Noise barrier highway

To which topic does your idea refer?

Material Innovation

Describe your idea! How does it work to reduce / replace plastic? How will you involve others?

My idea is to use plastic waste to build noise barriers on highways. Plastic can be pressed and then melted towards the best shape. This way a lot of plastic waste can be transformed in a senseful way. I know it is not a solution yet to avoid plastic. But at least it re-uses single use plastic for a new long lasting product.
