Every year, 90 million tons of food are thrown away in Europe. And, in the same period, disposable crockery accounts for a further 26 million tons of garbage. Based on the assumption that, in future, every household will have a 3-D printer, Barbara Gollackner and Peter König are exploring the potential of using food waste as organic printing material. As the largest producers of such waste, how can consumers use it in a positive way? Which new materials could be created in this scenario? Stale bread (Austria’s food waste #1) is transformed into small spoons, limp carrots into little flower pots – and, as a result, the VIENNA DESIGN WEEK into a field of experimentation for 3-D printed sustainability.
