Bio-based polymer composites are widely used materials in many sectors of economy in Europe. Nowadays, thanks to the “green thinking”, these composites are on great interest to scientists and industry representatives. Main idea of biomass fiber usage in polymer composites is based on reduction of primary polymer application as well as integrated management of wood processing residues (wood chips, saw dust etc.). Hitherto some commercially viable examples of wood fiber as reinforcement material for polymer composites that are present on the market are produced from raw wood material from sustainably managed forests. Another biomass material that has attracted interest is grain husks. Grain husks is unavoidable by-product of grain milling. It is a “valuable” material with high cellulose content, yet there are no examples on viable industrial application of this material for now, except of incineration for energy generation. Due to a compilation of the scientific literature it has been found that husks fiber effect on composite material could be as good as wood fiber. Blending new composites on polypropylene base can reduce main disadvantages of husk fibers such as water sorption, swelling, form instability etc. Main interest from the part of industry could be raw husks at minimal costs. Raw husks have impurities and other admixtures such as grains, leafs, seeds, stems, sand, traces of pesticides and so on. Main idea of this work is to compare different types of grain husk preparation methods to ensure manufacturing of economically attractive polymer composites.
