Abstract

Zbrinjavanje, recikliranje i ponovna uporaba otpada i otpadnih materijala zadobilo je veliku pozornost u posljednjih tridesetak godina, područje je koje napreduje velikom brzinom, te se nove tehnologije za sve aspekte gospodarenja otpadom razvijaju svakodnevno. U ovom radu istražuje se metoda spektroskopije laserom pobuđene plazme. To je relativno nova metoda koja brzo i učinkovito može dati rezultate i identificirati kemijski sastav otpada, a za nju nisu potrebni posebni laboratorijski uvjeti. Ovakva metoda može pospješiti metode razvrstavanja otpada što smanjuje troškove reciklaže materijala. Opisani su procesi identifikacije najučestalijih vrsta plastike, te identifikacija mješavina polimernog elektroničkog otpada.

Abstract (english)

Disposal, recycling and reuse of waste and waste materials has gained a lot of attention in the last thirty years, it is an area that is advancing rapidly, and new technologies for all aspects of waste management are being developed on a daily basis. This paper investigates the method of laser-induced breakdown spectroscopy, a relatively new method that can quickly and efficiently give results and identify the chemical composition of waste, and does not require special conditions. This method can improve waste sorting methods which reduces material recycling costs. The processes of identification of the most common types of plastics are described, as well as the identification of mixtures of polymer electronic waste.
