Bottle uppers, seaweed soles
A Mexican inventor, Jorge Castro Ramos, has created a way of using the sargassum seaweed that washes up on beaches each year in the hundreds of tonnes: sports shoe soles.
Having already developed a way to create clothing-grade fibre from plastic bottles (hurrah from us!) and using that process to make water-resistant uppers, Jorge has now found a way to use the seaweed to make the soles. The amount of metals in the weed means that it cannot be ingested so this is a great way to use up what would otherwise lie rotting in the sun. Once the shoes have reached the end of their life they can be returned to the company which makes them and can be recycled all over again. How about that for sustainabillity! We think they look rather cool too.
