How to Recycle Disposable Batteries Properly

Recycling disposable batteries is an essential step in reducing waste and conserving natural resources. According to the Environmental Protection Agency, over 3 billion batteries are thrown away each year in the United States alone.

First, let's talk about the types of batteries that can be recycled. Alkaline and nickel-cadmium (Ni-Cd) batteries are widely accepted at most recycling centers, but it's essential to check with your local facility to confirm their acceptance.

You can also recycle batteries through community collection events or mail-in programs. Many retailers, such as Home Depot and Lowe's, offer battery recycling programs in their stores.

Properly recycling your batteries is a simple process that requires minimal effort, but it makes a significant impact on the environment.

Safety first! Be sure to safely prep your batteries by bagging or taping them to prevent accidents. You can either bag each battery in its own clear plastic bag or tape the terminals with clear packing, non-conductive electrical or duct tape, keeping the label visible.

Store the batteries in a cool, dry place, away from metal containers and direct sunlight. Incidents can occur when batteries are exposed to hot weather, so keep them in a plastic container to prevent fires.

If you notice a swollen or bulging battery, immediately put it in a non-flammable material like sand or kitty litter in a cool, dry place. Don't throw it away; contact Call2Recycle customer service or the manufacturer for instructions, especially if the label says it's a Lithium or Lithium-Ion battery.

Timing is everything when it comes to recycling batteries. Aim to drop them off within six months, ensuring they're properly bagged or taped. Use a battery recycling locator to find the nearest drop-off site.

To reduce fire risk, store batteries in a non-metal, leakproof container with a lid, such as a plastic bucket. Avoid putting batteries in curbside recycling carts or bins, as they may cause a fire if damaged by equipment.

Here's a quick checklist for safe battery recycling:

By following these simple steps, you can help keep batteries out of landfills and prevent potential fires.

Single-Use Batteries can be recycled, but it's essential to know how to handle them properly. Alkaline and Zinc-Carbon batteries can be safely put in your household trash, but it's recommended to send them to battery recyclers or check with your local or state solid waste authority.

Button-Cell or Coin batteries require special care due to the potential swallowing hazard they pose to young children. Store them out of reach of kids and handle them with caution. If damaged, contact the manufacturer for specific handling information.

Lithium Single-Use batteries should never be put in the trash or municipal recycling bins. Check if the battery has the word "lithium" marked on it, and if so, find a recycling location near you.

To safely prep your batteries for recycling, you have two options: bag each battery in its own clear plastic bag or tape the terminals with non-conductive tape, keeping the label visible. This will prevent any damage or sparks that could cause fires.

Here's a quick rundown of the disposal options for different types of single-use batteries:

Remember to store your batteries in a cool, dry place and aim to drop them off for recycling within six months.

There are several types of disposable batteries, including alkaline, nickel-cadmium (Ni-Cd), nickel metal hydride (NiMH), and lithium-ion (Li-ion).

Alkaline batteries are the most common type, accounting for over 90% of disposable batteries. They're widely used in household devices, toys, and other small appliances.

Ni-Cd batteries, on the other hand, have been largely phased out due to their toxic cadmium content. However, they can still be found in older devices and tools.

NiMH batteries are a more environmentally friendly option, but they can be more expensive than alkaline batteries.

Dry cells are a type of battery that uses a chemical reaction to produce electricity.

They're commonly used in small devices like flashlights and toys, and can be found in many household items.

The most common type of dry cell is the zinc-carbon battery, which uses a zinc anode and a manganese dioxide cathode to produce electricity.

These batteries are relatively inexpensive and widely available, making them a popular choice for many applications.

However, they have a limited lifespan and can be toxic if not disposed of properly.

In the automotive industry, batteries are a crucial component. They provide the necessary power to start the engine and run the electrical systems.

Lead-acid batteries are the most common type used in vehicles, accounting for about 95% of the market share. They're relatively inexpensive and well-suited for starting engines.

Lithium-ion batteries are gaining popularity in electric vehicles, offering a more efficient and environmentally friendly option. They have a longer lifespan than lead-acid batteries and can handle more charge cycles.

Nickel-metal hydride batteries are another type used in hybrid vehicles, providing a balance between cost and performance. They're also known for their high energy density.

In electric vehicles, battery size and type can greatly impact performance and range. For example, the Tesla Model S uses a large lithium-ion battery pack to achieve its impressive range.

The recycling process for disposable batteries starts by sorting them into chemistries, such as lead acid, nickel-cadmium, nickel-metal-hydride, and lithium ion.

Collection centers place these batteries into designated drums, sacks, or boxes to make them available for recycling.

The process begins by removing combustible materials like plastics and insulation with a gas-fired thermal oxidizer.

Polluting particles from this burning process are eliminated by the plant's scrubber before release into the atmosphere.

The clean and naked cells are then chopped into small pieces and heated until the metal liquefies.

Non-metallic substances are burned off, leaving a black slag on top that a slag arm removes.

Cadmium vaporizes at high temperatures and is blown into a large tube cooled with water mist, producing 99.95 percent pure cadmium.

The liquid metals are then poured into "pigs" or "hogs" that weigh 65 pounds or 2,000 pounds respectively, or into smaller nuggets weighing 7 pounds.

These metal-filled containers are shipped to metal recovery plants where they're used to produce nickel, chromium, and iron for stainless steel and other products.

Battery recycling is energy-intensive, taking 6 to 10 times more energy to reclaim metals from some recycled batteries than from mining.

However, lead from lead acid batteries can be extracted easily and reused without elaborate processes, making it an exception.

Disposal and collection of disposable batteries requires careful attention to safety procedures. Battery collectors, transporters, and recyclers must follow universal and hazardous waste requirements.

In the United States, the U.S. Department of Transportation has specific regulations for transporting used batteries from households and businesses. These regulations aim to prevent fires and ensure safe transportation.

To prevent fires, there are several best management practices and products available, such as those provided by Call2Recycle. Their battery safety information and training resources can help you learn more about safe battery handling and disposal.

Here are some key resources to keep in mind:

To dispose of batteries in a glass bin, place the clear, zip-sealed bag of batteries on top of the glass in your glass recycling bin. Make sure the recycling truck driver can see the bag, and don't put glass on top of the bag of batteries.

If you don't have a glass bin, you can put the bag of batteries into an empty glass bin and set it at the curb. If you don't have a bin for glass recycling at all, contact your garbage company to request one - it's usually included in the service.

If your glass recycling bin was stolen, your garbage company will replace it for no charge.

When handling batteries, it's essential to follow the right guidelines for disposal and collection.

The bag must be fully sealed.

If you're using smaller bags, they should be clear and zip-sealed, with a capacity of no more than 1 quart.

Larger bags are not allowed, regardless of their contents.

You can put both untaped and taped batteries together in a single bag.

If you're a business or non-household, you'll need to follow special requirements for managing batteries. Many batteries are regulated as universal waste when not generated by households, so be sure to check the guidelines for managing universal waste in Wisconsin.

For businesses, schools, and other non-households, batteries are subject to hazardous waste requirements. This means that some batteries can be put in the trash, but others must be recycled or managed as universal waste. To learn more, check out the publications "Battery Recycling for Businesses (WA-1622)" and "How to Handle Universal Waste: Batteries (WA-1809)".

Retailers also have specific requirements for battery recycling. They must charge a deposit on the sale of an automotive type replacement battery and refund it upon request when a customer returns a used battery. Customers can bring in used batteries for recycling at participating retailers, and some retailers may even offer free recycling for customers who purchase a new battery.
