Abstract
Razvojem industrije dolazi do stvaranja velikih količina otpada kojeg ponekad nije moguće sanirati, te velik dio otpada završi u prirodi, gdje predstavlja ekološki problem. Taj problem se može riješiti recikliranjem i pravilnim saniranjem otpada, te uporabom biorazgradljivih materijala. Biorazgradljivi materijali se mogu razgrađivati u okolišu primjenom različitih mikroorganizama, te imaju pozitivan utjecaj na okoliš. Neki od biorazgradljivih materijala su polimerni materijali, koji imaju široku primjenu te se koriste u mnogobrojnim sektorima, najviše u ambalažnoj industriji i poljoprivredi. U ovom istraživanju ispitana je biorazgradljivost polimera, odnosno termoplastičnog škroba (TPS), polilaktida (PLA), polihidroksialkanoata (PHA), polikaprolaktona (PCL), te njihovih mješavina. Uzorci su promatrani prije i poslije procesa biorazgradnje polarizacijskim mikroskopom, te je izračunata promjena mase tijekom 56 dana procesa biorazgradnje. Uzorci su također analizirani FTIR-ATR spektroskopijom. Dobiveni rezultati pokazuje da je tijekom 56 dana procesa došlo do biorazgradnje svih polimernih materijala i njihovih mješavina. Zbog svojih svojstava, neki polimeri su bolje razgradivi, poput TPS-a koji je bolje razgradiv od PLA.
Abstract (english)
With the development of industry, large amounts of waste are created, which sometimes cannot be remediated, and a large part of the waste ends up in nature, where it is an environmental problem. This problem can be solved by recycling and proper remediation of waste, and the use of biodegradable materials. Biodegradable materials can be degraded in the environment using various microorganisms and have a positive impact on the environment. Some of the biodegradable materials are polymeric materials, which have a wide range of applications and are used in many sectors, mostly in the packaging industry and agriculture. In this study, the biodegradability of polymers, i.e. thermoplastic starch (TPS), polylactide (PLA), polyhydroxyalkanoate (PHA), polycaprolactone (PCL), and their mixtures were examined. Samples were observed before and after the biodegradation process with a polarization microscope, and the change in mass was monitored during 56 days of the biodegradation process. Also, the samples were analyzed by FTIR-ATR spectroscopy. The results obtained show that during the 56 days of the process, biodegradation of all polymeric materials and their mixtures occurred. Due to their properties, some polymers are more degradable, such as TPS, which is better degradable than PLA.
