Dispose of properly
Liquid resin should be cured before being disposed of. Simply place liquid resin into a clear container and set it in direct sunlight. Once it's cured, it can be treated as regular waste.
For empty bottles, remove the lid and place in direct sunlight. Once it's cured, it can be treated as regular waste.
Never pour liquid resin into your plumbing, as it is hazardous waste and illegal in most states/provinces.
For Resin Saturated Alcohol
Always contact a local hazardous waste disposal service to ensure resin-saturated Isopropyl Alcohol is properly disposed of according to local regulations.
