Recycling Plastic Waste into Eco-Friendly Concrete: A State of the Art Review

The world plastic waste crisis and the tremendous environmental impacts of concrete production using traditional methods require waste management and building practices to be innovative marriages. This review critically examines the recovery of plastic waste in concrete, concentrating on its twin potential to help stem plastic contamination and build the construction industry lower in carbon emissions. The method utilizes many different forms of waste plastics, including Polyethylene Terephthalate (PET) and High-Density Polyethylene (HDPE), to produce a concrete mixture that brings great environmental benefits: It can keep plastic out of landfills and our oceans, and it reduces the greenhouse gases released during cement production. The review examines advances in the development of plastic-modified concrete: These improvements include enhanced mechanical properties such as increased durability, thermal insulation, and lower material density. It also examines environmental trade-offs including potential long-term effects and problems in recycling plastic-enhanced concrete. In addition, the paper identifies technical hurdles such as maintaining material strength and workability; it concludes with regulatory obstacles to the large-scale adoption of plastic-enhanced concrete. The paper uses a detailed analysis of case studies and actual practices to examine the practical feasibility of this new material in a variety of construction contexts. It ends with strategic recommendations for future research and policy development, stressing the need to establish regulations and standard frameworks to encourage the use of plastic-enhanced concrete. Ultimately, this review advocates for the larger acceptance of plastic-laden concrete as one piece in the puzzle of sustainable construction: one way to tackle a spiraling global plastic waste crisis that also meets broader environmental goals.
