Giant Microwave Turns Plastic Back to Oil
An anonymous reader writes "From the newscientist article: "Key to GRC's process is a machine that uses 1200 different frequencies within the microwave range, which act on specific hydrocarbon materials. As the material is zapped at the appropriate wavelength, part of the hydrocarbons that make up the plastic and rubber in the material are broken down into diesel oil and combustible gas.""
That the mines of the next century will be our garbage mountains. It will be the place with the highest density of easily obtainable materials.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
no mention on how much energy it takes to run the thing, or how much energy it puts out. it's not of much use if it costs a fraction to just bury the old plastic and make new stuff from scratch.
Great.. and just when we were starting to look at alternative fuel
Just need to have non-stupid options. Every four or five months, I check with my state's waste management website for how to handle the tricky stuff (like fluorescent tubes and button batteries), mostly because that's about how often I lose a CFL. Their answer is that I must drive halfway across the state (it's a small state, but the way the roads are, half-way across might as well be all the way across). Also, I have to make a special appointment for the privilege.
I might consider doing this when my CRT monitor finally fails, but somehow I doubt that burning 12 gallons of gasoline for a single compact bulb is less harmful to the environment than tossing it in with the regular trash. And if it's not, then there's no point in my continuing to use them, as the 12 gallons of gasoline puts the lifetime cost well over that which regular light bulbs would've been over the same time period. They fail to break often enough that just accumulating a bunch of spent CFLs is really an option. It'd take me ten years to fill a small box with 'em, and frankly, I don't want to store hazardous waste for that long.
The items aren't exactly very large or numerous. I fail to see why they can't just put one or more small bins at the transfer station for them. How much space would a whole town's worth of expired button batteries need to take, anyway?

That had to be the worst anti-recycling link I've ever read. Heck, Penn and Teller even did a better job. Many Items are profitable to recycle, hence the existence of private scrap yards. Some consumer waste 'is' profitable, but since the US local governments decide to do curbside pickup, it no longer saves energy. They solved this problem in Vienna by having neighborhood bins. The trucks only come when the bin is full. A simple idea like that turned glass and metal (including aluminum) profitable. Granted, the profit goes to subsidize the plastic recycling, which needs local compactors to break even.
Corporate recycling (bottles from bars that go back to the bottler, unsold newspaper pickup, etc, are all private and profitable.
In conclusion, recycling consumer waste 'can' be profitable, and the low hanging fruit already is profitable. It's just that our governing bodys (that control recycling) are too dumb and wasteful to figure it out.

No, the reason why plastics are not very recyclable is that you cannot substitute one plastic for another. The previous method recycles polycarbonate from CDs only into polycarbonate. Polycarbonate cannot be used instead of polyethylene, polypropylene, polyvinyl chloride, etc. These other plastics have far more uses. So turning into fuel is a more general use to me.
Well, there's spam egg sausage and spam, that's not got much spam in it.
What's neat about this is that it takes waste products that would end up in a land fill and converts them to a usable form again... with a surplus over the amount of energy needed to do so. Not much, certainly not enough to supplant alternative fuel sources... but enough to drive the conversion process and power a few other machines nearby.
This will be great for factories all around and farms and other types of businesses that end up with a lot of waste material. Maybe we can make those 75% self-sustaining... which means they won't be depleting more raw materials as quickly. This is a good thing.
Even if the only use is for our Municipal trash companies to run their fleet of vehicles off of the trash they collect... we've won a huge gain. Maybe trucking companies could do the same... converting their used tires to fuel every month (they go through a lot of tires).
This is equivalent to farms using their biomass to convert to biodiesel or ethanol for use in their farm equipment. It's not a commercial enterprise but it reduces waste and improves their efficiency which means they can pass the savings on to the rest of us (or stop needing subsidies from tax dollars).
A fool throws a stone into a well and a thousand sages can not remove it.
Not ideal, to be sure. And it IS what their first customer appears to be doing. Still, this is better than burying the plastic in a landfill and pumping more oil out of the ground to be burned. I guess baby steps are better than no steps at all.
