Step 1: Recall the Bio-medical Waste (BMW) Rules 2016.
The Government of India (MoEFCC) simplified the categorization of biomedical waste into 4 color-coded groups. These categories are used for segregation, collection, treatment, and disposal:
- Yellow Category: Human/animal anatomical waste, soiled waste (like dressings, bandages), expired medicines, chemical waste, incineration ash, etc. Disposal usually by incineration, deep burial, or chemical treatment.
- Red Category: Contaminated, recyclable plastic waste such as catheters, IV tubes, urine bags, syringes (without needles), gloves, etc. Disposal by autoclaving/microwaving and recycling.
- Blue Category: Glassware, metallic implants, and other sharps like broken ampoules, vials (excluding those contaminated with cytotoxic waste). Disposal after sterilization and recycling.
- White (Translucent) Category: Sharps such as needles, syringes with fixed needles, scalpels, blades. These are disposed of in puncture-proof containers followed by autoclaving/dry heat sterilization.
Step 2: Check the given options.
- Yellow → Valid category.
- Red → Valid category.
- Blue → Valid category.
- Green → Not a category in BMW 2016 rules.
Step 3: Conclusion.
The category "Green" does not exist in the Bio-medical Waste Management Rules, 2016.
