Dezeen Wire: discarded bottles sourced from hotels, restaurants, homes and foreign embassies are being filled with sand and used as bricks to create curved-walled houses in a Nigerian village - BBC
The bottles are bound together with mud resulting in durable walls that are sustainable, cost-effective and provide insulation from the sun's heat. The resulting buildings are also bullet-proof – a useful benefit in an area plagued by violence. An estate of 25 houses is currently being built with plans for a school to follow.
