Abstract:V magistrskem delu obravnavamo vzpostavitev metodologije za vrednotenje odpadnih materialov, primernih za proces kemijskega recikliranja. Namen naloge je razviti sistematični nabor komplementarnih analitskih pristopov, s katerimi lahko zanesljivo ocenimo kakovost vhodnih odpadnih frakcij ter njihovo primernost za nadaljnjo predelavo s procesi kemijskega recikliranja. V raziskavi analiziramo frakcijo slabše kvalitete iz realnih odpadnih tokov, pridobljenih iz zbiralnice odpadkov, pri čemer kritično ovrednotimo tudi sezonski vpliv na njihovo sestavo. Uporabimo nabor različnih analiznih tehnik za vrednotenje fizikalno kemijskih lastnosti, kot so sestava, polimerni delež, bruto toploto izgorevanja, vsebnost vlage in nečistoč. Posebno pozornost namenjamo tudi primerjavi vzorcev iz zimskega in poletnega obdobja. Negativni rezultati raziskave dodatno potrjujejo, da je ustrezno vrednotenje in predpriprava materialov ključnega pomena za njihovo primernost za kemijsko recikliranje. Pokazali smo, da bi vrednotenje ustrezno predpripravljenih vzorcev (ustrezno sortiranje, pranje in sušenje), tudi iz enake vhodne frakcije, lahko vodilo do bistveno boljših rezultatov. Na podlagi rezultatov ugotavljamo, da je za ustrezno vrednotenje odpadnih materialov nujna uporaba več analitskih analiznih metod, za celovito karakterizacijo primernosti odpadne frakcije za proces kemijskega recikliranja. Razvita metodologija predstavlja osnovo za izboljšano selekcijo vhodnih tokov in optimizacijo kemijskega recikliranja.

Title:Establishing a methodology to evaluate waste materials suitable for chemical recycling process
Abstract:In this master's thesis, we establish a methodology to evaluate waste materials suitable for chemical recycling processes. The aim of the study is to develop a systematic set of complementary analytical approaches that enable reliable assessment of the quality of incoming waste fractions and their suitability for further processing by chemical recycling. We analyse a lower-quality fraction from real waste streams obtained from a waste collection facility, and critically evaluatethe seasonal influence on its composition. We employ a range of analytical techniques to assess physicochemical properties such as composition, polymer content, gross calorific value, moisture content and impurities. Particular attention is also given to the comparison of samples from winter and summer periods. The negative results of the study confirm that proper evaluation and pre-treatment of materials are crucial for their suitability for chemical recycling. We demonstrate that evaluating appropriately pre-treated samples (including proper sorting, washing and drying), even from the same input fraction, can lead to significantly improved results. Based on the results, we conclude that the use of multiple analytical methods in essential for the proper evaluation of waste materials and for a comprehensive characterization of the suitability of waste fractions for chemical recycling processes. The developed methodology provides a foundation for improved selection of input streams and optimization of chemical recycling.
