Hi ZWForum, CNRCC Energy & Climate Comm & GRRN:
Just curious but what is the general feeling in the greater recycling
community about sending food waste to sewage treatment plants (POTWs publically
operated treatment works) so energy can be recovered and the end product I
assume used as a soil amendment. In the study just released below the food
waste is kept separate from other materials entering the POTW so should be no
cross contaimation with sewage sludge.
If this is a good idea, we may want to add this to suggestions we
are sending to Cool Cities as a good way for gargage and energy to work
together aka achieve both composting and energy goals and sustainability goals
(handling things close to the source) by getting each communities POTW to add
this type of process to their operations.

Subject: Anaerobic Digestion of Food Waste
Final Report Available

pleased to announce the final report "Anaerobic Digestion of
In 2006 EPA Region 9 awarded a $50,000 grant to East Bay
District (EBMUD), a wastewater treatment facility in Oakland,
to investigate anaerobically digesting food wastes from
grocery stores and other food-handling facilities at a
treatment facility. EBMUD bench-scale digesters were fed
wastes, but were operated under a variety of conditions,
digester loading rates, temperature, and other parameters. The
recovered significant quantities of energy from food waste as well
high volatile solids reduction, showing the potential of diverting
quantities of valuable food waste from landfills.
Please feel free to contact me if you have any questions.
