PTG is experiencing rapidly growing sales demand from the food, beverage, agriculture, and oil and gas industries, as well as municipalities.

2012 CLEANTECH FORUM BOOTH #108: Greg Ryan, co-founder and CEO of Pasteurization Technology Group (PTG), is presenting on Tuesday, March 27 in the Cleantech Forum Entrepreneur Showcase at the Tenth Annual Cleantech Forum. Mr. Ryan will outline how PTG’s renewable-energy-based approach to wastewater disinfection can provide businesses across a range of industries with significant cost savings while also recycling valuable wastewater.

In an era of increasing costs associated with the scarcity of water, companies can improve their profitability while also reducing their environmental impact. PTG’s technology enables businesses to disinfect wastewater for reuse while offsetting their power bill by generating renewable electricity. In addition, by reducing the need for fresh water usage by industry, precious water is made available for other uses.

PTG is experiencing rapidly growing sales demand from the food, beverage, agriculture, and oil and gas industries, as well as municipalities. After receiving $1 million of venture capital funding earlier this year, the company is poised for growth and is accelerating its product development and commercial activities. Last week, PTG expanded its product line with announcement of a mobile wastewater disinfection system that enables businesses and municipalities to fast-track pilot studies and quickly determine the cost benefits of PTG’s technology for their applications.

PTG’s technology enables reuse/recycling of wastewater and generates renewable energy

PTG is the first and only company in the world to combine wastewater disinfection with renewable-energy generation. PTG’s patented technology can use 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. 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 lamps.
