The Weekly BioDIGESTer: 11/19

In addition to the weekly operational statistics, this week’s bioDIGESTer shares an article highlighting the  project’s dual goal in serving as a teaching and learning tool as well as an opportunity for critical study through the Campus as Lab program. 

Weekly Data: 11/19 – 11/21 (Thanksgiving week)

With Frist Campus Center being closed most of the week for Thanksgiving recess, we only had two load/off-load sessions v.s. our normal three per week. Accordingly, last week’s load of food scraps was about 1/3 less than in previous weeks.

Food Wood shavings (BA/CS) %
Compost Off-loaded
Week Totals (lbs.) 2,275 687 30% 3,000
CUMULATIVE (lbs.) 23,350 6,820 29% 16,000

CAMPUS AS LAB: Biodigester as a teaching tool and area of study

The biodigester is one of many models across campus that allow students in the class to learn about global issues through a local lens by examining the sustainability initiatives and challenges at the University.

From the piece:

“If we evaluate the feasibility of a biodigester at the University, we can share our knowledge with other organizations seeking solutions to food waste,” Weber told the class. “A system like this also is an example of Princeton’s campus-as-lab approach, providing research and teaching opportunities for faculty and students.”
