Povzetek
Močna porast proizvodnje različnih izdelkov na osnovi različnih plastičnih materialov povečuje tudi nastajanje plastičnih odpadkov, kar ustvarja nove izzive, saj se različni plastični materiali različno reciklirajo oz. zaključujejo svoj življenjski cikel. Kljub temu, da Slovenija že dosega cilj 55 % recikliranja plastične embalaže do leta 2030, pa za oceno vplivov plastike na okolje skozi njen celotni življenjski cikel v Sloveniji še ni bilo opravljene raziskave. Analiza materialnega toka plastike v Sloveniji zajema zadnje statistično leto, tj. 2021. Študija magistrske naloge predstavlja LCA analizo (Analizo življenjskega cikla (angl. Life Cycle Assessment) plastičnih tokov, ki obsegajo 8 vrst plastičnih polimerjev (LDPE, HDPE, PVC, PET, PUR, PP, PS in ostala plastika) ter vse faze življenjskega cikla z različnimi scenariji v končni fazi. Analiza je bila izvedena z uporabo programskega orodja Open LCA in ReCiPe 2016 metodo ocenjevanja vpliva življenjskega cikla. Glavni dejavniki, ki prispevajo k okoljskim obremenitvam, so bili identificirani skozi vse faze življenjskega cikla. Izkazalo se je, da ima največji vpliv na okolje pri vseh osmih proučevanih plastikah faza proizvodnje, vodilna pri vplivih na okolje je ostala plastika (ki je je tudi količinsko največ), sledi ji HD-PE. Najmanj okoljskih vplivov se pojavlja pri plastikah PVC in LDPE. Vseh 8 plastik pa dosega največje vplive na okolje v kategoriji globalnega segrevanja. Po primerjavi z različnima končnima scenarijema (100 % sežig in 100 % reciklaža) ugotovimo, da je najmanj sporen za okolje scenarij 100 % reciklaže, saj ima zaradi povratne zanke najmanjši vpliv na okolje.

Life cycle assessment of plastic flows in Slovenia from environmental impacts assessment |
Sekundarni povzetek: |
A strong increase in the production of various products based on different plastic materials is also increasing the creation of plastic waste, which creates new challenges as different plastic materials are recycled differently or they differently end their life cycle. Although Slovenia is already on the way to meet the target of 55% recycling of plastic packaging by 2030, no research has yet been carried out to assess the environmental impacts of plastics through their entire life circle in Slovenia. The analysis of the material flow of plastics in Slovenia covers the latest statistic year, 2021. The MA thesis study presents an LCA (Life Cycle Assessment) analysis of plastic flows, covering eight types of plastic polymers (LDPE, HDPE, PVC, PET, PUR, PP, PS and other plastics), as well as all the phases of life cycle with different scenarios in the final phase. The analysis was carried out with the Open LCA software tool and the ReCiPE 2016 method of estimating the impact of life cycle. The main factors that contribute to the environmental burdens have been identified throughout all the phases of life cycle. The results have revealed that, out of eight studied plastics, the production phase has the biggest impact on environment. The other plastics (which also have the highest quantity) took the leading role in the impact on environment and is followed by HD-PE. The PVC and LDPE plastics have the lowest impact on the environment; however, all eight plastics have the highest environmental impact in the category of global warming. After the comparison with different final scenarios (100 % incineration and 100 % recycling), it can be concluded that the 100% recycling scenario is least environmentally controversial, as it has the lowest impact on environment because of the feedback loop. |
