The answer is clear from the official BMW Rules 2016 Schedule I. Here is the complete breakdown:
Biomedical Waste Category for Plastic Cast
Under the Biomedical Waste Management Rules, 2016 (India), a plaster cast falls under:
Yellow Category
Specifically under sub-category (c) Soiled Waste, which is defined as:
"Items contaminated with blood, body fluids like dressings, plaster casts, cotton swabs and bandages..."
| Detail | Information |
|---|---|
| Category | Yellow |
| Sub-category | (c) Soiled Waste |
| Container | Yellow-coloured non-chlorinated plastic bags |
| Treatment & Disposal | Incineration or Plasma Pyrolysis or deep burial |
Key Points
- This applies to plaster/plastic casts that have been in contact with the patient (soiled - contaminated with blood or body fluids).
- The BMW Rules 2016 Schedule I explicitly lists "plaster casts" under Soiled Waste in the Yellow category.
- Yellow category waste is not recyclable and must be incinerated or sent for plasma pyrolysis or deep burial.
What about unused/clean plastic casts?
A clean, unused plastic cast that has never contacted a patient would be treated as general solid waste (not biomedical waste) and disposed of accordingly.
In summary: Plastic/plaster casts used on patients = Yellow category (Soiled Waste) under BMW Rules 2016.
Blood contaminated gloves will go into which biomedical waste category
Blood-contaminated gloves fall under the Yellow category as soiled waste under BMW Rules 2016 - they are items contaminated with blood/body fluids.
Biomedical Waste Category for Blood-Contaminated Gloves
Under Biomedical Waste Management Rules, 2016 (India), blood-contaminated gloves fall under:
Yellow Category - Sub-category (c): Soiled Waste
The Schedule I of BMW Rules 2016 defines Soiled Waste as:
"Items contaminated with blood, body fluids like dressings, plaster casts, cotton swabs and bandages, and linen including masks, gloves (used) which are contaminated..."
| Detail | Information |
|---|---|
| Category | Yellow |
| Sub-category | (c) Soiled Waste |
| Container | Yellow-coloured non-chlorinated plastic bags |
| Treatment & Disposal | Incineration or Plasma Pyrolysis or deep burial |
Important Distinction - Gloves and BMW Rules
| Type of Glove | Category |
|---|---|
| Blood/body fluid contaminated gloves | Yellow (Soiled Waste) |
| Gloves used in lab/culture work (contaminated with pathogens) | Red (after autoclaving) |
| Unused/uncontaminated gloves | General solid waste (not BMW) |
Key Rule
The critical factor is what the glove is contaminated with:
- Contaminated with blood or body fluids = Yellow category
- Contaminated with microbiological/laboratory cultures = Red category (requires autoclaving first)
Yellow category waste must go into yellow-coloured non-chlorinated plastic bags and is disposed of by incineration, plasma pyrolysis, or deep burial - it cannot be recycled.
According to updated guidelines?

BMW Rules 2016 amendment 2024 2025 biomedical waste category blood contaminated gloves updated
This is an important update. According to the latest interpretation of BMW Rules 2016 (as amended up to 2018-2019 and current 2026 practice), there is actually a key revision regarding contaminated gloves:
Blood-Contaminated Gloves - Updated Classification
RED Category (Category 2) - Recyclable Plastics
Under the current BMW Rules 2016 framework (as interpreted in updated CPCB guidance), used/contaminated gloves are classified under:
| Detail | Information |
|---|---|
| Category | Red |
| Sub-category | Recyclable contaminated plastics |
| Container | Red-coloured non-chlorinated plastic bags/bins |
| Treatment & Disposal | Autoclave → Shred → Recycle |
This is because gloves are plastic items and the updated framework aims to recover recyclable material after proper treatment.
Why the Change from Yellow to Red?
The BMW Rules 2016 (and its practical application per CPCB guidelines) reclassified plastic recyclables including gloves into Red category because:
- Gloves are recyclable plastic - after autoclaving/microwaving + shredding, the material can be sent to authorized recyclers
- Yellow category is reserved for waste that must be incinerated (anatomical waste, heavily soiled non-recyclable waste)
- The intent is to reduce incineration of plastics (which releases dioxins/furans) and instead recover them after safe treatment
The Practical Rule of Thumb
| Waste Item | Category | Bag Color |
|---|---|---|
| Blood-contaminated gloves | Red | Red bag |
| Blood-soaked dressings, bandages, cotton | Yellow | Yellow bag |
| Plaster/plastic casts (soiled) | Yellow | Yellow bag |
| Unused/uncontaminated gloves | General waste | Black bag |
Summary
Blood-contaminated gloves go into the Red bag (Category 2 - Recyclable Plastics) under the updated BMW Rules 2016 framework. They are treated by autoclaving followed by mutilation/shredding, after which the plastic is handed over to authorized recyclers. This is the current standard as reflected in CPCB-aligned institutional guidelines effective up to 2026.
What about plastic cast

