#Building tiles made from oyster shells, fish bones can be used for coastal structures

The world has a lot of waste that is discarded in landfills or worse, in natural environments that cause damage to the ecosystem. Fortunately, there are a lot of people who are exploring how to turn these seemingly useless trash into materials for products so that they can be recycled. One of the recent winners of the Red Dot Award turned her focus on oyster shells and fish bones.

EcoShell is a sustainable building material that is made from abundant marine waste and is also visually pleasing. The durable exterior tiles are made from powdered oyster shells with binders extracted from fish bones serving as the adhesives, which makes it biodegradable too. The blend of these two materials make sure that the tiles are durable and can last for a long time.

Since oyster shells are salt corrosion resistant, this material can be used in coastal areas since they can last longer compared to other building materials. The tiles look like concrete but are actually lighter than that. It also has a user-friendly hanging system so that you can easily install it without using things like nails. The texture and color can also be customized to match the structure where it will be used.

This is an interesting way to use these usually discarded materials by the seafood industry. Millions of tons of the shells in particular are thrown away which actually pose risks to the environment especially if they are untreated in landfills or oceans. The fact that you can use them in buildings near oceans makes it part of the sustainable cycle.
