Eco-bricks are empty plastic bottle filled with inorganic rubbish. Over the years I have helped to build benches, walls, a restaurant, school, a health centre (as seen in the photo) and inspired numerous other buildings.
An international group of problem solvers came together and formed the Global Ecobrick Alliance http://www.ecobricks.org/
The next step on from eco bricks is the machinery that turns plastic into a new product https://preciousplastic.com/en/
We must clean up the petroleum based plastic and instead of burning it transform it into something else.
