Community-Powered Sustainability: North Torrey Pines Anaerobic Digester

 

The North Torrey Pines Anaerobic Digester (AD) turns pre-consumer food waste from the Sixth College Restaurants into renewable biogas and liquid fertilizer.

More info coming soon!

What is anaerobic digestion?

Anaerobic digestion is a process through which bacteria break down organic matter in the absence of oxygen. Anaerobic digestion for biogas production takes place in a sealed vessel called a reactor, which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These reactors contain complex microbial communities that break down (or digest) the waste and produce biogas and digestate (the solid and liquid material end-products of the AD process) which is discharged from the digester. 1
