Abstract:

The aim ofthe investigation was the biodegradation of low-density polyethylene (LDPE) film modified with Bionolle®. The samples in the form of compositefilms were prepared by homogenization and extrusion. The biodegradation process was performed in the laboratory scale or under environmental conditions.The examined films were placed into different media and incubated in the presence of fungi Aspergillus niger, PenidUium funiculosum and mixed fungi inoculum.Any changes in the various properties of the films after biodegradation weremonitored by weight loss, optical and scanning electron microscopy and FTIRspectroscopy. The results of the study have proved that fungal growth on thepolymer samples containing low amount of polyester depends on the presenceof nutrients in media. Sucrose inhibited polymer disintegration more stronglythan nutrient broth. FTIR analysis revealed that filamentous fungi biodegradednot only polyester, but also polyethylene. On the contrary, LDPE incubated insoil did not exhibit any chemical changes. This highly hydrophobic polymer wasmore susceptible to biodegradation only in the presence of Bionolle®
