Performance Assessment of E-Waste Plastic as a Sustainable Natural Aggregate Substitute in Traditional Concrete: A Comprehensive Review

Globally, e-waste plastic recycling has emerged as a more popular and creative way to manage electronic waste, which is also being accepted since this resource is available in enormous amounts, comprises many kinds of hazardous components, and possesses a very low recycling rate. Growing urbanization, industrialization, and economic expansion are driving global concrete production, causing pollution and depleting natural resources. Using e-waste plastic as a natural aggregate presents a novel method for conserving resources and addressing the challenges of electronic waste, plastic, and concrete production. This article discusses different e-waste plastic types, techniques for producing e-plastic aggregates, and their application in traditional concrete. Additionally, this study examined the behavior of e-waste plastic aggregates, which affect various concrete characteristics. These include fresh properties such as workability, as well as hardened characteristics such as density (both fresh and dried), splitting tension strength, flexural strength, compressive strength, and durability aspects such as chloride attack and thermal resistance. Reusing electronic waste plastic as aggregates is also a new hope for protecting the environment and guaranteeing the secure disposal of the enormous amount of e-plastic waste generated. However, additional research is needed to address e-waste disposal challenges and its use in conventional concrete.
