Classification

See the full K list

Source-specific wastes from 13 named industries, including petroleum refining, wood preservation, pesticide manufacturing and iron and steel production. Each K code names both the industry and the exact process residue.

How K061 is handled

01

K codes apply only to the named industry and the named process residue.

02

Many K wastes have established recovery paths inside their industry (e.g. metals reclamation from refinery and steel residues).

03

Land disposal restrictions (40 CFR Part 268) set treatment standards before disposal.

Where can a K061 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.

High temperature metals recovery

Medium recovery

Metal-bearing industry residues — furnace dusts, pickle liquors, smelting residues — route to high temperature metals recovery, where zinc, lead and other metals return to commerce.

40 CFR 268.42 Table 1 — HTMR technology standard

In-process reclamation

Medium recovery

Process residues that still carry recoverable product or feedstock value can be reclaimed — processed to recover a usable material or regenerated for reuse — inside or outside the generating industry.

40 CFR 261.1(c)(4) — reclamation

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 K list. Your stream's actual options depend on its composition and where it sits.
