Trident Processes has been selected as the nutrient recovery technology provider for a new anaerobic digestion (AD) facility in Salisbury, Vermont.

Construction is underway for Vanguard Renewables' new farm-powered biogas facility at Goodrich Family Farm's dairy. Once the facility has been built in Q3 2020, the facility will process 280 tons of manure and organic waste per day into renewable natural gas (RNG).

Trident's nutrient recovery system will process the digestate and extract nutrients and clarified water. Its system can produce 50,000 gallons of treated water every day and will help to manage the farmland's phosphorous levels.

"Traditional manure storage and handling is a big expense for dairy farms, and it presents substantial environmental risks," said Kerry Doyle, CEO of Trident. "Nutrient recovery is a key tool for watershed and soil conservation and we are excited to work with Vanguard Renewables and Goodrich dairy to help make their vision a reality."

Shawn Conley, sales director at Trident, added: "Nutrient recovery is very effective in reducing nonpoint source agricultural waste discharges. The dairy will be able to better utilise nutrients specifically to the needs of their land and reduce reliance on chemical fertilisers."
