DESTRUCTION OF MACROMOLECULAR WASTE

The macromolecular waste (which is not itself susceptible to microwave heating and may be, for example, plastics or polychlorinated biphenyl) is mixed (B) with pulverulent carbonaceous material, which comprises elemental carbon or is degradable by microwave irradiation to elemental carbon (such as w...

Beschreibung
Zusammenfassung:	The macromolecular waste (which is not itself susceptible to microwave heating and may be, for example, plastics or polychlorinated biphenyl) is mixed (B) with pulverulent carbonaceous material, which comprises elemental carbon or is degradable by microwave irradiation to elemental carbon (such as waste tire material). The mix is subjected to microwave irradiation (C) in an inert atmosphere to cause pyrolysis of the plastics. Preferably part of the resulting solids is recycled to the microwave zone (C).
