There are more than 35 minerals in the majority of modern technology devices
Believe it or not, technology devices like the iPhone 6 rely on precious minerals and metals mined from the earth.

Europium is a phosphor that creates a bright red on an iPhone screen. Cerium gets put into a solvent that workers use to polish devices as they move along the assembly line.”
In addition, rare-earth minerals are crucial ingredients for not just cell phones but wind turbines, hybrid cars and night-vision goggles.

Zinc and steel are 100 percent recyclable
Zinc and steel go together like peanut butter and jelly. As one of the most used materials in the world, steel is 100 percent recyclable. It’s also the most recycled material in the world.
Zinc, which is also 100 percent recyclable, is commonly used in steel to prolong the metals durability. The metal ranks slightly lower than steel with a 80 percent recyclable rate.
