Abstract:
1. A method of processing multicomponent of composite and combined materials, the method comprising the steps of: mixing waste materials from electronic and electric devices and equipments, by using separated components, under the action of a moving bed of solid particles of a substance, yielding a mixture; performing whirling movement, characterized in that the treated materials are pretreated by removing contaminating components containing toxic heavy metals and polychlorinated biphenyls by grinding the waste to particles having the size of 5 to 25 mm; and subjecting the mixture in an inert environment at a temperature of 350° C. to 600° C. and at a pressure of 100 kPa to 10 MPa, to the action of blades of a rotational mechanism for 10 seconds to 10 minutes, wherein in the mixture occurs depolymerization, cracking and state transformation of macromolecular, solid and liquid organic fractions and their separation from the composite material in the form of organic vapors and gases, and disintegration of inorganic non-metallic fractions to small particles and increase of metal concentration in inorganic phase.
