Plastic is one of the most disposable materials in the modern world. plastic bottles are increasingly becoming a menace to the environment due to the chemicals used in the manufacture, improper use and disposal. waste plastic bottles are used for filling up landfills which polluted to soil, choking water bodies and causing serious environmental consequences. on the other hand, world human population continually increase so needed more houses and land for construction. now a day, it is difficult to make own house for poor people of the world by using costly construction material. can we use waste bottles for construction? yes, it is difficult to think of a bottle as a brick. but a mud-filled bottle is as strong as a brick and whatever you can do with a brick; you can do with a bottle, too. when the bottles are filled with soil or sand they work as bricks and form a framework for walls or pillars. plaster made of clay or a cement mixture fills the space between all bottles while a roof made of wood or corrugated metal completes the house. as only regional products are used the houses are cheap and can be afforded even by poor families. our project intends to investigate the application of waste plastic bottles as one of the urban wastage in buildings construction and that how it can lead to sustainable development. in this project, we try to different patten’s for construction of plastic bottle masonry and compare various factors like as compressive strength, durability and construction cost with normal brick masonry.
