The team of scientists from the Center for Marine Debris Research at Hawaii Pacific University in Honolulu run a program called Nets-to-Roads.
Through this, the team of marine biologists collect and sort through ocean plastic waste made from a durable type of plastic called polyethylene, which is found in milk bottles, yoghurt pots and fishing nets.
Once collected and sorted the team then sent the waste to the US, where it was shredded and ground into tiny pieces.
From there it was returned back to Hawaii and taken to a pavement production facility, where it was mixed with other ingredients to make asphalt – the material used to make roads.
The hot mix was then loaded onto trucks and used to pave some test roads.
