Description
Plastic plays an important role in almost all areas of our life, starting from packaging, medicine to automotive and maritime industry. To increase value and environmental impact of bio-economy to society, the use of sustainable polymer materials based on various raw materials a widely developed. Poly(lactic acid) (PLA) is a biodegradable and bio-based aliphatic polyester derived from renewable sources such as corn sugar, potato, and sugar cane. PLA has played a central role in replacing fossil-based polymers for certain applications. While lignin is a sustainable, biodegradable and relatively cheap waste material for the bio-based composite materials preparation due to their availability from various waste streams, especially involving paper production industry.
Thereto, a bio-based polymer composites have been prepared using poly-L-lactide (PLLA) as a matrix and lignin particles of paper manufacturing waste has been chosen as a filler.
In this study we report an inventory analysis of these sustainable materials. Thermal, tensile and processing properties of the obtained sustainable composite materials have been described. Morphological characteristics have been investigated by optical and electron microscopy.
