Building with bottles / Construyendo con botellas

Long time ago, I joined a group in facebook called "Construyendo con botellas" (in English "building with bottles"). 


They are a group of different professionals and students from different fields that have run up a NPO in Uruguay. This NPO is developing a program to build houses with bottles for the people that really need it. Dra. Ingrid Vaca Diez (Bolivia) is the mother of this incredible idea that resolves two problems with one action: Cheaper costs to build houses for needy people and resolve an environmental problem.


The blog is in Spanish, but at least you can see the pictures and the projects they are developing. Maybe some of you can develop something similar in your countries!!


Bravo for this idea and the encourage to make it real.