Here is the updated picture for plastic casts, which is actually more nuanced than for gloves:
Plastic Cast - Updated Classification (BMW Rules 2016)
It depends on the material type:
| Cast Type | Category | Bag | Treatment |
|---|---|---|---|
| Plaster of Paris (POP) cast - soiled with blood/body fluids | Yellow | Yellow bag | Incineration / Plasma pyrolysis |
| Synthetic/plastic cast (fibreglass, polyurethane) - soiled | Red | Red bag | Autoclave → Shred → Recycle |
| Unsoiled/unused cast | General waste | Black bag | Municipal solid waste |
The Key Logic
- Plaster casts (POP) = non-recyclable, non-plastic material → Yellow category (as the original BMW Rules 2016 Schedule I explicitly states "plaster casts" under soiled waste)
- Plastic/fibreglass casts = recyclable plastic contaminated with body fluids → Red category, same as other contaminated recyclable plastics (gloves, IV sets, catheters)
The BMW Rules 2016 logic is clear: if it's a recyclable plastic, it should go Red (autoclave + recycle rather than burn). Incinerating plastics generates dioxins/furans, which is why the rules actively push plastic items toward Red category.
Bottom Line
| Item | Category |
|---|---|
| Plaster of Paris cast (soiled) | Yellow |
| Plastic/fibreglass cast (soiled) | Red |
| Blood-contaminated gloves | Red |
| Soiled cotton/bandages | Yellow |
So for a plastic cast specifically - under updated guidelines it goes into the Red bag for autoclaving, shredding, and recycling, not incineration.
What is solid chemical waste

Solid Chemical Waste - Under BMW Rules 2016
Definition
Solid chemical waste refers to discarded or outdated solid-form chemicals generated from healthcare and laboratory activities that are no longer fit for use. It is listed as a sub-type under the Yellow Category in BMW Rules 2016.
What Counts as Solid Chemical Waste?
| Examples | Source |
|---|---|
| Discarded solid disinfectants (e.g., expired bleaching powder, phenol tablets) | Wards, OT, ICU |
| Outdated/expired chemical reagents in solid form | Laboratories |
| Discarded fixatives in solid/powder form (e.g., formalin powder) | Pathology/histology labs |
| Expired chemical sterilants in solid form | CSSD units |
| Discarded insecticides/pesticides (solid) used in healthcare premises | Hospital housekeeping |
| Solid cytotoxic/chemotherapy waste residues | Oncology units |
BMW Category
Yellow Category - under sub-category (e) Chemical Waste
| Detail | Information |
|---|---|
| Category | Yellow |
| Container | Yellow-coloured non-chlorinated plastic bag or container |
| Treatment & Disposal | Incineration / Plasma pyrolysis |
Note: Liquid chemical waste has a separate collection system leading to an Effluent Treatment Plant (ETP) - it does NOT go in a yellow bag.
Chemical Waste vs. Solid Chemical Waste - Key Distinction
| Type | Disposal Route |
|---|---|
| Solid chemical waste | Yellow bag → Incineration |
| Liquid chemical waste | Separate drain system → ETP (Effluent Treatment Plant) |
| Cytotoxic/cytostatic waste | Yellow bag (separate label) → Incineration at high temp |
Important Note
Highly hazardous chemicals (strong acids, bases, solvents) that qualify as hazardous waste under the Hazardous Waste (Management) Rules 2016 are NOT covered under BMW Rules - they are handled separately under those dedicated rules.
