The Journey of an Old Phone – From Waste to New Resource
In the era of technology, millions of mobile phones are discarded each year as users upgrade to newer versions. Few realize that behind these seemingly useless devices lies a hidden treasure of resources that can be reborn, helping to reduce the burden of electronic waste and protect the environment.
E-waste – A Global Threat
According to a United Nations report, in 2023 the world generated more than 60 million tons of e-waste, including millions of discarded phones. These products contain heavy metals and toxic chemicals such as lead, mercury, and cadmium. If not properly processed, they can seep into soil and water sources, causing severe harm to human health and ecosystems.
Old Phones – A Valuable Resource
Contrary to the image of “waste,” an old phone is actually a mobile mine of resources. Inside, it contains gold, silver, copper, cobalt, and rare earth elements, materials that are both valuable and scarce worldwide. Recycling just 1 million smartphones can yield nearly 35 kg of gold, 350 kg of silver, and tens of tons of copper.
The Journey of Renewal
The recycling process begins with collection and sorting. Devices are then dismantled to separate screens, batteries, circuit boards, and casings. Lithium-ion batteries are processed for reuse or converted into new materials, while electronic circuit boards are shredded and refined to extract precious metals. Plastic, glass, and metal casings can also be recycled into other industrial products.
A Sustainable Path Forward
Many countries and businesses have launched programs to collect old phones for recycling. In Vietnam, some electronics brands and supermarkets have placed collection bins to encourage people to safely dispose of old devices. This is a vital step toward building a circular resource system, reducing raw mineral extraction, and moving toward a green economy.
A Call to Action
Every old phone we discard can become a “piece” of a sustainable future. The journey of turning waste into resources requires not only the efforts of businesses but also awareness from each individual. Instead of leaving them forgotten in a drawer or carelessly throwing them away, let’s give them a chance to be reborn because from waste, they can create new value for life.
