British house turns old duvets and oyster shells into building materials

A house in Brighton has become a testing ground for building materials made from waste, including discarded oyster shells and old duvets.

Researchers collected the shells from a local restaurant, heated them and mixed them with crushed shells to create experimental tiles. The tiles were used to protect insulation made from reused bedding and duvets.

The project explored how locally available waste could be reused within the construction process. The resulting building prototype was also exhibited internationally.
