Giant microwave turns plastic back to oil
A US company is taking plastics recycling to another level – turning them back into the oil they were made from, and gas.

All that is needed, claims Global Resource Corporation (GRC), is a finely tuned microwave and – hey presto! – a mix of materials that were made from oil can be reduced back to oil and combustible gas (and a few leftovers).

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.

GRC's machine is called the Hawk-10. Its smaller incarnations look just like an industrial microwave with bits of machinery attached to it. Larger versions resemble a concrete mixer.

"Anything that has a hydrocarbon base will be affected by our process," says Jerry Meddick, director of business development at GRC, based in New Jersey. "We release those hydrocarbon molecules from the material and it then becomes gas and oil."

Whatever does not have a hydrocarbon base is left behind, minus any water it contained as this gets evaporated in the microwave.

Simplified recycling

"Take a piece of copper wiring," says Meddick. "It is encased in plastic – a kind of hydrocarbon material. We release all the hydrocarbons, which strips the casing off the wire." Not only does the process produce fuel in the form of oil and gas, it also makes it easier to extract the copper wire for recycling.

Similarly, running 9.1 kilograms of ground-up tyres through the Hawk-10 produces 4.54 litres of diesel oil, 1.42 cubic metres of combustible gas, 1 kg of steel and 3.40 kg of carbon black, Meddick says.

Watch a video of tyre powder being reduced by the Hawk-10.

Less landfill

Gershow Recycling, a scrap metal company based in New York, US, has just said it will be the first to buy a Hawk-10. Gershow collects metal products, shreds them and turns them into usable pure metals. Most of its scrap comes from old cars, but for every ton of steel that the company recovers, between 226 kg and 318 kg of "autofluff" is produced.

Autofluff is the stuff that is left over after a car has been shredded and the steel extracted. It contains plastics, rubber, wood, paper, fabrics, glass, sand, dirt, and various bits of metal. GRC says its Hawk-10 can extract enough oil and gas from the left-over fluff to run the Hawk-10 itself and a number of other machines used by Gershow.

Because it makes extracting reusable metal more efficient and evaporates water from autofluff, the Hawk-10 should also reduce the amount of end material that needs to be deposited in landfill sites.

The crisis of modern democracy is a profound one. Free elections, a free press and an independent judiciary mean little when the free market has reduced them to commodities available on sale to the highest bidder.

The era of manufacturing consent has given way to the era of manufacturing news. Soon media newsrooms will drop the pretense, and start hiring theater directors instead of journalists.

The structure of capitalism is flawed. The motor that powers it cannot but vastly increase the disparity between the poor and the rich globally and within countries as well. Parecon is a brave argument for replacing that flawed machine and offers a much needed -- more equitable, democratic, participatory -- alternative economic vision.
