State Summary

● Detroit and other Michigan municipalities put a lot of biosolids to agricultural use. Landfill disposal is also common; historically, incineration was used for a large portion of Michigan’s biosolids, but that has diminished substantially.

● Detroit’s Great Lakes Water Authority (GLWA) dominates biosolids production. The amount of land application of biosolids from GLWA in Michigan varies from year to year; in 2018 most of its new dried pellet fertilizer was shipped to Canada for land application. More has been applied in Michigan in recent years.

● PFAS started becoming a significant issue for several Michigan WRRFs in 2018, with Class B land application programs suspended/impacted. Michigan has been a leader in addressing the issue proactively.
