20.500.12556/DKUM-95019 Uporaba pametne embalaže za živila in njen vpliv na okolje diplomsko delo visokošolskega strokovnega študijskega programa I. stopnje The use of smart food packaging and its impact on the environment Diplomska naloga obravnava problematiko zavržene hrane, ki predstavlja pomemben izziv sodobne družbe. Posebej problematično je sadje, ki spada med najpogosteje zavržene skupine živil, pri čemer imajo banane pomemben delež. Kljub njihovi priljubljenosti na svetovni ravni so zaradi občutljivosti na hitro zorenje in propadanje pogosto zavržene, kar povzroča izgubo virov ter energije, vložene v pridelavo, transport in skladiščenje. Diplomsko delo preučuje vpliv različnih vrst embalaže na podaljšanje obstojnosti banan in okoljske vplive njihove dobavne verige. S programom OpenLCA smo izvedli analizo življenjskega cikla, pri čemer smo spremljali vplive od pridelave banan do njihove uporabe pri potrošniku. V raziskavo so bile vključene tri vrste embalaže za banane: vrečka iz polietilena nizke gostote, biorazgradljiva vrečka in kartonska škatla. Koncentracije ogljikovega dioksida in kisika smo spremljali s senzorji, dodatno pa smo testirali tudi aktivno embalažo z absorberji kisika in etilena. Analiza življenjskega cikla je pokazala, da največji okoljski vpliv izhaja iz transporta zaradi dolgih razdalj v dobavni verigi banan, pomemben delež pa predstavlja tudi poraba električne energije za hlajenje v skladiščih. Vpliv embalažnih materialov je bil razmeroma majhen. Rezultati eksperimentalnega dela kažejo, da aktivna embalaža z absorberji upočasni zorenje in s tem podaljša obstojnost banan. Najbolj učinkovita je bila kombinacija absorberjev kisika in etilena pri polietilenskih vrečkah, medtem ko se je pri biorazgradljivih vrečkah kot ustreznejši izkazal absorber kisika The thesis addresses the issue of food waste, a significant challenge for modern society. Fruit is particularly problematic, as it belongs to the most frequently discarded groups of food, with bananas accounting for a significant share. Despite their global popularity, bananas are often thrown away due to their sensitivity to rapid ripening and decay, which results in the loss of resources and energy invested in their cultivation, transport, and storage. The thesis examines the impact of various packaging types on extending the shelf life of bananas and the environmental implications of their supply chain. Using the OpenLCA software, a life cycle assessment was conducted, monitoring the impacts from banana cultivation to their use by consumers. The research included three types of packaging for bananas: a low-density polyethylene (LDPE) bag, a biodegradable bag, and a cardboard box. Concentrations of carbon dioxide and oxygen were monitored with sensors, and active packaging with oxygen and ethylene absorbers was also tested. The life cycle assessment showed that the largest environmental impact originates from transport due to the long distances in the banana supply chain, while electricity consumption for refrigeration in storage facilities also represents a significant share. The impact of packaging materials was relatively small. The results of the experimental part indicate that active packaging with absorbers slows down ripening and thus extends the shelf life of bananas. The most effective solution proved to be the combination of oxygen and ethylene absorbers in polyethylene bags, while in biodegradable bags, the oxygen absorber alone proved to be more suitable.
