Former Tesla CTO’s battery recycling startup secures funding from Amazon
Redwood Materials, the battery recycling startup founded by former Tesla CTO JB Straubel, recently secured some funding from Amazon as part of the e-commerce giant’s efforts to reduce its emissions. Redwood is one of five companies that Amazon is investing in as part of its Climate Pledge Fund, which was announced last year and expected to cost about $2 billion.
In a statement about the five companies that received funding, Amazon CEO Jeff Bezos stated that firms like Redwood are “channeling their entrepreneurial energy into helping Amazon and other companies reach net zero by 2040 and keep the planet safer for future generations.” Amazon, for its part, appears to be interested in Redwood’s recycling technology, which could allow materials like lithium, cobalt, and nickel to be extracted from old smartphones and other consumer devices.
Redwood was founded by the former Tesla CTO in 2017 after seeing that the global shift to electric vehicles will likely cause unnecessary environmental damage from a surge in mining. Such a scenario would only happen, however, if there is no recycling system in place that would allow EV producers to reuse the materials that have already been used in their cars’ batteries. Speaking with the Financial Times, Straubel shared his vision for the transportation sector, which involves the mass adoption of EVs and a closed-loop battery recycling system.
“(My vision is a) world where all of the transportation is done by electric vehicles and we have batteries powering a sustainable world. And all of those batteries are able to be recycled and remanufactured many, many times so that we can have a nearly closed-loop,” Straubel said.
This same concept stands just as true in the consumer electronics sector, according to the former Tesla CTO. Straubel remarked that while batteries are bound to degrade with repeated use, the underlying elements that comprise them remain sealed from the environment. This meant that the batteries’ materials, most of which are very valuable, could be broken down and repurposed once more. If this is accomplished, the former Tesla executive believes that mining would not be as necessary anymore.
“There are a phenomenal amount of cell phones in the world that currently are being discarded as trash or thrown into a landfill. It’s a massive, untapped resource. If we can recover 98 or 99% of those materials and reuse them, we don’t need very much new material to keep that whole process running… Even though the battery is internally degraded, all of the same materials are still in there — all of the same atoms of lithium, nickel, and cobalt. You can still harness all of those same materials, but they need to be reprocessed and brought back to a state where they could be used again and built into a new battery,” Straubel remarked.
The exact amount of funding that Redwood Materials has acquired from Amazon has not been disclosed by either company, through the former Tesla executive noted that there was a potential for “partnership on a number of different levels” between the recycling startup and the e-commerce giant. One of these levels may include aiding Amazon in building and developing an end-of-life process for consumer electronics that are sold through its e-commerce platform so that the devices and their components could be reused.

Redwood Materials has remained mostly in stealth mode since its founding, though signs have emerged that the company may be part of Tesla’s efforts to develop its own battery recycling processes. One of these involves an existing partnership with Panasonic to reclaim the scrap that is generated from the battery cells currently produced at Tesla’s Gigafactory Nevada facility. Reports have indicated that Panasonic initially started a trial run with Redwood to reclaim more than 400 pounds of scrap from Giga Nevada, and the results were so successful that the Japanese firm raised its contract to 2 tons not long after.
Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled

Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
