In Nigeria, specifically in the town of Yelwa, the first house was built using recycled plastic bottles.
This construction maintains the characteristic rounded shape of the houses in the north of the country, but reusing a waste that would otherwise only be a polluting waste, making garbage a good construction material.
Influential people from the nation and reporters have come to the place to see and support this ecological cause, since this house has become a tourist attraction.
According to Yahaya Ahmed of the Association for the Development of Renewable Energy in Nigeria, a house like this can cost a third of a similar one built with bricks and concrete. The house is composed of a bedroom, living room, kitchen, toilet and bathroom and requires approximately 7,800 bottles for its construction.
You get solid walls, resistant to earthquakes, and even to shots, -according to indicate- and with good thermal insulation, which makes them perfect for a very hot area like this in the center of Africa.
The construction sequence would be first, a concrete base that ensures stability and firmness, the PET plastic bottles are filled with recycled materials from the construction, being sand or earth. The bottles are placed next to each other forming rows as if they were bricks, they are joined with mud.
Subsequently the interior wall of the house is also repelled with mud, leaving the lower part of the bottles outwards, which even gives a certain beauty to the construction. This constructive system is even more resistant than traditional systems.
In addition, the house has solar energy - they do not specify anything else - it has an eco-efficient fuel stove, a fertilization system through the reuse of urine, tanks for storage and purification of water, among other features. that practically turns it into a self-sufficient house.
A form of construction that is already used in Africa and Latin America, which is making a difference not only by reducing plastic waste, but also by lengthening the durability of the bottles to give shelter to the most destitute.
