Abstract
Električni i elektronički otpad je najbrže rastuća kategorija otpada uz komunalni otpad, te stoga postoji potreba za njegovim učinkovitim zbrinjavanjem. Kabeli i žice su neophodni dijelovi elektroničke opreme. Recikliranje otpadnih električnih kablova usredotočuje se na ponovno dobivanje vrijednih metala – bakra, s obzirom da je prosječni minimalni sadržaj bakra u rudi 0,5 % dok je prosječni sadržaj bakra u otpadnim kablovima 30 %. Prikazanim i opisanim metodama obrade otpadnih kablova, mehaničkom i pirolitičkom obradom, dobivene su frakcije bakra iste kvalitete i čistoće (99,0 %). U procesu mehaničke obrade nastaju otpadni polimeri (oko 60 %) čije zbrinjavanje predstavlja problem za okoliš i veliki trošak u procesu oporabe. Pirolitički proces (vakuumska piroliza) ne stvara novonastali otpad već se dobiva pirolitičko ulje (oko 33 %) koje ima primjenu kao energent i predstavlja mogući prihod.
Abstract (english)
Electric and electronic waste is the fastest growing category of waste, along municipal waste, hence there is a need for its efficient disposal. Cables and wires are essential parts of electronic equipment. The main focus of recycling waste electrical cable is on renewing valuable metals - copper, considering that the average minimum share of copper in ore is 0.5 %, while the average share of copper in waste cables is 30 %. By implementing the described and discussed methods of processing waste cable, both mechanical and pyrolytic processing, have resulted in copper fractions of the same quality and purity (99.0 %). In the process of mechanical treatment, waste polymers are formed (approx. 60 %) whose disposal represents a problem for the environment and a major expense in the recovery process. The pyrolytic process (vacuum pyrolysis) does not generate new waste, but instead generates pyrolytic oil (approx. 33 %) which is used as an energy source and represents a potential revenue.
