Organic Waste-to-Energy

Converting Dairy Waste to Renewable Energy and Clean Water

Investment firm and power company partner to develop anaerobic conversion of Ben&Jerry dairy waste to 1MW of renewable energy into Vermont grid.

Leyline Renewable Capital announced a partnership with PurposeEnergy to 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.

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."
