Tesla’s battery genius may hold the key to a closed-loop recycling endgame
Last year, a proverbial bomb dropped on Tesla after CTO and co-founder JB Straubel announced that he was transitioning into an advisor role and stepping away from his day-to-day duties in the company. While Straubel assured investors that he was not “disappearing” from Tesla in his final earnings call, he did stay notably under the radar following his departure. But as the date for the electric car maker’s Battery Day draws closer, it appears that some pieces are slowly falling into place suggesting that JB Straubel’s company, Redwood Materials, and Tesla, may be coming together at a key junction.
To state that JB Straubel was the backbone of Tesla’s industry-leading battery tech is no understatement. Much of the company’s breakthroughs in its battery-related efforts, such as the construction of Gigafactory Nevada, would not have been possible without Straubel’s genius. In fact, so notable were his contributions to Tesla’s battery tech in the company’s early days that he was eventually considered as a co-founder of the electric car maker.
But even during his last years at Tesla, Straubel has remarked that one key aspect remains missing from the EV transition — closed-loop battery recycling. Battery electric vehicles are great in the way that they are zero-emissions, after all, but disposing of their batteries at their end-of-life presents notable challenges under closed-loop recycling is developed. “Ultimately what we want is a closed-loop, right, at the Gigafactories that reuses the same, recycled materials,” he remarked at Tesla’s 2018 Annual Shareholders Meeting.
Prior to his departure from his day-to-day duties at Tesla, reports emerged stating that Straubel had founded a stealthy battery recycling startup called Redwood Materials. Interestingly enough, Redwood centered its operations in Nevada, the same state that hosts Tesla’s biggest battery facility to date, Gigafactory 1. When reports about Redwood initially emerged in 2018, however, Straubel was quick to note that his recycling startup’s operations are “unrelated to Tesla or to the Gigafactory directly.”
A recent report from The Wall Street Journal has now revealed some notable details that may explain some aspects of Straubel’s statement back in 2018. According to the publication, Redwood has already convinced Panasonic, Tesla’s battery partner at Gigafactory Nevada, to utilize Redwood’s technology to reclaim scrap from its operations in the facility. Panasonic reportedly started with a trial run that involved Redwood reclaiming more than 400 pounds of scrap from its Giga Nevada operations. The Japanese firm appears to have been satisfied with Redwood’s results in the trial run, as Panasonic reportedly upped its contract with the startup to 2 tons not long after.
Today, the Journal stated that all of the scrap coming from Panasonic’s side of Gigafactory Nevada’s battery production activities are being shipped to Redwood Materials for recycling. In a way, Redwood’s partnership with Panasonic seems to fit Straubel’s statement back in 2018, when he noted that his startup has no direct relation to Tesla’s operations. That being said, it is evident that Redwood’s tech is a notable step forward towards JB Straubel’s vision of a closed-loop battery recycling system.
Straubel’s plans for Redwood are ambitious, as he is looking to develop a recycling process that is so efficient that batteries coming from retired electric vehicles and energy storage units could be quickly stripped down, recycled for their core materials, and used to rebuild new batteries. With such a system in place, a closed-loop is created, and hardly any materials are lost. It’s a lofty goal, but it does hint at Straubel’s understated determination that made him such a powerful background force in Tesla.
Interestingly enough, Tesla’s new Impact Report specifically includes a section about closed-loop battery recycling. According to the electric car maker, such a setup at Gigafactory Nevada “presents a compelling solution to move energy supply away from the fossil-fuel based practice of take, make and burn, to a more circular model of recycling end-of-life batteries for reuse over and over again. From an economic perspective, we expect to recognize significant savings over the long term, as the costs associated with large-scale battery material recovery and recycling will be far lower than purchasing and transporting new materials.”
It remains to be seen if JB Straubel’s Redwood Materials and Tesla are indeed working together to recycle batteries from Gigafactory 1 and perhaps even the electric car maker’s own Roadrunner program, but despite the lack of confirmation for now, one thing is certain. One of the brightest minds in Tesla, who is arguably the genius behind the company’s battery tech and initiatives, has started a thriving company that fills in the crucial gap of battery recycling. And with such a key innovation at its doorstep, it appears out of character for Tesla to simply ignore the opportunities presented by Redwood Materials and its battery recycling technologies.

Tesla Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Inside Tesla’s secretive $10 Billion “Project Crystal Sun” filing
Tesla filed for a $10.1 billion Fort Bend solar factory, but the site isn’t confirmed.
Tesla has filed paperwork in Texas for a second massive manufacturing project in the same week it locked down its chip fabrication site, this time for a $10.1 billion solar cell plant in Fort Bend County. The filing, submitted July 22 under the state’s Jobs, Energy, Technology and Innovation Act and first surfaced by Sawyer Merritt on X, lists an internal project name of “Project Crystal Sun” and targets a site off FM 762 and FM 1994 near Richmond, about 40 minutes outside Houston.
Tesla is planning to build a $10.1 billion vertically integrated solar cell manufacturing facility in Fort Bend County, Texas, about 40 minutes from Houston, according to a new public application filing.

The application, prepared by Kroll Tax Services on Tesla’s behalf, spans five parcels totaling roughly 3,000 acres within the Lamar Consolidated Independent School District. Tesla wants a 10 year property tax limitation in exchange for the investment, split as $1.5 billion in real property and $8.6 billion in equipment and personal property. The company projects 9,712 permanent jobs once the plant reaches full operation, with 1,147 peak construction jobs during a build window running from this year through 2028 and commercial operations targeted for the first quarter of 2029.
Tesla is not fully committed to Fort Bend County yet. The filing states the company is weighing the site against an unnamed out of state alternative, and frames the tax abatement as what would make Texas competitive against that option. If the district and county decline the incentive, Tesla says it may build elsewhere.
Tesla Megapack Megafactory in Texas advances with major property sale
The plant would handle the full solar cell production chain in one facility, according to the filing, covering wafer and ingot manufacturing, coating, metallization and printing lines, cell testing, automated material handling and cleanroom infrastructure. That scope points to Tesla vertically integrating a part of its supply chain it currently sources largely from overseas partners, mirroring the approach behind its expanding Megapack production in Brookshire, Texas, where Tesla has already built out two buildings for its grid battery business.
The timing lines up closely with Tesla and SpaceX’s other big Texas commitment this month. SpaceX confirmed its Terafab chip factory would land in Grimes County days before this filing surfaced, with construction on that $16.8 billion project starting almost immediately after local officials met with residents. Terafab is meant to produce the AI chips running Tesla’s Optimus robots and Full Self-Driving software, while a solar cell plant would feed a different part of the business, the panels and storage systems Tesla sells to homeowners, businesses and utilities, and increasingly needs to power its own data centers.
Musk has talked about building domestic solar manufacturing capacity before, tying it to the amount of power Tesla’s AI ambitions will require.
