Tesla’s former CTO JB Straubel is ramping up his stealthy recycling business
When former CTO JB Straubel announced that he would be taking more of an advisory role in Tesla and that he would be stepping down from his day-to-day responsibilities as the electric car maker’s Chief Technology Officer, he provided a firm assurance that he was not “disappearing” from the company. The ongoing growth of a stealthy recycling startup registered under Straubel’s name suggests that his words back in the Q2 2019 earnings call were no fluke.
JB Straubel is known for being the backbone of Tesla’s battery tech. One of the most notable photos in Tesla history quite literally depicts Straubel assembling a battery module by hand. It would not be a stretch to state that innovations in Tesla Energy and at Gigafactory 1 in Nevada have been possible primarily due to Straubel’s work and genius. Yet, despite Tesla’s batteries being pretty much the best in the market, Straubel has noted that there is something still missing from the puzzle: closed loop battery recycling.
During the 2018 Annual Shareholders Meeting, Straubel addressed an inquiry from an investor about Tesla’s approach to battery waste. The former CTO’s response was brief, stating that Tesla’s priorities lie in recycling its batteries, thereby preventing the company’s old cells from ending up in landfills. Eventually, Straubel stated, Tesla wants to develop a closed loop, using the same materials from batteries that it recycles to create new packs.

“Tesla will absolutely recycle, and we do recycle, all of our spent cells, modules and battery packs. So the discussion about is this waste ending up in landfills is not correct. We would not do that, these are valuable materials. In addition, it’s just the right thing to do. We have current partner companies– on every major continent where we have cars operating– that we work with to do this today. And in addition, we’re developing internally more processes, and we’re doing R&D on how we can improve this recycling process to get more of the active materials back. Ultimately what we want is a closed loop, right, at the Gigafactories that reuses the same, recycled materials,” he said.
As noted by Tesla investor-enthusiast Galileo Russell of YouTube’s HyperChange channel, JB Straubel just so happens to have a startup that appears to address the very same point that he emphasized during the 2018 Shareholder Meeting. Registered to do business in Nevada, Straubel’s startup, called Redwood Materials, is focused on next-generation recycling technologies. A look at Redwood’s bare-bones official website shows a statement that goes very well with Tesla’s mission.
“Advancing sustainability through research and development, engineering, and operational excellence for next generation recycling processes and programs.”
Redwood Materials lists Straubel and fellow Tesla alumni Andrew Stevenson, who served under the former CTO as Head of Special Projects, as executive officers of the stealthy recycling startup. Filings for the recycling company have also shown that Redwood received $2 million worth of investments. Quite interestingly, Straubel provided a response to CNBC last year when the news outlet published a report on the startup, stating that Redwood, at least at that point, was not doing any direct business with Tesla.

“Redwood is not currently doing any business with Tesla and our expansion to Nevada is unrelated to Tesla or to the Gigafactory directly. Northern Nevada has a welcoming business environment, a growing technology presence and gives us a strong foundation for aggressive future growth,” he said.
It’s been over a year since Straubel gave his response to CNBC, and a lot has happened since then. Tesla’s batteries have improved, and if the Cybertruck’s starting price is any indication, the electric car maker appears to have lowered its battery production costs even further. Straubel has also transitioned to an advisory role in Tesla, presumably to focus on other projects. One of these projects could very well be the work being done by Redwood, which just happens to be completely compatible with Tesla’s electric cars and energy storage systems.
The signs definitely are there, and if the HyperChange host’s speculations prove right, it would mean that Tesla could be the auto industry’s first company that can achieve true closed loop battery recycling, a thing that was once considered as the holy grail for electric car production.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”

