Abstract

Razvoj industrije, ubrzani ritam života i porast populacije dovode do stvaranja velikih količina otpada koji se najvećim dijelom sastoji od nerazgradivih materijala. Veliku količinu otpada nije moguće u kratkom roku pravilno sanirati te velik dio završava u prirodi gdje predstavlja ekološki i zdravstveni rizik. Osim recikliranja materijala i pravilnog saniranja otpada kao rješenje se nameću biorazgradivi materijali. Sam proces biorazgradnje ovisi o karakteristikama materijala, vrsti i broju prisutnih mikroorganizama te o uvjetima prisutnim u okolišu. Sintetski polimeri često su povezani s naftnom industrijom te se zbog ograničenosti naftnih zaliha, kao i zbog cijene nafte, znanstvenici i investitori okreću materijalima čije sirovine potječu iz drugih izvora, poželjno iz prirode. Sintetski biorazgradivi polimeri svojom strukturom oponašaju karakteristike prirodnih, a često se proizvode iz prirodnih sirovina koje su obnovljive, široko dostupne i jeftine. Upotreba biorazgradivih polimera najviše je zastupljena u ambalažnim proizvodima, farmaciji i medicini te agrokulturi.

Abstract (english)

Industrial development, fast-paced lifestyle and growth of world's population results in accumulation of waste, which is mainly composed of non-biodegradable materials. Most of that waste can not be properly managed in short period of time, and a lot of it ends up in the nature presenting ecological and health risk. Besides material recycling and proper waste management, another solution is using biodegradable materials. Biodegradability depends on material properties, number and species of microbes and conditions in the environment. Production of many synthetic polymers is connected to the oil industry which has limited reserves and the prices are getting higher, so scientist and investors are turning to raw materials from other sources, preferably from nature. In their structure, synthetic biodegradable polymers mimic natural ones, and they are often produced from natural raw materials which are reusable, accessible and affordable. Biodegradable materials are mostly used in packaging, pharmacy, medicine and agriculture.
