Abstract: Pyrolysis system and method wherein used batteries other than lead-acid batteries for reclamation and recovery of the constituents therein or environmentally safe disposal are placed in rail carts and moved on rails through an entry zone into a central heating zone of a pyrolysis chamber maintained under a negative pressure and then into an exit zone.

Abstract: Used batteries and other material for reclamation and recovery or environmentally safe disposal are transferred from a feed bin by an auger into a crusher and then into a pyrolysis chamber. The feed system excludes air or oxygen from passing through the auger and crusher into the pyrolysis chamber. The material from the crusher is transferred by an auger through the pyrolysis chamber which is heated to a decomposition temperature between 350.degree. and 650.degree. F. and is decomposed. The pyrolysis chamber includes a vapor recovery system for removing the vapors and maintaining a vacuum in the pyrolysis chamber. The vapors are withdrawn through a heat exchanger and into the liquid/gas separator where the condensed liquids are removed and the gas is further processed. The residue from the pyrolysis chamber is discharged into a residue recovery system which includes a closed auger for transferring the residue from the pyrolysis chamber into a bin.
