20.500.12556/RUL-186155 Izdelava in možnosti uporabe peletov iz ovčje volne diplomsko delo Production and possibility of using sheep wool pellets B. Sc. thesis Nepredelana ovčja volna ima status organskega odpadka oziroma spada med živalske stranske proizvode, ki jih morajo odvažati pooblaščene institucije. V praksi pa se veliko ovčje volne nekontrolirano odvrže v naravo ali celo zažge. Zaradi vsebnosti keratina in lanolina, ki predstavljata odličen vir organskih hranil in lahko nadomeščata organska gnojila, ima ovčja volna velik potencial za uporabo v vrtnarstvu (poljedeljstvu, kmetijstvu). V raziskavi smo preučili postopek izdelave peletov iz ovčje volne in možnosti njihove uporabe. Surovi ovčji volni smo določili osnovne lastnosti (vlažnost, gostoto nasutja) in jo ustrezno pripravili za izdelavo peletov. Izdelali smo pelete iz fino mlete, grobo mlete volne ter mešanic mlete volne in bukove žagovine. Izdelanim peletom smo določili vlažnost, mehansko obstojnost, gostoto nasutja in gostoto pelet. Ugotovili smo, da je peletiranje uspešno v primeru, da imamo ustrezno pripravljeno (mleto) ovčjo volno in da s postopkom peletiranja zelo poenostavimo rokovanje, shranjevanje in uporabo ovčje volne. Raw sheep wool is classified as organic waste or as an animal by-product that must be collected and processed by authorized institutions. In practice, however, a significant amount of wool is illegally dumped in nature or even burned, which poses an environmental burden.Sheep wool contains keratin and lanolin, both rich sources of organic nutrients that can partially replace organic fertilizers. Due to these properties, wool is a promising raw material for use in gardening, agriculture, and crop production. In this study, we examined the process of producing pellets from sheep wool and their potential applications. We first determined the basic physical properties of the raw wool, such as moisture content and bulk density, and then prepared it appropriately for further processing. Pellets were produced from finely and coarsely ground wool, as well as from mixtures of ground wool and beech sawdust. The produced pellets were tested for moisture content, mechanical durability, bulk density, and pellet density.We found that pellet production is successful when the wool is properly prepared (ground). Pelletizing sheep wool significantly simplifies handling, storage, and application of this otherwise waste material, opening up new opportunities for its sustainable use in agriculture. ovčja volna živalski stranski proizvodi organski odpadki peletiranje peleti trajnostno kmetijstvo organska gnojila diplomska dela sheep wool animal by-products organic waste pelleting pellets sustainable agriculture organic fertilizers true false false J.
