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.
包装废弃物是导致英国大量垃圾被运往垃圾填埋场的一个因素。这项研究聚焦于英国二级包装行业产生的废弃物。特别是对超市进行了调查，因为超市为大量消费者提供食品杂货和其他所需物品，且由于店内周转量高而产生大量包装废弃物。一般来说，超市使用金属笼或木托盘将产品从仓库运输到商店。调查显示，使用木托盘时产生的包装废弃物比使用金属笼时多，但在商店中使用木托盘具有更大的通用性。所使用的运输包装类型取决于产品最初的包装形式以及超市供应链的运作方式。所有纸板和高档塑料都可回收利用，但根据商店的设施情况，低档塑料也可以回收。本文详细介绍了超市二级包装行业内使用的包装类型以及如何减少废弃物。为了减少超市产生的包装废弃物量，生产商将不得不对产品采用不同的包装方式，以便在运输过程中减少所需的包装。
