WARNING! Sewage sludge is toxic. Food should not be grown in "biosolids." Join the Food Rights Network.

ComPro is a product sold as fertilizer but made from sewage sludge.[1] Hundreds of communities across the U.S. sell toxic sludge products that are typically renamed biosolids and sold or given away as "fertilizer" or "compost" (and often even labeled or marketed as "natural" or "organic").

According to one website:[2]

"The Washington Suburban Sanitary commission operates several wastewater treatment plants in and around the Washington, D.C. area. Biosolids recovered from one of the plants, the Blue Plains Regional Plant in Washington, D.C., is transported to the Montgomery County Regional Composting Facility where it is processed into a valuable, marketable product, called ComPro. ComPro is sold to retail outlets in bags or in bulk to professional landscapers, contractors, grounds managers, nurserymen, and homeowners. ComPro has been used on the lawns at the White House, Mount Vernon, The Maryland Governors Mansion and the National Arboretum. The demand for ComPro greatly exceeds its supply."
