Mobina has invented a truly biodegradable biomaterial from waste eggshells, transforming this food by-product into a sustainable resource. See her new Egshel material, with its appealing aesthetic, on the GREEN GRADS stand in the Innovation Gallery. It is relatively inexpensive, comes in various thicknesses, is mouldable and can be machined using various processes such as CNC and laser. The thin version is translucent, printable, foldable, and self-adhesive. It can even be embroidered. This material has been extensively tested for strength, compression, flex, impact and heat resistance. It diverts waste from landfill, reduces shipping emissions, and does not need virgin resources or chemically and energy intensive recycling. When immersed in water or buried in soil, it naturally decomposes within days to weeks depending on thickness. Rich in calcium carbonate, it is a natural fertiliser, completing a clean and regenerative cycle.

Mobina adds: “Materials made from unavoidable organic waste, such as residues from food production, are one of our most underutilised resources, with poor use in industrial design.”
Bio Recursive has won multiple Awards, including the inaugural Craft Council Excellence and Innovation Award. It has been included in the library of Material Source.
“I am a GREEN GRAD because sustainability shapes not only my work but also my daily life, and I am sharing my biomaterials to help others design more responsibly.”
