• In this study, lignin was characterized through elemental analysis, Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) in order to understand the potential use for future value added applications, with a major focus on composite materials. Lignins exhibited a little high sulphur. Thermogravimetric curves of the lignin demonstrated good thermal stability. Ligin/PVC composites were prepared and the effect of lignin incorporation was investigated by means of mechanical properties. Lignin added to the composite was obtained by the dual-roll milling process. The composites were prepared by molding and assessed by means of tensile testing. The results showed that no more than 15w% of lignin did not reduce tensile strength and in its presence hardness property was improved.
