Wood Manufacturing – a high-tech sunrise industry
Wood is beautiful, practical and strong, and it has more uses than people realize. In addition, it has such good environmental properties that using more wood instead of other materials would lower atmospheric carbon dioxide concentrations. 
A beautiful air control tower in Skellefteå, in the north of Sweden.We are not talking about a magic new material, but about ordinary wood, albeit subjected to high-tech processes in which its functional, aesthetic and environmental
properties are improved in order to produce higher-value products.
Nowadays wood research is conducted at most universities of techno-logy, often in close cooperation with the timber industry and wood research institutes such as SP Trätek. VINNOVA has identified wood manufacturing as a fast-growing industry and contributes research funding to it. Two sectors that are considered to have growth potential are the interior industry and wood-based construction.
Laminated wood (glulam) was the first processed wood material. Nowadays it is often used for structural beams in many different types of buildings. Another processed product on the market is called solidwood. It consists of cross-glued laminated timber that can be used for beams and other load-bearing structures. The technology ensures a strong, dimensionally stable and very light material. Solidwood can have a free span of up to 12 metres, but is only a quarter the weight of concrete.
Martinsons, a company in the village of Bygdsiljum in northern Sweden, has conducted intensive research in order to develop the new products glulam and solidwood.
– We have laid a good foundation for a successful business with excellent export opportunities, says Lars Martinson, the managing director.
– The new products are important, but at the moment we are concentrating
on developing effective and efficient system solutions. So we are designing standard modules that can be used in flexible applications. Building a wooden house should not be any more difficult than building one with Lego, says Lars Martinson. Martinson is very keen on the idea of building large apartment blocks of wood. A long-term research project has been started to produce finished modules with all the installations made at the factory. The buildings could then easily be assembled on the building-site. Five six-storey apartment blocks of wood with a total of 96 apartments have just been completed in Sundsvall, a seaside town in the north of Sweden. All those involved in the project were pleasantly surprised by the result.

– We were worried that noise might be a problem in these buildings, says Lars Martinson. But our newly developed patented sound-absorption system works better than we expected.
