Non-degradable plastic bags are a major contributor to marine and soil pollution. They represent significant percentage of the generated solid waste can last for hundreds years in environment. The aim present study was find alternatives conventional non-degradable by obtaining biodegradable compostable starting from simple materials like starch, poly(lactic acid) (PLA), glycerol. Increasing strength hardness polymer achieved adding mineral (talcum). preliminary studies indicated that two compositions suitable advanced testing produce initial granular material. These were tested determination melt flow index (MFI), Fourier Transform Infrared Spectroscopy (FTIR), polymers response heating (thermogravimetric analysis, TGA differential scanning calorimetry, DSC). biodegradability evaluated burial types soil. obtained results compared with same set experiments performed on polyethylene bags. After three months soil, only synthesized this show signs accentuated degradation while still intact. surface morphology explored electron microscopy (SEM). thermoplastic material meets requirements European standard EN13432/2002 regarding packaging.
