All nanomaterial waste should be handled as chemical waste. Contaminated solid waste (paper, gloves, wipes, tips) should be collected and submitted using the online chemical waste pick-up form available on the EHS website. Pure unused nanomaterials in solid or powder form should be containerized and submitted as waste. Nanomaterials dissolved or suspended in solvents or formulations should also be collected following the waste handling rules outlined in Chapter 12 and submitted as a chemical waste mixture.
