摘要

As more plastic waste accumulates in the environment, particularly polyethylene terephthalate (PET) bottles, and as industrial wastes build up, it is clear that both traditional construction methods and the current methods of manufacturing are both environmentally unsustainable, require too many resources, and cost too much. This proposal will compare and evaluate the construction utilise recycled PET bottles filled with fly ash, to those of traditional construction methods, and provide an alternative solution for providing low-cost, sustainable housing. The overall goal is to develop and test the feasibility of an integrated building system using PET bottles, filled with fly ash, which provides for structural stability, thermal comfort, cost effectiveness, and sustainable environmental development. The process used in this project will include the testing of 30 PET bottle bricks compared to traditional bricks for compressive strength, statistical analyses to verify consistency of performance, thermal insulation testing to assess heat transfer and indoor comfort, and a complete cost comparison of both bottle-based construction and traditional construction. The research suggests that PET bottle bricks have an average compressive strength (MPa) greater than traditional brick (7.88 MPa), which is supported by a standard deviation of 1.35 MPa for the PET bottle bricks versus 0.93 MPa for the conventional bricks. Furthermore, based on the cost of production of waste materials combined with the opportunity to utilize the labour force in close proximity to the construction site, there is an opportunity to reduce costs related to construction by as much as 55% when using PET bottle bricks. Therefore, the results further support that using a combination of PET bottles and fly ash serves as a structurally sound, thermally efficient, and economically may be a viable alternative to traditional materials used in the construction of buildings.
