Abstract: A method of processing polymer materials, highly filled or otherwise to recover cyclic structures or monomers. The method involves providing a vessel having a heated side wall, an agitator, and at least one of an additional heated structure, other than the heated side wall, within the vessel and means for forming a thin coat of material processed in the vessel on said heated side wall. A polymer material is fed into the vessel and heated to a sufficient temperature to cause depolymerization of the polymer material into cyclic structures or monomers. The cyclic structures or monomers are removed from the vessel and collected. The method does not require the use of a solvent.

Abstract: A method of using an induction furnace to process iron ore into an iron product such as pig iron in which iron ore is the main or exclusive source of iron fed into the induction furnace.

Abstract: A method of operating a channel induction furnace so as to receive electric arc furnace (EAF) dust, basic oxygen furnace (BOF) sludge/dust and/or other iron and volatile metals containing materials as a feed stream on a batch, continuous or semi-continuous basis together with a iron-containing material feed, and therefrom produce an iron-containing hot metal or pig iron product while recovering iron value from the feed materials and recovering volatile metal components contained in the feed materials.

Abstract: A method of recycling electronic waste and recovering valuable metal components from electronic waste which involves feeding electronic wastes such as cell phones, computers, pagers, personal data assistants, handheld global positioning devices, MP3 players, calculators, batteries, etc. into an induction furnace that is changed with a mass of liquid iron. A portion of organic components of the electronic waste can be removed prior to feeding the electronic waste into the induction furnace and/or volatilized or decomposed in the induction furnace. The metal components of the electronic waste form separate liquid layers in the induction furnace that are separated according to their densities. The separated metals layers are recovered either in a solid or liquid phase.
