Biosolids Recycling: Restore, Reclaim, Remediate
Video Presentation
Hosted by U.S. EPA
Technology Innovation Office (TIO)

Sewage treatment results in wastewater being recycled to the environment, but the solids removed from wastewater can also be processed and turned into a nutrient rich fertilizer. Today's primary use of this fertilizer is to restore overworked agricultural soils, but research by the USDA and the USEPA/ERT has now opened the way for use of biosolids to reclaim lands destroyed by mining. Biosolids, prepared in site-specific mixtures, are used as soil amendments and slow release fertilizers which bind the contaminating metals and jump-start plant growth in the destroyed areas. This technology is being field tested in the Leadville mining region in Colorado and the Bunker Hill area in Kellogg, Idaho. Results from these tests are verifying the promise of this technology—combining two wastes, sludge and wastelands, and creating viable, healthy soil. Running time is 15 minutes.
