Press Release from PR Web - Pasteurization Technology Group (PTG) -

San Leandro based Pasteurization Technology Group, is pleased to announce that it has been nominated for a Katerva Award, considered the “Nobel Prize of Sustainability” , for its patented wastewater disinfection process that generates renewable energy.

Through the Katerva Award process, the best groundbreaking ideas on the planet are identified and judged through a series of evaluation panels made up of the world’s leading experts in their field.

“We’re delighted to see our sustainable wastewater disinfection process recognized by Katerva as technology that can change the world,” said Greg Ryan, CEO and co-founder of PTG. “The findings of Katerva resonate with the numerous businesses and municipalities who tell us that our chemical-free approach to wastewater disinfection and the renewable energy it generates has many immediate applications in water management, agriculture, and the food and beverage sector.”

PTG is the first and only company in the world to combine wastewater disinfection with renewable-energy generation. PTG’s patented technology can use either the digester gas (often referred to as biogas, a natural by-product of wastewater treatment) or natural gas as fuel to drive a turbine or engine that generates renewable electricity. The hot exhaust air from the turbine or engine—energy that is typically wasted—is then passed through a series of customized heat exchangers that increase the temperature of the wastewater to a level that disinfects it. PTG’s technology is significantly more cost-effective and more energy-efficient than other methods. And, unlike other wastewater disinfection approaches, PTG’s systems do not require toxic chemicals (such as chlorine) or costly electrical power and expensive UV lamps.

The company is a fast-growing, venture-capital backed company that is revolutionizing the disinfection of wastewater. PTG’s systems feature its patented “two-for-one” technology that combines eco-friendly wastewater disinfection with the generation of renewable energy. PTG’s process is one of only a handful of technologies to pass the stringent standards of Title 22 in the state of California for the disinfection of water for reuse. By channeling the typically wasted exhaust heat from a turbine or engine to disinfect wastewater, PTG’s process is able to deliver the most energy-efficient and lowest-cost solution on the market.

PTG has won numerous awards including the 2012 Artemis Top 50 Water Tech award and the Popular Science 2011 “Best of What’s New” award. For more information, go here and follow @pastechgroup on Twitter and Facebook facebook.com/PasteurizationTechnologyGroup.

The Katerva Awards span the entire globe in both nomination and expertise.

“Katerva isn’t looking for ideas that will improve the world in small increments. We are looking for paradigm-busting ideas,” said Dr. Victoria Kamsler, chief research office at Katerva. “Our Award winners don’t simply move the needle when it comes to efficiency, lifestyle or consumption; they change the game entirely. The Katerva Award is a celebration of radical innovation and an acceleration of much-needed change.”
