Abstract

Polimerni materijali nalaze se u gotovo u svim aspektima svakodnevnoga života. Polimeri se koriste za proizvodnju jednokratnih proizvoda poput ambalaže za hranu i piće, ali i predmeta dugog životnog vijeka kao što su, primjerice, PVC prozori. Poli(vinil-klorid) jedan je od najraširenijih polimernih materijala. Dobra mješljivost s omekšavalima i drugim dodacima, laka preradljivost kao i niska cijena omogućuju njegovu široku primjenu. Sve to dovodi do akumulacije velikih količina polimernog otpada što rezultira negativnim posljedicama za okoliš. Zbog rastućih troškova i sve veće brige za okoliš, odlaganje otpada na odlagališta postaje nepoželjno. Jedno od rješenja ovog problema je recikliranje PVC-a čime se smanjuje iscrpljivanje prirodnih resursa i potrošnja energije što dovodi do poboljšane ekološke učinkovitosti. U ovom su radu opisani načini zbrinjavanja PVC otpada, od nastajanja preko prikupljanja, razdvajanja, usitnjavanja i čišćenja do, u konačnici, samog procesa recikliranja.

Abstract (english)

Polymer materials are present in almost every aspect of our everyday life. Polymers are used to manufacture single-use disposable products like food and beverage containers, as well as long-life products, e.g. PVC windows. Poly(vinyl-chloride) is one of the most commonly used polymers. Good miscibility with plasticizers and other additives, good processability, as well as low cost, make it widely applicable. As a result, large amounts of polymer waste have been accumulated, resulting in negative environmental impact. Due to rising costs and increasing concern for the environment, landfilling is becoming no longer acceptable. One of the solutions to this problem is to recycle PVC waste, which reduces the use of natural resources and energy consumption, leading to a significant reduction in environmental impact of PVC. This paper describes available methods for the treatment and management of PVC waste, including collection, sorting by type, grinding, washing and, finally, the recycling processes.
