50,000 metric tons of fertilizer to add nutrients to soil

In the US, the city of Milwaukee’s 1.1 million residents care deeply about the quality of water they use in their daily lives.

But do they know that their wastewater is transformed into fertilizer?   Veolia has produced 50,000 metric tons of fertilizer annually since 2008 by treating wastewater from 28 municipalities in the Milwaukee metropolitan area. The fertilizer, called Milorganite (derived from “Milwaukee Organic Nitrogen”), is used to nurture the region’s lawns and gardens.

The wastewater treatment plant produces Milorganite, a nitrogen fertilizer.
