The Complete Guide to Trace Chemo Disposal in California (2025 Update)

Trace chemotherapy waste disposal in California is one of the most regulated, and most misunderstood, medical waste categories. Because California enforces some of the strictest medical waste laws in the country, any facility that handles chemotherapy drugs must follow strict disposal, storage, labeling, and transport protocols.

This comprehensive guide explains what trace chemo waste is, how California requires it to be disposed of, and how MET provides compliant, cost-effective trace chemo disposal services throughout the state.

What Is Trace Chemotherapy Waste? (California Definition)

California classifies trace chemotherapy waste as any item contaminated with residual amounts (< 3%) of chemotherapy or antineoplastic drugs, but not full-strength or bulk chemo.

Examples of trace chemo waste include:

• Empty or nearly empty syringes

• Gowns, masks, and chemo PPE

• IV tubing and infusion bags

• Empty vials, ampules, and packaging

• Contaminated pads, wipes, and drapes

California Trace Chemo Disposal Regulations (2025)

1. Use Yellow Trace Chemo Containers

California requires:

• Rigid, leak-proof, puncture-resistant yellow containers

• Clear “Trace Chemotherapy Waste” labeling

• Lids that close securely for transport

2. Segregate Waste Properly

Trace chemo must never be mixed with:

• Regular biohazard/red-bag waste

• Sharps (unless contaminated with chemo)

• RCRA hazardous waste

• Pharmaceutical/non-chemo waste

3. Follow Strict Storage Limits

California storage time limits:
