Biosolids Processing: Technology of Pelletization of Sewage Sludge Biosolids

Thomas J. Maestri

Synagro Technologies

Thomas Maestri has 30 years experience in project development and corporate management within the energy, environmental, and residuals management industries. Specific experience includes development and implementation of projects based on municipal and industrial biosolids treatment technologies, fluidized bed incineration, waste to energy, power generation, cogeneration, district heating, landfill gas recovery, and biogas production and use. In addition to project development, Tom has owned and operated two project development/consulting firms, managed various service companies, and managed the construction and startup of private power production facilities. Tom has also served on various boards and advisory committees, written and presented numerous technical papers, and prepared and implemented numerous technical training sessions.


As the largest biosolids management company in the country operating in 37 states under a wide range of varying conditions, Synagro utilizes many methods for treating and disposing of wastewater treatment plant residuals. With a long, 25-plus year history of Class A and Class B biosolids treatment projects in place, in recent years we have seen a constantly accelerating move toward Class A across the country. As such, heat drying and pelletization has always played a very important role in Synagro's offerings and will continue to do so in the future. Our current 10 heat drying facilities span the nation from Hawaii to Florida, the newest such facility being designed, built, owned and operated by us for the City of Philadelphia, PA. This presentation will describe the various drying technologies employed by Synagro and others, their appropriate applications, advantages, and costs. As well, time will be spent specifically describing our newest facility in Philadelphia.
