Which waste streams are typically used for used pipette tips and microcentrifuge tubes in ABE labs?

• A. Designated biohazard waste containers (e.g., red bags or labeled bins) for disposal.
• B. Regular trash.
• C. Recycling only.
• D. Compost.

Answer: (A)

Waste segregation in ABE labs emphasizes treating items that may be contaminated with biological materials as biohazard waste. Used pipette tips and microcentrifuge tubes often carry biological residues or infectious agents, so they belong in designated biohazard waste containers (red bags or labeled bins). This ensures they are contained and properly processed, typically through autoclaving or other approved decontamination methods, before final disposal. Placing them in regular trash risks exposure and environmental contamination; recycling is not appropriate because contamination can transfer biological material to other products, and composting is unsafe for biohazardous waste. Always use the designated biohazard stream for these items.
