Trash-To-Gas Power Plant Gets Greenlight 113

An anonymous reader writes "Beginning in a little more than a week, Green Power, Inc. of Pasco, Washington will be commencing the building of municipal-solid-waste-to-fuel plants for clients around the world, with $2 billion in contracts; now that an EPA ruling has exonerated GPI from an unnecessary shut-down order by the Washington Ecology Department last year. This fuel would be of higher quality and cheaper than fuel derived from crude oil — and it comes from local feedstock, while turning waste into energy. Now your laptop can turn into a quart of diesel fuel to power your trip to the dump. And the ocean gyres of trash the size of Texas can power Texas.

        Well, I wonder what the energy cost of the conversion is: for any cracking of hydrocarbons, you need some energy input, and (in all probability) you'll end up losing some of the input mass to by-products. My questions with these kinds of "waste to energy" methods are,

This was cleared on September 8, 2010 by an EPA ruling that support's GPI's claim and reverses Washington state's Ecology Department's claim that placed the GPI process in the class of incinerators, which it is not.

      According to the EPA:

      Green Power describes its process as a proprietary catalytic pressure-less depolymerization process (CDP) where municipal solid waste or a wide variety of organic wastes are 'cracked' at the molecular level and the long-chain polymers (plastic, organic material such as wood, etc.) are chemically altered to become short-chain hydrocarbons with no combustion. Combustion requires oxygen or a similar compound, but according to Green Power the CDP occurs in an anaerobic environment, exposed only to inert gases like nitrogen.

  • What I always wonder about with these waste-to-energy-it's-like-incineration-but-not-that-bad-kind-you-remember schemes is what happens with waste that is nasty on the level of the elements it contains, rather than just chemically.

That seems more direct. All the stuff that would have to be caught by smoke scrubbers, where does it go in this liquid fuel plant?
      • In theory this process could be a lot better, since the point is to break the polymers in the waste down into simpler hydrocarbon chains and then burn only those. At least that's my understanding. All the nasty stuff either gets degraded down into simple hydrocarbons and burns (cleanly) or is left behind as solid or liquid residue, which you can then dispose of.

This was cleared on September 8, 2010 by an EPA ruling that support's GPI's claim and reverses Washington state's Ecology Department's claim that placed the GPI process in the class of incinerators, which it is not.

    So the government of my state caused major problems for GPI, and the federal government had to overrule the state. That's just great.

    According to TFA, GPI's plant operates using "a proprietary catalytic pressure-less depolymerization process (CDP)" yet the state Department of Ecology (DoE) insisted on regulating the plant as if it were an incinerator plant, which it clearly isn't.

    We have a liberal Democrat for a governor, the Democrats have a complete lock on the state legislature, and plenty of liberal voters. Our governor claims to be in favor of the environment, in favor of business that helps the state, in favor of jobs, etc. Where was she when the state DoE was causing these problems?

    I really wonder at the politics behind this. If this is random bureaucrats just being pointlessly bureaucratic, why didn't any other part of government get involved and help resolve this? Where were the state senators and representatives from the Pasco area? Did the governor just never hear of this, and if so, how is that possible?

    If I were governor and something like this happened, I would very publicly intervene. There's no political downside! The governor has more power than bureaucrats at the DoE, and the voters would love to hear that a green energy project was helped out. So why didn't that happen?

    P.S. This of course reminds me of the other thermal depolymerization [wikipedia.org] plant, the plant in Carthage, Missouri [discovermagazine.com] that processed turkey offal into energy and fuel. That plant was shut down several times, over allegations of a bad smell; the bad smell was reported at least once on a day that the plant wasn't operating. Eventually they installed upgraded scrubbers on their exhaust stacks and resumed operation. The company, Changing World Technologies [wikipedia.org] went into Chapter 11 bankruptcy [gigaom.com] and I guess the TDP plant was shut down. That seems crazy to me; the price of crude oil is high, so they should be able to run their plant at a profit. I guess they are just in too much trouble financially to even run the plant right now?

    I hope this "CDP" plant in Pasco works out better than the Changing Worlds one did.

