Název v původním jazyce

Biodegradation of Modified Polyurethane Foams

Popis výsledku v původním jazyce

Increased production of non-degradable polymer waste by modern industrial society is accompanied by necessity to solve problems with negative effects to environment. In agreement with recent trends to avoid the accumulation of environmental pollution newmodified polyurethane (PUR) foams were synthesized. Biopolymer components (acetyl-, hydroxyethyl- and carboxymethyl cellulose, acetylated starch, glutein) were used as modifying agents. In this work biodegradability of modified PUR foams was tested using bacterial single strain (Arthrobacter globiformis), mixed bacterial culture (Thermophillus sp.) and selected moulds strains (Fusarium solani, Alternaria alternata). In a complex comparative study standard biodegradability tests in laboratory conditions, in model composting conditions and also in different natural environments were used. In both bacterial systems, PUR biodegradation mechanism probably includes two additional effects: the abiotic decomposition followed by consequent util
