Aries Clean Energy has secured approval to build its first large-scale fluidized bed gasification system, engineered to convert 400 tons of biosolids per day into 7 million to 7.5 million cu. ft. of renewable, low-Btu synthesis gas plus 22 tons of biochar, the latter a raw feed for processing a concrete-grade fly ash substitute.

Built at the Linden Roselle Sewerage Authority (LRSA) complex in northern New Jersey, the Aries Linden Biosolids Gasification Facility will consume the system’s synthesis gas in lieu of fossil fuel. Project officials also cite greenhouse gas emissions reduction from curtailing the trucking miles and methane associated with conventional biosolids transfer and land application.

“[Our] patented gasification system eliminates the need for environmentally harmful landfilling or incineration of biosolids, while producing beneficial renewable energy and biochar,” says Aries Clean Energy CEO Gregory Bafalis. “We believe this is a beneficial and disruptive technology that will revolutionize the wastewater treatment industry and establish itself as the best available control technology for biosolids disposal.” In a nod to LRSA and the New Jersey Department of Environmental Protection, he adds, “The awarding of these permits further validates Aries patented technologies will bring clean and renewable solutions not only to the Garden State, but worldwide.”
