Never Throw in the Trash
Calculators contain metals that are hazardous if disposed of improperly, so don’t throw them in the trash.
Alternative Ways to Recycle
Trade In Your Calculator for Cash
As long as your calculator still works, you can sell it to sellyourcalculators.com. Not only do you get cash, but your calculator gets reused and you keep one more piece of e-waste out of the landfill.

Ways to Reduce
Use Your Smartphone’s Calculator
If you have a smartphone, consider the calculator application for basic arithmetic instead of buying another calculator. Most computers also come with a simple calculator, and you can download graphing applications for free.
