The eco/Tech Sludge Recycling System: Two Years of Experience

The eco/Technologies Sludge Recycling System (eco/Tech SRS) was introduced at NAWTEC 10 and has now been operating commercially for two years at the Pioneer Valley Resource Recovery Facility (PVRRF), located in Agawam, Massachusetts. A second system will be installed at the Pittsfield Resource Recovery Facility (PRRF), located in Pittsfield, Massachusetts, in 2004 and EnergyAnswers is now marketing the system to other power plant owners. Presented in this paper is an overview of: • Operating and maintenance history at PVRRF; • Market conditions and challenges; • Air emissions results; • Design enhancements planned for PRRF. The data presented support the potential for waste-to-energy plants, and by extension all solid fuel power plants, to benefit from additional revenue streams while using a waste product to achieve air emissions reductions.
