What can an individual do to make the most sustainable choice when buying a new laptop or smartphone? Don’t buy. Hold on to your device for one more year. “As an individual, there is very little you can do,” scientist Josh Lepawsky explains. “I know that that can be a depressing thing. But if you think about going into an electronics s... Read More »
“One of the best places for environmental chemists to look for previously unknown chemical pollutants is not in ‘the environment’ or ‘Nature’ but in the residues of previously manufactured commodities, particularly discarded electronics,” scientist Josh Lepawsky has stated. “It can be somewhat amazing to learn that we have very little ...

They say that we must mine our way to a ‘green’ and ‘renewable’ future. To save the world we must massively increase mining so that by 2050, we will be mining a Mount Everest every year. Every single year, mining out of the Earth the mass of a Mount Everest, 90% of which immediately becomes waste. “I have stood on the edge of a mine in... Read More »
The Irish government has a document on data centers that reads more like the talking points of an industry lobbyist than a carefully thought-through analysis of the true worth and costs of data centers. Below is an analysis of the claimed benefits. Benefit: data centre technology supports a wide range of sectors in Ireland.Vague and me... Read More »
The manufacturing of our digital products has a huge, toxic impact on the environment. As computer chips become smaller and more complex, their demand for water rises substantially. A typical computer chip making process requires that each wafer has to be rinsed with water more than 30 times. The result is that to make a smartphone can c... Read More »
“There’s this long-standing tendency to think about and talk about and market digital to occur or happen in a placeless place,” Josh Lepawsky told me. “We use words like ‘virtual’. That isn’t an accident. It has been part of the conversation around the industries that design, make and build electronics devices really since their inceptio... Read More »
“Increasing data size shrinks confidence intervals but magnifies the effect of survey bias: an instance of the Big Data Paradox,” a study in Nature magazine has stated. What this means is that Big Data can give you great confidence in being entirely wrong. Organizations are suffering from data overload. And the problem will get exponen... Read More »
Why are data centers so super-secretive? “My hypothesis is that data centers are facing more and more opposition worldwide by local communities because these communities are starting to understand that most of the positive impacts of a data center will not be seen by the local community,” Gauthier Roussilhe, an environmental footprint sp...

To make a smartphone requires 50-60 materials and 1,000 substances: 25% silicon, 23% plastic, 20% iron, 14% aluminum, 7% copper, 6% lead, 2% zinc, 1% tin. 90 kg of stone, gravel, and tailings are mined for every smartphone. “In Brazil and Minas, it is the ore above everything and everyone,” says anthropologist Andréa Zhouri. She explai... Read More »
As the race for minerals frantically speeds up, driven by the ‘clean’ and ‘green’ energy revolution, the minerals become harder and harder to retrieve, and the percentage of waste to useful mineral grows and grows. “Over the past 40 years, ore grades—the concentration of the metal or mineral of value—have declined on average by half for ...
