GLSD photo 3

Digesters at GLSD are squat and round--they have four.
All four can take food waste slurry along with sludge.

 

GLSD Phtoto 4

Gas from the digesters is cleaned of Siloxane and Hydrogen Sulfide before being burned.
The tanks here contain wood chips treated with iron oxide and carbon to remove each of these compounds.

GLSD Capital Projects Manager Richard Weare and
Advisory Board Chair Lou Taverna check out the intake for the food slurry tank.
