About Us

Milorganite. For Better Results. Naturally.

Headquartered in Milwaukee, Wisconsin, Milorganite products are manufactured and marketed by the Milwaukee Metropolitan Sewerage District (MMSD), a regional government agency whose primary focus is providing water reclamation and flood management services for about 1.1 million customers in 28 communities in the Greater Milwaukee Area. Since 1926 MMSD has been a world leader in supplying Organic Nitrogen fertilizers for professional and residential use. While revenue generated through the sale of Milorganite products does not make up for the entire cost to produce and market, our belief in beneficial reuse and recycling makes producing our value added products the clear choice.
