Each year, 7 million tons of seashells are discarded by the seafood industry and aquaculture. Even though some of the seashells have been recycled and used as fertilisers, the majority of them are thrown into landfills or dumped by the seaside and piled up on beaches. This causes odour pollution and pollutes the surrounding area in the long run.
Yet, these shells are materials with high potential, which consist of over 90% calcium carbonate. The project ‘Sea Stone’ proposes the use of discarded seashells to create an environmentally and economically sustainable material as an alternative to contributing to the world’s rubbish problem. Moreover, it is expected to positively impact on three issues, such as: reducing waste disposal costs, preventing marine pollution and recycling waste, by creating value-added products with artistic, aesthetic and functional new uses.
The studio collects discarded seashells from seafood industries and then shells are then processed, ground and mixed with various natural ingredients.
