The temperature and humidity are comparable," explains Arnaud Ulrich, co-founder of UpCycle-La boite à champignons (mushroom box), based in the Paris suburb of Saint-Nom-la-Breteche. "Thirty percent of urban waste is useful biowaste and today, only five percent of this organic matter is recycled," he notes. At that time, "Paris mushrooms" were also born from the idea of recycling organic matter. The machines swallow up organic waste from restaurants such as peelings and leftover food waste, be it meat or fish, as well as grass cuttings.
