There are 14 specialist shops at the Retuna shopping mall in Eskilstuna, Sweden, but they all have one thing in common. Every item for sale in the shopping centre is second-hand. The clever thing about this mall is its location. It is right next to the city’s refuse and recycling centre. When people come to drop off mattresses and cardboard, they also pass by the mall’s basement to leave unwanted items that can be resold – or indeed items that can be ‘upcycled’, given a new lease of life as a different kind of object. Every shop is run as a money-making business, rather than a charity. The mall also hosts a college that offers a one-year certified course in upcycling, hoping to inspire a new generation of entrepreneurs who believe in sustainability. Presiding over the whole enterprise is Anna Bergstrom. Her mission is to make second-hand shopping a mainstream experience – even one that’s a little bit glamorous.
