Houston startup unveils sustainable bio-based leather at the rodeo

sustainable materials

Last month’s Houston Livestock Show and Rodeo stirred up another rootin’ tootin’ time for Houstonians and beyond.

But before the annual event galloped into the sunset, there were quite a few memorable innovations on display, with one notably coming from Rheom Materials.

The Houston-based pioneer of next-generation materials presented its scalable, bio-based alternative known as Shorai, a 93 percent bio-based leather, through two custom, western-inspired outfits that showed off cowboy flair through a sustainable lens.

“I'm a Houstonian, I love the rodeo,” Megan Beck, Rheom’s business development manager, recalls. “We're sitting there talking about it one day and we're like, ‘Okay, we've got to do something with this leather to show people how good it can look in apparel, how easy it is to wear.’”

Buoyed by the idea that their materials are meant to “change your impact, not your life,” Rheom captured the real-life energy of their bio-leather outfits under the rodeo’s neon lights in a short commercial video and photo shoot with models donning the samples, while dancing and enjoying the festivities. Rheom created a skirt, a leather jacket, and then a leather top for the look.

“Houston is such a vibrant city,” Beck says. “There's so much innovation here. I think the rodeo is just a really, really great example of that. And so we wanted to take this opportunity to take some of these garments out there and go on the slide, go on some of the rides, go into the wine garden and go dancing, because if you've ever felt some of the materials in the market in this space, they're very stiff, you can't really move in them, they're a little fragile, they kind of fall apart.”

Not only do the models in the video look fashionable, but they also look comfortable, and the leather looks natural and supple. And to the naked eye, Shorai appears to be like the leather most wearers are accustomed to.

“What we really wanted to showcase in this is the energy and the movement of the leather, and to show people how good it can look in apparel, and how easy it is to wear, which I think we were able to accomplish,” Beck says.

Next up, Beck says Rheom wants to scale production of Shorai, the Japanese word for “future,” at a competitive price point, while also reducing its carbon footprint by 80 percent when compared to synthetic leather. According to Beck, Rheom plans to see Shorai products come to market sometime this year.

“We have companies globally right now that are testing materials, that are prototyping, that are making garments, making handbags and footwear, and making eyewear because we have a plastic, as well,” Beck says. “So, this year, I do believe we'll start seeing those products actually come to market, which is very, very exciting for us.”

And with their large-scale production partner already set up for Shorai, Rheom plans to start its first production run of the product soon.

“In April, we'll actually be starting our first production run,” Beck says. “We'll be doing it at full scale, full width, and a full run of materials. So over the next five years, we're only going to just try to increase that capacity.”

Houston biomaterials startup taps partner for commercial-scale production

next-gen news

A Houston-based next-gen material startup has revealed a new strategic partnership.

Rheom Materials, formerly known as Bucha Bio, has announced a strategic partnership with thermoplastic extrusion and lamination company Bixby International, which is part of Rheom Material’s goal for commercial-scale production of its novel biobased material, Shorai.

Shorai is a biobased leather alternative that meets criteria for many companies wanting to incorporate sustainable materials. Shorai performs like traditional leather, but offers scalable production at a competitive price point. Extruded as a continuous sheet and having more than 92 percent biobased content, Shorai achieves an 80 percent reduction in carbon footprint compared to synthetic leather, according to Rheom.

Rheom, which is backed by Houston-based New Climate Ventures, will be allowing Bixby International to take a minority ownership stake in Rheom Materials, as part of the deal.

“Partnering with Bixby International enables us to harness their extensive expertise in the extrusion industry and its entire supply chain, facilitating the successful scale-up of Shorai production,” Carolina Amin Ferril, CTO at Rheom Materials, says in a news release. “Their highly competitive and adaptable capabilities will allow us to offer more solutions and exceed our customers’ expectations.”

In late 2024, Rheom Materials started its first pilot-scale trial at the Bixby International facilities with the goal to produce Shorai for prototype samples.

"The scope of what we were doing — both on what raw materials we were using and what we were creating just kept expanding and growing," founder Zimri Hinshaw previously told InnovationMap.

Podcast: Houston bio-based materials founder rebrands, evolves future-focused sustainability startup

listen in

At first, Zimri T. Hinshaw just wanted to design a sustainable, vegan jacket inspired by bikers he saw in Tokyo. Now, he's running a bio-based materials company with two product lines and is ready to disrupt the fashion and automotive industries.

Hinshaw founded Rheom Materials (née Bucha Bio) in 2020, but a lot has changed since then. He moved the company from New York to Houston, built out a facility in Houston's East End Maker Hub, and rebranded to reflect the company's newest phase and extended product lines, deriving from dozens of different ingredients, including algae, seaweed, corn, other fruits and vegetables, and more.

"As a company, we pivoted our technology from growing kombucha sheets to grinding up bacteria nanocellulose from kombucha into our products and then we moved away from that entirely," Hinshaw says on the Houston Innovators Podcast. "Today, we're designing different materials that are more sustainable, and the inputs are varied."

Now, in addition to Rheom's leather-like alternative, Shorai, the company has a plastic-like material, Benree, that's 100 percent bio based.

