Bottle schools are schools built using plastic bottles stuffed with inorganic trash. Bottle schools are built using tried and tested post and beam construction. The foundations, columns and beams are made from concrete reinforced with rebar. The difference with traditional construction is that instead of cinder-blocks, the walls are made using “eco-bricks”. Bottle schools are much cheaper to build than traditional schools, they clean up the environment, teach lessons about environmental sustainability, and involve the entire community in their construction, resulting in a sense of pride and ownership.
