PTG is the first and only company in the world to combine wastewater disinfection with renewable-energy generation. PTG's patented technology utilizes the digester gas (often referred to as biogas, a natural by-product of wastewater treatment) as fuel to drive a turbine that generates renewable electricity. The hot exhaust air from the turbine (energy that is typically wasted) is then passed through a series of heat exchangers that increase the temperature of the wastewater to a level that disinfects the wastewater stream.
By solving two problems for the price of one, PTG's technology is significantly more cost-effective and more energy-efficient than other methods. Unlike other wastewater disinfection approaches, PTG's systems do not require toxic chemicals such as chlorine or costly electrical power and expensive lamps in the case of UV. PTG's robust technology is a timely solution for municipal wastewater treatment facilities, many of which are at capacity and preparing for increasingly stringent water-quality regulations. The company is also experiencing strong demand from the food, beverage, and oil & gas industries.
"For 24 years, Popular Science has honored the innovations that surprise and amaze us - those that make a positive impact on our world today and challenge our views of what's possible in the future," said Mark Jannot, editor-in-chief of Popular Science. "The Best of What's New Award is the magazine's top honor, and the 100 winners - chosen from among thousands of entrants - represent the highest level of achievement in their fields."
"We believe that two of the most important problems facing the planet over the next 100 years will be water and energy - scarce resources that require innovative approaches to maximize re-use and harness renewable energy," said Greg Ryan, co-founder and CEO of Pasteurization Technology Group. "We are thrilled that Popular Science has bestowed this award on PTG as it confirms the fantastic response we have been getting from customers across multiple industries." – less–ZoomInfo
