    Construction company, VolkerWessels, is using recycled plastic bottles to pave the roads. Lightweight and easily installed, the roads are built to last three times longer.

        Kenya should not ban plastics rather build roads from the waste

        There's 40+ years of plastic waste to make enough roads. Ban them now and keep the country clean.

        Just can't agree..Recycling is a whole big industry on its own. Plastic waste is a huge source of raw material for this industry.

        When you see the sections of pipelines and cables nicely cutting themselves into pieces and flying away, you know it's a swindle.

        I do wonder if this would work in hotter climates. But if it'll work anywhere at all that's less in the landfills. Awesome idea!
