inCase boxes are a smart solution to save space inside the fridge, indeed they occupy part of the external shell. The project driven by Sapienza University, spread by the challenge to let home appliances more efficient. The PLA in which the boxes are made gives a soft tactile sensation and reflects the aim of a sustainable design. Each case is conceived to take advantage of the properties of the vegetables that it contains. Saving food from the fridge let consumers open it less times during the day and the space occupied by the boxes helps the fridge to disperse the heat produced by the refrigeration process.
