This expansion secures Synagro’s leadership position as North America’s largest biosolids and wastewater residuals solutions services company.

BALTIMORE, Maryland, June 27, 2024 – Synagro Technologies, Inc., the preeminent provider of biosolids and wastewater residuals solutions services in North America, has announced the achievement of commercial operations at its newest composting facilities. The Cumberland County Biosolids & Organics Recycling Center in Deerfield, New Jersey, will serve the greater-New Jersey markets, and the Holly Hill Composting Facility will serve the Charleston and Columbia, South Carolina, markets. These facilities represent more than a $50 million investment which is in line with the company’s strategy to further expand composting in the eastern United States.

“We are excited to announce commercial operations at these new composting facilities,” said Pam Racey, Chief Commercial Officer, Synagro. “They are great examples of how we are executing on our company’s strategy to grow sustainably.”

The Cumberland County Biosolids & Organics Recycling Center is a state-of-the-art 103,000-square-foot, in-vessel composting process building, utilizing automated aeration, and turning equipment. New Jersey generators will be able to leverage Synagro’s investment in green infrastructure for biosolids and organics management thereby producing approximately 38,000 tons of Class A compost annually. Synagro has teamed with the Cumberland County Improvement Authority to provide the facility with renewable energy, creating a highly sustainable, environmentally and community-friendly solution.

“Synagro considered multiple technologies before selecting composting for the Cumberland County facility,” said John Goodwin, Senior Vice President of Technology, Synagro. “Our choice of an in-vessel composting process was driven by the desire to utilize proven technology with a demonstrated ability to produce a high-quality product while maximizing the environmental benefits of the facility.”

The Holly Hill Composting Facility is ideally situated on 25 acres offering a much-needed, cost-effective sustainable composting option for the region, removing 75,000 tons of biosolids annually from local landfills. This outdoor, windrow-style, woodchip-and-biosolids feedstock composting facility will produce approximately 40,000 tons of Exceptional Quality compost annually. This compost product will be used in local agricultural and soil-blending operations thereby completing the biological cycle of our circular economy. Additionally, this facility will utilize Synagro’s own SynaPureTM wastewater treatment system to provide clean runoff water from the site.

Both facilities will produce AllGro® compost – a nutrient-rich, sustainable, all-in-one soil amendment. AllGro compost brings agronomic value to almost any application by providing benefits such as increased yields, replenishment of organic matter, water retention and slow-release plant nutrients which reduce the need for chemical fertilizers.
