If disposed of correctly they contain non toxic materials

 They are never free.
    Do not expose children under 16 years to cordless phone use, especially younger children whose brains are 75% more susceptible to radiation damage than adults. Replace cordless phones with

corded lines wherever possible. The cordless phone base emits high levels of EMR 24 hours a day, whether it's being used or not.
    Use the phone's speaker and hold the phone away from your head when in use. Corded headsets gather radiation fields from around the phone and turn the user's head into an antenna for the base-

station. Bluetooth headsets create a greater risk from concentrated microwave frequencies by pointing them directly into the ear. Use an air tube headset instead of a corded headset.
    Always keep your cell phone batteries charged to 100% bar strength since a low signal strength will boost the power output of the phone to the tower transmitters and emit stronger radiation.
    Do not carry a cell phone on or near the hip for an extended length of time. The hip produces 80% of the body's red blood cells and is especially vulnerable to EMR damage.
Most people don't realize it, but cell phones are becoming a huge contribution to pollution on our planet right now. The average American gets a new mobile phone at least once every 18 to 24

months. That averages out to 34 phones during a lifetime if you purchased your first phone starting at the age of 18, staggeringly there are many kids who have them even younger.
As part of our "throwaway" society coupled with our voracious appetite for cell phone consumption and usage means that landfills are becoming clogged at an alarming rate with not only computers and

other electronic components, but cell phones as not many people are aware of proper disposal procedures for them. Sadly, it is estimated that over 125 million cell phones are tossed every year,

creating over 65,000 tons of garbage. Knowing that the landfill doesn't have to be the end point of your cell phone's life can greatly reduce the amount of unnecessary wastage produced each year.
The reason why cell phone recycling is important is because they contain some pretty toxic stuff embedded inside their circuitry and displays, toxins such as Arsenic, Lead, and Copper, in addition

to Cadmium, Mercury and Beryllium (a carcinogen which has been linked to cancer), hazardous chemicals you wouldn't want leaching into the environment. If disposed of correctly they contain non

toxic materials that can be recycled and used again, yet instead we pollute the earth even more by trying to produce these components over again from scratch when in reality we already have the

base materials we need without having to strip anymore from our limited natural resources.
