The jute wastes from the machine-made carpet-production factories were used as a model. The effects of several parameters such as enzyme concentration, pH and time on the recycling process were evaluated. The optimum enzyme concentration, reaction time and pH for the recycling of jute wastes were 1.5 %, 2 h and 8, respectively. The results showed that the enzymatic process using pulpzyme was an effective method to hydrolyse cellulosic chains, shorten cellulosic fibers such as jute and decrease its moisture regain (%). The products obtained from the enzymatic process using pulpzyme are suitable raw materials for paper-making processes due to their length range between 0 mm to 4 mmV članku je prikazana encimska obdelava odpadkov jute z uporabo pulpzima. Kot model so bili uporabljeni odpadki jute pri strojni izdelavi preprog. Ocenjen je bil učinek več parametrov, kot so koncentracija encima, pH in čas za postopek recikliranja. Optimalna koncentracija encima, čas reakcije in pH pri recikliranju odpadkov jute so bili 1,5 %, 2 h in 8. Rezultati so pokazali, da je encimski postopek z uporabo pulpzima učinkovita metoda za hidrolizo celuloznih verig, skrajšanje celuloznih vlaken jute in zmanjšanje njene ponovne navlaženosti. Dobljeni produkti iz encimskega postopka z uporabo pulpzima so zaradi njihove dolžine od 0 mm do 4 mm primerni za izdelavo papirjaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
