Abstract

A waste processing system and method is described. The waste processing system may be used to treat any type of waste material that may be decomposed upon the application of energy, wherein recyclable metal and/or a gaseous end product is/are generated which may have commercial or industrial applications. The waste material may be reduced in size and passed to a purge vessel where the oxygen content of the waste material is reduced. The waste material is then heated in a heat exchanger which may be linearly elongated and passed to a conversion chamber where it is treated with H—H—O gas torches. A final gaseous end product is generated which may be used as a fuel source.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for processing waste, comprising:
 reducing dimensions of a quantity of waste material;   passing the reduced dimension waste material to a purge chamber;   reducing the quantity of oxygen in the purge chamber;   passing the oxygen free reduced dimension waste material from the purge chamber through a heat exchanger;   heating the oxygen free reduced dimension waste material in the heat exchanger;   passing the heated oxygen free reduced dimension waste material from the heat exchanger to a conversion chamber;   heating the oxygen free reduced dimension waste material in the conversion chamber using at least one H—H—O gas torch to generate at least a gaseous product;   passing the gaseous product through a heat exchanger to cool the gaseous product; and   harnessing the gaseous product.   
     
     
         2 . The method according to  claim 1 , further comprising removing recyclable metal materials from the quantity of waste material. 
     
     
         3 . The method according to  claim 2 , wherein removing recyclable metal materials from the quantity of waste material comprises removing at least a magnetic metal or a non-ferrous metal. 
     
     
         4 . The method according to  claim 1 , wherein harnessing the gaseous product comprises passing the gaseous product to a gas storage container. 
     
     
         5 . The method according to  claim 4 , wherein the gaseous product is passed through a second heat exchanger to further cool the gaseous product before harnessing. 
     
     
         6 . The method according to  claim 5 , wherein the gaseous product is passed through a particulate filter before harnessing. 
     
     
         7 . The method according to  claim 5 , wherein the gaseous product is passed through a water/NaOH bath before harnessing. 
     
     
         8 . The method according to  claim 5 , wherein the gaseous product is passed through an activated carbon filter before harnessing.
