Impregnation is a common method of protecting wood from external influences. This study proposes the use spent engine oil as an impregnating composition for modifying birch to make it resistant biological degradation and water. The indicators water resistance dimensional stability such wetting contact angle, thermogravimetric analysis, Fourier transform infrared spectroscopy (FTIR), biodegradation tests have been determined. It has found that treatment with significantly increases (56.8%...

Abstract The “hot-cold baths” impregnation of birch wood samples by a number oils (original engine oil, waste motor, spent transmission, corn and sunflower oils) were studied in order to choose base for impregnating composition. Specimens flour from coniferous hardwood species, oak, pine bark used as fillers compositions. Physical-chemical characteristics (absorbed amount impregnated compound, water absorption, swelling tangential radial directions, wetting angle) treated with compositions...

Pine sawdust, 0.5–1 mm in size, was made carbonized. The resulting biochar activated. This activated KOH confirmed to be a better methylene blue dye sorbent than the original charcoal. conclusion about possibility of using study results processing timber industry waste into carbon sorbents for water treatment systems and ensuring environmental safety production sites.
