Finnish footwear firm Rens has launched a sustainable running shoe made from coffee waste and recycled plastic bottles. While there are a number of products made from recycled plastic bottles, there are fewer that use coffee grounds. Yet coffee makes up around 13 per cent of Finland’s annual food refuse. Only fruit and veg are thrown in the bin more often. And this is important because, according to Rens, used coffee grounds emit as much methane as 10 million cars.

Rens’ first-generation of recycled trainers, dubbed ‘Originals’ contain around 300 grammes of coffee waste, equivalent to 21 cups. The spent grounds are mixed with recycled plastic pellets from used water bottles. The material is used to create what the company calls coffee polyester yarn, which is turned into the upper part of the shoe.
