Project Regen


The Problem
Industrial waste still holds value — but current systems destroy it.
Each year, thousands of tonnes of chemical and treated waste are disposed of at high cost to industry and the environment. Traditional disposal methods — neutralisation, landfill, or incineration — eliminate potential value while increasing operational and compliance risk. Regen was built to change that.
The Solution
Recover usable materials from complex waste streams.


Regen combines advanced filtration, centrifuge separation, ionic flocculation, and multi-stage treatment to recover valuable compounds from chemical and timber waste.
By turning hazardous residues into reusable resources, Regen reduces disposal volumes, creates new product streams, and transforms waste management into a source of profit.
“Regen makes circular recovery not just possible — but commercially viable.”
How it Works
Industrial waste still holds value — but current systems destroy it.


Regen’s recovery architecture is engineered for integration.
Each stage of the process can operate as a standalone module or a continuous system, allowing deployment across timber, agriculture, and manufacturing operations.
Pilot Program 1
Validating technology. Proving scalability.
Regen Pilot 1 focussed on CCA (Copper, Chromium, Arsenic) timber waste, one of New Zealand’s most persistent industrial contaminants.
The system is currently operating at pilot scale to test recovery efficiency, product quality, and throughput performance.
Pilot Site: South Island, New Zealand
Initial Focus: CCA timber treatment waste
Target Output: Recovered chemical compounds for reuse
Performance Indicators: Purity, yield, cost per litre, and scalability

Pilot 1, as of Feb 2026 has generated strong results and continued validation of this circular solution:
PILOT 01
200T DIVERTED
> 40% RECOVERED
80T RETURNED
Market Impact
Waste reduction with measurable economic return.

Regen offers tangible benefits for primary industries, councils, and regulators:
Reduces landfill dependence and disposal costs
Recovers saleable materials for reuse
Decreases environmental liability
Strengthens compliance with national waste minimisation goals
The recovered compounds feed directly into New Zealand’s circular chemical economy, replacing imported materials with locally reclaimed resources.
What’s Next
Expanding recovery across waste types and regions.
Following the success of the CCA pilot, Regen is expanding into glycols, solvents, washwater, and all other preservative systems. We'll continue developing additional Regen skids for organic streams and for further refinement of recovered feedstocks.
Each pilot builds on the same recovery framework — refining, scaling, and integrating into regional waste infrastructure.
Together, they form the foundation of Graymark’s vision: a national circular recovery network.
We’re currently engaging with timber processors, agricultural, horticultural and viticultural operators, councils and local government interested in recovery partnerships, pilot participation, and technology integration.
