About Sewage Sludge

Branded products containing sewage sludge

The majority of sewage sludge is hauled away in trucks and disposed of on American farms. Some is given away or sold as “compost.” Some is dried and made into pellets, bagged, and sold as fertilizer. And sometimes sludge is “blended” into bagged fertilizers. There is no labeling requirement. Sometimes the product is called “biosolids,” sometimes not.

If sewage sludge -- whether “treated” or not -- is used as a fertilizer on crops, the food from these crops cannot receive USDA organic certification. But there is no federal rule that forbids non-organic fertilizers from using the term “organic.” The grower must know what he or she is putting on his or her fields. Gardeners, too, have to do some investigative work if they buy compost or fertilizer.
