Recycled wallets

Car windscreens are lined with something called PVB (polyvinyl butyral) which stops the glass shattering into the passenger cabin in a crash. The material makes recycling the glass tricky, but it turns out that if you scrape it off, PVB can form a durable, biodegradable material that can be processed into something resembling leather. Wallet company Ekster has taken 600 windscreens and turned them into 240,000 wallets. Each wallet has a push lever at the base that cascades your cards out of the top, and you can pick up a tracker card that pings your phone with the last place you left your wallet.
