The act of simply tossing them in the trash bin might seem harmless, but it isn’t the right thing to do if you have options. So what happens when a battery reaches the end of its life? If your local municipality allows it, is it safe to simply toss them in the trash? Let’s dive into the intricacies of alkaline, lithium-ion, and other battery disposal.

TLDR: I’m Going To Throw Them Away Anyway – What’s The Best Way To Do It?

Just to get this out of the way – you’re going to see suggestions like ordering a box & mailing it back, waiting for your annual or semi-annual battery pickup from your local trash operator, battery recycling drives, etc. etc. A lot of people take advantage of these – but the truth is that most Americans simply aren’t educated on the risks batteries pose and many don’t care. It’s much harder than it should be to properly dispose of batteries from home. But there is one super-simple way to do it and almost every American has access to it:

Take your batteries to Home Depot, Lowes, Batteries+, Batteries & Bulbs, Target (in some regions), GadgetMates, etc.

You can call ahead if you want to verify that regional laws allow your local store to accept your battery, but in general stores across the country will take care of it for you at no charge.

Can I recycle my batteries at a GadgetMates location?

We at GadgetMates accept small Lithium Ion & Polymer batteries (limit 3 per visit) for recycling at any of our stores that are from:

  • Cell Phones
  • Laptops
  • Tablets
  • Two-Way Radios
  • Scanners
  • Tools

This is part of our broader electronics recycling initiative that we are very passionate about. Please note that due to safety issues we can’t accept any swollen batteries and we can’t yet take things like car batteries (Lead Acid), drill batteries (Nickel Cadmium), backup power packs (Nickel Metal Hydride), or any specialty batteries – but if you give us a call we can advise you on the best way to dispose of those as well.

The Composition of Batteries

What’s Inside a Battery?

Batteries, whether rechargeable or single-use, contain a mix of chemicals. These can include lead, cadmium, zinc, lithium, and even mercury. When left in landfills, these chemicals can leach into the soil and potentially contaminate groundwater sources, pollute habitats for creatures, and cause a range of issues that we know about (and some we may not yet know about in the future).

Batteries, especially the common alkaline ones like AA, AAA, C, D, and 9-volt, contain various components. According to Energizer, a leading battery manufacturer, typical alkaline batteries include:

  • Steel
  • Zinc
  • Manganese
  • Potassium
  • Graphite

Energy is generated when zinc and manganese interact. While manganese is an essential nutrient, in high concentrations, it can lead to adverse health impacts. For instance, former manganese miners and smelters have suffered permanent neurological damage.

Environmental Implications of Improper Battery Disposal

  1. Soil Contamination: Harmful chemicals from batteries can seep into the ground, affecting plant and animal life.
  2. Water Pollution: These chemicals can find their way into water sources, posing risks to aquatic life and even entering our drinking water.
  3. Waste Accumulation: Batteries take up space in landfills, contributing to the growing waste problem.

Safety Concerns with Tossing Batteries

  1. Risk of Fire: Especially with lithium-ion batteries, there’s a risk of fire if they’re punctured or damaged.
  2. Exposure to Harmful Chemicals: Broken batteries can expose these chemicals, posing health risks to humans and animals.

Best Practices for Battery Disposal

  1. Recycling Centers: Many localities have dedicated centers or drop-off points for used batteries.
  2. Retailer Take-Back Programs: Some retailers offer take-back programs, collecting old batteries for safe disposal.
  3. Special Collection Events: Keep an eye out for community events focused on collecting and recycling e-waste.

The Environmental Impact

Toxicity Concerns

One of the primary concerns with batteries is the risk of chemicals leaching into the soil, surface water, and groundwater. This contamination can lead to polluted water sources and crops, resulting in diseases like cancer. However, it’s worth noting that compared to other battery types, alkaline batteries are not especially toxic.

The EPA’s Stance

The Environmental Protection Agency (EPA) acknowledges that in some communities, batteries can be safely put in the trash. However, they recommend sending alkaline batteries to a battery recycler. This doesn’t mean you can simply toss them in your regular recycling bin.

Disposal Policies Across Regions

Inconsistent Guidelines

There’s no shortage of conflicting messages on battery disposal. Governments and battery makers often lack consistent and clear policies. These guidelines can even vary depending on where you reside.

For instance:

  • California classifies batteries as hazardous waste due to the metals and toxic materials they contain. Residents are instructed to take all batteries to hazardous waste disposal facilities.
  • The District of Columbia advises residents to drop off AA batteries for recycling at specific locations, but not in their regular recycling bins.
  • Seattle encourages its residents to take AA batteries to hazardous waste facilities, emphasizing that around 180,000 tons of batteries are discarded in the U.S. annually.
  • In contrast, places like Chicago refuse to accept alkaline batteries at recycling facilities.

Retailers’ Recommendations

Major retailers also have their say in the matter. For instance:

  • Home Depot suggests that alkaline batteries can be thrown in with regular trash.
  • Duracell advises customers to check local and state regulations and explore recycling options.
  • Amazon, selling AA batteries under its Basics line, includes a symbol indicating that the product should be disposed of separately from regular waste.

Why Should Businesses Embrace Battery Recycling? Businesses often use a vast amount of batteries, and proper disposal becomes crucial. So, if you’re pondering the benefits of battery recycling for your company, consider the following:

  • Ease and Convenience: There are programs that allow easy disposal of your commercial batteries, ensuring that the process is hassle-free.
  • Eco-Conscious Solutions: These programs ensure the earth remains unharmed. By recycling batteries, your business your business, its stakeholders, and Mother Earth are protected from potential harm.
