How Mushroom Farming Waste Could Benefit the Environment and Economy - Eater

"An hour south, in Hillsdale, New York, Tivoli Mushrooms produces around 20,000 pounds per week, and it’s currently only using half the capacity of its new 15,000-square-foot facility. Soon after moving in, Co-founder Devon Gilroy reached out to a neighboring organic farm, offering the spent substrate for free as compost if they would simply take it off his hands. It wasn’t a tough sell. 'They showed up like two weeks later with a tractor and a big truck to load it in,' he said. 'They insisted on paying us for the substrate, which really helped.'" - Doug Bierend
