Types of packaging waste from secondary sources (supermarkets) – The situation in the UK

Packaging waste is a contributing factor to the large quantity of waste that is sent to landfill in the UK. This research focuses on waste from the secondary packaging sector in the UK. In particular, supermarkets were investigated as they supply a large section of consumers with their grocery and other requirements and generate high quantities of packaging waste due to the high turnover within the store. In general, supermarkets use either metal cages or wooden pallets to transport products from depot to store. Investigation shows that packaging waste produced when using the wooden pallets is greater than for metal cages but the use of wooden pallets allows for greater versatility when in the store. The type of transit packaging used depends on what the products are initially packaged in and how the supermarket supply chain works. All cardboard and high-grade plastic is recycled but, depending on the facilities at the stores, the low-grade plastic can be recycled as well. This paper details types of packaging used within the supermarket secondary packaging sector and how waste can be reduced. To reduce the amount of packaging waste produced by the supermarkets, the products will have to be wrapped differently by the producers so that less packaging is needed in transit.
