Folks,
If the only data point we had was the WMI wanted something, that would be
enough to label it as bad idea.
But if that isn't enough, just look at the actual recovery (percentage)
of gases from dumps even under favorable circumstances.
I haven't seen any data, but would think that recirculating the leachate
would increase the levels of toxins in landfill gas as well as the
release of gaseous toxins into the ambient air. I would also think
this would increase the "strength" of the leachate, which would
probably accelerate degradation of rubber/plastic liners.
An all-around horrible idea.

Eric,
You made the statement:
- Never mind that
Europe looked at bioreactors long ago and rejected them in any and all
forms as unsafe and unable to keep pollution from the environment.
When I served on a committee on the
future of materials management, I did a lot of reading of government and
research organization documents and never found such a statement. I had
hoped that you could provide such a document.

- John,

- My comment comes not from a source document,
but from my personal work experiences with European waste experts over
the last ten years. I have had the good fortune to work with some
incredible people across the ocean, and some of them may be on this list
(or lurking). I remember discussing the bioreactor situation
with them almost five years ago and they thought it was funny how one
large private corporation (Waste Management Inc) was going to take
America down a path that the EU had already decided wasn?t a good
choice.
-
- And I?m not sure you?re right that the EU
Directive came before bioreactors, although I don?t have the documents to
back me up. Do you? And I agree with Helen? the EU is
aggresively shutting down the landfill as an option over the next 10
years and the way they are doing it is to LIMIT (and nearly prohibit) the
amount of biodegradable material allowed to go in. Hmmm? I wonder
why that was their chosen strategy?

- Hi Helen ~
-
- My sense is that the EU
Directive was promulgated before the concept of bioreactors was fully
developed.
-
- It seems to me not a rejection,
per se, but selection of a different path, when fewer pathes were
available.
-
- And, the EU still allows
organics in landfills, thus those landfills still have the long term
issues related to organics to deal with.

- Interesting question raised here: since the EU Directive set limits
on the % of organics in landfills doesn't this amount to a de-facto
rejection of bioreactor landfills?

- Could you provide an official EU
or other European agency document that shows that they have examined and
rejected bioreactors "in any and all forms and as unsafe and unable
to keep pollution from the environment"?
-
- I served on a committee that
looked at accelerating the time frame at which waste disposal sites would
degrade material in them and looked at what was going on in the EU,
but was not fortunate enough to come up with any references that included
that conclusion.

- Thanks much,
