Sludge To Fertilizer



The process being used to deal with our waste water is very efficient. After waste water is treated, digestion then occurs in 12 distinctive egg-shaped anaerobic digesters, each 90 feet in diameter and approximately 130 feet tall. Mimicking the stomach's natural digestion process, microorganisms naturally work to break sludge and scum down into methane gas, carbon dioxide, solid organic byproducts, and water. Digestion significantly reduces sludge quantity.

Where in Quincy is this, Slim?

The egg shaped digestors are located on Deer Island. The resulting sludge is sent via tunnel to the fertilizer plant which is located in the old Fore River Shipyard.
