Use Rechargeable Batteries
Use rechargeable batteries instead of disposable ones. This will save you money and have much less of an impact on the environment than disposable batteries. Rechargeable batteries can be reused hundreds, or sometimes thousands of times, leaving much less pollution in our landfills. They are similar to traditional alkaline batteries, but the chemical reactions that occur inside a rechargeable battery are reversible, allowing them to be recharged again and again.
The most ecological rechargeable batteries are Ni-MH rechargeable units (Nickel-metal hydride) These are safer for the environment than nickel cadmium (NiCd) rechargeable batteries.
When rechargeable batteries are not an option, lithium and titanium batteries are an attractive alternative. These are recommended for critical devices such as smoke detectors and flashlights. This type of battery lasts much longer which reduces wastage.
Rechargable batteries can now be returned on campus for recycling. For more information visit http://www.mun.ca/sustain/initiatives/batteries.php
