(a) For the purposes of the definition of "Solid waste" in §335.1 of this title (relating to Definitions) and §335.24 of this title (relating to Requirements for Recyclable Materials and Nonhazardous Recyclable Materials):
  (1) A spent material is 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.
  (2) Sludge has the same meaning used in Texas Health and Safety Code, §361.003.
  (3) A by-product is a material that is not one of the primary products of a production process and is not solely or separately produced by the production process. Examples are process residues such as slags or distillation column bottoms. The term does not include a co-product that is produced for the general public's use and is ordinarily used in the form in which it is produced by the process.
  (4) A material is reclaimed if it is processed to recover a usable product, or if it is regenerated. Examples are recovery of lead values from spent batteries and regeneration of spent solvents. For purposes of 40 Code of Federal Regulations (CFR) §261.4(a)(23) and (24), smelting, melting, and refining furnaces are considered to be solely engaged in metals reclamation if the metal recovery from the hazardous secondary materials meets the same requirements as those specified for metals recovery from hazardous waste found in §335.221(a)(1) of this title (relating to Applicability and Standards), and if the residuals meet the requirements specified in §335.221(a)(23) of this title.
  (5) A material is used or reused if it is either:
    (A) employed as an ingredient (including use as an intermediate) in an industrial process to make a product (for example, distillation bottoms from one process used as feedstock in another process). However, a material will not satisfy this condition if distinct components of the material are recovered as separate end products (as when metals are recovered from metal-containing secondary materials); or
    (B) employed in a particular function or application as an effective substitute for a commercial product (for example, spent pickle liquor used as phosphorous precipitant and sludge conditioner in wastewater treatment).
  (6) Scrap metal is bits and pieces of metal parts (e.g., bars, turnings, rods, sheets, wires) or metal pieces that may be combined together with bolts or soldering (e.g., radiators, scrap automobiles, railroad box cars), which when worn or superfluous can be recycled.
  (7) A material is recycled if it is used, reused, or reclaimed.
  (8) A material is accumulated speculatively if it is accumulated before being recycled. A material is not accumulated speculatively, however, if the person accumulating it can show that the material is potentially recyclable and has a feasible means of being recycled; and that, during the calendar year (commencing on January 1), the amount of material that is recycled, or transferred to a different site for recycling, equals at least 75% by weight or volume of the amount of that material accumulated at the beginning of the period. Materials must be placed in a storage unit with a label indicating the first date that the material began to be accumulated. If placing a label on the storage unit is not practicable, the accumulation period must be documented through an inventory log or other appropriate method. In calculating the percentage of turnover, the 75% requirement is to be applied to each material of the same type (e.g., slags from a single smelting process) that is recycled in the same way (i.e., from which the same material is recovered or that is used in the same way). Materials accumulating in units that would be exempt from regulation under 40 CFR §261.4(c) are not to be included in making the calculation. (Materials that are already defined as solid wastes also are not to be included in making the calculation.) Materials are no longer in this category once they are removed from accumulation for recycling, however.
  (9) Excluded scrap metal is processed scrap metal, unprocessed home scrap metal, and unprocessed prompt scrap metal.
  (10) Processed scrap metal is scrap metal which has been manually or physically altered to either separate it into distinct materials to enhance economic value or to improve the handling of materials. Processed scrap metal includes, but is not limited to, scrap metal which has been baled, shredded, sheared, chopped, crushed, flattened, cut, melted, or separated by metal type (i.e., sorted), and, fines, drosses and related materials which have been agglomerated. (Note: shredded circuit boards being sent for recycling are not considered processed scrap metal. They are covered under the exclusion from the definition of solid waste for shredded circuit boards being recycled (40 CFR §261.4(a)(14)).
  (11) Home scrap metal is scrap metal as generated by steel mills, foundries, and refineries such as turnings, cuttings, punchings, and borings.
  (12) Prompt scrap metal is scrap metal as generated by the metal working/fabrication industries and includes such scrap metal as turnings, cuttings, punchings, and borings. Prompt scrap is also known as industrial or new scrap metal.
