Thermal properties of polylactide / recycled lignin and cellulose filler biocomposites

Abstract

Bio-based polymer composites were prepared using poly-L-lactide (PLLA) as a matrix and three different types of natural fillers. Waste paper from regular office paper, cellulose from Tetra Pak® recycling industry and lignin waste from paper manufacturing industry were chosen as fillers. Density, crystallinity and melting/crystallization behavior of PLLA biocomposites loaded with different filler contents (20, 30, 40 wt.%) were compared and discussed.
