I think that we need
some hard data before we start passing judgement.

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

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

- 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,
