The production and end-of-life disposal of our smartphones, computers and other modern tech have a dramatic impact on the environment, which can often be overlooked when compared to other environmental issues. Half of the carbon emissions from the digital sector (making up 4% of global emissions) come from the production of devices like these, and buying them refurbished, while not a perfect solution, can help to significantly limit their environmental impact. 

Rare earths, gold mines, plastic… the manufacturing of tech products and its environmental impact.

Computer and smartphone factories are huge guzzlers of gold, silver and many types of metals and rare earths. The extraction of these minerals, which are essential for the production of the components of our devices, has a sizable impact on the environment and ecosystems, not to mention the often-horrendous human conditions in which mines are operated. On average, 130 grams of minerals and rare metals go directly into a smartphone. However, the overall damage and impact is far broader - an average of 44 kg of rock has to be extracted and destroyed to obtain these materials. In the end, the manufacture of a computer actually ends up using an average of almost 200 kg of raw materials. The exploitation of the mines from which the materials are extracted also has a particularly disastrous impact on water resources. Gold production, for example, releases cyanide and mercury, which end up in rivers. Plus, in order to produce one ton of neodymium (the rare material that makes our phones vibrate), 75,000 litres of water are contaminated with toxic substances. 

The consequences of the production of these objects on freshwater reserves don't stop there either unfortunately. It takes on average 1,000 litres of fresh water to produce a smartphone and 1,500 litres to produce a computer. These are not negligible quantities in the context of increasing water stress in many parts of the world.

Last, but certainly not least damaging, plastics. Derived from fossil fuels – plastics are an important component of electronics and household appliances, with well-known environmental consequences. The average smartphone is made up of around 40% plastic, often mixed with other chemicals that make them only partially recyclable. 

Electronic waste: a growing problem, aggravated by planned obsolescence.

Producing a computer or a telephone—from the manufacture of its components to the time it leaves the factory - has a huge impact on the environment. But the end-of-life disposal of these devices also poses a major problem. 

We hear more and more about the issue of waste electrical and electronic equipment, and the difficulty of collecting and recycling it. With good reason too! With more than 50 million tonnes produced in 2019 (representing more than 6 tonnes of e-waste produced per hour), our old tech equipment is a major source of waste worldwide. This trend is also unfortunately exponential: meaning we should reach 74 million tons in 2030. 

Only 17.4% of this waste is properly collected and recycled, the rest is burnt or dumped in landfills. 

Many countries dispose of this waste, loaded with toxic substances (arsenic, mercury, cadmium, etc.), by sending it to West Africa or Asia, where illegal landfills are multiplying. There, workers put their lives at risk by dismantling and burning these devices without protection in order to recover the materials, for a price lower than the cost of mining them. These landfills have disastrous consequences for both human and environmental health.

Refurbishing as an alternative to the overproduction of appliances and waste.

Fortunately, there are things we can do to reduce the environmental impact of our phones and computers. Obsolescence is not inevitable!

The first thing to do is to avoid buying anything at all when you can keep your existing devices. And when a purchase is necessary,  opt for a second-hand or refurbished device instead of buying new.

Buying a refurbished computer or smartphone means avoiding both the environmental footprint of its production and its destruction.

Of course, the refurbishing industry itself still has an impact on the environment: there is the transport to the refurbisher and sometimes, the need to replace certain parts (a battery or a screen for example). That being said, this impact is, on average, 3 times less than that of the production of a new device.
