Sounds a little like an art project right? Maybe , but it`s actually much much more than that. D.A.R.E stands for Development Association for Renewable Energy, and they came up with the idea. Plastic bottles are pretty much the slowest biodegradable thing you will ever throw in your garbage can. So if they last so much why not build something with them? That`s what D.A.R.E thought I guess. The bottles are filled with earth or sand(preferably sand) , joined together at the neck by strings and cemented together with mud. This creates and incredibly sturdy , stable and lasting structure. The first house built this way is in Nigeria, where it solves another two big problems : the lack of housing, and the millions of plastic bottles laying around in rivers, on the streets etc. To make things even better, the project is designed to be self sustainable and will use solar panels, water filtration and a whole range of other eco sustainable toys.
