In Libya, municipal and agricultural wastes are increasing each year leading to disposal problems. The use of municipal and agricultural wastes, particularly the natural polymers as compost are well known and the making of new products is receiving greater attention by researchers. The aim of this work was to study the thermal properties of biodegradable films which prepared from the reaction of PVA with lignin at a mass ratio of 1:2, 2:2, 3:2, and 4:2 respectively. Prepared biodegradable films used in this study have been thermally characterized by thermogravimetry (TGA) and differential scanning calorimetry (DSC) techniques. The results showed that the polymer blends were moderately thermally stable and the prepared PVA-lignin blended film may be potentially suitable as an eco-friendly packing material.
