Classification

See the full F list

Manufacturing process wastes that arise across many industries: spent solvents (F001-F005), electroplating and metal finishing wastes (F006-F019), and others. The code follows the process, not the industry.

How F039 is handled

01

F-listed wastes carry the code from the process that produced them, in any industry.

02

The mixture rule applies: mixing an F-listed waste into another stream generally makes the whole stream F-listed.

03

Spent solvent F codes (F001-F005) are among the most commonly recycled RCRA streams - solvent recovery and fuel blending are established routes.

Other F-list codes

F001The following spent halogenated solvents used in degreasing: Tetrachloroethylene, trichloroethylene, methylene chloride, 1,1,1-trichloroethane, carbon tetrachloride, and chlorinated fluorocarbons; all spent solvent mixtures/blends used in degreasing containing, before use, a total of ten percent or more (by volume) of one or more of the above halogenated solvents or those solvents listed in F002, F004, and F005; and still bottoms from the recovery of these spent solvents and spent solvent mixturesF002The following spent halogenated solvents: Tetrachloroethylene, methylene chloride, trichloroethylene, 1,1,1-trichloroethane, chlorobenzene, 1,1,2-trichloro-1,2,2-trifluoroethane, ortho-dichlorobenzene, trichlorofluoromethane, and 1,1,2-trichloroethane; all spent solvent mixtures/blends containing, before use, a total of ten percent or more (by volume) of one or more of the above halogenated solvents or those listed in F001, F004, or F005; and still bottoms from the recovery of these spent solvents and spent solvent mixturesF003The following spent non-halogenated solvents: Xylene, acetone, ethyl acetate, ethyl benzene, ethyl ether, methyl isobutyl ketone, n-butyl alcohol, cyclohexanone, and methanol; all spent solvent mixtures/blends containing, before use, only the above spent non-halogenated solvents; and all spent solvent mixtures/blends containing, before use, one or more of the above non-halogenated solvents, and, a total of ten percent or more (by volume) of one or more of those solvents listed in F001, F002, F004, and F005; and still bottoms from the recovery of these spent solvents and spent solvent mixturesF004The following spent non-halogenated solvents: Cresols and cresylic acid, and nitrobenzene; all spent solvent mixtures/blends containing, before use, a total of ten percent or more (by volume) of one or more of the above non-halogenated solvents or those solvents listed in F001, F002, and F005; and still bottoms from the recovery of these spent solvents and spent solvent mixturesF005The following spent non-halogenated solvents: Toluene, methyl ethyl ketone, carbon disulfide, isobutanol, pyridine, benzene, 2-ethoxyethanol, and 2-nitropropane; all spent solvent mixtures/blends containing, before use, a total of ten percent or more (by volume) of one or more of the above non-halogenated solvents or those solvents listed in F001, F002, or F004; and still bottoms from the recovery of these spent solvents and spent solvent mixturesF006Wastewater treatment sludges from electroplating operations except from the following processes: (1) Sulfuric acid anodizing of aluminum; (2) tin plating on carbon steel; (3) zinc plating (segregated basis) on carbon steel; (4) aluminum or zinc-aluminum plating on carbon steel; (5) cleaning/stripping associated with tin, zinc and aluminum plating on carbon steel; and (6) chemical etching and milling of aluminumF007Spent cyanide plating bath solutions from electroplating operationsF008Plating bath residues from the bottom of plating baths from electroplating operations where cyanides are used in the process

Where can a F039 stream go?

Recognized recovery routes for this waste family, ranked by typical recovery tier. Which route fits depends on your specific stream — composition, volume and region.

Wastewater treatment & water reuse

Low recovery

Multi-source leachate is a high-volume, low-concentration stream: recovery is limited to treated-water reuse; the concentrated residue follows the land disposal restriction standards.

40 CFR 268.40 — LDR treatment standards

Specialist constituent review

Specialist handling

Leachate quality varies by source cell; a constituent-level review can reveal recoverable fractions or cheaper compliant treatment trains than the default assumption.

40 CFR 261.1(c)(4) — reclamation

These are the typical routes for the F list. Your stream's actual options depend on its composition and where it sits.

Leachate (liquids that have percolated through land disposed wastes) resulting from the disposal of more than one restricted waste classified as hazardous under subpart D of this part. (Leachate resulting from the disposal of one or more of the following EPA Hazardous Wastes and no other Hazardous Wastes retains its EPA Hazardous Waste Number(s): F020, F021, F022, F026, F027, and/or F028.)

With a lab analysis, the engine checks the stream against each receiving route's published limits and returns what is supported, what is refused, and why. Without one yet, we tell you which routes it can evaluate and what analysis that needs.

What do you need?

An engineer replies within 1 business day. That reply confirms what is needed to run the dossier and when it can follow. A route the engine does not cover yet is reported as not yet evaluable, with the evidence that would change that.
