Understanding the Importance of Proper Battery Disposal
Lithium batteries are widely used in various electronic devices, including laptops, mobile phones, and power tools. These batteries contain harmful chemicals that can pose risks if not disposed of properly. Singapore’s National Environment Agency (NEA) has implemented regulations to ensure safe and responsible battery disposal, protecting both human health and the environment.
Designated Collection Points
NEA’s Green Collection Points (GCPs)
- Number of GCPs: 36
- Location: HDB void decks and shopping malls islandwide
Retail Electronics Stores
- Participating retailers: Harvey Norman, Best Denki, COURTS, Challenger, Mega Discount Store
- Drop-off procedure: Present the used batteries at their designated collection bins
Mobile Collection Activities
- Environmental Service Providers (ESPs) conduct mobile collections at various locations
- Schedule: Check with NEA’s website or contact the ESPs directly
Why Dispose Lithium Batteries Correctly?
Environmental Concerns:
* Lithium batteries contain heavy metals and hazardous chemicals that can leach into the environment if disposed of improperly.
* Improper disposal can contaminate soil, groundwater, and waterways.
Health Risks:
* Lithium batteries release toxic gases when burned or exposed to high temperatures.
* Inhalation of these gases can cause respiratory problems and other health issues.
Fire Hazards:
* Lithium batteries can ignite and cause fires if not managed safely during disposal.
* They can release flammable and explosive compounds when damaged or overheated.
Financial Penalties:
* Singapore’s Environmental Protection and Management Act (EPMA) imposes penalties for improper battery disposal.
* Individuals found littering or disposing batteries illegally may face fines of up to S$1,000.
Types of Lithium Batteries Collected
Primary (Non-Rechargeable) Batteries:
* Button cells (used in watches, calculators)
* AA, AAA, C, D batteries
Secondary (Rechargeable) Batteries:
* Lithium-ion (Li-ion) batteries (used in laptops, mobile phones)
* Lithium-polymer (Li-Po) batteries (used in drones, power tools)
* Lithium iron phosphate (LiFePO4) batteries (used in electric vehicles)
Common Mistakes to Avoid
Do Not:
- Discard lithium batteries in general waste bins.
- Burn or incinerate lithium batteries.
- Attempt to recharge non-rechargeable batteries.
- Mix different types of batteries in the same collection point.

Innovative Ideas for Battery Recycling
RVD-E:
Researchers at Singapore’s Nanyang Technological University have developed a novel chemical process called RVD-E. This process allows the direct extraction and recovery of lithium from spent lithium-ion batteries, paving the way for sustainable battery recycling.
