Abstract
U Republici Hrvatskoj godišnje nastaje oko 1000 t otpadne vune nakon striže ovaca koja se ovisno o pasmini, obavlja jednom ili dvaput godišnje. Otpadna vuna najčešće se nepropisno zbrinjava ili odlaže u okoliš pri čemu dolazi do onečišćenja zraka, vode i tla. Poradi navedenog, u ovom radu je ispitan potencijal oporabe otpadne vune kao prirodnog adsorbensa za onečišćenja plavim dizelom u rijekama i morima za dvije pasmine ovaca. Rezultati ispitivanja adsorpcijskog kapaciteta ovčje vune za plavi dizel pokazali su da 1 g otpadne ovčje vune apsorbira u prosjeku 5 g plavog dizela, stoga ovčja vuna predstavlja važan prirodan adsorbens za učinkovitu i pravovremenu sanaciju onečišćenja vodenog okoliša uzrokovanog izlijevanjem nafte. Iako prema hijerarhiji gospodarenja otpadom energetska oporaba zauzima predzadnje mjesto u redu prvenstva, rezultati ispitivanja kvalitete otpadne ovčje vune nakon adsorpcije plavog dizela prema normi za kruta oporabljena goriva HR EN ISO 21640:2021 pokazuju da otpadna ovčja vuna nakon adsorpcije onečišćenja u vodenom okolišu može biti visoko vrijedan zamjenski energent. Energetskom oporabom otpada u cementnoj industriji ne dolazi do opterećenja sastavnica okoliša budući je to tehnološki proces bez ostatka - sav pepeo nakon energetske oporabe ugrađuje se u klinker. Također, ne dolazi do nekontroliranih emisija u zrak s obzirom da cementna industrija ima instaliranu tehnologiju koja iste održava u propisanim zakonskim okvirima.
Abstract (english)
In Croatia, around 1000 tons of waste wool are produced annually from sheep shearing, typically done once or twice a year depending on the breed. This waste wool is often improperly disposed of, leading to environmental pollution of air, water, and soil. This study explores the potential of using waste wool as a natural adsorbent for blue diesel pollution in rivers and seas, focusing on two sheep breeds. The results of this research show that 1 gram of waste wool can adsorb an average of 5 grams of diesel, which indicates its effectiveness as a natural adsorbent for mitigating oil spill pollution in aquatic environments. Although energy recovery is ranked low in the waste management hierarchy, quality tests of waste wool post-adsorption of blue diesel, as per the HR EN ISO 21640:2021 standard for solid recovered fuels, show that such wool can be a highly valuable alternative fuel. Energy recovery in the cement industry is environmentally friendly since the process is residue-free and all ash is incorporated into a clinker. Additionally, advanced technology which is applied in the cement industry ensures that emissions remain within legal limits, which prevents uncontrolled air pollution. Thus, waste wool not only aids in pollution control, but also offers a sustainable option for energy recovery.
