<br /> <br /> <br /> <br /> <br /> <br /> <br />The future of wastewater treatment? No <br />chemicals and it generates energy, too. <br /> <br />A local startup has discovered how to disinfect <br />wastewater without using toxic chemicals or <br />costly electricity, while creating energy at the <br />same time. Pasteurization Technology Group <br />says it is the first and only company in the world <br />to combine wastewater disinfection with <br />renewable-energy generation. <br /> <br />The San Leandro startup is getting attention. <br />Last year PTG garnered the Popular Science <br />2011 "Best of What’s New" Award and the 2011 <br />BlueTech® Go-To-Market Strategy award. It <br />recently received a second $1 million infusion of <br />capital from EIC Ventures to expand. <br />Now the company is ramping up staffing in <br />San Leandro to keep up with the increasing <br />stream of inquiries from prospective <br />customers. <br />PTG's patented technology uses digester gas as <br />fuel to drive a turbine that generates renewable <br />electricity. <br />The hot exhaust air from the turbine (energy that <br />is typically wasted) is then passed through a <br />series of heat exchangers that increase the <br />temperature of the wastewater to a level that <br />disinfects the wastewater stream. <br />PTG's founder, 48-year-old Greg Ryan, Jr., <br />patented the technology and is bringing it to <br />market with his father, Greg Ryan, Sr. <br />The elder Ryan conceived of the idea and has <br />been involved in exploring wastewater and <br />energy solutions for years, as a farmer and <br />rancher. <br />The family had already built its own hydro- <br />electric plant on one of its ranches and in 2005 <br />was asked to construct a pilot plant for a <br />Southern California wastewater treatment <br />company. <br />T ECHLEANDRO: STARTUP CLEANS <br />WASTEWATER, MAKES ENERGY <br /> <br />February 21, 2012 <br />By: Carol Parker (excerpt from full article) <br /> <br /> <br /> <br /> <br />San Leandro, CA
