The Wood Processing Centre at 9 Mile is also undergoing an expansion to cope with the future increase in output from the two sawmills in the Cloudy Bay Forest Management Area (FMA). Employment in the Wood Processing Centre is currently 120 people.
Processing of timber is done using two modern Michael Weinig Cutting and a Docking line with further processing done on two Michael Weinig Moulding lines and an additional cutting line will be installed in early 2011. The company also produces laminated beams and a range of custom furniture to order.
Cloudy Bay Sustainable Forestry Ltd is the first timber company in PNG, and the only timber company in the National Capital District to install and commission an Alkaline Copper Quaternary (ACQ) pressure treatment plant. The one treatment plant can pressure treat up to 20m³ per day in a single shift to Hazard Class H4 to H6 using CCA and a second larger treatment plant can pressure treat up to 50m³ per day to Hazard Class H1 to H3 using ACQ.
Our Kiln drying consists of four Solar Heated drying chambers and three steam heated drying chambers designed to provide and control the environmental conditions of heat, humidity, and air circulation necessary for the proper drying of wood. We can dry most species to any specified moisture content between 3 and 19 percent in a reasonably short time without appreciable losses caused by drying defects. Our current installed kiln drying facility has a capacity of 450m³.
Cloudy Bay Sustainable Forestry Wood Processing Facts:
- Our timbers are treated using an industry approved full cell vacuum / pressure impregnation process. The preservative used, Alkaline Copper Quarternary (ACQ), is a copper based formulation registered with the APVMA (Australian Pesticides and Veterinary Medicines Authority).
- ACQ is an internationally accepted timber preservative which is environmentally friendly as it does not contain Arsenic and Chromium.
- This timber treatment is in accordance with the PNG Standard for preservation of sawn and round timber and meets the QLD TUMA – 1994 (Timber Utilization and Marketing Act) penetration and loading requirements for Hazard Level Three (3) material.
Classification of service conditions and hazard levels:
|Hazard Class||Hazard Type Description/Service conditions|
|H1||Borer & termites Inside, above ground. Completely protected from weather & wetting, well ventilated|
|H2||Borer, termites and/or moderate decay Inside, clear of ground, completely or partially protected from weather & wetting|
|H3||Decay & insects Clear of ground, exposed to weather and/or subject to periodic wetting or condensation|
|H4||Severe decay, borer & termites Ground contact subject to severe wetting & leaching|
|H5||High decay and/or termites Ground contact or continuously damp situation|
|H6||Marine borer Permanently or semi-permanently in contact with sea water|
The Wood Process:
- Air Drying – Raw material from the Cloudy Bay Forest Management Area is placed in the drying yard for up to three months to reduce the moisture content below the fibre saturation point of 30%.
- Dimension Cutting – The slabs are sawn into standard cross sectional sizes on our state-of-the-art automated Michael Weinig Rip Line. Cloudy Bay Sustainable Forestry was the first timber company to install a Raimann KR450M Profi Rip Line in PNG and Australia.
- Docking & grading – Timbers are graded on marking stations and docked to length using a state-of-the-art Dimter Opti Cut Docking Line.
- Kiln drying – Cloudy Bay Sustainable Forestry kiln dries its most valuable timbers prior to processing them into products such as flooring, furniture, etc.
- Moulding Line – Cloudy Bay Sustainable Forestry invested in a new Moulding Line comprising of a Hydromat 2000 with automatic infeed and outfeed decks to improve its product quality on flooring, decking and other moulded products.
