π Scallop Shells Turned Into Strong Fishermen Helmets
A Japanese village in Hokkaido faced a huge waste problem with 40,000 tonnes of scallop shells annually. Koushi Chemical Industry in Sarufutsu found a way to repurpose this seafood waste. They crushed the shells into powder, blended it with plastic to create 'Shellstic.' This material was then used to make 'Shellmet' helmets, which are 33% stronger than standard plastic ones. The process also cuts down on carbon dioxide emissions, though full recycling isn't there yet. π
