This study involved modelling to measure the greenhouse gas (GHG) emissions from reusable takeaway packaging compared to single-use equivalents. The results indicate that, for most types of takeaway packaging used in Europe, reuse through a safe, efficient system for collection, washing, inspection, and redistribution has potential to yield greater environmental benefits than recycling or discarding single-use containers. The study also highlights key aspects to optimise in designing and operating reuse systems.
