Ecobricks can be used to produce modular items. Old plastic bottles are filled with plastic waste. This waste is pounded together with a stick.
The bottles are then bundled together to form a square block. Ecobricks can be used to make a variety of products, ranging from chairs to walls and you can even build entire houses with them.
After an earthquake hit Lombok, a aid organization came up with the idea and Ecobricks is now spread across Indonesia.
This way plastic is recycled usefully and it can always be reused to build something else with it.
