How is Milorganite® Fertilizer Made? | MMSD

Milorganite is made using one of the nation’s oldest recycling efforts. Instead of recycling plastic and glass, we recycle nutrients. Wastewater enters the Milwaukee Jones Island water reclamation facility, where all solid materials such as sand, boards, shop rags, plastic, and debris are first removed. Microbes are added to the water—the activation process—and oxygen is bubbled through the water to create the ideal environment for the microbes to digest the nutrients in the water. The microbes die after they consume all of the nutrients. Binding agents are added to the water causing the microbes to clump together and settle to the bottom of the undisturbed water in sedimentation tanks. After everything has settled, the cleaned water is returned to Lake Michigan, and the microbe clumps are sent on for dewatering and drying. Moisture is first squeezed out of the clumps using belt presses, resulting in something similar to wet cardboard. The semi-solid material moves on to one of 12 rotary kiln driers heated to 900–1200 ⁰F, which heats the Milorganite to an internal temperature of 176°F. The extreme heat kills pathogens. Milorganite is analyzed for at least 20 parameters every day to comply with all applicable safety guidelines for protecting human health and the environment. After passing all tests, it’s ready to be packaged and shipped throughout the U.S.A. https://www.milorganite.com/what-is-m...
