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.""
Finally, a use for all those AOL CDs!
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.
I've gotten my microwave at home to break my food back down into component carbons. Or at least something pretty similar to coal.

Powering the next generation with the accumulated shit of the previous one. Brilliant.
Good! they can start by zapping all that annoying hard plastic bubble packaging that every bleeding thing seems to come in now and is harder then hell to open without damaging the contents! What frigging idiot came up with that idea?!? If there isn't a hell, they should make one, and put idiots like that in it! I know...a prison...we'll strip them naked and make sure their cells are free of anything with sharp or pointed edges, and all their meals, toilet paper, soap etc will come wrapped in their diabolical inventions!
You're using her as bait, Master!
Was there ever a "trendy" form of cremation?
>> plastic... broken down into... combustible gas
Try feeding your dog a (small) Lego. It has the same effect. For almost a week.
This is true and people have been using animal fat as a fuel ever since they discovered fire. Exxon realized that 150,000 people already die each year from global warming and their bodies represent an untapped, carbon neutral fuel source. Check out the results at Vivoleum.com, and you to may want to be a candle or SUV fodder. Burn guilt free!

Water vapor would be a powerful greenhouse gas, if there weren't already so much of it there. Basically, our atmosphere has so much water vapor, that every frequency of IR that can be absorbed by it is already fully absorbed. So more water vapor won't make a difference. CO2 and CH4, on the other hand, are potent greenhouse gasses because not only do they absorb IR, but they're pretty scarce our atmosphere.
wonder if it could be used to convert coal to a liquid hydrocarbon--would make the US the new saudi arabia for oil considering our huge coal deposits.
your brain has absorbed most of the energy

True, but how is it enforced? Perhaps in the Netherlands, people can be trusted to just do it, but I'm not sure that would work here.
... well, you tell me which one people are going to do? (Hint, it's the one that's less work.) Hell, I know people who don't even recycle metals, because it's too much work to sort stuff into the bin that they're already given. Easier just to chuck it all in one bin and not think about it. And that's only two cans, one for all mixed recyclables and one for 'everything else.'
In fact, I'm pretty sure that in my municipality, it's technically illegal to throw out anything that's toxic into the regular trash, but there's no enforcement mechanism, and given a choice between taking that old NiCd phone battery or fluorescent light tube to the recycling center, and just putting it in the trash
I've heard anecdotally that in Japan, there are people who basically go through trash at transfer stations, and will hunt down (based on personally identifying information in the trash) those folks who don't sort their recyclables out and reprimand/embarrass them -- short of something vaguely creepy like that (and in the U.S., social ostracism and humiliation aren't going to work as punishments), I'm not sure any consumer-sorting programs are going to work.
Without draconian enforcement, I think the sorting has to be -- or at least has to be backed up by sorting -- done at the transfer station or dump.
From a different perspective, sorting garbage based on predetermined criteria seems to be like something that, once you get over the initial investment in the system that does it, is probably better done by one giant machine that sorts the garbage for 100,000 people, than each of those 100,000 people having to take a few minutes a day to think about it. From a purely economic perspective, the opportunity cost of everyone's time probably justifies an automatic sorter, and when you factor in the recovered value from the recyclables [1] and the possible "dump mining" aspects that it creates later, I'd think it would be a good investment.
[1] The value of the metal and Type 1 plastic, anyway; the higher-number plastics don't seem to be worth recycling right now, at least based on what I've read.

You see? You see? Your stupid minds! Stupid! Stupid!
Not surprised by this at all.

There are countless stories of ancient technology where enlightened beings create things or destroy them by utilising special harmonic vibrations.
We have pyramids and whole cities being constructed in the remote jungle covered mountains of Peru by a small number of 'dwarfs' who move massive blocks of granite around using a nothing but a 'chiming rod'. (Sound being a vibration in teh audible spectra).
We have the armies of King David knocking down the walls of Jericho by blowing specific notes on the sacred horn of destruction. (Sound again being a vibration in teh audible spectra).
We have ancient Indians flying around in Vimyana airships and laying waste to massed armies with blasts of specially coded light waves. (Light being a vibration in teh visible spectra).
From ancient Inuit culture, we have heroes who can 'hummm' inaudible songs to summon a great whale from beneath the ice caps of the frozen north, and command the whale to do their bidding. (Subtonal vibrations in teh sensory spectra)
We have the ancient Malinese who claim to have built a city UNDER THE OCEAN in a single day, by banging two large fish together. (A vibration in teh olafactory spectra perhaps ?)
And the ancient Australian aboriginies, where the rainbow serpent created the mountains and the rivers and then literally sang day and night and linear time into existence. (A vibration in teh temporal spectra ?).
So why should we be surprised that vibrations in teh Microwave spectra hold the power to perform the modern alchemical trick of turning old barbie dolls and art-deco floor coverings into diesel fuel ?
Thats hardly progress - I would be impressed if they came up with a giant titanium chiming wand that could remotely construct a magnificent city on the Moon in a couple of hours, or a 100 square mile flawless pyramid of solid ruby on the surface of Mars over the space of a long weekend
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?

These numbers are attributed to Jerry Meddick, director of business development at Global Resource Corporation. I'd guess mr. Meddick originally said to the reporter "running 20 pounds of ground-up tyres ... produces 1.2 gallons of diesel oil, 50 cubic feet of combustible gas, 2.2 lb of steel, and 7.5 lb of carbon black", using units he's familiar with.
Okay, a publication calling itself scientific is not going to publish figures in non-SI units. I appreciate the effort of conversion, but it's not much better to publish figures in "base 0.454", as it were. Reading in base 10, the above quote best represents (in a roundabout way) the steel yield of the machine: to get 1 kg of steel, put in 9.1 kg of ground-up tyres.
What if you want to express the total yield per unit of ground-up tyres? Use a unit amount or a power of 10 amount of tyres and calculate the rest from that:
For every 10 kilograms of ground-up tyres, the Hawk-10 produces 5 litres of diesel oil, 1.6 cubic metres of combustible gas, 1.1 kg of steel, and 3.7 kg of carbon black.
This is much easier to comprehend: if a ton (1000 kg) of ground-up tyres were delivered to a Hawk-10, it would produce approximately 500 litres of diesel oil, enough to run my 1999 Ford Focus on my 100 km per day commute 5 days a week for 20 weeks.
Now, where's that microwawe...?
Usage: km/h for speed (kilometers per hour); kph for very slow impulses (kilopond hours).
One of the great and wonderful things about English is that spelling reflects quite accurately the history of the word. Sure, there are some pronunciation ambiguities that are a little difficult to learn, but even ESL learners get over that hill remarkably quickly.
But with English -- unlike almost any other language -- you can look at a word and immediately know that its roots are in Greek, or Latin, or French, or Celtic, or whether it's a modern loan word. This has massive benefits for advanced literacy, as it means you actually know more words than you think you do, and can quite accurately guess at the meaning of new words you encounter -- which is of far greater utility than simply knowing how to say the word. Get the sound wrong and people will correct you almost immediately, so what's the problem?
In other languages, once a word has been imported, its roots are lost, and with that the connection to the linguistic system from which it came, and its connection to other similarly-sourced words.
So, regular spelling: great for primary school kids; not so great for everyone else who wants to use language at a more advanced level, for things like communication and literature.
How much microwave power do you need to reconstitute oil back into dinosaurs?

You can do more with oil than just burn it, such as turning it into plastic.
