Containers must be empty. You don’t have to rinse each container but it will certainly help you to store them cleanly before returning them.
Lids should be removed from bottles as they are a different type of plastic to the bottle, and interfere with our machinery as well as the greater recycling process.
Please note that some container refund points are unable to identify the barcode on a crushed can or bottle, so these should be taken to a container refund point which accepts crushed or damaged containers, providing they can be recognized as being an eligible container. For safety reasons, glass bottles need to be whole and intact.
