Treated timber residuals: Regen in operation

Regen is live and processing treated timber residuals on site. After months of design, laboratory validation and calibration on real material, the system is running commercially, and the first stream through it is the one the timber treatment industry has struggled with longest.

Why timber residuals first

Timber treatment runs on copper, chromium and arsenic. The sludges, drip-pad washings and filter cake that come off a plant hold all three, and the usual pathway has been to stabilise the residual and bury it in a Class 1 landfill under the waste disposal levy. The treatment chemistry, which the plant paid for, goes into the ground with it.

What Regen does with it

The treatment chemistry is recovered and credited back where it meets specification. What cannot be reused leaves as a small, defined concentrate. The clean fraction is tested by an independent laboratory before it goes anywhere. Early results confirmed strong recovery and the purity the plant needs to take chemistry back.

“Our goal has always been to make environmental progress industrially viable,” said Mark Vinsen, Graymark CEO. “This is proof that recovery can outperform traditional waste management, economically and environmentally.”

What comes next

Treated timber residuals are the first of several streams Regen is taking as standing work. Glycol recovery follows. If you run a treatment plant, a galvanising line or a chemical process and you are paying to bury residuals, send us a sample.
