K-listed waste
Spent lining from pots used to make primary aluminum

Industry: Primary aluminum.

Toxic K-listed waste from primary aluminum smelters. Spent potliners, the carbon linings of aluminum reduction pots.

Is K088 hazardous waste?

Yes. K088 is nonacute K-listed hazardous waste when the waste comes from the named process and matches the named stream. The federal table gives it hazard code (T), toxicity.

A K listing depends on where and how the waste was made, not on a test result alone. A test may add a characteristic code, but it doesn't remove the listing.

On a required hazardous waste manifest, put K088 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K088 cover?

Spent potliners from primary aluminum reduction. The waste form and the exact source process must both match. Chemical content alone is not enough.

Hazard code: (T), toxicity

Is primary aluminum spent potliner always K088?

Code	When it fits
K088	Spent potliners from primary aluminum reduction.

The industry, production step and waste form tell these K listings apart, not the chemicals in the waste. The rows above are only the nearby listed streams, so also add any characteristic or other listing that fits. One waste can carry more than one federal code.

What makes K088 source-specific?

K088 covers only the named waste form from the named primary aluminum operation. Other wastes from that industry need their own listing check, and an unlisted waste must still be checked for hazardous characteristics.

Which codes sit beside K088?

K084	Wastewater sludge from making arsenic-based veterinary drugs
