The present invention relates to a method for disposing electrical and electronic equipment comprising plastic and metal components, the method comprising: melt processing the equipment and/or comminuted parts thereof to form a melt processed product; transferring the melt processed product into a vessel and heating the product using far infrared radiation such that it liberates volatile hydrocarbons and leaves behind non-volatile residue comprising metal; and collecting one or both of the volatile hydrocarbons and the non-volatile residue for subsequent use.

La présente invention porte sur un procédé pour la destruction d'un appareillage électrique et électronique renfermant des composants en matière plastique et en métal, le procédé comprenant : le traitement en phase fondue de l'appareillage, et/ou de parties fragmentées de celui-ci, pour former un produit traité en phase fondue ; le transfert du produit traité en phase fondue dans une cuve et le chauffage du produit à l'aide d'un rayonnement infrarouge lointain de façon à ce qu'il libère des hydrocarbures volatils et à ce qu'il laisse un résidu non volatil renfermant du métal ; et la collecte de l'un parmi les hydrocarbures volatils et le résidu non volatil ou des deux pour une utilisation ultérieure.
