Recovery infrastructure, built into a container.

Regen is Graymark’s separation-first recovery platform. It strips the target contaminant from the host material, collapses tonnes into drums, and closes every job with independent verification — at our Nelson facility, or deployed to your site in days.

THE PLATFORM

One core, fitted to every stream.

Regen is not a fixed plant. It’s a containerised separation train, configured to the chemistry of the stream in front of it. The same core that washes a contaminated soil re-concentrates a treatment chemical or strips a metals-laden liquor.

Containerised

The full treatment train ships as containerised plant. No fixed infrastructure, no consenting a permanent facility on your land.

Built in Nelson

Designed, assembled and proven at our Whakatū Nelson facility, where the platform runs commercially now.

Facility or Site

Small streams travel to us. Large volumes don’t have to: Regen deploys to your site in days and leaves when the job is done.

Fitted to the Chemistry

Mechanical first, chemical second. Each deployment carries the separation stages the target chemistry demands — nothing it doesn’t.

THE PROCESS

Tonnes in. Drums out.

01

Characterise

Independent laboratory characterisation before anything moves. The chemistry decides the treatment train, the price, and the verification plan.

02

Separate

Mechanical separation divides the bulk; targeted chemistry strips the contaminant from the host material. 90 to 99.9%+ of the target fraction, in a single pass.

03

Concentrate

Hazardous mass collapses by up to 1,000 to 1. The host material leaves as clean soil, water or process material. The contaminant leaves as drums of concentrate.

Close the Loop

Recovered chemistry returns to the industries that run on it. The residual is managed onshore. Independent verification closes the file.

THE CHEMISTRY

The chemistry decides the treatment.

Four classes of contamination cover almost everything New Zealand buries. Regen targets the class, not the bulk — and on the right chemistry, contaminants leave below laboratory detection.

Heavy Metals

Arsenic, copper, chromium, lead, boron.

Arsenic, copper, chromium, lead, boron.

POPs

Organochlorines, PCBs, DDT, dieldrin, lindane.

Mixed & Complex Streams

Sludges, leachates, hydrocarbons, tars, glycols. Multiple contaminants, any state

IN OPERATION

Every batch measured. Every unit watched.

Adaptive Dosing

Every incoming stream is chemically different. Regen calibrates reagent dosing to the measured chemistry of each batch before processing begins.

Remote Monitoring

Throughput, discharge quality and system performance are tracked continuously across every deployed unit, with remote-operation capability.

Fully Auditable

Every batch is logged against its stream characterisation, so the processing record reconciles with the mass balance at close-out.

THE STREAMS

The streams are just how it arrives.

Contaminated Soils

Transformer Oils & Electrical Wastes
PFAS-impacted Soils, Waters & Media
Industrial Liquids, Washwaters & Leachates
Blast Media & Marine Residues
Chemical stock, tanks & IBCs
Mine Waters & Extractive Residues

DOCUMENTATION

A file your team can follow.

Every job closes with the documentation to prove it: stream characterisation, chain of custody, processing record, independent laboratory verification, and a reconciled mass balance.

All independent testing work is carried out by the best IANZ-accredited laboratories.

The numbers reconcile or the job is not done.

The capability runs commercially now, anchored in primary industry, where treatment plants and mills generate the country’s most concentrated hazardous streams.

VERIFIED OUTCOME

Legacy agriculture soil. Metals and pesticides, one pass.

A stockpiled soil from a former agricultural site carried the classic legacy signature: arsenic, lead and organochlorine pesticides including dieldrin and DDT. Co-contamination like this normally forces a choice between two bolted-together technologies or the landfill. Regen achieved:

99.96%

Dieldrin removal in a single pass

Non-detect

Full pesticide suite to non-detect

7 days

Sample to independent certification

Every job closes the same way. Independent laboratory verification, reported as mass balance.
