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.

Final Report Available Greetings,
The US EPA, Region 9 Office of Pollution Prevention and Solid Waste
is
pleased to announce the final report "Anaerobic Digestion of
Food
Waste."
In 2006 EPA Region 9 awarded a $50,000 grant to East Bay
Municipal
District (EBMUD), a wastewater treatment facility in Oakland,
California
to investigate anaerobically digesting food wastes from
restaurants,
grocery stores and other food-handling facilities at a
wastewater
treatment facility. EBMUD bench-scale digesters were fed
only food
wastes, but were operated under a variety of conditions,
varying
digester loading rates, temperature, and other parameters. The
project
recovered significant quantities of energy from food waste as well
as
high volatile solids reduction, showing the potential of diverting
large
quantities of valuable food waste from landfills.
Please feel free to contact me if you have any questions.
Thank You, Cara Peck U.S. EPA Region 9 Office of Pollution
Prevention and Solid Waste (415)972-3382 Peck.Cara@no.address
Recycling: It is not just about landfill
diversion, it is about
replacing virgin material production which will
significantly reduce
energy consumption and greenhouse gas
emissions.
