The move is part of the company’s commitment to eliminating single-use plastic from its restaurants by 2025.
The five-month trial will be conducted at five restaurants in Ipswich and Newmarket, where customers can use reusable cups or burger containers instead of single-use plastic by making a £1 ($1.26) deposit.
To return a cup or container, customers can download the Loop mobile app, scan the barcode on the packaging and keep it in a Loop bin placed outside selected Burger King restaurants.
Customers will be given a refund of their deposit when returning cups or containers.
The five restaurants taking part in the trial are Ipswich Copdock Interchange, Ipswich Europark, Ipswich Westend Road, Ipswich Anglia Retail Park and Newmarket Fordham Road.
Customers can choose from ten Burger King products that are being served in the Loop reusable packaging, including a range of burgers, sides and drinks.
Burger King UK commercial planning and environmental, social and governance (ESG) director Nicola Pierce said: “We’re delighted to unveil a trial range of re-usable and returnable packaging for our restaurants.
“The launch of the new packaging from Burger King UK will include the first ever reusable and returnable ‘clamshell’ for burgers and sides in the UK.
“We’re excited to see how the trial performs over the next five months and help us reach our goal of eliminating single-use plastic within our restaurants by 2025.”
In 2020, Burger King and Loop announced a partnership to pilot reusable packaging at select restaurants in the US and Japan.
The pilot was initially carried out in New York City, Portland and Tokyo before being expanded to other cities over the following months.
