Founded in 1997.
Rebuilt for what comes next.

↓

Graymark was founded by Graham and Mark Vinsen in Auckland, New Zealand. For nearly three decades, the family has built, operated, and exited hazardous waste recovery businesses.

That operating history is the foundation. Every system we build, every process we design, and every deployment we run is informed by tens of thousands of hours working inside the waste streams we now recover.

In 2025, Graymark launched its first Regen unit — a containerised chemical recovery engine that does what no prior system in this market has done: process hazardous waste on-site and return recovered feedstock to industry. The technology is new. The knowledge behind it is not.

Approach

Product company. Not a services company.

Product company. Not a services company.

Product company. Not a services company.

Graymark funds its own R&D and delivers finished, operational systems. We identify waste streams that have recoverable value, build the machines to extract it, and deploy them into industry.

Every platform is designed for containerised deployment, multi-stream processing, and rapid iteration. A new waste stream goes from characterisation to live processing in weeks. A new site goes from assessment to deployed unit in days.

We control the full stack — chemistry, hardware, controls, deployment, operations. No subcontractors on the core process. No dependency on third-party IP.

Operations

From Nelson NZ to the World.

Graymark's R&D and central processing facility operates from Nelson, at the heart of New Zealand's forestry and primary industry corridor. Deployed units are shipped to customer and project sites across the country.

The waste streams we target — timber treatment chemicals, contaminated soil, industrial solvents, process residues, metal fractions — exist at scale in every country with primary industry. The platform architecture is designed to lift and shift internationally.
