The invention of plastic has been a double-edged sword for humanity. While the cheap, versatile material has made life convenient, it is virtually indestructible and takes centuries to decompose. Since avoiding plastic is impossible, companies worldwide are coming up with innovative ways to repurpose the millions of tons of polymer waste that end up in our landfills annually. Among the latest is California-based TechniSoil Industrial, which has devised an ingenious way to reuse plastic waste to repave roads.
Road resurfacing is an expensive undertaking that starts with using special equipment to extract and grind the topmost 3-to-6 inches of asphalt. Since the recycled material is not strong enough to use on its own, half of it is discarded and replaced with fresh hot asphalt. The combined product is mixed with bitumen — a sludge-like petroleum residue that acts as a binding agent — and relaid on the surface. Repaving a single lane mile requires 42 truckloads of new material and hauling out a similar amount of unusable waste.
