Clay Refrigerator Cools Through Evaporation Solution by: Mitticool

The Mitticool refrigerator is made of natural clay and runs without electricity, serving as an affordable cooling alternative for rural communities in developing countries. The Triple Bottom Line

Environmental This refrigerator, made from a natural material, is an alternative to highly energy consuming cooling devices.

Social The solution offers a reliable cooling option for people living in rural areas, making it possible to secure a healthy and nutritional food supply.

Economic The Mitticool refrigerator has no maintenance costs and a significantly lower fixed cost in comparison with its electrified competitors.

This solution works on the principle of evaporation. Water from the upper chamber drips down the side and evaporates, removing heat from the inside and leaving the chambers cool. Using only water, it is possible to keep food, vegetables, and milk naturally fresh for days. The refrigerator is made of white clay and has a simple design that eliminates the need for maintenance. In areas with electricity shortages and frequent blackouts, the Mitticool refrigerator offers a reliable cooling storage option. Why a Sustainia100 solution? According to the UN Food and Agriculture Organization, much of the post-harvest loss of fruits and vegetables in developing countries is due to the lack of proper storage facilities. Most refrigerated cooling options are expensive to buy and run. Furthermore, according to consumer reports, the refrigerator is the most power-consuming device in a typical household. 1 Mitticool addresses these challenges by offering a low-cost alternative that is simple and does not require any external power supply. This makes the solution viable in rural areas with poor electricity infrastructure.

The upper chamber of the Mitticool refrigerator is used for storing water that drips down the side and evaporates, drawing energy from its surroundings to produce a considerable cooling effect.
