Tanalised Timber

Tanalised Wood prior to treatment

An award winning, highly innovative and unique service has been developed by CSG to treat and process tanalised timber which until recently had inadequate disposal options.

Orginating from a wide range of sources such as cooling towers to garden sheds this waste stream has posed a problem for the industry due to the preservative (chromated copper arsenate) which bonds to the wood and is difficult to remove.

The developed process extracts hazardous components (copper, chrome and arsenic) leaving the wood clean and non-hazardous.

This innovative process ensures:

  • Diversion of waste from landfill
  • No incineration and therefore no risk of harmful emissions
  • Wood becomes classified as non-hazardous
  • Hazardous residues (Cu, Cr, As) insolubilised to meet WAC
