Eva:

Eva is a mini composting plant designed by Francois Hurtaud. Huge amounts of organic waste is disposed everyday in homes and restaurants. This waste can be used to produce compost, get energy and grow food. The device uses part of the waste in an aerobic process to grow plants, and part of the waste to get methane and turn it into energy, thanks to a co-generator. Energy will produce light to stimulate the growth of the plants. Everything is done in a device with a cool design.
