Richard Parnas of the IMS Polymer Program enjoyed a visit from Governor Danell Malloy to the site of UConn’s collaborative project with the Greater New Haven Water Pollution Control Authority and REA Resource Recovery Systems LLC on September 27, 2018. The visit celebrated the first milestone of the project, where the brown grease waste stream from the East Shore wastewater treatment plant is converted to biodiesel fuel in a process patented by Dr. Parnas that REA licenses from UConn. Dr. Parnas and REA installed a mini-refinery at the East Shore treatment plant with capability to produce approximately 400,000 liters per year of biodiesel fuel from the brown grease. That system serves as a 1/10 scale demonstration of a typical commercial system the company can install at many of the thousands of wastewater treatment plants throughout the world. For ease of installation, the entire demonstration system was constructed inside of 2 CONEX shipping containers at ProFlow, Inc. of North Haven, CT. Future plans include the installation of a turbo-electric generator to demonstrate a pathway to converting the waste stream to power at a cost much less then required with current biodigester technology.
Cong Liu, a chemical engineering graduate student working with Prof. Parnas, describes aspects of the conversion process to an aide to Governor Malloy while standing outside of the main reactor room of the mini-refinery.
Governor Malloy, Dr. Parnas, and UCONN Chemistry undergraduate Dylan Ramirez discuss the importance of waste management and power generation to the wastewater treatment industry.
