BALTIMORE, Maryland, November 29, 2023 –  Synagro Technologies, Inc., the preeminent provider of biosolids and residuals solutions services in North America, today announced that it has acquired New England Fertilizer Company (NEFCO), a Massachusetts-based, privately-held company with customized client solutions and proven biosolids management technologies.

“We welcome the NEFCO team to the Synagro family,” said Bob Preston, chief executive officer, Synagro. “I am delighted to add their passionate people, leadership, proven capabilities, and network of facilities to our growing company. As we grow, we have a greater and more positive impact on the environment, society, and people.”

The acquisition of NEFCO increases the company’s industry leadership in beneficial-use capabilities of biosolids from thermal drying facilities. The complementary portfolios also provide Synagro with additional capacity and an enhanced set of innovative client solutions to meet growing customer needs.

“Joining the Synagro team was a great decision for the combined business as well as providing additional opportunities for our employees,” said Larry Bishop, general manager, NEFCO. “We are excited to be part of such a great team, with our proven capabilities working together to provide innovative client solutions.”

This is a strategic acquisition in the sustainable growth of Synagro and follows three recent acquisitions all aimed at driving leadership, growth, and long-term financial value.

As the largest recycler of organic by-products in North America, we’re trusted because we remove risks while keeping the logistics clean. Because we have the most experienced team in the industry, we can offer tailored solutions that ensure no waste goes to waste. Much of our work isn’t pretty.
