Do consider using less hazardous solvents or switching to a spray cabinet parts washer that doesn’t use solvent
Do consider purchasing a solvent distillation unit and recycling spent solvent onsite. (Sludges, filters and still bottoms generated from onsite solvent distillation (recycling) are typically hazardous waste and must be managed as such.)
Do ensure if you recycle onsite, you keep a log of dates, recycled amounts and batch make-up amounts.
Do make sure solvent is too dirty to use before it is exchanged for new solvent.
Do keep different types of solvents in separate, labeled, and closed containers.
Do install a filter on your solvent sink to greatly increase the life of the solvent (but remember to make a hazardous waste determination on the filters to be disposed and manage them appropriately).
Do ensure if you have other waste solvents, you keep them in separate, appropriately labeled containers.
Don’t dispose of spent solvents by pouring them into a storm drain, septic system, dry well, or sewer and never pour solvents onto the ground.
Don’t mix solvents with any other waste. Don’t use solvents near used oil, they may make the used oil a hazardous waste.
Don’t evaporate solvents as a means of disposal.
