The Piscataway Bioenergy Project is the largest and most technically advanced project ever constructed by WSSC which will employ innovative technologies to recover resources and produce green energy. In the coming years, the Piscataway plant will evolve into a bioenergy production facility that uses efficiency, technology and sustainability to enhance the financial and environmental health of the region. This $262 million project will serve customers for the next 100 years.
The Bioenergy Project will transform how WSSC handles biosolids — the nutrient-rich organic materials resulting from the wastewater treatment process — from five existing WSSC water resource recovery facilities). Using cutting-edge “green” technology, the new facility will significantly reduce the amount of biosolids left over from the treatment process, thus reducing costs to haul and dispose of the product. The remaining biosolids will be significantly cleaner (Class A), making the disposal process much easier and allowing the final product to be sold and distributed as fertilizer. With cleaner Class A biosolids, WSSC will also save money by eliminating the use of lime, which is currently applied to Class B biosolids to control odor.
As an added benefit, the process to create the Class A biosolids will generate renewable fuel to help run the plant. This new process produces methane gas providing green energy that will help run the Piscataway Water Resource Recovery Facility.
