hkpmfvfeyawc73ch3yzvolrhkm.jpg The CCA-treated timber waste is equivalent to about 175,000 10m-high pine trees going to waste annually. The treated timber is used in several industries, including residential construction, landscape gardening and horticulture. The New Zealand Timber Preservation Council, proprietors of the WOODmark® programme, a nationwide quality assurance programme for treated timber said that CCA-treated wood was a safe and environmentally friendly material. There have been several recent proposals on how best to counteract the problem and safely dispose of treated timber. Timaru District Council, working in conjunction with Waste Transformation Limited, currently operate a pyrolysis plant but it can only process 200 tons of timber waste per month.
