Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic.

The research was led by Muhammad Maksud Rahman, an assistant professor of mechanical and aerospace engineering at the University of Houston and an adjunct assistant professor of materials science and nanoengineering at Rice University. The team shared its findings in a study in the journal Nature Communications earlier this month. M.A.S.R. Saadi, a doctoral student in material science and nanoengineering at Rice, served as the first author.

The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties,” according to the researchers.

Biomaterials typically have weaker mechanical properties than their synthetic counterparts. However, the team was able to develop sheets of material with similar strengths to some metals and glasses. And still, the material was foldable and fully biodegradable.

To achieve this, the team developed a rotational bioreactor and utilized fluid motion to guide the bacteria fibers into a consistent alignment, rather than allowing them to align randomly, as they would in nature.

The process also allowed the team to easily integrate nanoscale additives—like graphene, carbon nanotubes and boron nitride—making the sheets stronger and improving the thermal properties.

“This dynamic biosynthesis approach enables the creation of stronger materials with greater functionality,” Saadi said in a release. “The method allows for the easy integration of various nanoscale additives directly into the bacterial cellulose, making it possible to customize material properties for specific applications.”

Ultimately, the scientists at UH and Rice hope this discovery could be used for the “next disposable water bottle,” which would be made by biodegradable biopolymers in bacterial cellulose, an abundant resource on Earth.

Additionally, the team sees applications for the materials in the packaging, breathable textiles, electronics, food and energy sectors.

“We envision these strong, multifunctional and eco-friendly bacterial cellulose sheets becoming ubiquitous, replacing plastics in various industries and helping mitigate environmental damage,” Rahman said the release.

Innovative Houston plastics company scores $100M 'Green Loan' and prepares to scale

seeing green

Fueled by a new $100 million credit facility, a Houston-based company that specializes in plastics recycling is establishing a nationwide network of recycling plants.

Circulus Holdings secured the $100 million credit facility from Riverstone Credit Partners, which has an office in Houston. This "green" loan is aimed at supporting environmental sustainability.

David Hudson, founder and CEO of Circulus, says in a news release that the credit facility "enables Circulus to rapidly develop a broad network of facilities and further the company's commitment to sustainable manufacturing. We look forward to supporting green-based jobs and preserving our environment for future generations."

Circulus, a portfolio company of Houston-based private equity firm Ara Partners, recently opened its first plastics recycling facility. The 110,000-square-foot plant is in Riverbank, California, near Modesto. It employs 45 people. So far, other Circulus plants, each of which will be larger than the California facility, are planned for Alabama, Oklahoma, the Midwest, and the Northeast.

Circulus is building plants that will transform lower-grade plastic into post-consumer resin so that it's suitable for commercial and industrial uses.

Circulus says it is diverting plastic from landfills, incinerators, and oceans and "upcycling" it into products, including plastic bags and plastic wrap. Customers for those products include retailers, resin producers, packaging manufacturers, and makers of consumer packaged goods. The company says greenhouse gas emissions associated with production of its post-consumer resin are about 88 percent below that of virgin resin.

"Through our significant investment in infrastructure and commitment to manufacturing excellence, we are supporting green job creation and reinforcing the nation's global position in sustainable manufacturing," Hudson says in a news release.

Before Circulus, Hudson was an operating partner at Ara Partners.

Founded in 2019, Circulus employs a dozen people in Houston and plans to add workers here as its network of facilities expands. Circulus is set up as a public benefit LLC, a for-profit business that promotes a social benefit for the public.

Ara Partners invests in decarbonization-focused businesses in the manufacturing, chemicals and materials, energy, and food and agriculture sectors. Aside from Circulus, portfolio companies include Houston-based Path Environmental Technology, which provides a decarbonization-oriented industrial services platform for above-ground storage tanks, and Arlington-based Priority Power Management, an energy services provider whose priorities include carbon neutrality and smart energy.

Circulus is breaking into a plastics recycling market whose global size in 2020 was estimated at $39.9 billion, according to Imarc Group, a market research company. The firm projects the market will grow to $56.5 billion by 2026.

"The demand for plastic material has been constantly increasing across several industries like food and beverage, automotive, packaging, and healthcare. The development of these industries can be accredited to rising population, inflating disposable incomes, and continuous product innovations," Imarc Group says. "In this context, higher manufacturing cost of virgin resins has necessitated the use of recycled plastic products, thereby bolstering the growth of the global recycled plastics market."

