Circular economy: six trash-busting startups that are reimagining rubbish


Europe’s first start-up award for circular economy has revealed its 2021 shortlist of finalists. From carbon-negative building materials to plastic made from old clothes, nominees offer novel solutions to pressing problems.

Until recently, the concept of circular economy was a marginal concern. In the context of a looming ecological crisis, progressive thinkers realized that the planet’s destructive linear model was not fit for purpose and advocated a new approach, one that used waste, rather than raw materials, to manufacture new products.

The idea has slowly seeped into mainstream discourse, with politicians in the EU and the UK introduce legislation designed to extend the life cycle of products and make them easier to repair. Multinationals like Ikea is also embracing the concept of a circular economy. There is a long way to go, of course, but it is a start.

The Green Alley Award He was a champion of the circular economy long before it became fashionable. Launched in 2014, it recognizes little-known startups that are leading the charge to develop products and services that eliminate waste.

Despite the pandemic, this year’s competition was packed with entries. With the help of the general public, including Positive News readers, who voted for their favorites online, six finalists were selected. The startup with the most votes was automatically included among the finalists; the remaining five were selected by a committee of experts on circular economy.
