Harnessing Energy From Food Scraps

Leftover broccoli, unfinished hamburgers, wilted salad… sounds like a stinky mess… but it also has the potential to generate electricity. A new power plant fired up this week and you won’t find any coal or natural gas fueling its generators. This plant is powered by leftovers. Tamara Keith reports:

Leftover broccoli, unfinished hamburgers, wilted salad… sounds like a stinky mess… but it also has the potential to generate electricity. A new power plant fired up this week and you won’t find any coal or natural gas fueling its generators. This plant is powered by leftovers. Tamara Keith reports:


The Biogas Energy Project on the University of California Davis campus is the first real-world demonstration of a new technology that could change the way we think about trash.


Food scraps from San Francisco restaurants are loaded into large sealed tanks where bacteria go to work, converting the food into fertilizer and releasing hydrogen and methane gas. That gas can then be used to fuel cars, or create energy using a generator.


Dave Konwinski is CEO of Onsite Power Systems Incorporated, which operates the plant.


“We’re burying all this organic waste in landfills, but every one ton has enough power to provide the heat for 10 homes, so the numbers are staggering how much energy we can make.”


Konwinski says he hopes to make the trash to power system commercially available early next year.
