Waste seashells from the seafood and aquaculture industries are given new life with an innovative material called Sea Stone from Newtab-22, which resembles concrete or terrazzo. Sea Stone is made by grinding down shells that would otherwise be headed for the landfill and combining them with non-toxic, natural binding agents.
The concrete-like material helps to make use of the estimated seven million tonnes of seashells that are discarded annually. While many of the salvaged shells are returned to beaches, they are often uncleaned and rotten, causing pollution and unpleasant odors. With Sea Stone, these materials are repurposed in a way that amplifies their value.
As Newtab-22 sees it, Sea Stone has the potential to become a sustainable alternative to concrete in small-scale products, especially since the material shares a similar composition.
