Why We Should Use Waste Plastic and Glass in Road Construction: A Sustainable Solution for Cleaner Cities and Stronger Roads Why Waste Plastic and Glass Should Be Used in Road Construction | Environmental Benefits Introduction Plastic and glass waste have become two of the biggest environmental challenges of the 21st century. Every year, millions of tons of plastic packaging, bottles, containers, and broken glass are discarded. Much of this waste ends up in landfills, rivers, forests, and oceans, where it can remain for decades—or even centuries—without decomposing. Instead of treating these materials as useless waste, many countries are transforming them into valuable resources. One of the most promising innovations is using recycled plastic and crushed glass in road construction. Roads built with recycled materials can reduce pollution, decrease landfill waste, conserve natural resources, lower construction costs in some cases, and support a circular economy. While recycled materials...
