Qualitative analysis of reducing packaging consumption through reusable systems for takeaway containers

This thesis is a qualitative review of reusable takeaway systems and how they may decrease packaging consumption and so negative environmental effects.First, the thesis introduces plastic, the main material used for both disposable and reusable food packaging.Its benefits and disadvantages, as well as its economic implications are explained.The thesis finds plastic to be a complex set of materials and delves into further details on different types of plastic.The thesis also determines that plastic still has heavy environmental impacts and a high potential for environmental improvement, especially through recycling, and new technologies using alternative feedstocks.Thus, while plastic is a necessary and practical material, action is needed for improved lifecycle management.This has been recognised by governments who have taken legislative action, which is examined by this thesis with a focus on the EU.Because of plastic's examined features, this thesis establishes that it is also a practical material for reusable takeaway containers.Hence the thesis examines LCAs, which compare disposable with reusable plastic containers as well as other materials, aluminium, bagasse, and glass.Various LCAs indicate that PP is a sustainable choice for a reusable container system under certain conditions, if the container is reused at least 40 times.The use of local manufacturers, commercial dishwashers and short distribution paths are important factors, too.Overall, findings confirm that indeed a reusable plastic container system is preferable to disposable containers.
