The demand for biobased polymers is growing rapidly. However, due to production processes consisting of several batch processes, biopolymers such as polylactic acid (PLA) still have the potential for an increased commercially exploitation. In order to overcome these problems, twelve partners launched the InnoREX project in December 2013. This FP7 EU-project aims at the continuous, highly precise, metal-free polymerization of PLA using alternative energies for reactive extrusion. In this presentation the projects innovations regarding impact of microwave and ultrasound incorporation on the process opportunities and its influence on process performance and material characteristics will be show. The consortiums work to simulate the overall polymerisation kinetic, alternative energy input, and to model the drastically changing viscosity during polymerisation will be further presented. This comes together in a Ludovic® user module able to simulation polymerisations in a twin screw extruder under alternative energy input. By the date of this talk the project has ended 1 month ago, such this talk will cover all the InnoREX developments throughout the value chain, from findings regarding catalysts, process optimisation, according simulation to material performance from end-user point of view.
