Scientists Are Turning Ocean Trash Into Roads – and It’s Actually Working

Researchers in Hawaii are testing asphalt made from discarded fishing nets and other plastic waste on real roads.

The goal is to create durable pavement while checking that recycled plastics do not shed harmful microplastics.

Early results are promising, suggesting a practical local use for hard-to-recycle marine and household debris.

The project involves Hawaiʻi Pacific University, the state transportation department, and road tests on Oahu.
