Leyline Renewable Capital Partners with PurposeEnergy to Convert Ben & Jerry’s Dairy Waste into 1 MW of Renewable Energy


Leyline’s funding will enable PurposeEnergy to convert Ben & Jerry’s dairy waste and ice cream into clean water and power for up to 1,000 homes

DURHAM, N.C., May 18, 2021 – Leyline Renewable Capital, a leading provider of pre-construction debt and equity capital for renewable energy development, announced a partnership with PurposeEnergy, a developer that designs and operates industrial wastewater treatment systems that convert organic residuals into renewable energy and clean water.

Leyline’s funding will facilitate the development of the SAINT project in St. Albans, Vt., that will anaerobically convert industrial food waste, including Ben & Jerry’s high-strength dairy waste and depackaged ice cream, into 1 MW of renewable energy and clean water.

The SAINT project will break ground this year and start processing ice cream waste in fall 2022. Once in operation, the project will generate enough renewable energy to power approximately 1,000 Vermont homes and will sequester phosphorus, preventing it from entering the Lake Champlain watershed. Excess phosphorus can cause algae blooms, reduce water clarity, create odor, and harm aquatic life, which reduce recreational use of the lake and impact tourism and the environment in the region.

“By providing development-stage financing to PurposeEnergy, Leyline is supporting an initiative that will not only allow PurposeEnergy to generate renewable energy for the Vermont grid, but will benefit the entire St. Alban’s business community,” said Erik Lensch, CEO of Leyline.

PurposeEnergy will construct this anaerobic pre-treatment plant adjacent to the Ben & Jerry’s production site, which will be connected via a buried three-inch pipe that will receive Ben & Jerry’s byproducts for treatment, eliminating the need for hundreds of waste tanker trucks each year. In order to maximize power output from the digesters, PurposeEnergy will blend other feedstocks, including depackaged food waste, chocolate, and cheese byproducts, with the ice cream. As a result, other businesses in the community can also use the digesters to process their byproducts, while saving money and reducing their carbon footprint.

“PurposeEnergy hopes to revolutionize the way food and beverage production facilities process, utilize, and reclaim organic waste,” said Eric Fitch, founder and CEO of PurposeEnergy. “We are grateful that Leyline provided us with the critical capital we needed to get this project started, as well as the guidance we needed to initiate the SAINT project and help Ben & Jerry’s manage its byproducts in a sustainable way.”
