Wastewater treatment plant to receive renewable energy from CETY technology

Clean Energy Technologies, Inc. has announced an innovative waste to energy system, set for completion in Tennessee later this year, that will provide renewable electricity to a municipal waste water treatment plant, and will mark the second commercial collaboration utilising the Clean Cycle Generator™ from Clean Energy Technologies (CETY).

CETY's equipment will generate over a million KW-hrs of renewable electricity over the 20 year life of the project by converting 8000 tpy of waste material diverted from landfills. Other benefits include a carbon emission reduction of 2500 tpy. The plant has been awarded a US$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, TN, that will initially convert some 32 tpd of wood waste, scrap tires, and sewer sludge into a fuel gas through a patented downdraft gasification process. The synthetic gas created will fuel a thermal oxidiser and that heat energy will be transferred to three 140-KW 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," said Kam Mahdi, Chief Executive Officer of CETY. "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 CETY'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. CETY acquired the technology in 2015.

"We have enjoyed the simplicity and reliability of the CETY equipment making it a good choice for our third project," said PHGE Chief Operating Officer Chris Koczaja. "We were able to utilise their ORC generators to prove our clean synthetic gas could be utilised to produce electricity from waste. Then we installed our first municipal waste to energy system in Covington, TN, using the same line of equipment. The City of Lebanon, TN, project will benefit from the same ease of operation, low maintenance, and reliable performance."
