Tanalised® E is commercially available chrome and arsenic-free timber preservative based on the active ingredients copper and tebucozanole and is suitable for residential and commercial application, above and below ground. ** (see note under Warranties below)
Product Description:
Tanalised® E Pressure Treated Wood is arange of termite resistant structural timber and decorative timberproducts suitable for both indoor and outdoor applications. The productis treated with Tanalised® E wood preservative,which contains Copper and Azole Biocides to provide protection againstfungal decay, soft rots, insect borers and termites both in and out ofground contact. The wood preservative concentrate is manufactured inUnited Kingdom but the actual treatment is done is South Africa.
Tanalised® Eis an environmentally advanced timber preservative that incorporates a unique copper azole based wood protection system. Tanalised® Econformsto the latest United States EPA, European Union and Australiandirectives regarding suitable wood products for residential and closehuman contact use. Copper azole based preservatives are in wide usearound the world including many countries in Europe, the United Statesand more specifically Japan, New Zealand, Australia in the Asia Pacificregion.

|
|
Indicative Costs |
Please contact the manufacturer for more details. The cost for theproduct is more than CCA treated wood. The chemical treatment cost ofCCA treated wood for H2/H3 is approximately R300 per m³ compared toapproximately R500 per m³ for Tanalised® E treatedwood. These costs are dependent on price changes from time to time, anddifferential between the two types of treatment should drop over timewith increased volumes.The preservative is imported from the UK. |

ECOSPECIFIER LIFE-CYCLE ASSESSMENT
INTEGRATED DESIGN AND POLICY ISSUES
Thistreated timber avoids the issues induced by an arsenic based treatment.Arsenic pentoxide is a known toxic chemical. The general population isexposed to naturally occurring trace amounts in the environment, infoods and in drinking water. In relation to treated timber products, arsenic could be absorbed via the skin, inhaled when wood is burnt or ingested via small fragments of wood.
Firstly, for products that are manufactured after treatment and re-drying, thereare potentially less problems with disposing of the dressing wastecompared to CCA (Copper Chrome Arsenic). Also, for certain products inexport destinations such as decking in Australia, a non-arseniccontaining preservative is required under their regulations and anumber of specialist New Zealand producers are responding to thisopportunity. Finally there are cases where certain local public worksprojects have specified expensive imported hardwoods rather than CCAtreated pine, and the non-arsenic based treatment is a potentiallyacceptable alternative solution.
Preservatives treatment enhancesthe durability and utility of wood products by protecting them frombiological agents such as decay and termites thus prolonging the useful life of the timber, reducing environmental impacts and reducing the need to add a timber treatment after the timber in place.
Preservatives treatment enhances the durability and utility of wood products by protecting them from biological agents such as decay and termites thus prolonging the useful life of the timber, reducing environmental impacts and reducing the need to add a timber treatment after the timber in place.
This preservative treatment avoids the issues induced by CCA (Copper Chrome Arsenic) based compounds. Arsenic is a known toxic chemical. The general population is exposed to naturallyoccurring trace amounts in the environment, in foods and in drinkingwater. In relation to treated timber products, arsenic could beabsorbed via the skin, inhaled when wood is burnt or ingested via small fragments of wood.
For products that are manufactured after treatment and re-drying, there are potentially less problems with disposing of the dressing waste compared to CCA (Copper Chrome Arsenic) as chrome is a heavy metal, bioccumulative and toxic in even very small quantities. Also, for certain products in export destinations such as decking in Australia, a non-arsenic containing preservative is required under their regulations and a number of specialist New Zealand producers are responding to this opportunity. Finally there are cases where certain local public works projects have specified expensive imported hardwoods rather than CCA treated pine, and the non-arsenic based treatment is a potentially acceptable alternative solution.
HUMAN HEALTH
Health
Inthe context of this product, boric acid is considered non-toxic tohumans. However, European Commission classified boric acid as reprotoxiccategory 2, based on high concentration animal studies although thisstudy has caused considerable controversy.
Alkanolamine(2-aminoethanol) is a Volatile Organic Compound (VOC) under the EUdefinition. However it is used to dissolve copper carbonate/copper andis effectively consumed as it forms copper amine complexes in solution.In the context of this product, this component is not dangerous because of the small quantity.
In the manufacture of the woodpreservative, emission of components are controlled to minimum levelsthrough closed vessels with extraction linked to scrubber systems.

ECOLOGICAL QUALITY
Terrestrial
Emissions –Manufacture of non ferrous metal (copper) potentially emit NationalPollutant Inventory (NPI) listed substances (source: Non-ferrous MetalManufacture v1.1, 2001 and Structural and Metal Product). These impacts are minimised due to the regulatory and management practises in place inthe forests and plantations timber is sourced from.
Physical –Extractionof copper results in the removal and stockpiling of topsoil, andremoving overburden and inter-burden, resulting in modified soilprofiles, topography and drainage.
Aquatic
Emissions– The extraction of copper, bauxite and brass and the production ofaluminium and other metals has localised emissions to aquaticenvironments around production facilities.
Physical – Not known
Atmosphere
Greenhouse (GHG)– Theability of timber products to store absorbed carbon and emit minimalgreenhouse gases during production is a major consideration whencomparing timber to alternative materials. The carbon sequestered duringthe life cycle of timbers has the potential to offset the emissionsfrom the use of the preservative and result in a carbon neutral productor even a carbon sink.
