Closing the loop on PET plastics.

CataCycle develops scalable chemical recycling technology that converts difficult PET waste into virgin-quality recycled polyester with a significantly lower carbon footprint.

// The Problem

Lessthan20%ofPETisactuallyrecycled.

The 80% Problem

Less than 20% of PET plastic is currently being recycled — and even that fraction loses quality every cycle until it's worthless. The other 80% goes to landfill or incineration.

Mechanical Recycling's Ceiling

Conventional mechanical recycling cannot process colored PET, contaminated packaging, or mixed-grade waste. It degrades polymer chains with every pass, producing lower-quality output that cannot re-enter food-contact applications.

Chemical Recycling Closes the Loop

Chemical recycling returns PET to its molecular building blocks — monomers — and rebuilds it into virgin-equivalent material. No quality loss. No color restrictions. No contamination barrier. This is how the loop actually closes.

// About CataCycle

The Chemistry Is Ours. The Process Is Funded. We Are Scaling.

Less than 20% of PET plastic is currently being recycled — and even that fraction loses quality every cycle until it's worthless. The other 80% goes to landfill or incineration. CataCycle closes that loop.

Our process breaks post-consumer PET, including colored and hard-to-recycle grades that conventional recycling rejects, back down to its molecular building blocks and rebuilds it into virgin-quality rPET, indistinguishable from new material and suitable for food-grade packaging.

The process is metal-free, patented, and carries a significantly lower carbon footprint than existing technologies. The chemistry is ours. The process is funded. We are scaling.

For brands that have recycled content targets on paper but no viable supply chain to meet them, we are the answer.

// Our Process

From Waste to Virgin-Quality. The Chemistry Is Ours.

01 — Input

We accept post-consumer PET packaging waste — including colored, contaminated, and hard-to-recycle grades that conventional mechanical recycling rejects entirely.

02 — Depolymerization

Our patented, metal-free chemical process breaks PET down to its molecular building blocks — monomers. Clean. Precise. Repeatable at scale.

03 — Virgin-Quality rPET

The output is virgin-equivalent rPET — indistinguishable from new material, food-grade certified, and produced at a significantly lower carbon footprint than virgin production.

Chemical Recycling of Post-Consumer PET

We accept PET packaging waste, including colored and hard-to-recycle grades that conventional recycling rejects, and convert it into virgin-quality rPET at a competitive price and a significantly lower carbon footprint than virgin production.

Strategic Partnerships with Brands & Packaging Companies

We work with companies that have recycled content targets to meet and need a supply chain that actually delivers. If you are sourcing PET packaging at scale, we want to talk.

// Credibility & Stage

Funded. Proven. Scaling.

Scaling to Continuous Flow

CataCycle has completed proof-of-concept and is now in active scale-up phase, transitioning to continuous flow processing. The chemistry is validated. The process is funded. We are scaling.

The Market Is Ready

For brands that have recycled content targets on paper but no viable supply chain to meet them, we are the answer. The regulatory pressure is real. The demand is there. The supply chain gap is where CataCycle operates.

// What partners say

Trusted by the people closing the loop.

CataCycle is one of the few teams actually solving the supply gap for food-grade rPET. The chemistry is real, the team is credible, and they understand what brand owners need.

We have recycled-content targets we cannot meet with mechanical rPET alone. A partner that can deliver virgin-quality output at scale is exactly what the market has been waiting for.

Metal-free, continuous-flow chemistry on PET waste is genuinely differentiated. CataCycle is the most promising team we have evaluated in this space.
