<onlyinclude>In '''Biocomposite processing''' bio-based materials are processed to composite materials. Normally these material consist of a polymeric matrix that can be fossil- or bio-based and bio-based materials fixed in this like wood dust, natural fibres, straws, rice husks, nutshells and others. Best-known biocomposites are Wood-Plastic-Composites (WPC) or Natural-fibre reinforced materials.</onlyinclude> | <onlyinclude>In '''Biocomposite processing''' bio-based materials are processed to composite materials.

. | There are several types of biocomposites on the markets that normally have a fossil-based matrix with natural fibre reinforcement or wood filling. In principal also the matrix can be bio-based consisting of bio-based polymers like PLA, bio-PE, biogenic epoxis or PHAs. | ||

... | In the compounding process the matrix materials are melted and then mixed with fillers, plasticisers, additives and fibres to a homogenous formulate that can be given into a screw extruder. This produces an extrudate that will be cooled down in a water bath and then cutted into composite granules. The granules can be used to produce several types of products e.g. by injection moulding or other material processing technologies. | ||
