ABSTRACT: This article presents a study focusing on a detailed analysis of the properties of a by-product from the production of cement-bonded particle boards, specifically cuttings. The volume of cuttings increases with the growth of production every year and these cuttings are not used further. Such cuttings represent landfill waste. Considering the composition of these cuttings, their re-use in the further production of particle board appears to be the most suitable option. Therefore, cuttings were subjected to adjustment of composition, size-reduction and separation of grain of defined size. Subsequently, all properties relevant to their possible re-use in production of particle boards were established. Thermic and caloric methods were predominantly used to define the contents of wood matter in relation to the cement matrix. Graininess, mineralogical composition and efficiency indexes, etc. were also studied

KEYWORDS: Cement-bonded particle board, by-product, waste, alternative raw material, cuttings, grinding, analysis, thermal, calorimetric methods, mineralogy
