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.
"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.
Gershow Recycling, a scrap metal company based in New York, US, has just said it will be the first to buy a Hawk-10. [...] 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.
