Now I have all the key data from Park's textbook. I can see the Red category (syringes without needles), and there's a Blue/White translucent category for sharps (needles). Let me now compile the full answer. I have enough information to write a detailed answer about waste disposal from an injection room as per Park's textbook.
Here is the content on Disposal of Wastes from the Injection Room strictly from Park's Textbook of Preventive and Social Medicine (Chapter on Hospital/Health-Care Waste Management, Bio-Medical Waste Management in India - Rules 2016):

Disposal of Wastes from the Injection Room

(As per Park's Textbook of Preventive and Social Medicine)

Waste generated in an injection room falls under bio-medical waste and is governed by the Bio-Medical Waste Management Rules, 2016 (which superseded the earlier Rules of 1998). The key principle is segregation at the point of generation using a colour-coded bag/container system.

Colour-Coded Segregation System (Schedule 1, Part 1)

The wastes typically produced in an injection room - syringes, needles, cotton swabs, IV tubes, vials, ampoules - fall into these specific categories:

1. YELLOW BAG / CONTAINER

Type of WasteTreatment & Disposal
(c) Soiled waste - cotton swabs, dressings, plaster casts contaminated with blood/body fluids; bags containing residual or discarded bloodIncineration or plasma pyrolysis or deep burial. In absence of these: autoclaving or microwaving/hydroclaving followed by shredding or mutilation, then sent for energy recovery.
(d) Expired/discarded medicines - antibiotics, cytotoxic drugs, glass or plastic ampoules, vials etc.Cytotoxic drugs/items to be returned to manufacturer or sent for incineration at >1200°C or plasma pyrolysis at >1200°C. All other discarded medicines sent back to manufacturer or disposed by incineration.

2. RED BAG / CONTAINER

Type of WasteTreatment & Disposal
Contaminated waste (Recyclable): Disposable items such as tubing, bottles, IV tubes and sets, catheters, urine bags, syringes (without needles, and fixed-needle syringes with needles cut), vaccutainers (with needles cut), glovesAutoclaving or microwaving/hydroclaving followed by shredding or mutilation or a combination of sterilization + shredding. Treated waste sent to registered/authorized recyclers or for energy recovery or plastics recycling.

3. BLUE / WHITE TRANSLUCENT PUNCTURE-PROOF CONTAINER

Type of WasteTreatment & Disposal
Waste sharps (both used and unused): Needles, syringes with fixed needles, needles from needle-tip cutters or burners, scalpels, blades, or any other contaminated sharp object that may cause puncture and cutsAutoclaving or microwaving or dry heat sterilization followed by shredding or mutilation or encapsulation in metal container or cement concrete; sent to authorized/registered recyclers. OR: At primary level facilities, Sharp pits may be used.

Key Notes from Part-2 of Schedule 1

  1. Needle handling (Point 11): Syringes should be either mutilated or needles should be cut and stored in tamper-proof, leak-proof and puncture-proof containers for sharp storage. Where the occupier is not linked to a disposal facility, it is the occupier's responsibility to sterilize and dispose as prescribed.
  2. No recapping: Used needles must not be recapped - they go directly into the puncture-proof sharps container.
  3. Chemical treatment: At least 10% Sodium Hypochlorite (with 30% residual chlorine) for 20 minutes, or any equivalent chemical reagent demonstrating Log₁₀ 4 reduction efficiency for micro-organisms.
  4. Segregation at point of generation: Bio-medical waste must be segregated into containers/bags at the point of generation of the waste (i.e., at the injection room itself).
  5. COVID-19 precaution note (added): Foot-operated lids in colour-coded bins must be used to avoid contact. All waste handlers must follow hand washing, gloves, masks, and other PPE.
