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.
