Material · recycled PET resin
Made from coloured, opaque PET bottles and polymerised from our own VerdiPTA: terephthalic acid we recover from multilayer plastic.
Why it is different
Bottle-to-bottle recycling works. But it also means the recycled PET market competes for a feedstock that already had a functioning loop, so the more rPET a brand buys, the tighter that supply gets for everyone.
VerdiPET starts somewhere else: multilayer plastic, and the coloured, opaque PET bottles that mechanical recyclers reject. We recover the terephthalic acid, purify it past industrial-grade virgin, and polymerise from there. New supply rather than reallocated supply.
And it makes a dent in the 99%+ of this waste that never gets recycled.
The spec
The monomer data below is measured. The resin data is not published yet. VerdiPET is at pilot stage and we would rather leave a gap than fill it with an estimate.

What is known today
Where we stand today
Measured values are on the TDS, shared on request.
Validation data
Purity alone does not tell you whether a monomer will polymerise. The impurity profile does.
It is where we are furthest ahead of virgin, and it is the metric that makes or breaks everything downstream. It sits below instrument detection in our monomer, and it is present in every petrochemical PTA on the market.
Intrinsic viscosity is a direct read on molecular weight. Below the window, fibres break during drawing; above it, melt processing gets difficult. Landing inside it on a first attempt is the result, not the number itself.
The PET loop
PET is made from an acid and a glycol. VerdiCycle recovers both.
Purified terephthalic acid, in line with virgin on purity and better than virgin on the impurity that matters. Roughly 70% of the input by mass, and the half that is working.
Mono-ethylene glycol, recovered from the same reaction. Real, and at lab scale. Closing this side is what would take VerdiPET toward fully recycled.
Which is why the number is ~70% and not higher. Yarn-grade intrinsic viscosity proven on that route.
Extruded into film for flexible packaging, the format that starts most of this waste in the first place, and the one with the least recycled content in it today.
The other route out of the same polymer. Grade detail is not published yet. Ask us and we will tell you where it actually is.
It re-enters VerdiCycle and returns to monomer. No downcycling at the end of the loop.
Before you ask
Not at volume. VerdiPET is at pilot stage. If you want to be an early development partner, that is exactly the conversation to have now, with your eyes open about the stage.
On the monomer we are cleaner than industrial-grade virgin on the impurity that matters most. On the resin we have not published a comparison yet, and we are not going to imply one.
That is the design intent. Because we take PET back to its monomer and repolymerise it, VerdiPET follows the same route virgin PET takes to food-contact approval. Verification is under way, and we will not claim it before it is tested.
The glycol half of PET, recovered from the same reaction. It is at lab scale, so no, not yet. It matters because it is the thing that would take VerdiPET from ~70% recycled toward fully recycled, and we would rather you knew it existed and was early than found out later.
VerdiPTA is the monomer: purified terephthalic acid. VerdiPET is the polymer made from it. If you polymerise yourself, buy the monomer; if you want resin, buy VerdiPET. Both live on this page now. The validation data above is the monomer's.
Same monomer, polymerised and spun into yarn instead. One chemistry, several products, depending on where you sit in the chain.
If you convert PET and you want a feedstock that is genuinely additional rather than reallocated from another loop, let's talk.
