Textiles · VerdiPTA™ + VerdiFLO™
We recover terephthalic acid from the worst mixed textiles on earth - torn, soiled, headed for landfill - purify it past industrial-grade virgin, and polymerise it into yarn that spins on existing equipment.
The gap nobody wants to talk about
The industry makes around 100 million tonnes of fibre a year and more than 60% of it is polyester - petroleum derived, energy intensive, and at end of life almost entirely incinerated or landfilled.
Mechanical recycling downgrades the quality. Bottle-to-fibre solves a fraction of the problem and takes feedstock from another loop that needed it. And mixed fabrics - polycotton blends, soiled rejects, torn garments - are treated as unrecyclable full stop. That last category is where we start, on purpose, because nobody is competing for it.
How it works
The same VerdiCycle reactor that turns chip packets into polyolefins depolymerises mixed textile waste at 80-120°C in water, with no organic solvents.
Chemo-mechanical depolymerisation at 80-120°C and 1-2 ATM, water-based. Alkaline hydrolysis at near-atmospheric pressure, where glycolysis and methanolysis routes typically need 200-250°C and high pressure.
A patent-pending purification step that avoids recrystallisation entirely. 4-CBA - the impurity that caps chain length during polymerisation - comes out below instrument detection.
VerdiPTA plus mono-ethylene glycol gives recycled PET. Our first polymerisation run hit 0.654 dl/g intrinsic viscosity - inside the yarn-grade window, first attempt, with no formulation tuning.
VerdiFLO spins on virgin polyester equipment with no process re-tuning. Faze3 have completed spinning trials.
Roughly 60% of the feedstock goes to VerdiPTA and the remaining 40% becomes VerdiMIX construction composite. Zero waste out the back.
If you polymerise yourself, we supply VerdiPTA and stay out of your process. Plenty of partners want exactly that.
The monomer
| Parameter | Virgin PTA (petrochemical) | VerdiPTA |
|---|---|---|
| Purity | 99.5 - 99.9% | 99.5 - 99.9%, 99.6% typical |
| 4-CBA, the critical impurity | 20 - 36 ppm | Below detection |
| p-Toluic acid | 100 - 170 ppm | 40 ppm |
| b* value | 0.71 | 0.51 |
| rPET IV once polymerised | 0.661 dl/g | 0.654 dl/g, against a 0.640 ±0.01 yarn spec |
4-CBA is the one that matters. It caps growing polymer chains, and even low-ppm residuals stop you reaching yarn-grade molecular weight. Everything downstream depends on that single number.
The yarn
Polymerised from our own VerdiPTA. It matches virgin PET chemistry closely enough to spin on virgin polyester equipment with no process re-tuning, which is usually the sticking point.
Around 70% recycled, and we will not call it 100%. The recycled TPA is roughly 70% of the PET by mass; the MEG is still virgin. A bio-MEG route is on the roadmap and we will say so when it lands, not before.
One feedstock, four routes
Where this actually is
Every figure on this page comes from lab-scale batches. The polymerisation result came from a partner-operated pilot, not our own bench.
Scaling the purification and tightening batch-to-batch consistency. That consistency is the honest weak point, and it is the work.
The first tonne of VerdiFLO due before the end of the year. Faze3 spinning trials are already complete.
Colour correction via optical brighteners, deeper purification, and crystal consistency at demo-plant scale.
The textile line sits inside the commercial plant at marginal extra capital cost, because it shares the VerdiCycle reactor, the thermal oil system and the controls.
We start from soiled, blended, mixed textile waste - the fraction that defeats mechanical recycling - and still reach monomer purity with full physical traceability.
Before you ask
Yes. VerdiFLO matches virgin PET chemistry and spinning behaviour closely enough to run with no process re-tuning. Faze3 have completed trials on standard equipment.
No, and we will not say it is. Around 70% - the recycled TPA is roughly 70% of the PET by mass and the MEG is still virgin. A bio-MEG route is on the roadmap.
Torn, soiled, mixed textile waste. Polycotton blends, garment factory rejects, soiled rags that would otherwise be incinerated. We process them as they are, which is the whole point.
Yes. Plenty of partners want VerdiPTA and their own polymerisation. We supply the building block and stay out of your process.
We are at pilot scale - 100 kg/day - with the first commercial tonne of VerdiFLO due December 2026. If you need volume before then, tell us the number and the date and we will be straight about whether we can meet it.
Yes. Both raw white and dope-dyed spun yarn are confirmed. Dope dyeing also skips the water and energy of conventional dyeing.
Roughly 40% of the feedstock becomes VerdiMIX, a construction composite. Nothing goes to landfill from our side.
Lab scale, 2L to 50L batches, stated as such. Independent validation and commercial-scale consistency are still in progress. We publish data as it is, not as we would like it to be.
We are looking for yarn manufacturers, fibre producers and material processors to work with at the frontier of this. Early, honest, and built on shared R&D. If you have the downstream capability and we have the feedstock, there is a conversation worth having.
Not a sales call. Bring your spec, your IV window and your volumes, and we will tell you what we can and cannot do yet.
