Material · recycled PET resin
Built from VerdiPTA, our terephthalic acid recovered from the waste others reject: soiled textiles, coloured and opaque bottles, and multilayer packaging.
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: soiled textiles, multilayer packaging, and the coloured, opaque PET bottles that mechanical recyclers reject. We recover the terephthalic acid, purify it to virgin-equivalent grade, and polymerise from there. New supply rather than reallocated supply.
The spec
Both the monomer and the PET chip are measured, on lab and pilot batches. VerdiPET is at pilot stage, and every grade was polymerised alongside a virgin control.

Validation data
IV decides what a PET chip can become. Ours lands on or above the virgin control at every grade we make.
IV is a direct read on molecular weight, and molecular weight sets the grade: about 0.65 for yarn, 0.70 for fine denier, 0.84 for bottles. Mechanically recycled PET loses IV with every pass through an extruder. VerdiPET is built to it, from the monomer up.
VerdiPET is made the way a virgin producer makes PET, and it lands close to the virgin control polymerised alongside it. Colour is the main difference: a warm, darker base suited to dope-dyed, tinted and darker products. We publish it rather than hide it.
Full chip data for all three grades is on the TDS, shared on request.
The PET loop
PET is made from terephthalic acid and MEG. 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- and bottle-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. Full grade detail is not published here; the TDS is available on request.
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.
Bottle-derived rPET is remelted flake, and it loses IV with every pass through an extruder. VerdiPET is rebuilt from monomer purified to virgin-equivalent grade, and its IV lands on or above the virgin control at every grade we make.
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 MEG 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.
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.
