Waste to Resource

Waste to Resource

Every 2.2 pounds of mushrooms produce 11 pounds of spent mushroom substrate (SMS), a nutrient-rich byproduct often wasted through incineration. Rich in organic matter (40–60%), SMS is finding new life as animal feed, soil fertilizer, biofuels like methane and ethanol, and bioremediation materials to clean pollutants from water and soil.
