and it is worth checking the FTC page for the current version before a campaign launches.

Here is how that sounds in practice.

Weak: “Our eco-friendly team jackets.”

Stronger: “Team jackets made with 100% recycled polyester, from post-consumer plastic bottles.” (Use only if your documentation supports the exact percentage.)

Weak: “Saves the oceans.”

Stronger: “Made from recycled plastic bottles. Each tee uses about nine bottles.” (Check the bottle count with your supplier for your specific garment.)

A few more habits keep copy clean:

Name the percentage and the material every time.
Put the claim next to the product, not buried in a footer.
Say “recycled content,” not “recyclable,” unless you can support the second term.
Match web, packaging and sales deck wording so nobody contradicts the tag.

Care guidance that goes with the garment

Polyester sheds tiny fibers in the wash, as all synthetic textiles can. The EPA’s Trash Free Waters series notes that shedding is influenced by garment age, construction and chemical finish, and that washing full loads and washing less often can help reduce it.

That gives you a simple, useful care card to slip into a kit or add to an onboarding page:

Wash full loads, and wash only when needed.
Choose gentler cycles.
Keep the garment in rotation for years, since a well-made piece worn often is the most effective use of the material.

The Changing Markets Foundation makes the same broader point: buying fewer, better-quality garments, washing less and on gentler cycles are the habits that help most. For a promotional program, that is an argument for quality. A jacket someone wants to keep wearing outlasts a giveaway that ends up in a drawer. Choose cuts, colors and logo placements your recipients will actually wear.

A note on where the bottles come from

Bottle supply is not unlimited. In the US, NAPCOR found that producers decreased post-consumer RPET use by 27.6% between 2021 and 2023, to 496 million pounds, with the filament segment, which includes carpet and textiles, seeing the sharpest drop. Demand for the material moves with other industries, so lead times and availability for specific recycled-content styles can shift. The practical advice for a buyer is to start early on large programs and to build a backup style into your plan.

That is also where an experienced distributor earns its keep.

Perspective

Most teams we work with don’t ask us whether a garment is “green.” They ask whether it will arrive on time, look right with the logo, and survive a legal review of the copy. Recycled polyester answers all three when the spec is clear.

Our view is simple: treat recycled content as a specification, like size range or decoration method. Decide the percentage you want, ask for the documents, and write the claim from those documents. A precise line on a tag beats a big claim on a banner every time.

We built Discount Swag around curated quality from trusted suppliers, and around the operational side of large programs: rush orders without stress, delivery to one location or many, and branded kits that put several items in one box. If recycled-content apparel is part of your brief, bring us the spec and the deadline, and we will work it into the program.

A simple buying workflow

Use this order of operations for your next apparel project:

Define the goal. Event giveaway, onboarding kit, client gift or employee uniform each calls for a different garment and quantity.
Set the spec. Choose the fabric, the minimum recycled percentage, and the decoration method.
Request documentation. Ask for certification and transaction certificates when you place the order, not after delivery.
Approve the copy. Write product descriptions and campaign messages from the documents, using percentages and plain terms.
Plan the logistics. Decide whether goods ship to one warehouse or to many recipients, and set the delivery date with a buffer.
Add the care card. A short wash guide extends the life of the garment and keeps your brand on people longer.

FAQ

Is recycled polyester sustainable?

It has a lower greenhouse gas footprint than virgin polyester: the Higg Material Sustainability Index puts mechanically recycled polyester about 70% lower. Its overall impact still depends on the garment, how long it is worn and how it is washed. Describe it with specific, qualified claims rather than a blanket label.

Is polyester plastic?

Yes. Textile polyester is almost always PET, the same plastic found in water bottles, and it is made from petroleum or natural gas. Recycled polyester uses reclaimed PET, typically bottles, as its starting material instead of new raw materials.

How many bottles does it take to make a T-shirt?

The American Chemical Society says about 9 plastic bottles make one T-shirt. The real number varies with garment weight and fabric blend, so confirm it with your supplier before using it in marketing copy.

What certification should I ask for?

Ask for the Global Recycled Standard or the Recycled Claim Standard, with scope and transaction certificates. Textile Exchange’s toolkit explains that these verify recycled inputs and chain of custody, and that every stage through the last business-to-business seller must be certified.

Can I say my apparel is “eco-friendly”?

The FTC Green Guides advise against broad, unqualified environmental claims. Qualify the claim and state the percentage of recycled material, for example “made with 100% recycled polyester” when your documents support it.
