Paula Sarsama (right) and Managing Director Markku Vilkki of Conenor Oy are well up in the manufacturing methods of entirely recyclable wood-plastic composite materials. |
Lumber made of wood-plastic composite is already commonly used in the USA for outdoor porches and awnings. Other applications include durable cases for consumer goods and designer products. The proportion of wood fibre in the end product may vary from 20% to as much as 90%, depending on the manufacturing method.
High quality waste wood, side products of the wood processing industry and good recycled plastic can be used as raw materials for wood-plastic composites. The raw materials to be combined are thus inexpensive. There is a new unique technology which can even utilise fresh sawdust. Promising results have likewise been obtained from tests in which wood-plastic composite was manufactured from wood chips and shavings heat-treated by VTT and plastics.

Wood-plastic composites require plastic granules and wood chips or shavings. |
According to Markku Vilkki, managing director of the Finnish company Conenor Oy, the co-operation headed by VTT will enhance the credibility of the wood-plastic composite in the wood processing industry. The research findings so far are a good support for getting business activities off to a fast start in Finland. According to Mr. Vilkki the fact that the production of high-tech wood products can be started cost-effectively with the methods of the plastics industry and small initial investments will serve to increase demand.
