E-waste is an untapped source of rare Earth materials
As the world battles through supply chain issues and geopolitical concerns disrupt the timely flow of materials, it’s becoming ever clearer that the supply of many rare earth metals and material is unsustainable. These materials are found in all kinds of products including those we dispose of everyday. E-waste is an excellent source of precious metals, and the recycling of e-waste needs to be dramatically ramped up.
The Royal Society of Chemistry in the UK (via bbc.com) is running a campaign aimed at raising awareness around the unsustainability of mining the materials that make up all the countless millions of pieces of consumer technology. These metals and materials often end up in landfill, creating potentially toxic contaminants. But this waste is also an untapped resource of the very materials that go into making it in the first place, hence the need for recycling.
Professor Tom Welton, president of the Royal Society of Chemistry, said that «Our tech consumption habits remain highly unsustainable and have left us at risk of exhausting the raw elements we need,» while «continuing to exacerbate environmental damage». According to a study cited by the BBC, the total amount of the world’s discarded electronics was 57 million tons in 2021 alone and growing at a rate of two million tons per year.
Some examples of materials that are at risk of running out over the coming decades include gallium, indium, yttrium and tantalum. They are used in everything from medical devices to semiconductors, batteries and solar panels. These are just a few examples of the things we take for granted and are products that are only going to increase in demand. It goes without saying that supplies of these materials are critical to ensuring a
