In the hills of north-west Morocco, overlooking the river that gives the site its name, research at Oued Beht is bringing to light a previously unknown chapter of the region’s past. The discovery of a substantial built structure suggests that, during the second millennium BC, communities in north-west Africa were actively shaping their environment. They were also engaging in broader networks of interaction across the Mediterranean world.
Previous research by the Oued Beht Archaeological Project had already

Yet out of the 60 metals contained in old electronic devices like phones, screens or washing machines, only a few get recycled. That includes precious metals like gold or silver and some other metals like aluminium or copper.
