Wood Engineering Technology
WET has developed and holds the exclusive intellectual property for an engineered, glue laminated, wooden building material trade marked as Optimised Engineered Lumber - OEL™
The WET Story
In 2003 the three company founders developed a process for converting the large majority of NZ logs into OEL™ to add value to NZ’s forests and the Building supply chain through to a finished buildings.
The first full scale 7,000sq metre fully automated Industry 4.0 plant will be in full production in October 2024.
The OEL™ Product
OEL™ can use trees as young as 13 years and any grade of logs over a metre long.
OEL™ is strong, straight and dimensionally stable. Competition from other engineered wood products (EWP) is constrained by economic return and log grade availability.
OEL™ is utilizable in up to 8 storeys buildings. A direct substitute for high carbon emitting steel and concrete in mid-rise buildings. OEL™ is 80% lighter than a concrete and steel building with simpler and cheaper foundation design and construction.
The WET Process
Every log that comes into the plant is analysed and processed with the precision control of 13,000 computerised, autonomous decision points. Robotic sawing, then drying, testing and glue laminating to a calculated recipe into 6meter long GL12 graded EWP is done without human intervention. Optimal strength is obtained by the positioning of the strips in a specific sequence or “recipe” to optimise the stiffness. Every piece of timber produced by WET is stress tested to breaking strength before it leaves the plant. 90% of the equipment has been developed by WET and is their own patented intellectual property.
The whole production process takes twelve hours to turn raw logs into saleable lumber.
The market for OEL™
WET is the only technology which is commercially viable to scale up to meet the rapidly increasing demand for this type of high strength wood product. In New Zealand a housing supply shortage of approximately 70,000 dwellings will be met by medium density buildings and off-site manufacturing which WET products are well suited for.
OEL™ is a net absorber of carbon. The plants are fully energy self-sufficient, utilising waste, mainly sawdust from the production process.
WET’s vision for the future
Standardised OEL™ production plants, using the latest computerised and robotic technology, will be replicated around NZ. Plants can be located clos to the forests, minimising the need for expensive road haulage and bringing employment to regions.
WET’s immediate plan is to scale operations up to 10 plants in New Zealand by 2030 providing a projected 327,500 cubic metres per annum of OEL™
