‘Endangered’ elements used to make mobile phones are running out quickly, scientists warn

Vital chemical elements have been included on an “endangered list” because they are being thrown away in mobile phones at such a high rate.

Scientists have warned some of the substances used to make phones are becoming increasingly scarce due to limited supplies, their location in conflict zones and the lack of recycling.

To tackle this problem, they say people should avoid changing their phones every few years.

Researchers have developed a periodic table highlighting the scarcity of Earth’s 90 naturally occurring elements, many of which are used in the production of devices like phones and TVs.

The work was carried out as part of a project by the European Chemical Society (EuChemS), which represents more than 160,000 chemists from more than 40 member societies and other chemistry-related organisations.

The modernised periodic table was designed to mark the 150th anniversary of its creation in 1869.

It is estimated that about 10 million smartphones are discarded or replaced every month in the EU alone.

The bright colours of the display are produced by small amounts of rare earth elements, including yttrium, terbium and dysprosium.

“It is astonishing that everything in the world is made from just 90 building blocks, the 90 naturally occurring chemical elements,” said Professor David Cole-Hamilton, a chemist at the University of St Andrews.

“There is a finite amount of each and we are using some so fast that they will be dissipated around the world in less than 100 years,” he said.

“Many of these elements are endangered, so should you really change your phone every two years?”

The periodic table will be launched at the European Parliament on Tuesday by Labour MEPs Catherine Stihler and Clare Moody.

The event will also highlight the discovery of the oldest-known wallchart of the periodic table, discovered last year at the University of St Andrews.

Ms Stihler said: “As we mark the 150th anniversary of the periodic table, it’s fascinating to see it updated for the 21st century.

“It’s also deeply worrying to see how many elements are on the endangered list, including those which make up mobile phones.

“It is a lesson to us all to care for the world around us, as these naturally occurring elements won’t last forever unless we increase global recycling rates and governments introduce a genuine circular economy.”

Besides the problem of depleted reserves, many have raised concerns about the mines in which some elements used to make smartphones are extracted.

Extracting rare earth elements in China is known to have an enormous environmental impact, while cobalt mines in the Democratic Republic of the Congo have been highlighted as a major human rights concern.
