There’s a large Acer tree in the Badger’s garden with masses of delicate leaves which rustle sweetly when there’s a hint of breeze. In the Summer it’s a great place to sit in the shade under its branches with a cold beer. In the UK’s heatwave that’s exactly what the Badger did to escape the sun’s rays, read, track online interests, and cogitate about life. He’s probably drunk more cold beer than prudent but chilling out in this way allows the mind to be stimulated by something you read, at least that’s the case with the Badger. You can predict neither the trigger in advance, nor how your thoughts will develop to a conclusion once they’re triggered. So, what caught the Badger’s eye and triggered the stream of thought that prompted the writing of this post? It was reading that an interdisciplinary team of scientists has found a new and sustainable way to recover gold from e-waste (see here and here).
The Badger’s interest was piqued because of his metals/materials research background prior to a career in IT during which a latent interest in metals/materials never entirely disappeared. Gold, recovering it from e-waste, and e-waste itself, are fascinating topics given this metal’s unique properties. The total amount of gold ever mined makes just a 22-metre sided cube, and tiny quantities are used in smartphones, computers, and most other electronic devices. E-waste is any electrical or electronic equipment that’s been discarded, working or not. We all have some – perhaps an old MP3 player, smartphone, or tablet – somewhere in a drawer or cupboard. E-waste volumes, containing gold and other important elements, are growing but less than 25% of it is collected and recycled. A new, sustainable, cheaper, and less hazardous way of recovering gold from it is an important development, especially if we stop hoarding our old devices in the first place!
Once triggered, where did the Badger’s thoughts end up? They meandered but concluded something about innovation, a subject that seems to be dominated in the mainstream by AI and new services in the virtual digital world. But here’s the point. None of this virtual digital innovation could exist without underlying ‘true physical innovation’ in the world of metals and materials. Without innovation in the science, extraction, processing, manufacturing, and recycling of condensed matter none of the electronic devices we rely on in the online digital world of today and tomorrow would exist. Youngsters looking for a stable and fertile career path should thus consider the physics and chemistry of metals/materials because the world today and in the future depends more and more on innovation in this field. One thing, however, is a certainty. You never know what will trigger your thoughts and where they will take you if you relax with a cold beer in the shade under a tree in a heatwave….
