We recover terephthalic acid from the worst mixed textiles on earth - torn, soiled, headed for landfill - purify it to virgin-grade, and supply it to yarn manufacturers ready to close the polyester loop.
The global textile industry produces around 100 million tonnes of fibre a year. Over 60% of that is polyester - petroleum-derived, energy-intensive, and at end-of-life, almost entirely incinerated or landfilled.
Mechanical recycling downgrades quality. Bottle-to-fibre only solves a fraction of the problem. And mixed fabrics - the polycotton blends, the soiled rejects, the torn garments nobody wants - are effectively considered unrecyclable.
Using our patented VerdiCycle process - the same chemo-mechanical chemistry we use for multilayer plastic - we depolymerise post-consumer, rejected mixed textile waste at 80 - 120°C, without organic solvents, to recover crude terephthalic acid, which we then purify to virgin equivalent-grade.
We then supply that PTA(purified) - under the VerdiPTA brand - to yarn manufacturers and material processors working to close the polyester loop.
Chemo-mechanical depolymerisation of mixed textile waste at 80 - 120°C, 1-2 ATM, water-based. Same VerdiCycle reactor as our MLP line.
Patent-pending purification step that doesn't use recrystallisation. Critical impurity 4-CBA - the impurity that breaks polymer chains during polymerisation: below detection.
PTA delivered to yarn manufacturers, fibre producers, and material processors. Ready for polymerisation.
We don't spin yarn. We don't weave fabric. We make the building block that your process needs.
Torn, soiled, mixed textile waste. Polycotton blends. Garment factory rejects. Material that has no viable end-of-life path today.
Hover for detail ↓Sources include post-consumer apparel rejected by mechanical recyclers, garment factory trims, and soiled rags typically incinerated. Polycotton blends are notoriously difficult for existing recyclers - we process them as-is.
80 - 120°C, 1-2 ATM, water-based. No organic solvents. Patent-pending purification - no recrystallisation.
Residual becomes VerdiMIX. Zero waste.
Hover for detail ↓Alkaline hydrolysis in aqueous media. Operates at near-atmospheric pressure unlike competing glycolysis or methanolysis routes (which typically need 200-250°C and high pressure). Patent-pending purification avoids energy-intensive recrystallisation while hitting below-detection on 4-CBA.
Purified terephthalic acid, tested to polymer-grade specifications. Ready for polymerisation into recycled PET yarn, recycled PBT, DOTP, or recycled BHET monomer.
Hover for detail ↓Pilot-scale polymerisation trials achieved IV ≥ 0.654 dl/g on first attempt - comfortably inside polymer-grade yarn specifications. Packaging, logistics and batch documentation handled by our team.
Our first polymerisation attempt hit yarn-grade intrinsic viscosity. That's the bar we're working from.

VerdiPTA is currently at pilot stage. The current product meets polymer-grade requirements, but there's room for improvement - we're actively working to refine the process and tighten product consistency. If you're a yarn manufacturer or material processor interested in an early-stage supply partnership, we want to hear from you.

Polymerising VerdiPTA with mono-ethylene glycol yields recycled PET suitable for textile filaments, staple fibre, and packaging resin. This is where closing the polyester loop has the biggest volume impact - every kilogram of yarn spun from textile waste displaces virgin polyester.
We're especially interested in partnerships with polyester spinners, weavers, and brand-direct textile innovation teams ready to integrate circular polyester into their supply chains.
PBT (polybutylene terephthalate) is the go-to engineering plastic for automotive connectors, electrical components, and precision-moulded parts. Combining VerdiPTA with 1,4-butanediol yields recycled PBT with virgin-like performance - a material traditionally made entirely from petrochemical feedstocks.
The value density is much higher than rPET, making this commercially attractive even at modest volumes. Early conversations with automotive Tier 1 suppliers are open.
DOTP (dioctyl terephthalate) is the leading phthalate-free plasticiser for flexible PVC - flooring, cables, medical tubing, toys, automotive interiors. Demand is growing aggressively as phthalate regulations tighten in the EU, US, and India.
VerdiPTA is a direct drop-in for the DOTP synthesis route. For plasticiser manufacturers, this is a way to offer a genuinely circular, non-phthalate product without changing existing production lines.
BHET (bis-hydroxyethyl terephthalate) is the intermediate monomer used by some chemical recyclers for further processing. Supplying VerdiPTA-derived BHET unlocks a modular downstream route where partners can polymerise, re-depolymerise, or reformulate on their own timelines.
Useful for R&D groups, advanced recycling operators, and any partner building a multi-product pipeline from a single TPA source.
VerdiCycle isn't a single-trick process. The same chemistry that turns chip packets and sachets into recycled polyolefins also extracts TPA from mixed textiles. We built the textile line into our commercial plant at marginal CAPEX - not as a separate bet, but as proof that the platform scales across waste streams.
EU textile EPR regulations are tightening. Brands are looking for verified, traceable recycled content that actually closes loops - not mass-balance accounting. The supply of truly circular textile feedstock is near zero.
We're working with partners to change that.
We're looking for yarn manufacturers, fibre producers, and material processors who want to work with us at the frontier of textile circularity. This is a pilot programme - early, honest, and built on shared R&D. If you have the downstream capability and we have the feedstock, let's talk.
VerdiPTA for textiles is at pilot stage. Performance data reflects lab-validated results at 2L-50L scale. Independent validation and commercial-scale consistency work is ongoing. We share data as it is, not as we'd like it to be.
