Different sizes of sawdust or veneer-like pieces of wood have been mixed together with nanocellulose. Additional adhesives or glue is not needed to bind materials together. The composite can be manufactured into boards or formed three-dimensional objects utilizing moulding technique. Material does not need to be hot pressed, during the drying period the material
The structure of the extremely lightweight wood-nanocellulose composites is dense compared for example typical MDF-boards used in furniture or construction industry. Haptic properties, such as surface temperature and texture, is similar as in wood-based products. Composite pieces can be drilled, sawed and sanded in the same way as wood.
Wood-nanocellulose composites can be utilized in furniture or construction industry when lightweight but stiff boards or three-dimensional shapes are needed.
