Method of disposing of organic and inorganic substances and a plant for carrying out the method

In a method of disposing of organic and inorganic substances, the substances are gasified and decomposed in and/or above a liquid bath of a metal alloy under negative pressure, off-gases forming are seized, collected and purified and separated. To prevent the formation of health-endangering emissions, such as dioxins and furans, and to recover pure starting materials for the production of organic substances, the substances are charged under negative pressure into an induction furnace containing a melt (18) of an iron alloy, in particular a steel melt, and are decomposed in the latter at liquid steel temperature, whereby the entry of gaseous O2 is avoided. This is also the case at the production of steel from scrap interspersed with organic substances. To recover pure starting materials from inorganic dusts, the latter are charged into a negative pressure induction furnace containing an iron melt together with suitable additives and are decomposed in that furnace at liquid steel temperature and are transferred to the starting materials.