"The scope of what we were doing — both on what raw materials we were using and what we were creating just kept expanding and growing," Hinshaw says.

With that major evolution past just kombucha-based textiles, it was time for a new name, ideated by the company's technical team. "Rheom" is the combination of "rheology" — the study of how polymers flow — and "form."

Rheom has also built a state-of-the-art chemicals testing lab at its new facility after moving into it early last year.

"We've got a ton of capabilities now — and we've been growing those since the beginning," Hinshaw says. "Now we have all this testing equipment — things that pull materials apart, things that test the flexibility of materials."

Next up, Rheom, which is backed by Houston-based New Climate Ventures, among other VCs, will raise a series A funding round to continue supporting its growth.

Why 2026 must be the year Texas makes transmission as its top energy priority

guest column

Texas takes pride in running one of the most dynamic and deregulated energy markets in the world, but conversations about electricity rarely focus on what keeps it moving: transmission infrastructure.

As ERCOT projects unprecedented electricity demand growth and grid operators update their forecasts for 2026, it’s becoming increasingly clear that generation, whether renewable or fossil, is only part of the solution. Transmission buildout and sound governing policy now stand as the linchpin for reliability, cost containment, and long-term resilience in a grid under unprecedented stress.

At the heart of this urgency is one simple thing: demand. Over 2024 and 2025, ERCOT has been breaking records at a pace we haven’t seen before. From January through September of 2025 alone, electricity use jumped more than 5% over the year before, the fastest growth of any major U.S. grid. And it’s not slowing down.

The Energy Information Administration expects demand to climb another 14% in 2026, pushing total consumption to roughly 425 terawatt-hours in just the first nine months. That surge isn’t just about more people moving to Texas or running their homes differently; it’s being driven by massive industrial and technology loads that simply weren’t part of the equation ten years ago.

The most dramatic contributor to that rising demand is large-scale infrastructure such as data centers, cloud computing campuses, crypto mining facilities, and electrified industrial sectors. In the latest ERCOT planning update, more than 233 gigawatts of total “large load” interconnection requests were being tracked, an almost 300% jump over just a year earlier, with more than 70% of those requests tied to data centers.

Imagine hundreds of new power plants requesting to connect to the grid, all demanding uninterrupted power 24/7. That’s the scale of the transition Texas is facing, and it’s one of the major reasons transmission planning is no longer back-of-house policy talk but a central grid imperative.

Yet transmission is complicated, costly, and inherently long-lead. It takes three to six years to build new transmission infrastructure, compared with six to twelve months to add a new load or generation project.

This is where Texas will feel the most tension. Current infrastructure can add customers and power plants quickly, but the lines to connect them reliably take time, money, permitting, and political will.

To address these impending needs, ERCOT wrapped up its 2024 Regional Transmission Plan (RTP) at the end of last year, and the message was pretty clear: we’ve got work to do. The plan calls for 274 transmission projects and about 6,000 miles of new, rebuilt, or upgraded lines just to handle the growth coming our way and keep the lights on.

The plan also suggests upgrading to 765-kilovolt transmission lines, a big step beyond the standard 345-kV system. When you start talking about 765-kilovolt transmission lines, that’s a big leap from what Texas normally uses. Those lines are built to move a massive amount of power over long distances, but they’re expensive and complicated, so they’re only considered when planners expect demand to grow far beyond normal levels. Recommending them is a clear signal that incremental upgrades won’t be enough to keep up with where electricity demand is headed.

There’s a reason transmission is suddenly getting so much attention. ERCOT and just about every industry analyst watching Texas are projecting that electricity demand could climb as high as 218 gigawatts by 2031 if even a portion of the massive queue of large-load projects actually comes online. When you focus only on what’s likely to get built, the takeaway is the same: demand is going to stay well above anything we’ve seen before, driven largely by the steady expansion of data centers, cloud computing, and digital infrastructure across the state.

Ultimately, the decisions Texas makes on transmission investment and the policies that determine how those costs are allocated will shape whether 2026 and the years ahead bring greater stability or continued volatility to the grid. Thoughtful planning can support growth while protecting reliability and affordability, but falling short risks making volatility a lasting feature of Texas’s energy landscape.

Transmission Policy: The Other Half of the Equation

Infrastructure investment delivers results only when paired with policies that allow it to operate efficiently and at scale. Recognizing that markets alone won’t solve these challenges, Texas lawmakers and regulators have started creating guardrails.

For example, Senate Bill 6, now part of state law, aims to improve how large energy consumers are managed on the grid, including new rules for data center operations during emergencies and requirements around interconnection. Data centers may even be required to disconnect under extreme conditions to protect overall system reliability, a novel and necessary rule given their scale.

Similarly, House Bill 5066 changed how load forecasting occurs by requiring ERCOT to include utility-reported projections in its planning processes, ensuring transmission planning incorporates real-world expectations. These policy updates matter because grid planning isn’t just a technical checklist. It’s about making sure investment incentives, permitting decisions, and cost-sharing rules are aligned so Texas can grow its economy without putting unnecessary pressure on consumers.

