Sludge Recycling System™

eco/Tech developed an innovative technology to co-combust different types of sludge with municipal solid waste in combustion facilities. Sludge is the semi-solid waste material removed during the treatment of municipal wastewater or from certain manufacturing operations like paper mills and can present disposal concerns for communities and industries. The commercial potential of this technology is significant for application in both existing and new resource recovery facilities, and promises to provide municipalities around the world with an environmentally sound management alternative for another waste stream.
