Link fu! I have not done one of these in a while; should be fun!

“ But lithium-ion batteries have long lives, says Hans Eric Melin, director of Circular Energy Storage. “Thirty percent of used EVs from the U.S. market are now in Russia, Ukraine, and Jordan, and the battery came along as a passenger on that journey,” Melin says.”

Used clothing used to go to Eastern Europe, but eventually went to Africa. Apparently, electric vehicles are at the Send to Eastern Europe stage.

Never mind being a locavore; the new thing will be recycling locally (this is mostly a joke): https://www.batteryresourcers.com/recycle

But probably not! Europe is trying to move towards a minimum recycled content quota (a la toilet paper or whatever) for batteries. The cars moving to Russia, with their batteries in them, to be driven even more years there before the battery is eventually reprocessed / refurbished / recycled, means that Russia would be where the recycling occurs, not in Eurozone. It’s an interesting analysis, followed up by more: since we have no idea what the chemical content of future batteries will be, we have no idea if recycled whatever that is will even exist in the future. If we mandate that a future battery be whatever percent lithium, and the total amount demanded by a future year is greater than the total of previous years, that is not going to happen! Melin is arguing that the proposed quota system is up against reuse (which is better than recycle anyway!) in another geographic area, expected technology changes and greater future production than now (lack of maturity of the ecosystem) and incumbent players better positioned to meet the quotas — but who are geographically Elsewhere. Compelling argument!

“ We’ve partnered to do all the recycling for Panasonic products that come from the Tesla “Gigafactory. This includes recycling production scrap, battery cells, and modules that do not pass validation.”

They talk a lot about closed loop and that’s awesome, but this paragraph suggests their focus is more post-industrial than post-consumer. Altho given what Melin said in the other article, probably makes sense. Melin, of Circular Energy Storage, is attempting to sell information about this business sector for beaucoup bux, as the middle-aged people used to say when they were kids.

I bought an Awair. I had been saying numerous times to numerous people how I really wanted there to be indoor air monitoring and regulation so we could tell when indoor air was meeting quality requirements for the before times (minimum) and ideally to a level with outdoor air, so that it would reduce airborne disease transmission risks (obviously covid now, but in general).

So I plugged it in, got the app, connected it to wifi and took a look at its readings in the kitchen. 854 on the CO2 reading. Not. What. I. Was. Hoping. For.! I contemplated my options, went over to the Nest and turned on the house fan. That has gotten it down to 783. It is a nice day. Perhaps I will open some windows or something.

I can easily see that this kind of thing could be a bit of a rabbit hole.

ETA: Speaking of it becoming a bit of a rabbit hole, I held it up to my mouth and breathed out on it a couple of times and popped the CO2 up to 1088. Hmmmm. ETAYA: Actually, there is some kind of smoothing or something, because it then popped up over 3000. I’m really starting to grasp the value of social distancing here. I mean, I totally got it anyway, but metrics!

ETA: Cooking next to this thing is HILARIOUS! Turn on the oven, air quality drops. Spray oil in a pan, air quality drops. This is fantastic. Also, wow, running the house fan makes a big difference on CO2 just always.
