If the average cow produces 100 pounds of manure a day, how does a dairy farmer manage all the excess waste? Tom Herlihy, an agricultural engineer, created a unique and environmentally friendly technology to deal with this very problem. Herlihy employs 8 million earthworms in a state-of-the-art facility to transform manure into an environmentally friendly, all organic fertilizer called Worm Power. The worms eat the organic matter and generate castings that serve as a nutrient-rich, natural fertilizer.
