When architecture student Moemen Sobh, whose family have been fishing in Port Said for generations, discovered that tonnes of fish waste was thrown to the Mediterranean Sea every year, he considered turning the unwanted fish skins into something useful. This led to the creation of Visenleer, a fish-skin leather that makes use of this byproduct and allows fishermen to make more money per fish sold. Moemen’s vision for this biomaterial ranges from producing clothing items to tents. He also uses the project to teach school and university students about sustainability goals and best practices. Moemen was mentored by London-based artist and experience designer Nelly Ben Hayoun as part of The World Around Young Climate Prize.
