Industrial Waste.




  • Types of industrial waste required as materials for industrial use include:
    • Waste wood
    • Waste thermoplastics; but not including thermoplastic medical waste
    • Waste paper
    • Waste steel (including stainless steel)
    • Waste metals of a single kind (copper, zinc, iron, aluminum, tin, titanium, silver, magnesium, germanium, nickel, or tungsten) meeting the following conditions:
      1. Do not contain mercury.
      2. Are metallic in nature (such as a metal, alloy, or electroplating metal).
      3. Do not include powder, sludge, ash, or harmful liquid waste.
      4. Chief metal content is 40% or greater.
    • Waste copper fragments meeting the following conditions:
      1. The copper fragments are derived from the bare copper wire production process.
      2. Are metallic in nature.
      3. Do not contain oil or grease.
      4. The copper content is 40% or greater.
    • Waste zinc dross meeting the following conditions:
      1. The zinc dross or skimmings are derived from electroplated sheet surface and base, die-casting, or hot dip electroplating sheet processes.
      2. The zinc content is 40% or greater.
      3. Leaching of hazardous substances must be less than the leaching standards in Attached Table 4 Standards for Defining Hazardous Industrial Waste, Toxic Characteristic Leaching Procedure (TCLP).
    • Waste iron slag meeting the following conditions:
      1. The iron slag is derived from the copper refining process (rich iron oxide).
      2. It may only be imported or used by the cement manufacturing industry when imported.
      3. Leaching of hazardous substances must be less than the leaching standards in Attached Table 4 Standards for Defining Hazardous Industrial Waste, Toxic Characteristic Leaching Procedure (TCLP).
    • Waste magnesium dross meeting the following conditions:
      1. The magnesium dross or sediment is derived from casting and machinery use processes.
      2. The magnesium content is 40% or greater.
      3. Leaching of hazardous substances must be less than the leaching standards in Attached Table 4 Standards for Defining Hazardous Industrial Waste, Toxic Characteristic Leaching Procedure (TCLP).
    • Waste catalyst meeting the following conditions:
      1. Is derived from processes in the petrochemical raw material manufacturing and petroleum refining industries or used in motor vehicle catalytic converters.
      2. Contains noble metals (gold, silver, platinum, palladium, iridium, rhodium, osmium, ruthenium), transition metals (vanadium, cobalt, nickel, copper, zinc, molybdenum), or zeolite catalyst.
      3. Is not waste catalyst derived from heavy fuel oil hydrogenation and desulfurization processes.
    • Waste rubber: Does not consist of waste tires or processed waste tire flakes greater than 4 mm in diameter.
    • Fiberglass cloth edge cuttings and scrap; but not containing fiberglass debris or powder
    • Mixed aluminum and copper waste: Meaning auto and motorcycle water tanks and household appliance radiators (panels)
    • Waste silicon (pieces, rods, wafers, chips, or crucible waste) meeting the following conditions:
      1. Is derived from the integrated circuit manufacturing industry or other optoelectronic material or component manufacturing industry.
      2. The silicon content is 90% or greater.
      3. Leaching of hazardous substances must be less than the leaching standards in Attached Table 4 Standards for Defining Hazardous Industrial Waste, Toxic Characteristic Leaching Procedure (TCLP).
    • Chaff, bran, or residue of maize, rice, wheat, or other cereal
    • Residue from legumes or starchy products, and similar residues
    • Beet pulp, soybean cake
    • Other solid residues (including oil cake) resulting from the refining of soybean oil or peanut oil
    • Oil cake and solid residue from cotton seed, flax seed, sunflower seed, rape seed, coconut and copra, palm nuts and seeds, and maize germ
