In the middle of the Sahara desert on the western border of Algeria, refugee camps hosting tens of thousands of people rely completely on humanitarian aid: Water, food, and other basic supplies come in on trucks. Trash, on the other hand, doesn’t really leave; until recently, all the waste from the camps was dumped nearby in the desert into an ever-growing pile of plastic. But at a new recycling center at one of the camps, refugees are now turning that plastic trash into furniture and other products that they can use. Precious Plastic, an organization with a DIY recycling system developed by a Dutch designer who wanted to make recycling more accessible, helped set up the center after the United Nations refugee agency, UNHCR, put out a call for solutions to help with the waste challenge at the camps.
