Municipal Solid Waste Thermal Analysis—Pyrolysis Kinetics and Decomposition Reactions

In this study, 12 organic waste materials were subjected to TG/DTG thermogravimetric analysis and DSC calorimetric analysis. These analyses provided basic information about thermochemical transformations degradation rates during pyrolysis. Organic divided into six groups as follows: paper, cardboard, textiles, plastics, hygiene waste, biodegradable waste. For each group, two selected be studied. Research (i) paper (receipts, cotton wool); (ii) cardboard (cardboard, egg carton); (iii) textiles (cotton, leather); (iv) plastics (polyethylene (PET), polyurethane (PU)); (v) (diapers, leno); (vi) (chicken meat, potato peel). Waste chosen represent the most abundant that can found in municipal solid stream. Based on TG results, kinetic parameters according Coats–Redfern method determined. The pyrolysis activation energy was highest for cotton, 134.5 kJ × (mol?K)?1, lowest leather, 25.2 (mol?K)?1. showed a number of occurred material. transformation, normalized required or released determined, then summarized present balance. study balance negative only three materials—PET (?220.1 J g?1), leather (?66.8 chicken meat (?130.3 g?1)—whereas positive value peelings (367.8 g?1). obtained results may applied modelling mass
