Assessing Benefits and Risks of Incorporating Plastic Waste in Construction Materials

Recently, efforts to recycle or downcycle plastics into building materials have accelerated, leading to incorporation of plastic waste into materials such as composite asphalt-plastic roads, plastic adhesives, and plastic-concrete. However, research suggests these practices may exacerbate environmental, health, and social problems, acting as “greenwashing” that distracts from real solutions. This mini review evaluates the impacts of using plastic waste in construction materials and calls for caution and further research before widespread adoption. Read the full review to explore the evidence and recommendations in detail.
