Quick Summary / TL;DR Hazardous Waste:  Materials that are ignitable, corrosive, reactive, or toxic (e.g., chemicals, mercury, chemo waste). Regulated strictly by the EPA and RCRA. Non-Hazardous Waste:  General waste like paper, cardboard, and non-toxic plastics. The Bottom Line:  Mixing these wastes leads to "over-classification" (higher costs) or regulatory fines from the ADEQ. Proper segregation is a legal and financial necessity for Arizona healthcare facilities. Whether
