Sustainable Tech and Products: What You Can Do
Tech is "sustainable" if it can be "sustained" - kept running - for a long time. If you have to replace your smartphone or your Chromebook every 2-3 years because the manufacturer stops issuing security updates (you daren't use it in public if the "security update" is more than a month or two old), that's not sustainable.
Stuff in general is "sustainable" if it can be manufactured, used, and then either reused or recycled, or if its processing reduces the resources that were previously consumed.
In one sense I've always been about sustainability. My second car was a used Mazda R100, little-known but actually the first production car in history powered by a Wankel rotary engine. It had other pioneering features, like a sophisticated pollution control system. I saved it from the junk yard, buying it cheaply because the rotor seals (analogous to piston rings on a conventional gasoline engine) were shot, and I think the dealer had to pull the engine out to replace those. If I recall correctly, I paid more for the repair than I had for the car.
I drove the thing to and from work. A year rolled by. One morning the car made a horrible new screeching sound when I tried to start it. Quick examination under the hood showed that one of the pulleys connected to a large V-belt had ceased to operate. My dad was a jack-of-all-trades do-it-yourselfer (DIY) and a Civil Engineeer. Partly from him, I had inherited enough mechanical skills to dismount what turned out to be the "A.I.R." pump from the pollution control system. Upon dismantling that, I found that it had rotors/gaskets, rather like the ones inside the engine, but made of plastic. One had broken and jammed sideways, preventing the pump from turning. I phoned the Mazda dealer in Toronto, and asked him how much to replace these gaskets. He said, quite seriously, "Oh, we don't replace those. We just replace the whole pump." I guess sustainability was not a thing back then. He quoted me a price of $300 just for the part (in 1970's dollars; that would be about a kilobuck today). I laughed and hung up. The same $300 instead bought me a Unimat, a miniature machine shop-in-a-box. I then spent ONE DOLLAR on a bakelite plastic box which I cut up, and used the Unimat to mill down the sides into replacement rotor gaskets. These worked for years until I retired the car.
Nearly half a century later, I still have the Unimat. And it still works, a testament to 1970's quality Austrian engineering and manufacturing.
Of course, these days, when I do have to drive, I drive an electric car. The science says these are way better, despite what the haters say.
Megatons of electronic waste go into landfills every year, because phone makers need you to scrap a perfectly viable phone, so they can sell you a new one, every few years. They do this both by witholding software "security updates", and by making new phones with more new frilly features every year. Some companies are bucking this trend.
Laptop and Desktop Computers
Kick the battery habit
Gazillions of alkaline battery cells from flashlights, radios, toys, etc., wind up in landfill each year. This doesn't have to happen:
Companies that Repair/Repurpose used equipment
Supporting Old TechThere are lots of companies/projects that provide updated support for hardware that is abandoned by the original vendor. Just a few examples:
Re-using used stuff saves (money and the environment)
