RCRA Hazardous Waste Number
The 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 mixtures

Need recovery options for a F004 stream?
Map recovery routes for F004Manufacturing 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.
F-listed wastes carry the code from the process that produced them, in any industry.
The mixture rule applies: mixing an F-listed waste into another stream generally makes the whole stream F-listed.
Spent solvent F codes (F001-F005) are among the most commonly recycled RCRA streams - solvent recovery and fuel blending are established routes.
Recognized recovery routes for this waste family, ranked by typical recovery tier. Which route fits depends on your specific stream — composition, volume and region.
Spent solvents are among the most recycled RCRA streams: distillation recovers a technical-grade solvent for reuse, with only the still bottoms remaining as waste.
40 CFR 261.1(c)(4) — reclamationSolvent reclaimed in an enclosed, hard-piped loop back into the generating process can be excluded from waste regulation entirely — the strongest position a solvent stream can be in.
40 CFR 261.4(a)(8) — closed-loop reclamation exclusionDistillation residues and unrecoverable solvent fractions retain fuel value and route to fuel blending for energy recovery in permitted industrial furnaces.
40 CFR Part 266 Subpart H — burning for energy recoveryThese are the typical routes for the F list. Your stream's actual options depend on its composition and where it sits.