Verified Market Research estimates the global market for post-consumer recycled plastics at nearly $15.2 billion in 2020 and forecasts it will rise to almost $22.4 billion by 2028.

"The products produced from these plastics close the loop by diverting them from landfills and enabling them to be recycled," Verified Market Research says. "The advantages of employing post-consumer plastics also assist in addressing … microplastics in the environment. Microplastics are originated from plastic waste that has been deposited into the environment."

Houston startup raises $30M, plans to be 'next iconic chemical company' with plant-based alternatives

climate tech

While Forbes recently anointed Houston-based Solugen Inc. as one of the next billion-dollar "unicorns" in the startup world, Dr. Gaurab Chakrabarti shrugs off the unicorn buzz.

Chakrabarti, a physician and scientist who's co-founder and CEO of the startup, concedes he doesn't know whether Solugen will be worth $1 billion or not. But he does know that the startup aspires to be a key competitor in the emerging "climate tech" sector, whose players strive to combat climate change. Chakrabarti estimates the climate-tech chemical space alone represents a global market opportunity valued at $1 trillion to $2 trillion per year.

Solugen's overarching goal in the climate-tech market: Replace petroleum-based chemicals with plant-based substitutes.

"I'd love it if we were the poster child that drives climate tech to be the next big, sexy trend," Chakrabarti says.

Chakrabarti acknowledges Solugen's investors, executives, and employees hope the startup succeeds financially. But success, he believes, goes beyond making money and plotting an exit strategy. Instead, Chakrabarti emphasizes "a shift in thinking" on climate tech that he says promises to transform the fledgling sector into a "true niche" that'll be "good for everyone."

"Who cares if people are all hyped up for the wrong reasons?" says Chakrabarti, referring to the unicorn speculation.

Solugen sits at the crossroads of biology and chemistry. In short, the startup taps into plant-centered biotechnology to produce environmentally friendly chemicals and "decarbonize" the chemical industry.

"Quite simply, we want to become the next DowDuPont or the next iconic chemical company, but using principles of green chemistry instead of principles from petroleum chemistry," Chakrabarti says.

If Solugen does reach the icon stratosphere, Chakrabarti envisions it doing so on a speedy schedule. In the traditional petrochemical market, it can take 10 to 20 years to put a new product on the market, he says. "I don't have that kind of time. I'm a very impatient person," Chakrabarti says.

Spurred by that restlessness, Chakrabarti seeks to propel Solugen's products from concept to commercialization in the span of two years. He says the startup already has proven the ability to do that with its sugar-derived hydrogen peroxide product.

"We're going to continue to do that, and it would be great if we can continue demonstrating new [products] coming to market once a year," says Chakrabarti, who grew up in Sugar Land.

Solugen seems to have plenty of financial fuel to make that happen. In April, Solugen raised $30 million in venture capital as an add-on to its Series B funding, which initially closed May 2019. That brings its total VC haul to $68 million since it was founded in 2016, according to Forbes. The recent funding lifted the company's valuation to $250 million, putting it $750 million away from unicorn territory.

Chakrabarti doesn't dismiss the notion of an eventual IPO for Solugen but says being acquired isn't "terribly interesting to me."

"If you want to make money, you can always go be a banker," he notes.

Chakrabarti estimates Solugen will generate $30 million to $40 million in revenue this year, up from $12 million in 2019. Profit remains elusive, though, as the company pours its gains into R&D. The company graduated in 2017 from the Y Combinator startup accelerator. Aside from Y Combinator and Unicorn Venture Partners, investors include Founders Fund, Refactor Capital, Fifty Years, and KdT Ventures.

Solugen's current lineup features fewer than a half-dozen products, which are sold to industrial and government customers. Hundreds more products are in the pipeline for use in sectors like agriculture and energy, Chakrabarti says.

"It's one of the blessings and curses of this company — there's always something to work on, always something big to scale up," says Chakrabarti, who earned his M.D. and Ph.D. from the University of Texas Southwestern Medical Center in Dallas.

Working on selling Solugen's current products and developing its new products are 70 employees, located at its headquarters in Houston and its new production facility in Lubbock. By the end of this year, the startup should employ close to 100 people, Chakrabarti says.

