Clean Energy Technologies Inc. (CETI),Costa Mesa, California, announced a waste-to-energy (WTE) system set for completion in Tennessee later this year is mark the second commercial collaboration utilizing the Clean Cycle generator from Clean Energy Technologies (CETI). The WTE system will provide renewable electricity to a municipal wastewater treatment plant.
CETI's equipment is designed to generate more than a million kilowatt-hours of renewable electricity over the 20-year life of the project by converting 8,000 tons of waste material diverted from landfills each year, the company says. Other benefits, according to the company, include a carbon emission reduction of 2,500 tons annually. The plant has been awarded a $250,000 Clean Tennessee Energy Grant from the Tennessee Department of Environment and Conservation.
PHG Energy (PHGE) of Nashville designed and is now building the facility in Lebanon, Tennessee that will initially convert some 32 tons per day of wood waste, scrap tires and sewer sludge into a fuel gas through a patented downdraft gasification process, the company says. The synthetic gas created will fuel a thermal oxidizer and that heat energy will be transferred to three 140- kilowatt Organic Rankine Cycle (ORC) generators provided by CETY.
"We are very excited to play a major role in this system that provides clean energy and addresses economic concerns at the same time," says Kam Mahdi, chief executive officer of CETI. "The flexible system PHGE has devised can be the start of a solid foundation of reducing landfill usage, greenhouse gas emissions and electrical costs for many cities and industries."
PHGE began working with CETI's heat waste generators during a research and development deployment in 2012. At the time the Clean Cycle generator business was owned by General Electric. CETI acquired the technology in 2015.
"We have enjoyed the simplicity and reliability of the CETI equipment making it a good choice for our third project," says PHGE Chief Operating Officer Chris Koczaja. "We were able to utilize their ORC generators to prove our clean synthetic gas could be utilized to produce electricity from waste. Then we installed our first municipal waste-to-energy system in Covington, Tennessee, using the same line of equipment. The city of Lebanon, Tennessee, project will benefit from the same ease of operation, low maintenance and reliable performance."
