The following fact sheet was prepared by the ECAR Center staff. Once prepared, each ECAR Center fact sheet undergoes a review process with the applicable state environmental agency(ies). You can check on the status of the review process here. Please read the disclaimer on the status page. While we have tried to present a summary of the essential information on this topic, you should be aware that other items, such as local regulations, may apply to you.
What You Need to Know
When you absorb toxic or flammable material in a towel, you haven't made it any less toxic or flammable. Depending on what they have been used for, shop towels may need to be managed as hazardous wastes. But you may be able to be exempt from the full burden of hazardous waste management rules if you send your towels to a qualified commercial laundry service. If you do not send your towels out for cleaning (for example, if you use disposable towels), then the burden is on you to prove that they are not hazardous before you dispose of them. Reusable towels and a qualified laundry service are by far the best bet.
In the state of Idaho, dirty rags/shop towels are subject to the federal RCRA hazardous waste regulations, meaning that they need to be collected in a proper container which is kept closed, labeled, dated and inspected weekly, be managed under accumulation requirements, and sent to a proper RCRA facility for disposal. However, if the contaminated rags are to be commercially laundered and reused rather than disposed of, the state of Georgia will give auto recyclers somewhat of a break by excluding them from the hazardous waste regulations. The rags/towels need to be managed as hazardous waste only until they are picked up by a commercial laundering service.
However, to qualify for this exemption, there must be NO free liquids present in the accumulated rags. Any free liquids must be managed as hazardous waste and the entire rag/solvent mixture may be considered a hazardous waste subject to regulation.
You should also bear in mind that allowing solvents to evaporate from the rags in order to achieve a "no free liquids" state is not permitted. Instead, you may wish to use some sort of solvent extraction or wringing to recover excess solvent amounts if they plan to have rags laundered. Any recovered liquids should be managed in accordance with the regulations.
Finally, contaminated rags or commercial wipes regulated as hazardous waste MAY NOT be burned in a space heater, boiler, industrial furnace, incinerator, or other combustion device operated by the generator, or open burned.
If contaminated rags/used shop towels are not sent to a laundering service, then auto recyclers must determine if the dirty shop towels are hazardous or not before disposing of them. Most likely they are indeed hazardous. Therefore, they must be managed in accordance with hazardous waste regulations. See the ECAR Hazardous Waste Fact Sheet.

Idaho's Hazardous Waste Management Requirements
Federal EPA Standards Applicable to Generators of Hazardous Waste
When an inspector comes to your facility, there are certain things he or she checks to see if you are in compliance with environmental regulations. It makes good sense for you to perform a "self-audit" and catch and correct problems before they result in penalties. Also, there are some compliance incentives associated with self-audits (see Audit Policy Page).
Use the following list to audit your handling of used shop towels.
- Shop towels are exempt from regulation if they are managed correctly and picked up for laundering by a commercial laundry service. Verify that dirty shop towels are managed correctly and picked up for laundering by a commercial laundry service. You must manage your shop towels in accordance with the hazardous waste requirements until they leave your operations.
- Do your shop towels contain free liquids? If so, there is no hazardous waste exemption for rags or soiled clothing contaminated beyond saturation.
Best Management Practices (BMPs)
Most regulations tell you what you have to do to be in compliance, but they don’t explain how to do it. That’s where "best management practices" come into play. BMPs are proven methods that help you to get into compliance and stay there. The following BMPs are recommended for handling used shop towels.
- Avoid using disposable towels. Use cloth towels from an industrial laundry service that is discharging its wastewater into a public sewer system.
- Do not dispose of solvents by pouring them onto rags or into containers of used shop towels.
- Do not saturate your towels. If you do, wring them out and reuse the liquid.
- Spray minimum amount of solvent onto rags instead of soaking rags.
- Use non-hazardous solvents whenever possible.
- Do not throw dirty wipes, paper towels or rags into the dumpster if they have come into contact with hazardous solvents or waste.
- Do not dispose of dirty shop towels in vehicles to be crushed or shredded.
- Keep waste shop towels in a closed, fireproof metal container labeled "Used Shop Towels."
- To reduce the risk of spontaneous combustion when storing shop towels in metal cans, keep the towels moist with water.
- Examine your equipment cleaning practices to identify opportunities to reduce their frequency, thereby reducing the number of towels, wipes, or rags that are used for this purpose.
- Maintain records of analytical waste determinations and disposal receipts for at least 3 years.
