N-Viro International Corporation is a publicly traded company (symbol: NVIC) that produces and sells products made from municipal sewage sludge, including N-Viro Soil and N-Viro BioBlend. According to its website:[1]

"The N-Viro technologies involve the mixing of municipal bio solids with specific alkaline waste products from the coal combustion electric generation, cement and lime industries. This process stabilizes organic waste thru pasteurization and complete disinfection."

N-Viro International Corporation went public in October 1993, when Initial Public Offering was underwritten by Robertson Stephens, Raymond James, Oppenheimer & Co., and Paine Webber.[2]

According to N-Viro's website:[3]

"Historically, N-Viro has operated an N-Viro Soil processing facility under contract with the City of Toledo. Our technology has been licensed through-out the United States and internationally with overwhelming success. Recently N-Viro acquired the Volusia County facility located in Daytona, Florida. Our Florida N-Viro facility processes municipal bio solids into N-Viro Soil from many municipalities in the central Florida area."
