Recycling PLA
Overview
The bioplastic recycling module will look at closing the loop on bioplastics before they even begin to gain traction as a viable and more desirable plastic. We will be looking at degrading and synthesising polylactic acid (PLA) and poly-3-hydroxybutyrate (P3HB) using a fully biological system. The byproducts from the breakdown of our bioplastics will be separated then purified in order to allow them to be reused in industry
