Bottle house

Many of us would shudder if someone suggested that they build a house for us out of rubbish, but the bottle house definitely makes one reconsider all previous speculations about homes made from reclaimed materials.
The German company Eco-Tec initially explored this method of construction.

Considering the future of housing is quickly progressing towards the desire for sustainable housing, low-emission, low maintenance houses that respect our environment, this is surely an idea that has great potential, especially in Nigeria where plastic waste is a frequent sight on our expressways and gutters.

A house was recently constructed from recycled plastic bottles in Kaduna. The technique requires the voids within the building material to be filled with either mud,sand or clay, to provide insulation and also to give the finished wall strength and support. It is said that the "three- room structure" in Kaduna  "is so sturdy that it could stand for thousands of years.'' Since the bottles take several hundreds of years to biodegrade this might as well be very true.

Not only does this mean that the house uses up a material which would instead be left to fill up our landfills or even worse litter the public environment, but it also means that housing can be made even more affordable for all. This new completed house will put good use to the thousands of bottles collected in the Nigeria’s bottle recycling programme which was launched in December 2010.

To encourage this initiative "Andres Froesse, founder of Eco-Tec Soluciones Ambientales, was sent to Nigeria to train local masons in the bottle building technique”.
The Project Manager, Chris Vassilou, donated the land for the first bottle house building. "Features in the bottle house include solar powered with fuel-sufficient clean cookstove, urine filtration fertilization systems and water purification tanks, thereby, making it energy autonomous."..

"Advantages bottles have over bricks and other construction materials include:

Low cost;
Non-Brittle;
Absorbs abrupt shock loads;
Bio climatic;
Re-usable;
Less construction material;
Easy to build and;
Green Construction.

When you make a clay brick, the time and energy used right from mixing the clay to baking it in the kiln and taking into account the firewood used for that, you will see that the bottle brick is far more energy-efficient. The technology also reduces the carbon emission that happens during the baking of an ordinary brick.
The heat generation from cement factories can also be reduced as this technology uses only five percent cement. The foundation for the entire construction is obtained from building waste and so the mountains from which granite is blasted out can be saved too. PET Bottle can last as long as 300 years – longer than the cement used to bind the bottles together in the walls."
