Abstract

Svake godine na tržište se stavlja velika količina električne i elektroničke opreme, a istovremeno se mala količina električnog i elektroničkog otpada pravilno prikuplja i reciklira. U EE-otpadu su sadržane velike količine opasnih tvari, ali i vrijednih sirovina. Nakon primarnog uklanjanja opasnih tvari, ovaj otpad se usitnjava i razdvaja. U ovom diplomskom radu su navedeni i opisani postupci usitnjavanja i razdvajanja EE-otpada. Detaljno je opisan proces recikliranja kućanskih uređaja. Optičko razvrstavanje je napredan postupak koji se koristi za razvrstavanje usitnjenog EE-otpada. Optički separator je uređaj visoke osjetljivosti koji može razvrstavati EE-otpad na temelju boje, oblika i transparentnosti. U radu su opisane njegove mogućnosti i prednosti te ograničenja i nedostaci.
U eksperimentalnom dijelu ovog diplomskog rada ispitane su mogućnosti optičkog separatora na uzorku usitnjenog EE-otpada te je napravljena usporedba s podatcima dobivenim postupkom ručne separacije.

Abstract (english)

Every year, a large amount of electrical and electronic equipment is placed on the market, while at the same time a small amount of electrical and electronic waste (WEEE) is properly collected and recycled. E-waste contains large quantities of hazardous substances, but also valuable raw materials. After the primary removal of hazardous substances, this waste is shredded and separated. In this master thesis the procedures of shredding and separation of e-waste are listed and described. The process of recycling household appliances is described in detail. Optical sorting is an advanced process used to sort shredded e-waste. An optical separator is a highly sensitive device that can sort e-waste based on color, shape, and transparency. In this thesis capabilities and advantages are described as well as its limitations and disadvantages.
In the experimental part of the master thesis the possibilities of the optical separator on the sample of crushed EE-waste were examined and a comparison was made with the data obtained by the manual separation process.
