A project in Nigeria is using plastic bottles to build houses. The plastic bottle helps to lower the cost of building and by clearing empty bottles, it helps the environment too. The bottles are picked up off the streets and collected from rubbish dumps.
The Plastic bottles are packed solid with soil and laid on top of each other then bound with mud and string. The developers claim the buildings can withstand earthquakes and bullets.
The project also creates job opportunities for those that are unemployed. A house made of plastic bottles costs a third of a normal house. This an idea for anyone looking to build a house in Africa cheaply.
