RCRA Hazardous Waste Number

F035

Wastewaters (except those that have not come into contact with process contaminants), process residuals, preservative drippage, and spent formulations from wood preserving processes generated at plants that use inorganic preservatives containing arsenic or chromium. This listing does not include K001 bottom sediment sludge from the treatment of wastewater from wood preserving processes that use creosote and/or pentachlorophenol

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 F035 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.

EU equivalent codes

European Waste Catalogue (EWC) codes that describe an overlapping or equivalent waste stream to F035.

EWC 03 02 04overlaps

F035 covers wastes from wood-preserving processes that use inorganic arsenic or chromium preservatives (e.g. CCA); EWC 03 02 04 is the matching wood-preservation waste code for inorganic preservatives — the difference is RCRA's process basis vs EWC's preservative-chemistry basis.

Where can a F035 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.

Preservative recovery & reuse in-process

Medium recovery

Wood-preserving process residues can be reclaimed for preservative recovery back into the treating process where formulation and contamination allow.

40 CFR 261.1(c)(4) — reclamation

Fuel blending & energy recovery

Medium recovery

Organic-bearing streams with usable fuel value can be blended and burned for energy recovery in permitted boilers and industrial furnaces instead of being incinerated as pure disposal.

40 CFR Part 266 Subpart H — burning for energy recovery

Stabilization & controlled disposal

Low recovery

Below economic metal concentrations, stabilization to the land disposal restriction treatment standard followed by controlled disposal remains the default management route.

40 CFR 268.40 — LDR treatment standards

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