Food shall not be wasted. Though one third of the world‘s food ends up in the garbage instead of someones plate. This project aims to find kitchen applications which are able to reduce food waste. As a result of long research I developed a fruit bowl which enhances the shelf life of fresh foods and supports users to integrate a healthy diet in their daily lifes.

Fresh foods like bread, fruits or vegetables are the main reason for food waste in average households. This project mainly concentrates on storage efficiency. As research has shown there are many steps which can be done to streng-then the life of such food. Generally it is best to keep them separate, visible, dry and cool. After researching which environment fresh groceries prefer it was time to find out how consumers store their fresh groceries at home. Therefore I asked people from different social background to send me pictures from their kitchen. The results have shown that many people do not have a defined place for fresh food which does not belong in the fridge. Most fruit bowls do not really reflect the needs of consumers and of course the food itself.
After defining possible problems, the answers were clustered and organised. One possible solution is to keep food cool thanks to a naturally working evaporation cooling. When water evaporates it uses heat energy to do so. If one pours water inside a clay bowl the clay will soak up the water, which evaporates at the outside of the bowl, reflect-ed in cooling of the inside.
As tested the temperature inside a built clay unit drops as seen in the graph. The blue curve shows room temperature and the orange curve the achieved temperature drop. The up-coming product was supposed to be used effortlessly. By combining a fruit bowl with herbs, cooling activates naturally by watering your plants.
The final draft keeps all technical aspects as simple as possible to transfer the generall idea and lower production costs. The bowl is made out of clay and different plastic modules can be placed inside. One is for planting herbs. It allows a steady exchange of water to activate cooling when water is poured. The other one can be used as the actual fruit bowl. Two rows allow the user to organize fresh foods and prevent mold from spreading. The fruits remain visible, so the user can easily keep an eye on them.
If water is poured on the plant, a certain amount will be soaked up by the clay. The water will evaporate on the outside of bowl. Thereby using the heat energy of the inside, followed by cooling.
