Milliways, the UK’s fastest-growing gum brand and pioneer of plastic-free chewing gum, is launching into a select number of M&S Foodhalls with two of its best-selling flavours – Peppermint and Spearmint. The move marks another major milestone for the brand, which has already saved over 150 million pieces of plastic globally from entering our bodies and the environment.

This UK expansion comes at a time of continued success for Milliways on a global scale, as it takes on the legacy brands that have dominated the category for decades. Already available in major UK retailers like Tesco, Sainsbury’s and Ocado, and following international launches in the USA and France, the company is rapidly growing its presence while staying true to its mission: to replace the 1 billion pieces of plastic gum chewed over the next 5 years with Milliways.

Growing scientific evidence has highlighted the potential harms of ingesting microplastics, specifically those used as an ingredient in most chewing gum brands. A 2025 study by Queens University found that plastic gum can leach up to 250,000 microplastic particles per piece. As the UK’s largest plastic-free gum brand, Milliways is offering customers trusted quality without compromise. Milliways gum is made from just 7 plant-based ingredients and remains the only gum brand in the UK to be certified biodegradable and plastic-free.
