Marks & Spencer has introduced a new scheme that encourages customers to bring their own reusable containers to M&S's Market Place food-to-go counters, whereby they receive a 25 pence discount off each meal for doing so. M&S already offers a 25p incentive for hot drinks served in reusable coffee cups since last year. The retailer hopes the discount will encourage a change in consumer behaviour and reduce the use of disposable items on the high street.

M&S also just launched a new, widely recyclable terracotta CPET tray to replace the hard-to-recycle black plastic used in its ready meals. The retailer pledged to completely remove all black plastic from its food division by the end of 2020.
