Cell Phone Pollution: What's The Harm?

Smartphones are contributing to global warming and climate change throughout their life cycle, from production to disposal. The raw materials needed to produce a smartphone, including gold, cobalt, lithium, and other heavy metals, require energy-intensive mining, and their extraction often causes significant environmental pollution. The mass production of smartphones in mega factories also greatly contributes to climate change, with 85-95% of a smartphone's overall carbon footprint produced during the manufacturing process. The rising market of refurbished phones might offer some hope, but the multi-function devices that have become a permanent fixture in our palms leave a trail of environmental pollution and a largely overlooked carbon footprint.

Mining for raw materials

The raw materials needed to produce a smartphone, including gold, cobalt, lithium, and other heavy metals, require energy-intensive mining, and their extraction often causes significant environmental pollution. The mining of gold, for example, has led to deforestation, water contamination, and violence against indigenous people in Brazil, as well as the destruction of the Amazon rainforest in Venezuela. Water bodies located near copper mines, with the largest ones found mainly in Chile and Peru, can turn reddish after being contaminated, affecting fish, wildlife, and farmland.

Silicone and plastic take up about half of the materials used in a smartphone, while iron, aluminium, and copper are the most common metals. The extraction of these metals often involves metal extraction, shipping, and production, all of which contribute to a smartphone's carbon footprint.

The mass production of smartphones in mega factories greatly contributes to climate change, with 85%-95% of a smartphone’s overall carbon footprint produced during the production process. The batteries, integrated circuits, speakers, and screens used to manufacture smartphones are mass-produced, creating carbon footprints, heat emissions, and environmental pollution.

While no production is completely carbon-free, the market for refurbished, used smartphones or those produced from recycled materials is growing. Over 251 million used smartphones were shipped worldwide in 2021, and by 2027, 200 million more shipments are predicted, according to Statista.

Manufacturing process

The manufacturing process of smartphones is a major contributor to environmental pollution. The production of smartphones accounts for 85-95% of a smartphone's overall carbon footprint, with the mass production of components such as batteries, integrated circuits, speakers, and screens creating carbon footprints, heat emissions, and pollution. The extraction of raw materials, including gold, cobalt, lithium, and other heavy metals, requires energy-intensive mining, which often leads to significant environmental pollution, deforestation, and water contamination.

The manufacturing process of smartphones involves the use of a wide range of chemicals and materials. Silicone and plastic make up about half of the materials used, while iron, aluminium, and copper are the most common metals. The production and shipping of these materials also contribute to a smartphone's carbon footprint.

The mining of gold, a precious metal used in smartphone manufacturing, has had severe environmental and social impacts. In Brazil, gold mining has led to deforestation, water contamination, and violence against indigenous people. Similarly, copper mining in Chile and Peru has contaminated nearby water bodies, turning them reddish and affecting fish, wildlife, and farmland.

The mass production of smartphones in mega factories exacerbates environmental crises, including deforestation and water pollution. The high demand for smartphones, with over half of the world's population owning one, has led to increased production and a largely overlooked carbon footprint. While the market for refurbished and recycled smartphones is growing, the challenges of ensuring proper recycling and reducing pollution during the manufacturing process remain.

Environmental pollution

Smartphones contribute to environmental pollution and climate change throughout their life cycle, from production to disposal. The raw materials needed to produce a smartphone, including gold, cobalt, lithium, and other heavy metals, require energy-intensive mining, and their extraction often causes significant environmental pollution. The mass production of smartphones in mega factories also greatly contributes to climate change, with 85-95% of a smartphone's overall carbon footprint produced during the manufacturing process. The manufacturing process of a smartphone accounts for about 85% of its carbon footprint, making it the most damaging device to the environment. These emissions mainly come from metal extraction, shipping and production. The mining of gold has led to deforestation, water contamination and violence against indigenous people in Brazil, as well as to the destruction of the Amazon rainforest in Venezuela. Water bodies located in the vicinity of copper mines - with the largest ones found mainly in Chile and Peru - can turn reddish after being contaminated. It also affects fish, wildlife and farmland. In China’s Inner Mongolia, a lake is brimming with electronic waste, such as smartphones, as the country produces most of the world’s rare earth metals.

The challenges in the fight against pollution from smartphones often revolve around the recycling of phone materials. Ensuring that people give up their old phones for recycling, making sure that smartphones do go forward for recycling rather than ending up in landfill sites or as e-waste, being able to successfully take smartphones apart to recover their valuable components such as copper, gold, silver, lithium and cobalt, and supporting smartphone recycling companies are all important steps in reducing smartphone pollution. While no production is completely carbon-free, the market of refurbished, used smartphones or those produced out of recycled materials is emerging: over 251 million used smartphones were shipped across the world in 2021, and by 2027, 200 million more shipments are predicted, according to Statista.
