Those who have been browsing these mysterious waters of the Internet for a while will surely remember the series of videos. "Will It Blend?", in which a really crazy man beat all sorts of randomness including iPhones in a blender as the promotional for the equipment. Now British scientists have decided to follow the same idea, but with a slightly different intent.
The idea of Plymouth University researchers Arjan Dijkstra and Colin Wilkins was to take a closer look at the materials that make up the iPhone. To do this, the scientists processed the device in a blender and cooked the resulting powder, mixed with sodium peroxide, at temperatures up to 500 ° C until everything was properly melted. This fluid was then dissolved in a nitric acid solution and analyzed on a mass spectrometer, as can be seen from the above video.
The findings were revealing: the iPhone (in this case, a 4s) made up of 33 grams of iron, 7 grams of chrome and 13 grams of silicon. Other materials, found to a lesser extent, include cobalt, tungsten, molybdenum, dyspresium, neodymium, praseodymium, and gadolinium.
The iPhone surveyed also had 90mg of silver and 36mg of gold meaning we are basically talking about a little gem in your hands. Interesting to note, too, that to build a single iPhone it is necessary to mine between 10kg and 15kg of rocks.
The purpose of the research, according to the scientists, was to demonstrate that we need to do more research on what is contained in the electronics we use daily to encourage recycling and pressure companies not to use materials from violent or exploitative areas. Look at Dr. Wilkins's opinion:
Mining can be part of the solution to the world's problems. Now, however, we are in a climate where people are becoming more socially responsible and interested in the content than they are buying. Partly because of this, many of the mobile device manufacturers have pledged to increase their recycling rates. It is a positive sign that the disposable society in which we live for decades is changing, and we hope this project will encourage more people to question their own behaviors.
As commented by the scientist, Apple itself periodically releases its environmental reports listing the materials used by the company and highlighting the advances in the use of socially responsible sources and the abandonment of materials harmful to the planet. So be it, then.
