Electronics are the fastest growing trash group on the planet.
 It is estimated that 41.8 million metric tonnes (Mt) of electronic waste were produced in 2014 alone.
 That number is also estimated to rise to 50 million metric tonnes by 2018.
 Of the 41.8 million Mt of electronic waste in 2014, three million Mt were small IT devices such as cell phones, pocket calculators, tablets, personal computers, etc.
 An additional 12.8 million Mt was items such as vacuum cleaners, electric shavers, and video cameras.
 Due to the increase in electronic waste being created there is also an increase in the amount batteries being thrown away.
 Americans alone dispose of over three billion batteries a year.
 At least 14,000 tons of those three billion batteries are rechargeable Many rechargeable devices, such as those listed above, utilize a Lithium-ion battery (LIB) as their source of power.
 The issue is that electronic devices are one of the only items disposed of even if they are not broken or defective.
 In the case of current technology, new is already old.
 Items that become obsolete are as susceptible to being thrown as ones that are broken.
 Because of this trend, more and more electronic devices, along with their batteries, are being thrown away improperly.
 The goal of this page is to increase the awareness of the potential environmental effects of cobalt from lithium ion batteries.
