RCRA Hazardous Waste Number
Corrosive waste - aqueous wastes with pH at or below 2 or at or above 12.5, or liquids that corrode steel faster than 6.35 mm per year

Need recovery options for a D002 stream?
Map recovery routes for D002Wastes 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).
Common industrial materials that can carry the D002 waste code — each finder page shows exactly when it applies.
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 acids and caustics are regeneration candidates: spent pickling and etching liquors can be processed for acid recovery or metal-salt by-products, depending on free-acid strength and dissolved metal load.
40 CFR 261.1(c)(4) — reclamationWastes hazardous only for corrosivity can be treated in an elementary neutralization unit — a recognized unit type that manages the characteristic without a full treatment permit.
40 CFR 260.10 — definitionsThese are the typical routes for the D list. Your stream's actual options depend on its composition and where it sits.

With a lab analysis, the engine checks the stream against each receiving route's published limits and returns what is supported, what is refused, and why. Without one yet, we tell you which routes it can evaluate and what analysis that needs.
