<p>The article outlines the problem of accumulation of short-fibered waste generated during chipboard sawing. Intense impact on the material determines a high level of technological availability of wood waste. The research objective is to create magnesia composite materials for various purposes based on chipboard processing waste. Moulding sands containing caustic magnesite, fly ash, aluminosilicate ash microsphere, wood waste and magnesium chloride solution have been studied. Change in the ratio of moulding sands’ components provided production of finely dispersed composite material, and granules of cylindrical and spherical shapes. Composite materials of coarse-pored structure have been developed on the basis of magnesia granules and hybrid magnesia-ash binder. Combination of layers of finely dispersed and coarse-pored materials has been proposed to form composites of variotropic structure with density 780–840 kg/m<sup>3</sup> and strength 9.7–11.9 MPa. Combined structures’ stability is achieved due to the high adhesive ability of magnesia binders and genetic commonality of various layers.</p>
