Pigments, solvents, packaging and by-products are the obvious streams. In practice one stream dominates the disposal bill: the washings from cleaning tanks, mills and lines between batches. Whether those washings are an F-listed hazardous waste or an ignitable one turns on a distinction that is easy to state and easy to get wrong.
The F001 to F005 listings cover spent solvents used for their solvent properties — to dissolve, to degrease, to clean. A solvent that went into a formulation as an ingredient was not used as a solvent, so the residue of that batch is not F-listed on those grounds, though it may still be ignitable or toxic on its own merits. The same drum of the same chemical can therefore be a listed waste in one line and a characteristic waste in another, with different treatment standards and different cost. On a plant that both formulates with solvent and cleans with it, this is the question that decides the profile, and it has to be answered per stream rather than per site.
What a coatings operation sends off site, what each stream is under the federal rules, and the service that takes it — with the codes as a starting point for a profile rather than a substitute for one.
F003 / F005 / D001
The largest routine stream. Listed when the solvent was used for cleaning; ignitable in most cases either way. The answer to the listing question changes the treatment standard.
Hazardous Waste IncinerationD001 / D007 / D008
Product that missed specification or came back. Ignitable from the solvent carrier, and sometimes toxic from chromium or lead in the pigment, depending on the formulation's age and market.
Off-Spec Product DisposalD007 / D008
Bag filters, cartridges and settled pigment. Heavy-metal pigments put these over the toxicity characteristic even when the parent product did not.
RCRA Hazardous Waste DisposalDepends on the feed
From treating waterborne line washings. If any listed waste reaches the treatment system, the mixture and derived-from rules follow it into the sludge.
Industrial Wastewater TreatmentRCRA-empty or not
A container is only exempt once it meets the regulatory definition of empty. Part-full drums of finished product are not scrap metal, and they are a common finding on inspection.
Non-Acute Hazardous Waste DisposalRecovery candidate
Cleaning solvent with a consistent composition is often worth distilling rather than burning. Fuels blending is the alternative route when recovery is not economic.
Fuels Blending ServicesThe parts of the federal rules that decide how a coatings generator is treated — and the ones that catch this industry specifically rather than every industry equally.
Mix a listed waste with anything else and the whole mixture generally carries the listing. On a plant with shared drains and a common treatment system, that decides far more than the volume of the original stream.
A D001 stream brings separation distances, ignition-source control and container standards with it. On a solvent plant these apply to the accumulation area as much as to production.
A container holding a non-acute hazardous waste is regulatorily empty only when the material has been removed by the normal means and no more than a small defined residue remains. Containers that held acutely hazardous waste have a far stricter test.
Not the whole catalog — the ones a coatings site actually meets, in roughly the order it meets them.
What coatings generators ask before they ask for a price, answered from the rules rather than from marketing copy.
It depends on whether the solvent was used for its solvent properties, and on whether it is one of the chemicals actually named in the listings. Cleaning a tank is solvent use; being an ingredient in the coating is not. A profile answers it per stream, and the answer changes the treatment standard, so it is worth settling rather than assuming the conservative case forever.
Often, when the composition is consistent enough to distil. Where recovery is not economic, fuels blending recovers the energy value instead. Both are better answers than incineration for a stream that is clean enough, and which applies is a question about your washings rather than about the market.
Yes, and mostly in the filter media and settled residues rather than in the finished product. Where those pigments are or were in use, the toxicity characteristic is worth testing for specifically rather than assuming the solvent is the only issue.
