RotterZwam is an innovative oyster mushroom farm based in an abandoned tropical swimming pool. Siemen Cox en Mark Slegers started the company with the philosophy that waste is a human concept. “We need to look and learn more from nature to have a sustainable society. RotterZwam therefore collects one ‘waste’ stream (coffee) from the city and we make five new products out of it without having waste ourselves. After the mushrooms have formed we are looking into washing the enzymes out of the substrate. Those enzymes can be an important link in producing bio ethanol and bio plastics. After that we compost the remains with worms. Worms can eat their bodyweight in a day. We have specialized worm farms that consume up to 2 kg of organic waste per day. A set up of 8 farms can consume 5.000 kg per year without the need of heavy transportation by garbage truck.” At Northside Siemen will share everything he knows and all the mistakes he made so others that want to start a mushroom farm don’t have to make them.
