Abstract
U ovom radu pod otpadom se podrazumijeva plastični otpad (lampioni). Ako se otpadom ne gospodari kako treba ili ga se nekontrolirano odlaže, on će onečistiti okoliš. Mnoge vrste plastike nisu biorazgradive bez obzira na uvjete u okolišu, barem ne u značajnoj mjeri, dok se neke vrste razgrađuju, ali sporo, pod uvjetom da su izložene povoljnom djelovanju zraka, vode i svjetla. Lampioni nisu biorazgradivi jer ni metal, niti plastika, niti parafin od kojih se sastoji lampion nisu biorazgradivi. Uzorak u provedenim ispitivanjima se sastoji od lampiona koji su izdrobljeni, prosijani i atrirani. Krupnije klase ne odgovaraju jer su prevelike za atricijsku ćeliju, a kod sitnijih klasa postoji velika mogućnost gubitaka materijala tijekom daljnih ispitivanja. Nakon postignutog raščina drobljenjem i odvajanja parafina i plastike pliva-tone separacijom na zrnu plastike zaostaje tanak sloj parafina. Hipoteza ovog rada je uklanjanje tog sloja parafina atriranjem. Uspješnost atricije razmatra se preko smanjenja sadržaja parafina. U svim pokusima došlo je do smanjenja masenog udjela parafina u koncentratu nakon atricije što nam govori da je hipoteza ovoga rada potvrđena.
Abstract (english)
Under the term waste in this thesis, we assume plastic waste (lanterns). If waste is not properly managed or it is discarded it can pollute the environment. Regardless of environmental conditions a lot of plastic is not biodegradable, however, some types are degradable with favorable effects of air, water and light. Since metal, paraffin and plastic are not biodegradable, neither are lanterns. Used test sample is composed of crushed, sieved and attritioned lanterns. Coarse fractions are too big for atrittion cell so they don´t fit while smaller classes result in material loss during further testing. After liberation by crushing and separation of paraffin and plastic by sink and float process, a thin layer of paraffin remains on plastic grains. Attrition efficacy is considered through reduced content of paraffin. In all tests, decrease in mass portion of paraffin in concentrate after the attrition is determined, which tells us that the hypothesis of this thesis is accurate.
