Abstract: In this project we try to overcome the problem associated with plastic waste. In India huge amount of plastics are used for various purposes such as for making of water bottle, soda bottles & bag etc. which are not disposable. Because of these various problems occurs so we use waste plastic bottles for making of bricks by the various ways which are discussed below. After studying the problem we developed the effective way to overcome this problem. Bottle brick are light in weight and withstand high amount of load or pressure. Eco-bricks, polyethylene terephthalate (PET) bottles filled with mixed inorganic waste, have become a low cost construction material and a valid recycling method to reduce waste disposal in regions where industrial recycling is not yet available. Because Eco-bricks are filled with mixed recovered materials, potential recycling of its constituents is difficult at the end of its life.
