Each day more than 3 million plastic bottles were thrown away in the country, which has a population of about 160 million people.
Then the answer came – make houses out of the plastic bottles.
The containers are filled with sand, have their caps placed back on and are tied together with a network of strings before mud and cement bond them together.
Each bottle weighs about three kilograms when it is filled and the project officials say they are stronger than concrete blocks.
And the 58-square metre two-bedroom bungalow has the advantage of being fire proof, bullet proof and earthquake-resistant.
An estimated 14,000 bottles were used to create the house from huge piles of empty plastic bottles from embassies, hotels and restaurants.
