Spent Material Law and Legal Definition
A "spent material" means "any material that has been used and as a result of contamination can no longer serve the purpose for which it was produced without processing. A spent material is one sort of secondary material when it is recycled, used in a manner constituting disposal, or used to produce products that are applied to or placed on the land or otherwise contained in products that are applied to or placed on land." Howmet Corp. v. United States EPA, 2009 U.S. Dist. LEXIS 87175 (D.D.C. Sept. 23, 2009)
