Plastic bottles filled with sand used to build houses in Nigeria

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.

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.
