Are spent catalysts always hazardous?

Not always. Spent precious metal catalysts (16 08 01) are non-hazardous. Catalysts containing heavy metals, sulfides, or pyrophoric materials (16 08 07*) are hazardous and require manifested handling.

How is PGM value determined at handover?

PGM-bearing catalysts are assayed by the receiver. The contract typically specifies a sampling method (ASTM E2863 or equivalent), assay method, and settlement terms based on LME fix prices at the time of refining.

Can spent halogenated solvents be reclaimed?

Yes — halogenated solvents (07 01 03*) can be re-distilled to recoverable quality. Grade and economics depend on contamination level. SymbioFlows will assess your stream against current re-distiller acceptance specs.
