Alles.
We live in the city and remember well the maggot infested
garbage-pail-in-ground-out-back. We too have had GD problems in the
past. Our solution was two fold, Improve the 100 year old crusty
plumbing for the tenants, remove those GD's not needed and (our
favorite) freeze all the garbage in left over plastic bags. Disposing of
it in the trash on Wednesdays.
Works for us

The justification of this is overload on sewage treatment facilities by
stuff that would otherwise go into the trash.
Ground up stuff adds biochemical oxygen demand (BOD), which is what sewage
treatment plants remove. The more BOD in the waste stream, the more sewage
treatment plant is required for adequate treatment. Ground up stuff adds to
sludge volume also. Sludge has to be digested and finally dried. Volume
is a problem.
It is possible (note that I didn't say "theoretically" or "readily" possible)
to so overload a sewage treatment plant with BOD from a particularly strong
source, in one case a chicken slaughtering plant, that the effluent from the
treatment plant is way too strong; it may still have a substantial BOD. Stinks.
Solution in that case was pre-treatment at the chicken plant. You may not be
able to do that with domestic kitchen waste unless it is really loaded up with
blood or meat waste. Grease inhibits the bacteria that remove BOD.
But that is why.

Subject: [MBZ] Garbage Disposers Banned
So, we have a rental and as we are leaving our house yesterday evening to attend a
meeting, the resident calls to say that the kitchen sink is clogged up. Being booked
solid for the next 24 hours or so, I call a plumber to take care of the problem. He calls
after doing the job to say that sweet potato peelings were run through the garbage
disposer (GD) and bunched up in the "J bend" causing the blockage. He removed
and replaced the trap, and took out the peelings. He proceeds to say that this house was
built before the use of garbage disposers, and is not designed to have a GD. He
recommends removing the disposer and restoring the original configuration under the sink.
I am not inclined to follow his reommendation, believing it to be a desirable feature for
residents. He says that NYC and other cities have banned garbage disposers.
My question: Why have some cities banned GD's?
