Are polyethylene films with prooxidants biodegradable ?

Popis výsledku v původním jazyce

Biodegradability of high density polyethylene film (HDPE) and low density polyethylene film (LDPE) both additivated with balanced content of antioxidants and prooxidants was studied with defined microbial strains in mineral medium. The abiotic pretreatment consisting of thermooxidation and photooxidation corresponding to about three years of outdoor weathering resulted to complete loss of mechanical properties and disintegration into small fragments. Metabolic activity was monitored by measuring ATP content. Simultaneously the cultures were controlled also by optical microscopy and FTIR spectroscopy. Results from long study are presented. This new polymer material represents perspective solution to the problem of visual pollution by plastic litter butits ultimate degradability must be further evaluated.
