Articles by Jeff Ziegenbein

Ziegenbein writes occasionally for BioCycle Magazine which promote growing food in sewage sludge, calling the sludge by the PR euphemism biosolids. He co-authored an extensive article on the Inland Empire Utility Agency with composting consultant and BioCycle contributing editor Rich Flammer. The article, "A MEGACOMPOSTING SUCCESS STORY," focused on the IEUA's success at creating SoilPro Products Premium Compost, a sewage sludge product sold to Kellogg Garden Products and other distributors and garden stores as "biosolids compost".[1]
