Effects of intensive microbial metabolism on starch-filled polyethylene films in controlled compositing windows.

Abstract: Low density (LDPE) and high density (HDPE) polyethylene films filled with starch up to a maximum level of 20% by weight were tested for biodegradation under different environmental conditions. Composting windrows consisting of various putrescible waste and assembled for controlled biostabilization management under static conditions were used. The physical and chemical deterioration of the polyethylene-starch films exposed to a controlled composting environment were recorded and analyzed with respect to the dif… Show more

“…Moreover, both M w and M n decrease rapidly at the initial stage of the irradiation, and then the decrease becomes slow with the reaction proceeding. In polymer degradation where chain scission occurs at random, one always can see a rapid initial molecular weight decrease, which slows down as the process continues ( , ).
3 Weight loss of PS−TiO 2 and PS−(TiO 2 /CuPc) samples at different irradiation times.

“…Because the (natural resources)-based filler is biodegradable and conventional thermoplastic like polyolefin is nonbiodegradable, the combination of these two materials is classified as a partially biodegradable system. On exposure to the microbial activities, the starch-based materials are weakened as a result of degradation, thus leading to a partial breakdown process referred to as biofragmentation [1]. Production of partially or fully biodegradable materials has offered a possible solution to the polymer waste disposal problem associated with the petroleum-based plastics.…”
