Need recovery options for a D005 stream?
Map recovery routes for D005Wastes 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.
A D code is determined by testing, not by source: TCLP for toxicity (D004-D043), flash point for ignitability (D001), pH for corrosivity (D002).
Characteristic wastes can exit hazardous status when the characteristic is removed - treatment to below the regulatory level is a recognized compliance path.
Generators must count D-coded streams toward their monthly generator status (VSQG / SQG / LQG).
Recognized recovery routes for this waste family, ranked by typical recovery tier. Which route fits depends on your specific stream — composition, volume and region.
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 standardBelow 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 standardsThese are the typical routes for the D list. Your stream's actual options depend on its composition and where it sits.
