UNEP Report on Safe Disposal of Unused Medicines: Tackling Pollution and AMR Through One Health
The United Nations Environment Programme (UNEP) released its pivotal 2026 report, “Safe Disposal of Unused Medicines — A One Health Approach for National Systems,” on March 11, highlighting the severe risks of improper pharmaceutical disposal. Common practices like flushing unused drugs down toilets or landfilling them release residues into water, soil, and air, driving antimicrobial resistance (AMR), endocrine disruption, toxicity, and poisoning risks.
Global Scale of Pharmaceutical Waste
Globally, up to 50% of household medicines become waste due to over-prescription, patient non-adherence, improper storage, and expiry, accounting for about 3% of hazardous healthcare waste. The unused medicine management market is projected to reach US$2.54 billion by 2032, fueled by rising healthcare spending and drug consumption.
Unused pharmaceuticals pose direct ecological harm: residues in effluents affect aquatic life (e.g., impaired fertility, behavioral changes) and indirectly fuel AMR—a global crisis where antibiotics lose efficacy, linked to improper disposal of antimicrobials. Human health threats include accidental poisoning (especially children), suicides, and re-entry of residues via food chains.
One Health Framework: Four Pillars
The report advocates a One Health approach—integrating human, animal, and environmental health—via a multisectoral four-pillar framework spanning households, healthcare, agriculture, and veterinary sectors.
Pillar 1: Waste Prevention (Priority Focus)
Prevention at source is paramount to avoid generation costs and pollution.
- Better Prescribing: Diagnostics, unit-dose packaging (exact quantities), and digital tools to curb over-prescription and stockpiling.
- Disease Prevention: Strengthen WASH, biosecurity, vaccinations to reduce medicine demand.
- Redistribution: Up to 19% of unused drugs could be safely redistributed (e.g., Netherlands’ PharmaSwap platform) with quality checks.
Pillar 2: Comprehensive Take-Back Schemes
Nationwide programs for safe returns:
- Household drop-offs at pharmacies (e.g., Return Unwanted Medicines – RUM bins).
- Farm and facility collections, with secure transport to treatment sites.
- Avoid flushing or trash; incineration or controlled landfilling for residuals.
Pillar 3: Legal and Policy Frameworks
- Extended Producer Responsibility (EPR): Shift costs to pharma companies for collection/treatment.
- Regulations banning improper disposal, with monitoring via digital tracking.
- Integrate into national waste policies and AMR action plans.
Pillar 4: Awareness-Raising
Multisector campaigns on risks and proper practices, targeting prescribers, patients, and farmers.
Environmental and Health Impacts
Pharmaceutical residues persist in ecosystems:
- AMR Driver: Unused antibiotics select resistant bacteria in wastewater.
- Toxicity: Hormones disrupt reproduction; cytostatics harm cells.
- Pollution Pathways: Sewage treatment fails to remove many APIs; leach into groundwater.
India context: CDSCO guidelines (2025) outline disposal but note a “Flush List” of 17 drugs—contrasting UNEP’s prevention focus. Nationally, pharma waste contributes to river pollution (e.g., Ganga), amplifying AMR threats.
Recommendations for Implementation
UNEP calls for:
-
Policy Integration: Embed in national action plans on pollution, AMR, and chemicals.
-
Digital Tools: Track consumption/disposal for transparency.
-
International Cooperation: Share best practices (e.g., EU EPR models).
-
India-Specific: Scale pharmacy take-backs, EPR under Plastic Waste Rules extension, awareness via Ayushman Bharat.
Economic rationale: Prevention slashes disposal costs; market growth signals investment opportunities.
Global and Indian Context
UNEP builds on prior reports (e.g., 2023 antimicrobials-AMR link), aligning with WHO One Health Joint Plan. Examples: Netherlands’ PharmaSwap; Ireland’s proposed DUMP scheme.
For India, with a booming pharma sector, urgent need amid rising AMR (10 lakh deaths/year globally). UPSC links: Pollution (Art 48A), Health (SDG 3/6), International Env Law.
