Hazardous, Universal, & Electronic Waste Disposal for Businesses

The IWMA has programs to help businesses manage their hazardous, universal and electronic waste. State and Federal laws govern these programs and restrictions apply.  If you are unsure whether your waste is hazardous, universal, or e-waste, please refer to our Hazardous Waste Program Page.

To dispose of hazardous, universal, and/or electronic waste please complete the
