“Sea Stone”
Each year over 7 million tons of seashells are thrown away by the seafood industry into landfills. Shells are not biodegradable and have a very high disposal cost which harms the environment.
Newtab-22 has used waste seashells salvaged from the seafood and aquaculture industries to develop a sustainable material that resembles concrete.
Named Sea Stone, the material is made by grinding down shells that are destined for landfill before combining them with natural, non-toxic binders. This grants the Sea Stone a terrazzo-like aesthetic.
According to Newtab-22, Sea Stone could become a sustainable alternative to concrete in the design of small-scale products, as the two materials share similar properties. This is because seashells are rich in calcium carbonate, otherwise known as limestone, which is used to make cement – a key ingredient of concrete.