Without thoughtful policy, we risk repeating past grid management mistakes. For example, if transmission projects are delayed or underfunded while new high-demand loads come online, we could see congestion worsen. If that happens, affordable electricity would be located farther from where it’s needed, limiting access to low-cost power for consumers and slowing overall economic growth. That’s especially critical in regions like Houston, where energy costs are already a hot topic for households and businesses alike.

A 2026 View: Strategy Over Shortage

As we look toward 2026, here are the transmission and policy trends that matter most:

  • Pipeline of Projects Must Stay on Track: ERCOT’s RTP is ambitious, and keeping those 274 projects, thousands of circuit miles, and next-generation 765-kV lines moving is crucial for reliability and cost containment.
  • Large Load Forecasting Must Be Nuanced: The explosion in large-load interconnection requests, whether or not every project materializes, signals demand pressure that transmission planners cannot ignore. Building lines ahead of realized demand is not wasteful planning; it’s insurance against cost and reliability breakdowns.
  • Policy Frameworks Must Evolve: Laws like SB 6 and HB 5066 are just the beginning. Texas needs transparent rules for cost allocation, interconnection standards, and emergency protocols that keep consumers protected while supporting innovation and economic growth.
  • Coordination Among Stakeholders Is Critical: Transmission doesn’t stop at one utility’s borders. Regional cooperation among utilities, ERCOT, and local stakeholders is essential to manage congestion and develop systemwide reliability solutions.

Here’s the bottom line: Generation gets the headlines, but transmission makes the grid work. Without a robust transmission buildout and thoughtful governance, even the most advanced generation mix that includes wind, solar, gas, and storage will struggle to deliver the reliability Texans expect at a price they can afford.

In 2026, Texas is not merely testing its grid’s capacity to produce power; it’s testing its ability to move that power where it’s needed most. How we rise to meet that challenge will define the next decade of energy in the Lone Star State.

New Gulf Coast recycling plant partners with first-of-kind circularity hub

now open

TALKE USA Inc., the Houston-area arm of German logistics company TALKE, officially opened its Recycling Support Center earlier this month.

Located next to the company's Houston-area headquarters, the plant will process post-consumer plastic materials, which will eventually be converted into recycling feedstock. Chambers County partially funded the plant.

“Our new recycling support center expands our overall commitment to sustainable growth, and now, the community’s plastics will be received here before they head out for recycling. This is a win for the residents of Chambers County," Richard Heath, CEO and president of TALKE USA, said in a news release.

“The opening of our recycling support facility offers a real alternative to past obstacles regarding the large amount of plastic products our local community disposes of. For our entire team, our customers, and the Mont Belvieu community, today marks a new beginning for effective, safe, and sustainable plastics recycling.”

The new plant will receive the post-consumer plastic and form it into bales. The materials will then be processed at Cyclyx's new Houston Circularity Center, a first-of-its-kind plastic waste sorting and processing facility being developed through a joint venture between Cyclix, ExxonMobil and LyondellBasell.

“Materials collected at this facility aren’t just easy-to-recycle items like water bottles and milk jugs. All plastics are accepted, including multi-layered films—like chip bags and juice pouches. This means more of the everyday plastics used in the Chambers County community can be captured and kept out of landfills,” Leslie Hushka, chief impact officer at Cyclyx, added in a LinkedIn post.

Cyclyx's circularity center is currently under construction and is expected to produce 300 million pounds of custom-formulated feedstock annually.

Houston quantum simulator research reveals clues for solar energy conversion

energy flow

Rice University scientists have used a programmable quantum simulator to mimic how energy moves through a vibrating molecule.

The research, which was published in Nature Communications last month, lets the researchers watch and control the flow of energy in real time and sheds light on processes like photosynthesis and solar energy conversion, according to a news release from the university.

The team, led by Rice assistant professor of physics and astronomy Guido Pagano, modeled a two-site molecule with one part supplying energy (the donor) and the other receiving it (the acceptor).

Unlike in previous experiments, the Rice researchers were able to smoothly tune the system to model multiple types of vibrations and manipulate the energy states in a controlled setting. This allowed the team to explore different types of energy transfer within the same platform.

“By adjusting the interactions between the donor and acceptor, coupling to two types of vibrations and the character of those vibrations, we could see how each factor influenced the flow of energy,” Pagano said in the release.

The research showed that more vibrations sped up energy transfer and opened new paths for energy to move, sometimes making transfer more efficient even with energy loss. Additionally, when vibrations differed, efficient transfer happened over a wider range of donor–acceptor energy differences.

“The results show that vibrations and their environment are not simply background noise but can actively steer energy flow in unexpected ways,” Pagano added.

The team believes the findings could help with the design of organic solar cells, molecular wires and other devices that depend on efficient energy or charge transfer. They could also have an environmental impact by improving energy harvesting to reduce energy losses in electronics.

“These are the kinds of phenomena that physical chemists have theorized exist but could not easily isolate experimentally, especially in a programmable manner, until now,” Visal So, a Rice doctoral student and first author of the study, added in the release.

The study was supported by The Welch Foundation,the Office of Naval Research, the National Science Foundation CAREER Award, the Army Research Office and the Department of Energy.
