Used chewing gum can be transformed into skateboard wheels. Beaches, meanwhile, benefit from crushed used glass.
Broken surfboards left by the sea are less hip, however. Therefore, a Welsh designer has developed a surfboard that serves as a breeding ground for corals in its second life.
The skeleton is 3D-printed from biodegradable material, and filled with fungal spores and straw.
Within three weeks, the mix forms a network of roots and the material can be cured. With properties similar to polystyrene, the board can then be shaped.
Now the 23-year-old is experimenting with natural materials such as beeswax and linseed oil to make the board waterproof. Next step: the production line.
And if surfing’s not your thing, how about sailing?
