ABSTRACT:
The present invention advantageously uses a composition which includes iron-containing waste materials to dispose of the toxic and troublesome substances, polybrominated biphenyls (PBB). First, waste materials from the conversion of iron ore to pig iron or steel combine with a reducing metal, such as aluminum or magnesium, and a small portion of a mineral acid to form a reaction mixture which gives a heat output superior to many conventional fuels and at a very high temperature. Then, this composition is heated to a reaction temperature with pure PBB or items contaminated with PBB to thereby chemically break down the PBB.
