The Muncher is a powerful documentary that follows inventor Mo Mohammed Momen, whose mother and neighbours died from rare cancers linked to agricultural chemicals—sparked a lifelong mission to heal the soil and protect future communities. The film traces the creation of The Muncher, a groundbreaking aerobic system that transforms organic waste into a living, nutrient-rich biological fertilizer in under an hour, and follows scientists, farmers, compost operators, and wildfire survivors as they witness its impact firsthand. By rapidly catalyzing natural soil processes, the technology produces a potent microbial inoculant that rebuilds soil structure, restores nutrients, reduces reliance on synthetic inputs, and even helps detoxify fire-damaged land. Weaving personal origin story with cutting-edge science and real-world results, the film delivers a hopeful message: by working with biology rather than against it, we can regenerate degraded land, close the loop on waste, and rediscover that the future of our food, health, and climate begins in living soil.
