How to Dispose of Trace Chemotherapy Waste
Items holding only residual amounts of chemotherapy drugs go in a yellow trace-chemo container for incineration, not the red-bag, black-RCRA, or autoclave streams.
What counts as trace chemotherapy waste
Trace chemotherapy waste is material that held only residual (trace) amounts of antineoplastic or other hazardous chemotherapy drugs: empty IV bags and tubing, empty vials, and contaminated personal protective equipment such as gloves and gowns. The governing concept is the RCRA-empty container standard at 40 CFR 261.7. For a container that held a non-acute hazardous waste, it is empty when all wastes have been removed using practices commonly employed (pouring, pumping, aspirating) and no more than 2.5 centimeters (1 inch) of residue remains on the bottom, or no more than 3 percent by weight of the total capacity remains for a container of 119 gallons or less. Section 261.7(a)(1) provides that residue remaining in an RCRA-empty container is not subject to regulation under 40 CFR parts 261 through 268, 270, or 124. For healthcare facilities operating under 40 CFR part 266 subpart P, 266.507 supplies parallel empty-container rules: stock bottles, vials, and ampules are empty once drug is removed by common practices, a syringe is empty when the plunger is fully depressed, and an IV bag is empty when the drug has been fully administered to a patient.
The trace-versus-bulk distinction drives the disposal stream. Trace chemo is RCRA-empty material. Bulk chemo (covered on a separate page) is any non-empty container, unused or partially used drug, or anything still holding more than trace residue, and it is managed as RCRA hazardous waste. A critical exception: a container that held a P-listed chemotherapy drug (an acute hazardous waste at 40 CFR 261.33(e)) as its sole active ingredient is NOT brought into the RCRA-empty exemption by triple rinsing in a healthcare setting. Under 266.507(d), residues in all containers other than the listed empty types must be managed as non-creditable hazardous waste pharmaceuticals unless the container held a non-acute drug and is empty under 261.7(b)(1) or (2). In short, the triple-rinse path in 261.7(b)(3) does not let a healthcare facility downgrade a P-listed chemo container to trace.
Step by step: containment, segregation, transport
- Determine whether the item is trace or bulk.
Confirm the item held only residual drug. A non-acute container is RCRA-empty under 40 CFR 261.7(b)(1) when contents are removed by common practices and no more than 1 inch (2.5 centimeters) of residue remains, or no more than 3 percent by weight remains for a container of 119 gallons or less. An IV bag is empty when fully administered to the patient and a syringe when the plunger is fully depressed (40 CFR 266.507). Anything holding more than trace residue, or any P-listed container, is bulk chemo and is handled separately.
- Segregate P-listed chemo out of the trace stream.
Identify whether the drug is P-listed at 40 CFR 261.33(e). Per 40 CFR 266.507(d), a healthcare facility cannot triple-rinse a P-listed sole-active-ingredient container into RCRA-empty status; those residues are managed as non-creditable hazardous waste pharmaceuticals, not trace chemo.
- Place trace items in a yellow trace-chemo container.
Collect RCRA-empty IV bags, tubing, vials, gloves, and gowns in a leak-resistant, puncture-resistant container labeled for trace chemotherapy waste (yellow, marked Trace Chemo or Chemotherapy Waste, Incineration Only). Do not place trace chemo in a red biohazard bag or a black RCRA hazardous waste container. The specific yellow-container and labeling convention is industry and state regulated-medical-waste practice, so verify your state's exact label and color requirements.
- Send the trace stream for incineration.
Trace chemotherapy waste is destroyed by incineration, not by autoclaving or other steam sterilization. Use a permitted medical waste incinerator through a licensed hauler. The incineration-not-autoclave requirement for trace chemo is industry and state regulated-medical-waste practice rather than a single federal EPA mandate; confirm your state rule.
- Document handling under USP 800 and your facility plan.
Follow USP General Chapter 800: trace-contaminated PPE and materials must be placed in containers approved for trace-contaminated hazardous-drug waste at the site of administration and must comply with all applicable disposal requirements. Maintain a written hazardous-drug handling and waste plan and train staff who handle these materials.
Container, color code, and labeling
Trace chemotherapy waste goes in a yellow container labeled for trace chemo (commonly Trace Chemo or Chemotherapy Waste, Incineration Only), kept distinct from the red-bag regulated-medical-waste stream and from the black RCRA hazardous waste container used for bulk chemo. The trace stream is treated by incineration at a permitted medical waste incinerator and is not autoclaved. This color and treatment convention is grounded in state regulated-medical-waste programs and industry standard practice rather than one federal EPA rule, so verify your state's container, label, and treatment requirements. USP General Chapter 800 sets the handling context: it directs that trace-contaminated PPE and other materials be placed in containers approved for trace-contaminated hazardous-drug waste at the site of drug administration and comply with all applicable disposal requirements. Which drugs are hazardous (including antineoplastic chemotherapy agents) is identified by the NIOSH List of Hazardous Drugs in Healthcare Settings, 2024, which supersedes the 2016 list.
Frequently asked questions
What is the difference between trace and bulk chemotherapy waste?
Trace chemo is material that held only residual amounts of chemo drug and meets the RCRA-empty standard in 40 CFR 261.7, such as fully administered IV bags, empty tubing, empty vials, and contaminated gloves and gowns. It is collected as yellow trace-chemo waste for incineration. Bulk chemo is any non-empty container, unused or partially used drug, or item holding more than trace residue, and it is managed as RCRA hazardous waste.
Can I triple-rinse a P-listed chemo vial to make it trace chemo?
Not at a healthcare facility. While 40 CFR 261.7(b)(3) allows triple rinsing to empty acute hazardous waste containers in general, 40 CFR 266.507(d) provides that for healthcare facilities under subpart P, residues in containers that held P-listed pharmaceuticals must be managed as non-creditable hazardous waste pharmaceuticals; the RCRA-empty exemption is extended only to containers that held non-acute drugs and are empty under 261.7(b)(1) or (2).
Is trace chemotherapy waste autoclaved or incinerated?
Trace chemo is incinerated, not autoclaved. It is sent to a permitted medical waste incinerator through a licensed hauler. Autoclaving (steam sterilization) is not used for trace chemo. The incineration requirement is set by state regulated-medical-waste programs and industry standard practice, so confirm your state's specific rule.
Does trace chemo go in a red bag?
No. Trace chemo goes in a yellow container labeled for trace chemotherapy waste, never a red biohazard bag and never a black RCRA hazardous waste container. The yellow-container convention is a regulated-medical-waste and industry standard; check your state for the exact color and label requirements.
