Last month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.

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.

Houston-area company to develop next-gen batteries for electric helicopters

emissions-free flight

Webster-based KULR Technology Group has announced a strategic co-development collaboration with Robinson Helicopter Company (RHC) to develop a next-generation, high-performance battery system for the eR66 battery-electric helicopter demonstrator.

KULR, an electronics manufacturing company, will serve as the developer of the advanced battery system for the eR66 platform. KULR will design and integrate a high-performance battery structure that uses its proprietary battery safety technologies and thermal management solutions, previously developed for aerospace and spaceflight applications.

California-based Robinson Helicopter Company is the world's leading manufacturer of civil helicopters. Its eR66 is expected to deliver zero-emission, affordable and quiet performance for “high-demand applications.”

“Robinson Helicopter has built more civil helicopters than any manufacturer on Earth, and their commitment to reliability is exactly the standard KULR’s battery architecture is designed to meet,” Michael Mo, CEO of KULR, said in a news release. “KULR’s battery systems have been qualified for NASA spaceflight. They were designed from day one for dual use: a primary flight cycle and a certified second life. The eR66 is where that architecture proves itself in rotorcraft.”

David Smith, president and CEO of Robinson Helicopter Company, cited the partnership as a shift in service for commercial and civil operations and touted the potential environmental benefits.

“By integrating electric propulsion, we aren't just reducing our environmental impact; we are unlocking critical new capabilities for life-saving missions,” Smith added in the release. “For use cases like rapid organ and tissue transport, the reduced acoustic signature and zero-emission profile ensure that time-sensitive, low-emission deliveries are faster, quieter, and more sustainable than ever before."

The companies say, through the partnership, they aim to:

  • Advance eR66 performance
  • Enhance aviation safety
  • Increase cost efficiency
  • Uphold American aerospace leadership
  • Support decarbonization
  • Promote circular economy principles

Tesla's EV Robotaxis officially launch in Texas' largest metros

On The Road

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Major Texas energy port wrestles with water crisis due to years of drought

Resource Report

In parched southern Texas, a yearslong drought has depleted Corpus Christi's water reserves so gravely that the city is scrambling to prevent a shortage that could force painful cutbacks for residents and hobble the refineries and petrochemical plants in a major energy port.

Experts said the city didn't expect such a bad drought, and new sources of reliable water didn't arrive as expected. Those problems arose as the city increased its water sales to big industrial customers.

“We just have not kept up with water supply and water infrastructure like we should have. And it's decades in the making,” said Peter Zanoni, the city manager since 2019.

Corpus Christi, a city of about 317,000 people that also supplies water to nearby counties, is closely tied to its oil and gas industry. The region makes everyday essentials like fuel and steel and ships them to the world.

Zanoni said it is highly unlikely the city will run out of water, but without significant rainfall or new sources, residents may face forced cutbacks and industry may have to do with less. At a time when the Iran war is already raising gas prices, the shortage is hitting an area that produces 5% of the U.S. gasoline supply.

Droughts are common, but this one has dragged on for most of the past seven years. Key reservoirs are at their lowest point ever. The quickest fix is different weather.

“We are actively praying for a hurricane,” former city council member David Loeb said, half in jest. Loeb doesn't want anyone injured, but after wrestling with previous droughts in his time on the council, he feels the lack of rain acutely.

The drought isn't expected to lift by summer, leaving officials scrambling to tap more groundwater to avoid an emergency.

Lessons from last time

After the last drought in the early 2010s, the city approved a pipeline extension to bring in more water from the Colorado River and promoted conservation. In the years that followed, water use actually fell. The city, seeing opportunity, added a petrochemical plant and steel mill to its long list of industrial customers.

City officials had allowed for drought in their calculations — just not this kind of drought, Zanoni said. It has hit especially hard because reservoirs never fully recharged after the last one.

And it's come at a bad time.

After many years, the pipeline extension finally delivered its full capacity only last year. Meanwhile, discussion of building a desalination plant that would remove salt from seawater — a potentially drought-proof solution recommended in 2016 — bogged down over concerns about costs as high as $1.3 billion and environmental impact.

“If the then-city council had followed through on that, we would have had that plant up and running by now,” Zanoni said.

It's an industry town

Corpus Christi has followed its long-established plan for reducing water use. Stage 1 seeks voluntary actions from citizens like taking shorter showers and limiting how often they can water. Currently, the city is in Stage 3, which means pauses on many outdoor water uses.

Many residents are angry that they can’t water their lawns, that their bills are set to rise sharply and that they may face fines, said Isabel Araiza, co-founder of a grassroots group active on water issues. Some don’t feel industry will be asked to share in the pain, she said.

The city's drought plan allows for charging residents and businesses extra if they use lots of water. But big industry, which Zanoni says consumes as much as 60% of the city's water, can opt to pay a permanent surcharge to avoid the possibility of having a much larger fee added in times of drought.

Araiza calls it a bad system. Once industry pays the surcharge, she said, they have no incentive to conserve water.

The city has defended the system, saying in a statement that industry does not “get a pass on water conservation” or forced curtailment. The statement said the business surcharges have raised $6 million a year.

It is wrong to suggest industry isn’t helping, said Bob Paulison, executive director of the Coastal Bend Industry Association. Companies have stopped landscaping, they recycle water for essential cooling needs and they are looking for alternative water sources, he said.

The city hasn't imposed extra costs on anyone yet.

But Zanoni said water rates may eventually double as the city invests roughly $1 billion on infrastructure — costs that some argue will disproportionately benefit industry and make life for residents more expensive.

What's the way out?

The city is in a water emergency when it has 180 days before water supply can't keep up with demand. Officials have run through different scenarios for getting new water and the drought easing, and have said an emergency could come as early as May, as late as October, or not at all.

The city has tapped into millions of gallons of new groundwater, and it hopes to get even more.

The biggest unknown is the Evangeline Groundwater Project, which involves a pipeline and about two dozen wells that could add enough water to head off an emergency. It still needs state approval but the city hopes water could be flowing as soon as November. New sources come with drawbacks – some have raised water quality concerns, and there are worries too much pumping could deplete groundwater.

If the city has to declare a water emergency, it would be able to more aggressively curtail water use – mandatory reductions that would apply evenly to all industry and residents. That is a sensitive decision and is likely to be a “knock-down drag-out bloodbath,” Loeb said.

Because residents on average have already reduced their water use, future mandatory cuts are likely to fall heavier on industry.

“It’ll be an unbelievable disaster,” said Don Roach, former assistant general manager of the San Patricio Municipal Water District that has lots of industrial customers in the area. “When you cut the cooling water off to most of these industries, they just have to shut down. There’s no other way around it.”

Paulison said companies that produce fuel, polymers, iron and steel “have the least amount of flexibility in just cutting water usage.” He added, however, that companies remain optimistic they can reduce usage, adapt and continue operations.

Zanoni said the city's plans should buy time to avert the worst.

“We are hoping we don’t get there, but we don’t work on hope,” he said.
