[USCC] Using wastewater digesters for food waste diversion

[Brian Mathews]

Michelle,

East Bay Municipal Utility District (EBMUD) and Sacramento Municipal
Utility District (SMUD) have looked into this.  EBMUD has had a pilot
for about a year and are patenting a system for cleaning up the material
before it goes to the digester with the expectation of expanding the
program.  The material needs to be relatively clean and they do not take
contaminated paper products.  The system is some what sensitive to grit
which wreck havoc on pumps and they appear to have overcome this
obstacle.

Give me a call if you want more info.

Greetings to all,

I am looking for municipalities or individuals who have had experiences
with
the digestion of food waste through a waste water digestor system.  With
the
closure of our cannery system here, we have excess capacity at the
treatment
plant (which we manage), and a zero waste goal.  I need to do some
research
to see how we might proceed with moving material into the system.  

Our treatment plant engineers are ready to try it, so they are looking
at
the loading and facility side.  I would like more information on the
logistics of food waste generation, transportation, composting, etc.
Any
contacts will be helpful.

Cheers  Michele Young
