Classification

See the full D list

Wastes that are hazardous because of what they do, not where they come from: ignitability (D001), corrosivity (D002), reactivity (D003), or toxicity (D004-D043, defined by TCLP contaminant thresholds). Any industrial waste stream can carry a D code.

How D011 is handled

01

A D code is determined by testing, not by source: TCLP for toxicity (D004-D043), flash point for ignitability (D001), pH for corrosivity (D002).

02

Characteristic wastes can exit hazardous status when the characteristic is removed - treatment to below the regulatory level is a recognized compliance path.

03

Generators must count D-coded streams toward their monthly generator status (VSQG / SQG / LQG).

Where can a D011 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.

Precious metal recovery

High recovery

Silver-bearing wastes qualify for the reduced-burden precious metal recovery regime — photographic and plating silver streams are routinely refined back to metal.

40 CFR Part 266 Subpart F — precious metal recovery

Metals recovery (HTMR / hydrometallurgical)

Medium recovery

Metal-bearing residues route to high temperature metals recovery or hydrometallurgical processing, where the contained metals are extracted and returned to commerce as secondary raw material.

40 CFR 268.42 Table 1 — HTMR technology standard

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