Tesla FSD (Supervised) blows away French journalist after test ride
Cadot described FSD as “mind-blowing,” both for the safety of the vehicle’s driving and the “humanity” of its driving behaviors.
Tesla’s Full Self-Driving (Supervised) seems to be making waves in Europe, with French tech journalist Julien Cadot recently sharing a positive first-hand experience from a supervised test drive in France.
Cadot, who tested the system for Numerama after eight years of anticipation since early Autopilot trials, described FSD as “mind-blowing,” both for the safety of the vehicle’s driving and the “humanity” of its driving behaviors.
Julien Cadot’s FSD test in France
Cadot announced his upcoming test on X, writing in French: “I’m going to test Tesla’s FSD for Numerama in France. 8 years I’ve been waiting to relive the sensations of our very first contact with the unbridled Autopilot of the 2016s.” He followed up shortly after with an initial reaction, writing: “I don’t want to spoil too much because as media we were allowed to film everything and I have a huge video coming… But: it’s mind-blowing! Both for safety and for the ‘humanity’ of the choices.”
His later posts detailed FSD’s specific maneuvers that he found particularly compelling. These include the vehicle safely overtaking a delivery truck by inches, something Cadot said he personally would avoid to protect his rims, but FSD handled flawlessly. He also praised FSD’s cyclist overtakes, as the system always maintained the required 1.5-meter distance by encroaching on the opposite lane when clear. Ultimately, Cadot noted FSD’s decision-making prioritized safety and advancement, which is pretty remarkable.
FSD’s ‘human’ edge over Autopilot
When asked if FSD felt light-years ahead of standard Autopilot, Cadot replied: “It’s incomparable, it’s not the same language.” He elaborated on scenarios like bypassing a parked delivery truck across a solid white line, where FSD assessed safety and proceeded just as a human driver might, rather than halting indefinitely. This “humanity” impressed Cadot the most, as it allowed FSD to fluidly navigate real-world chaos like urban Paris traffic.
Tesla is currently hard at work pushing for the rollout of FSD to several European countries. Recent reports have revealed that Tesla has received approval to operate 19 FSD test vehicles on Spain’s roads, though this number could increase as the program develops. As per the Dirección General de Tráfico (DGT), Tesla would be able to operate its FSD fleet on any national route across Spain. Recent job openings also hint at Tesla starting FSD tests in Austria. Apart from this, the company is also holding FSD demonstrations in Germany, France, and Italy.

Tesla Optimus shows off its newest capability as progress accelerates
Tesla Optimus showed off its newest capability as progress on the project continues to accelerate toward an ultimate goal of mass production in the coming years.
Tesla is still developing Optimus and preparing for the first stages of mass production, where units would be sold and shipped to customers. CEO Elon Musk has always marketed the humanoid robot as the biggest product in history, even outside of Tesla, but of all time.
He believes it will eliminate the need to manually perform monotonous tasks, like cleaning, mowing the lawn, and folding laundry.
However, lately, Musk has revealed even bigger plans for Optimus, including the ability to relieve humans of work entirely within the next 20 years.

Optimus has also made several public appearances lately, including one at the Neural Information Processing Systems, or NeurIPS Conference. Some spectators shared videos of Optimus’s charging rig, as well as its movements and capabilities, most interestingly, the hand:

The hand, forearm, and fingers have been one of the most evident challenges for Tesla in recent times, especially as it continues to work on its 3rd Generation iteration of Optimus.
Musk said during the Q3 Earnings Call:
“I don’t want to downplay the difficulty, but it’s an incredibly difficult thing, especially to create a hand that is as dexterous and capable as the human hand, which is incredible. The human hand is an incredible thing. The more you study the human hand, the more incredible you realize it is, and why you need four fingers and a thumb, why the fingers have certain degrees of freedom, why the various muscles are of different strengths, and fingers are of different lengths. It turns out that those are all there for a reason.”
The interesting part of the Optimus program so far is the fact that Tesla has made a lot of progress with other portions of the project, like movement, for example, which appears to have come a long way.
However, without a functional hand and fingers, Optimus could be rendered relatively useless, so it is evident that it has to figure this crucial part out first.
