THE USE OF WASTE FROM THE WOOD PROCESSING AND FOOD INDUSTRIES TO IMPROVE THE PROPERTIES OF WOOD COMPOSITES

New formulations for processing pine wood based on vegetable oil waste using nanoscale magnesium oxide have been studied. As a filler in the composition of impregnating compositions, coniferous wood flour was used in an amount from 1 to 3%, as well as magnesium oxide nanopowder in a dosage from 0.01 to 0.1%. Processing pine wood with compositions based on vegetable oil with additives of magnesium oxide allows to improve the hydrophobic properties of the wood surface, reduce its swelling, moisture and water absorption. The most optimal parameters were obtained from wood samples treated with a composition containing 1% wood flour, 0.01% magnesium oxide and 1% siccative.
