Transcript of Pyrolyzer
coming to my Indiana hometown, Logansport
You can follow this at your own pace
(and dive into more detail)
Definition of pyrolysis/combustion unit from the
Code of Federal Regulations:
None of this makes sense.
Question and Answer
(1/4 how much trash all of Indiana produces)
limit emissions in Cass County:
call your Commissioners at
Write letters to
Pharos-Tribune P.O. Box 210 Logansport, IN 46947
(and things in trash : http://www.niagarafallsreporter.com/Stories/2013/Aug06/rats.html)
Help call out Mayor Franklin, the City Council, and the consultants by bringing attention to this absurdity.
(a tiny fraction of one bag)
Scale - It does seem that there are incinerators which are well within 50% of the size proposed. Why did those systems get excluded from the presentation materials?
Yes, some mass-burn incinerators are a bit over 50% the size of this proposal. And, if you look at their tons-per-day and their electrical output, then it is plausible that Pyrolyzer would be able to produce 150 MW for Logansport. However pyrolyzation facilities are less efficient than mass-burn facilities if only because of the added expense of sorting and sizing of the fuel that must be done first. The sorting and sizing is not perfect, and that leads to breakdowns. I have found a few relatively tiny pyrolyzation facilities that seem to run fairly continuously, but their fuel is homogenous (scraps from a plastics factory, for example), and I have not found evidence of electricity production (much less how efficient it is).
Europe currently incinerates 22% of their trash and it is generally considered a great thing for the environment and conservation of energy. As Logansport currently uses coal, this could only mean a huge decrease in environmental impact. What is the real environmental concern, what is the basis for it, and what mitigations do you think should be taken?
Flanders they have required continuous monitoring of
Dioxins, with the result that you would expect--the operator of the plant takes pride in tweaking the operation to make emissions as low as possible. In the U.S., the EPA only requires one dioxin test per year, and the operator is free of other emissions limits in the two
weeks preceding the test. We have asked our County Commissioners (Indiana allows local govt. to enact stricter AIR emissions than the EPA has) to limit dioxin to half what any other large incinerator could emit, and three more to the limits that a natural gas plant may
emit. This would be an improvement. However emissions limits are expressed as percentages (for example, "parts per million"), so it is important to consider the total tons of emissions per year coming out
of the stack.
Whatever is in the trash will go somewhere. Think about things that normally go into
trash that you would not want to breathe or eat; weed killer bottles, diapers, Styrofoam, metal liners in juice boxes, batteries, drugs, etc. It may seem odd to think of these things being inhaled or drunk, but all those pollutants do not just disappear. They must be either chemically transformed or captured (and concentrated) by pollution controls.
Rats are a problem for another municipal solid waste facility
40 CFR 60.51b:
Municipal waste combustor, MWC, or municipal waste combustor unit: (1) Means any setting or equipment that combusts solid, liquid, or gasified MSW including, but not limited to, field-erected incinerators (with or without heat recovery), modular incinerators (starved-air or excess-air), boilers (i.e., steam-generating units), furnaces (whether suspension-fired, grate-fired, mass-fired, air curtain incinerators, or fluidized bed-fired), and pyrolysis/combustion units.
Pyrolysis/combustion unit means a unit that produces gases, liquids, or solids through the heating of MSW, and the gases, liquids, or solids produced are combusted and emissions vented to the atmosphere.
“A municipal waste incinerator 'combusts' solid waste and thus is functionally synonymous with municipal waste combustor.” (www.epa.gov/ttn/nsr/gen/rm_2.html)

Pyrolyzing the fuel--in this case trash and tires--is in one container, resulting in a flammable gas, char, oils, and/or ash.
That's not all you get from pyrolyzing trash and tires, but don't have time to go into all that right now.
