Researchers are recycling old Nissan Leaf batteries using… bacteria?
Researchers at the University of Edinburgh in Scotland are investigating a way to recover the metallic content of EV batteries with bioengineered bacteria. The new method involves processing spent Nissan Leaf batteries into a “leachate” — a liquified battery slurry — and combining that slurry with said microbes.
The method isn’t described in a lot of detail, admittedly. Other than saying the bacteria used was selected and specifically engineered for the process, which occurs inside a bioreactor, we don’t really know how all this works. What is described is that the bacteria excrete the metallic content of the battery leachate as silt (read: the bacteria poop metal particles), which can then be isolated for use in whatever application it may be needed. Allegedly, this bioprocess yields silts of cobalt, manganese, nickel, and lithium.
The goal of the research at the Industrial Biotechnology Innovation Center is to scale up to a level that could conceivably be used to process a large number of batteries — though the question of cost scalability isn’t commented on (nor does that tend to be the main concern at this stage). Regardless, it’s fascinating research, and goes to show we’re probably still at the tip of the iceberg when it comes to creating a sustainable EV supply chain.
The use of bioengineering to break down materials isn’t a new concept — there’s similar research exploring bacteria to tackle the issue of microplastics and PFAS (non-degradable synthetics), though it’s all still in the very early stages. Now, it seems you can add batteries to that list.

Electrek’s take
Are bacteria the future of battery recycling? I mean, who really knows, but it goes to show the number of avenues we have left to explore. Unlike pulling carbon molecules belched from exhaust pipes and power plants back out of thin air, recycling batteries seems thoroughly feasible. And, eventually, it may even be cost-advantageous.
Recycling of EV batteries, in general, is a huge issue — Toyota recently signed a deal with Redwood Materials to commit to a more circular battery lifecycle. And given that there’s physically almost nothing lost when a battery is “used up,” creating this circular battery ecosystem should be a huge priority.
While advanced lithium extraction techniques are making the process less dirty, the cleanest raw material for your EV battery is one you didn’t have to pull out of the ground in the first place.

Rivian has posted a job listing for a steering engineer, specifically mentioning work on a future steer-by-wire system for the company.
Steer-by-wire is an automotive concept that has been around for a long time, but hasn’t yet reached mass adoption. The idea is to replace (or supplement) mechanical linkages between the steering wheel and the wheels with electronic actuators instead.
There are a number of potential benefits to this, like allowing more customizability or adaptability to a steering system, reducing mechanical complexity, or adding speed-sensitive variable steering ratios.
Although there are also disadvantages, like a reduction in steering feel (although, since most cars are moving to electronic power steering, that was already gone anyway).
But few cars have implemented steer-by-wire systems, or at least not fully committed to them, given that mechanical steering racks are a relatively solved problem and the general inertia of the car industry which would rather stick with a solution they know than switch to something better (haven’t we here, at this EV publication, heard *that* one before…). There’s also the matter of regulations, which have often been written to require mechanical steering systems, and may need updating to allow for steer by wire.
But, steer by wire made it into mass production with the release of the Tesla Cybertruck. This was big news when Tesla committed to this – at the time, it was the only thing on the road to exclusively use a steer by wire system, though there are other cars with partial steer by wire (for example, mechanical front wheel steering, and steer by wire rear-wheel steering).
But it seems to have opened the floodgates, as a number of other companies are working on or have since released steer by wire systems (Lexus, for example).
And now, it looks like Rivian is one of those companies – though we don’t know if it’s for the front or rear.
The company posted a job listing for “Sr. Staff Technical Program Manager, Steering Actuator System,” based at its Irvine, CA headquarters (spotted by Rivianforums). This wouldn’t be so exceptional, except that the job posting also specifically points out that “you’ll have full cradle-to-grave ownership of the SBW subsystem.”
So – we know they’re working on steer by wire, to some extent.
But a few other EVs, particularly large EVs like the Rivian R1 platform is, use steer by wire just for the rear wheels – for example the Hummer EV and Rolls-Royce Spectre. These systems are particularly helpful for giant vehicles, because it allows them to be more nimble and make turns that otherwise would require a lot more… negotiation in a giant land yacht.
So it’s possible that Rivian is only working on rear wheel steer by wire here, but we’d like to think there’s a chance it’s working on steer by wire for the full vehicle.
We also don’t know if this would show up on all of Rivian’s vehicles, or only on certain models – the R2 and R3 are in development, and the R1 just got a big refresh. But, perhaps even more interestingly (and very speculatively), VW has invested heavily in Rivian for technology help, so we wonder if we might end up seeing this in VW group vehicles, or Scout vehicles eventually…
