Metso development manager Mika Viljanmaa receives Marcus Wallenberg Prize 2012



FALUN,Sweden , Oct. 2, 2012 (Press Release) - 

During a ceremony at the Grand Hôtel in Stockholm on 1 October, the Swedish King, His Majesty Carl XVI Gustaf awarded the Marcus Wallenberg Prize 2012 to Mr. Mika Viljanmaa for his ground-breaking development of metal belt calendering technology resulting in better paper print surfaces with less fibre materials and higher production efficiency.

Calendering is done to improve the paper surface and thus print quality. Compared to conventional calendering, the metal belt calendering technology enables manufacturing of paper and board with better surface smoothness at a desired level of stiffness and bulk, but using 3-10% less fibre raw material. In addition, it consumes less energy and yields higher production efficiency than other calendering concepts. It is particularly suitable for low cost fibres such as recycled fibres and thus enables development of new cost-competitive paper and board products.
