About the entity

Heartland Water Technology
Heartland Water Technology, Inc. develops and markets proprietary wastewater treatment technologies. Heartland has developed an innovative direct-contact heat exchange concentrator.


Heartland Water Technology and Gruppo Pieralisi have formed a strategic partnership focused on advanced biosolids management, including municipal sludge, livestock manures and digested solids, leveraging Pieralsi's proven and robust direct-contact rotary drum dryer.

The cost and complexity of managing sludges and biosolids is growing. The vast majority of biosolids are disposed of at either landfills or incinerators, or they are land applied. Due to their high water content, strong nutrient loading, odor and difficulty in handling, these outlets are reducing the amount of biosolids they accept. As a consequence, the cost of biosolids management is going up nationally.

Earl Jones, Heartland's CEO comments, "Producers of biosolids today are looking to control their own destiny. They see outlets for biosolids disposal getting curtailed or cut-off and they want to take pro-active decisions to ensure they have a responsible and cost-effective solution for biosolids management now and in the decades to come."

An Italy-based company, Pieralisi Group has been a leader in biosolids drying in Europe and Latin America for over twenty years. Together Heartland and the Pieralisi Group will bring this proven solution to customers in the US.

Pieralisi's CEO Americas, Estela Testa says, "Requests for biosolids drying in North America are increasing and our proven technology is ideally situated for this market. In Heartland, we've found an ideal partner with the market reach and operational experience to deliver a market-leading solution."

In addition to complementary product strategies, the two companies share a common history for delivering high-reliability solutions. Says Heartland's, Ricardo Bernal, "Pieralisi's technology is a proven, robust direct-contact dryer. It's simple to operate, achieves market-superior availability, will last for decades, and always importantly, it's cost effective."

Pieralisi's Diego Rivelli comments, "Our two companies share a common belief that customers win when we deliver simple, robust technologies in a "Safety First" environment. Together, we are excited to offer a differentiated solution throughout North America."

Heartland's CEO, Earl Jones comments, "At Heartland, we see waste as valuable resource. Our mission is to help the world move away from resource disposal through technology-enabled resource recovery. We've been doing this for years with our Heartland Concentrator™, and now with our partnership with the Pieralisi Group, we expand our ability to make an impact through biosolids resource recovery and gain a world-class partner to join us for the journey."
