Aries Clean Technologies

Aries Clean Technologies, headquartered in Franklin, Tennessee, develops and operates proprietary fluidized bed gasification systems that transform wastewater biosolids into clean energy and beneficial byproducts. The company holds 20 patents and has diverted over 140,000 tons of biosolids from landfills and incinerators. Their core gasification technology achieves up to 95 percent volume reduction of biosolids while destroying PFAS and other harmful contaminants, producing Bio-Fly-Ash as a beneficial reuse product. Aries positions the process as carbon-neutral to carbon-negative, citing a 75 percent reduction in regional hauling emissions compared to traditional disposal methods such as landfilling, incineration, and land application. The company takes a full-lifecycle approach, designing, building, owning, and operating each facility. Their Linden, New Jersey plant achieved integrated operations in 2024 and is undergoing expansion with bond restructuring supported by Spring Lane Capital. Aries was named Technology Company of the Year by The Municipal in 2025 and demonstrated commercial-scale PFAS destruction in biosolids in April 2025. Under CEO Kari Mueller, who took leadership in April 2026, Aries serves municipalities, communities, and commercial haulers seeking sustainable alternatives to conventional biosolid management.
