How to reduce electronic waste
Reconsider upgrading your cell phone every year.
Many mobile phone carriers offer incentives to purchase new devices or offer early upgrades to get you to spend more money. Sure, getting the latest hi-tech phone would be nice, but if your current device still works, there may be no need to upgrade.
Consider keeping it for another year, or as long as it lasts you. Avoid the temptation to buy a new device just because it's cheap.
