Aerial photo taken August 2, 2021. The Cake Storage Facility with it’s signature blue canopy is at the lower left. The slab for the Solids Building is to the right of that with the chemical storage tanks and the new belt filter presses still under wrap. Above the Solids Building is our new Cambi Thermal Hydrolysis Process equipment (steel vertical tanks) which was delivered to the site last week.
