Denmark has a thriving second-hand economy, in part because people generally don't look down on second-hand goods here.
The Danes are practical people – why should something be thrown out when it can be used again? And their passion for sustainability means it's cool to reuse something that already exists instead of manufacturing something new.
There is a network of "genbrug" (recycling) stations all over all over the country, where people can leave stuff they don't want and other people can take it for free.
And there's a thriving market for second-hand furniture in the classic Danish design style.
