"Waste is a design flaw."- Kate Krebbs

Eggware is new ceramic & concrete like tangible that is made out of calcareous food waste -"eggshells" and a biobinder- "alginate." On an average, 200eggs/year are consumed per person, globally, so one can image the amount of unutilized resource that is discarded extensively. Midushi Kochhar, its maker, saw an opportunity in this waste flow and experimented meticulously to create a tangible that is naturally white, lightweight, rigid, powdery, water-absorbent and quite strong.

With applications in tableware, it can also be used in construction, interior tiling and craft objects, 3D printing etc. Once their purpose is complete, these products can literally be crushed and thrown away in the compost adding protein and other nutrients to the soil. Moreover, it has low propagation of fire, which means that the material self-extinguishes!

There is lots that we humans still need to learn from nature’s technology through biomimicry, and designing explicitly with the end-of-life in mind, so we can shape materials, products, and spaces that are truly regenerative for the planet. By valuing and employing natural waste streams, Midushi tried to drive a positive change through value addition to a classed waste resource, spreads awareness about climate and food crisis related issues and finally, revise the common perception about our precious waste capital.

Additional information

Waste eggshells were initially collected from the busy breakfast cafes around King's Cross, London but currently being retrieved from roadside food stalls. It is a strange yet intriguing interaction between the chefs and the maker as the restaurateurs feel surprised by the innovative possibilities of the waste they produce.
