Public voting has opened for the Green Alley Award, Europe’s first startup prize for the circular economy. We scan the shortlist and reveal what trailblazing trash-busters made the cut

Using rubbish rather than raw materials to create new products is the cornerstone of circular economics. This approach twists the linear, planet-trashing take-make-waste linear model into a planet-friendly loop.

Recognising the trailblazing startups that are leading the way in circularity is the annual Green Alley Award. This year, organisers want the public to vote for their favourite from the shortlist below.

Circular economy
1. Chemicle

Using dairy waste to make recyclable plastic is broadly the aim at Chemicle, a UK startup that had the gouda idea of turning cheese whey into a bio-alternative to oil. It is then used in the production of plastic. chemicle.co.uk

2. Kleiderly

Globally, a reported 87 per cent of materials used in clothing end up in landfill or incinerators. Enter Kleiderly, which transforms textile waste into a sustainable plastic alternative for use in furniture and, fittingly, clothes hangers. kleiderly.com

4. Carbonauten
