I wonder if anyone has looked into the disposal of fiber dyes used in student activities events?
The particular brand I'm interested in is from Dharma Trading Company and their SDS's are remarkably uninformative. The SDSs states
Waste Disposal Methods: Should not be released into the environment. Dispose of in accordance with local regulations. This material, as supplied, is not a hazardous waste according to state and federal regulations (40 CFR 261).
The local sewage authority would like to know if there are metals in the dyes, but the company representative only knows what's on the SDS that came with the powder they bought from their supplier, so I would like to have a source of corroborative information for the SDS before I respond to the city. Any suggestions for other sources of information would be appreciated.
Thanks for any information on this.