Chakrabarti hesitates to identify Solugen's competitors, as he believes a perceived rival very well could end up becoming a partner.

"I think everyone eventually should be a partner of Solugen, not competition," he says. "It's an ideology that's actually the competition, an ideology like, 'We've always used petrochemistry. This is just how it's been done.'"

Tech giant Apple opens Advanced Manufacturing Center at massive Houston facility

up and running

Cupertino, California-based Apple Inc. unveiled its Advanced Manufacturing Center in the Houston area last week, marking the completion of the second of three facilities the tech giant plans to launch in the city by the end of this year.

The 20,000-square-foot training center will welcome small- and medium-sized businesses for free training and educational sessions to "help accelerate smart manufacturing across America," according to a release from Apple. Apple opened a similar Apple Manufacturing Academy in Detroit last year.

The AMC is part of Apple's 500,000-square-foot site in northwest Harris County. It also features a massive manufacturing site for Apple’s advanced AI servers and Mac mini. The facility was originally slated to open in 2026, but Apple began producing its advanced AI servers ahead of schedule in 2025.

The company said it plans to begin manufacturing its Mac mini at the site this year. The move will bring production of the compact desktop computer to the U.S. for the first time.

“In less than nine months, we have invested hundreds of millions of dollars into this Houston facility. We stood up a factory, started production, and shipped the first advanced AI servers off the line. Today, we’re thrilled to open our new Advanced Manufacturing Center, a place where businesses, workers, and students can learn the same innovative processes that we use to make Apple’s most groundbreaking products. And we’re pleased to begin Mac mini production later this year,” Tim Cook, Apple’s CEO, said in the news release. “We believe in American workers and American ingenuity, and we are moving at an incredible pace because we want to build more than great products. We want to build the future of American manufacturing.”

Apple's Houston expansion is part of a $600 billion commitment the company made to the U.S. in 2025.

The company originally announced plans in February 2025 to open a 250,000-square-foot Houston factory, but doubled the facility's planned size about a year later. Apple has reported that the factory will employ thousands of workers.

“Houston is grateful to Apple for this significant investment in our city. The Advanced Manufacturing Center will create local jobs and will continue improving the quality of life of Houston residents," Houston Mayor John Whitmire added in the release. "The AMC also recognizes our city as a growing technology hub and solidifies Houston’s leadership in the manufacturing sector of the United States.”

The opening comes on the heels of New Jersey-based pharmaceutical giant Bristol Myers Squibb Co. officially naming Houston home of its new $2.3 billion, state-of-the-art manufacturing site. Read more here.

$5B MD Anderson-anchored Austin medical center to break ground this fall

moving forward

Construction on the $1 billion first phase of the AI-native University of Texas Dell Medical Center in Austin—which will feature a hospital operated by Houston’s UT MD Anderson Cancer Center—is set to start this fall.

The UT System Board of Regents approved funding for first-phase construction on Aug. 12.

The medical center—now expected to cost $5 billion, up from the initial $2.9 billion estimate—will span about 2.5 million square feet. It will include 300 to 500 patient beds, outpatient facilities, an emergency department and specialized care for cancer patients.

MD Anderson will bring its world-renowned oncology programs to the center’s integrated health care model, Dr. Claudia Lucchinetti, senior vice president of medical affairs at UT Austin and dean of the university’s Dell Medical School, tells Health Leaders.

Earlier this year, Austin tech billionaire Michael Dell and his wife, Susan, pledged $750 million for development of the medical center. The medical center, scheduled for completion in December 2030, will be a cornerstone of the new 300-acre UT Dell Campus for Advanced Research, a medical education and research hub.

“Through this new campus and medical center, Texas will lead America in health care innovation,” Gov. Greg Abbott said when the research campus was announced in April. “The next generation of medical breakthroughs will take place in Central Texas.”

The medical center will fold AI tools and other technology into the infrastructure, rather than having them added after it’s built. Among other capabilities, the technology will monitor real-time medical data, automate data entry, and help health care professionals quickly predict and identify risks to patients, according to Health Leaders.

“We are not just building a new medical center,” Lucchinetti says. “We are building a fundamentally new model of health. It’s not just a new facility. It’s not just a new collaboration. It is a convergence of capabilities that rarely come together at the same time.”
