Analysis of combustible fractions in mixed municipal waste and packaging and calculation of energy value

Magistrsko delo obravnava analizo gorljivih frakcij v mešanih komunalnih odpadkih in embalaži ter preračun energijske vrednosti. Predstavljeni in opisani so načini termične obdelave odpadkov ter metode priprave alternativnih goriv in klasifikacija. Magistrsko delo opisuje metodo analize kaloričnih vrednosti. Izpostavljeni sta dve termični analizi, s katerima so obravnavane posamezne frakcije, termogravimetrična analiza in diferenčna dinamična kalorimetrija. Predstavljeni so rezultati obeh termičnih analiz, s katerimi opazujemo odzive posameznih vrst plastike pri različnih temperaturah ter spremembo fizikalnih in kemijskih lastnosti. Problematiko, ki smo jo analizirali v magistrskem delu, predstavlja predvsem plastika, ki se lahko reciklira, vendar je zaradi različnih dejavnikov ni mogoče več ponovno uporabiti. Predstavljeni in opisani so tudi rezultati strukturne analize zbiranja odpadkov v gospodinjstvih in na podlagi analize preračuna energijska vrednost zabojnika mešanih komunalnih odpadkov ter smiselnost ponovne uporabe odpadkov.The master\u27s thesis deals with the analysis of combustible fractions in mixed municipal waste and packaging and the calculation of energy value. Methods of thermal treatment of waste and methods of preparation of alternative fuels and classifications are presented and described. Two thermal analyzes are presented, which deal with individual fractions, thermogravimetric analysis and differential dynamic calorimetry. The results of both thermal analyzes are presented, with which we observe the responses of individual types of plastics at different temperatures, as well as the change in physical and chemical properties. The problem that we analyzed in the master\u27s thesis is mainly recyclable plastic, which can no longer be reused due to various factors. The results of the structural analysis of household waste collection are also presented and described and based on the analysis the energy value of the container of mixed municipal waste and the reasonableness of waste reuse are recalculated