        There are plenty of so-called businessmen out there with grandiose plans of converting biomass to energy without any pollution. Unfortunately, this sounds like one of them.

        If you read the related links, you will see that GPI really can produce a quality product; according to this page [peswiki.com] you can take the output of their test plant and pour it into the tank of a diesel truck and it will just work. And if you read the claims, it seems it doesn't pollute the air while doing it (impurities from the input stream come out the far end as some sort of solid). Some combustible gas is produced as a by-product of the reaction (methane, I guess) and they plan to burn that to provide power to operate the plant, making it self-fueling. (The same thing is true of the Changing Worlds plant that converts turkey offal to oil.) In short, if these web pages are true, GPI is not making "grandiose claims" that aren't true.

        Also, GPI seems to have some real problems paying bills on time. That has nothing to do with the technology. (And the Washington state DoE shutting them down didn't exactly help GPI to pay their bills on time.)

        It seems the DoE shut them down because the DoE believes that GPI should have filed some paperwork related to burning trash. GPI went to the federal EPA and got a ruling [pesn.com] that their process does not fall into the category of burning trash, and thus the DoE was wrong to require trash-burning paperwork.

        I'm wondering if GPI could have avoided the problems by talking to the DoE more up front. One of the articles quoted a DoE representative as saying that the DoE had no idea what might come out of this plant, since nobody from GPI had filed any paperwork. But GPI filed paperwork with the EPA... are we to believe they withheld details of their process from the Washington state government but were willing to disclose the details to the EPA? If so, why?

        I can't sleuth out the truth by reading all the newspaper articles on the web, so I don't know for sure what exactly is going on. I just hope that they get this thing going... efficiently turning waste into usable fuel is a win every way you look at it.

        They claim they can produce diesel at a cost of less than $0.80 per gallon; at gas stations near me, diesel costs over four times that much, so they ought to be able to sell all the diesel they can make at a tidy profit. Then maybe they can pay back all the people to whom they owe money.

          I am a total skeptic of this plant, but good luck to him if it works.

          Reading through the stories, I see they are burning methane. And the process produces 10 tons of ash per 100 tons input, destined for cement kilns and the like. Will we get to know what is in that ash, or is it a 'trade secret?'

          So obviously there is some permitting process with the state he has to go through.

      Actually, I think they are referring primarily to plastics that get thrown in the trash. "Feedstock" is just a generic term for the raw material that goes into any type of factory. Since your laptop's outer shell is probably made of plastic, it could theoretically be used in this process. Busted laptops are e-waste (i.e. hazardous material), hence the special regulations that govern the disposal and recycling thereof. Considering this, I doubt that they could be used as raw feedstock for the fuel-creation process. However, after a bit of dismantling, the plastic bits could be separated from the rest and fed into this factory.

      Nevertheless, I agree that randomly claiming that 1 laptop == 1 quart of diesel fuel is just plain silly...

      Now your laptop can turn into a quart of diesel fuel to power your trip to the dump.

        I am aware of this, and mentioned myself that in this context it referred basically to organics. I did say "natural", which is not strictly accurate, but that is what these plants are typically tuned to consume. The thermal-reactor plant near the Tyson chicken factory, for example, can process just about any kind of organics from chicken parts to grain to cornstalks... and I imagine plastics too; they have been mentioned before.

    This sounds very similar to a heavy oil conversion unit, which takes long chains of hydrocarbons (organic materials) and breaks them into smaller molecules. Refineries have been doing this for decades! I'm not saying this isn't good to reduce overall waste or anything like that, but unless I'm missing something, this is hardly new technology...

    As a couple examples of conversion units:

    • Not all organic materials are hydrocarbons (exclusively hydrogen and carbon atoms). Cellulose, for example is chains of sugar (contain oxygen besides the hydrogen and carbon). Plenty of plastics are not hydrocarbons either.
      • True, I was focusing on hydrocarbons because that's what this technology is usually applied for. But the basic process of taking a long molecular chain and breaking it into multiple smaller chains seems pretty similar to what is done on hydrocarbons, even if the chain contains oxygen as well.
