The Unseen Epidemic in Our Healthcare System
Walk into any hospital in Bandar Abbas, and you'll witness the pulse of healthcare: doctors making rounds, nurses administering medications, technicians running diagnostics. But beneath this life-saving machinery flows a hidden torrent of hazardous materials—used syringes, blood-soaked bandages, expired chemotherapy drugs, and discarded plastics.
With Iran's southern hub home to over 1.5 million people and multiple major hospitals, the city generates tons of medical waste daily, much of which could contaminate coastal ecosystems or enter the food chain if mismanaged 3 7 . Unlike household trash, this waste carries pathogens, toxic chemicals, and radioactive residues.
Medical Waste Facts
- 15-25% of hospital waste is hazardous
- Coastal heat accelerates decomposition
- Antibiotics detected in wastewater
Decoding Hospital Waste: What's in the Stream?
Healthcare waste isn't a monolith. The World Health Organization (WHO) categorizes it by risk level, a framework adopted in Iran:
General Waste (75-85%)
Food scraps, paper, and non-infectious packaging.
In Bandar Abbas, coastal humidity and high temperatures accelerate decomposition, increasing leakage risks into the Persian Gulf. Studies confirm pharmaceuticals like antibiotics persist through treatment plants, threatening marine life and antibiotic resistance 3 4 .

Anatomy of a Crisis: The 2025 Tehran VOC Experiment
While Bandar Abbas faces distinct challenges, a landmark 2025 study in Tehran exposed universal risks of "green" waste tech. Researchers investigated volatile organic compounds (VOCs) emitted by non-incineration devices—critical as Iran phases out polluting incinerators.
Methodology: Tracking the Invisible Killers
- Sampling Sites: Air collected near autoclaves, hydroclaves, and shredders in 4 hospitals (public/private) 4 .
- BTEX Capture: Using NIOSH Method 1501, charcoal tubes absorbed benzene, toluene, ethylbenzene, and xylenes over 4 hours.
- Cytotoxicity Testing: Extracted particles applied to human lung cells (A549 line); viability measured via MTT assay.
- Particle Analysis: SEM-EDAX and thermogravimetry characterized particulate matter.
Results: The Stealthy Threat
- Toluene dominated emissions (69.30-136.68 µg/m²), followed by xylene.
- Autoclave-shredder combos showed highest cytotoxicity (cell viability: 42-58%), linked to aerosolized drug residues.
- Hazard Quotient (HQ) exceeded safe limits in 50% of hospitals, indicating chronic risk 4 .
BTEX Emissions and Health Risks in Tehran Hospitals
| Compound | Avg. Concentration (µg/m²) | Primary Health Risk | Max. Hazard Quotient (HQ) |
|---|---|---|---|
| Toluene | 69.30-136.68 | Neurotoxicity | 1.84 |
| m/p-Xylene | 41.22-98.76 | Respiratory irritation | 1.57 |
| Benzene | 7.32-34.80 | Leukemia | 1.09 |
| Ethylbenzene | 12.48-29.64 | Hearing loss | 0.93 |

Bandar Abbas's Battle: Local Realities, Local Solutions
Bandar Abbas's waste profile reflects its geography. Coastal humidity corrodes storage containers, while limited landfill space forces reliance on Kahrizak-style landfills 60+ km away—a journey risking spills 2 6 . Compounding this:
Pharmaceutical Waste Surge
51% of households discard unused meds in trash, contaminating groundwater 3 .
Storage Deficiencies
Only 43% of Iranian hospitals disinfect waste containers; 20% have "poor" sanitary storage 2 .
Training Gaps
Segregation of infectious/general waste remains inconsistent.
Yet hope emerges through Green Hospital initiatives 5 :
- Autoclaving Expansion: Post-COVID, Iranian hospitals like Firouzgar adopted steam-based disinfection, cutting infectious waste by 51% by weight 1 4 .
- Circular Supply Chains: Replacing single-use items with sterilizable alternatives (e.g., surgical trays).
- MedTake-Back Programs: Pilots collecting expired drugs for encapsulation—critical for coastal cities 3 5 .

Bandar Abbas's path forward hinges on localizing global models:
Upgrade Storage & Segregation
Color-coded bins, staff training, and daily monitoring cut cross-contamination.
Scale Non-Burn Tech
Solar-powered autoclaves could exploit the region's 300+ sunny days/year.
Community Take-Back
Partnering with pharmacies to collect expired drugs.
Coastal Sentinel System
Regular monitoring of near-shore water for pharmaceutical residues.
"Our colleagues... procured autoclaves which can assist to a great extent in the disposal of infectious waste"
"First, do no harm" extends beyond the bedside.
It must echo in our waste rooms, our landfills, and our seas.
