Three types of birch wood plywood by-products: plywood sanding dust (PSD), plywood sawdust (PSWD) and refined plywood scrap fibres (RPSF) and polypropylene composites exploitation properties (tensile, flexural modulus), microhardness water resistance and fluidity of composite melts, were evaluated. These investigations showed possibility of usage as excellent reinforcements for polypropylene presented by-products. For example tensile modulus increase up to 5 times, but flexural modulus till 2.3 times. Optimal content of PSD in polypropylene composites is 40 wt%, but in the cases of PSWD and RPSF 50 wt%.
