Department of Roads in Bhutan has teamed up with an entrepreneur and a recycling plant to use plastic waste in road mix.
Inspired by road paving technique used in some Indian cities, Ritesh Gurung, a plastic waste entrepreneur, approached his country’s roads department to use a similar technique in Bhutan. Under the Green Road project, plastic bottles and other plastic waste are processed in a recycling plant before the material is added to bitumen. The road paving technique uses 10-15% of recycled plastic, and may use up all the plastic waste generated in this small Himalayan kingdom in the long run.

The plastic road project is expected to reduce road construction and repair costs, in addition to reducing plastic waste in landfills by 30-40%.
