Treatment residuals
Sludges, washings, filter cake, rags and tank bottoms from timber treatment, galvanising, plating and chemical processing.
Every treatment process leaves something behind. Timber treatment plants produce sludges, drip-pad washings and filter cake carrying the copper, chromium and arsenic they run on. Galvanising and plating lines produce metal-laden rinse sludges and spent baths. Chemical processors accumulate tank bottoms, rags and off-spec batches. These residuals arrive by the drum and by the IBC, every month, for as long as the plant runs.

Treatment plant maintenance and decommissions
Stabilise and bury. The residual is blended with binder until it passes landfill acceptance criteria, then goes to a Class 1 landfill under the waste disposal levy. The treatment chemistry inside it, which the plant paid to buy, is lost with it. The generator pays for the binder, the freight, the gate fee and the levy, and keeps the liability.
The treatment chemistry is recovered and credited back where it can be. The residual leaves as concentrate. Regen takes residuals as standing work: priced per kilogram, scheduled around the plant, cleared on a cycle that suits production. Every run closes with an independent laboratory report so the residual stops being a line on the generator’s liability register.
