The current global annual production of plastic materials is around 365 million tons. Their commercial success is related to a combination of different properties: strength, lightweight, flexibility and stability. However, there are many concerns related to the production and use of conventional plastic, originating from its excessive carbon footprint and its resistance to biodegradation. The increasing awareness about plastic pollution and its environmental impact are highlighting the need to develop sustainable materials to replace oil-based and non-biodegradable plastics. In this setting, biodegradable polyesters play a crucial role. Among all the biopolyesters, polylactid acid (PLA) has attracted attention as a biodegradable and bio-based material, reaching industrial-scale production.
