Waste Recyling Information
Solvents and Solvent Tanks
Waste haulers often provide parts washer solvent tanks for cleaning parts and tools. Solvents used include mineral spirits, Stoddard solvent, petroleum naphtha, and xylene. When no longer useable, these and other solvents become hazardous wastes because they are ignitable and/or toxic. Always check the Material Safety Data Sheet (MSDS) to determine the proper disposal method for any solvent.
-
Consider using less hazardous solvents or switching to a spray cabinet parts washer that does not use solvent.
-
Install a filter on your solvent sink to greatly increase the life of the solvent. Dispose of the filters as hazardous wastes.
-
Make sure solvent is too dirty to use before it is exchanged for new solvent.
-
Use only the number of parts washers that are necessary.
-
Consider purchasing your own solvent still and recycling solvent on-site. Keep a log of dates, recycled amounts, and batch make-up amounts.
-
Remember that sludges, filters, and still bottoms generated from on-site solvent recycling are typically hazardous.
-
Keep different types of solvents in separate, clearly labeled, closed containers.
|
-
Don’t dispose of spent solvents by pouring them on the ground or into drains, or by evaporating them in the air.
-
Don’t mix solvents with any other wastes.
-
Don't get solvents near used oil, the oil can pick up characteristics of the solvent and become a hazardous waste.
