Abstract

In a first aspect, the present invention relates to a lignin based composite material containing degraded lignin obtained by reductive hydrogenation. The lignin based composite material is characterized in containing degraded lignin having a substantially reduced amount of ²-O-4 linkages. Further, the present invention relates to a method for producing said lignin based composite material according to the present invention comprising reductive hydrogenation of lignin in order to provide degraded lignin and mixing the same with protein and filler. Further, the present invention relates to a method for producing an article composed of the lignin based composite material according to the present invention obtainable by drying the material at a suitable temperature. Finally, the present invention relates to a molded article or semi-finished product composed of the lignin based composite material according to the present invention and the use of the lignin based composite material for various purposes including wood based material composed of the lignin based composite material according to the present invention.
