One way to reduce waste batteries is to buy rechargeable batteries instead of disposable ones. Disposable batteries are cheaper to purchase, but their frequent replacement especially for high-energy device makes them more expensive in the long run.
Rechargeable batteries are therefore a simpler and more economical solution. Reusable hundreds of times, they help reduce the consumption of metals such as lithium, cobalt, nickel, and manganese. By limiting the production of new batteries, they also reduce greenhouse gas emissions and the amount of hazardous waste.
