Industry: Organic chemicals.

Listed withK-listed waste

Toxic K-listed waste from organic chemical plants. Aqueous spent antimony catalyst from making fluoromethanes.

Is K021 hazardous waste?

Yes. K021 is nonacute hazardous waste when your waste comes from the named process and stream. The federal table gives it hazard code (T), for toxicity.

A K listing follows how and where the waste arose, not a concentration test. A test may add a characteristic code, but it doesn't remove this listing.

On a required hazardous waste manifest, put K021 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K021 cover?

This listing covers aqueous spent antimony catalyst waste from fluoromethanes production. The waste form and the source process must both match this listing. Chemical content alone isn't enough.

Is spent fluoromethanes antimony catalyst always K021?

CodeWhen it fits
K021It is aqueous spent antimony catalyst waste from fluoromethanes production.
K028It is spent catalyst from the hydrochlorinator reactor while producing 1,1,1-trichloroethane.
K013It is bottom stream from the acetonitrile column while producing acrylonitrile.

The industry, production step and waste form tell these K listings apart, not chemical content. The rows show nearby listed streams, not every code that could apply. Add any characteristic or other listing that also fits, because a waste can carry several federal codes.

Which codes sit beside K021?
