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.'"

Houston's new state-of-the-art academy FLAMA breaks ground at historic site

Groundbreaking Education

Houston’s newest school for arts and music broke ground in October in the city’s historic East End. The Frank Liu Jr. Academy for Music and Arts (FLAMA), a tuition-free charter school, will welcome students in pre-K through 8th grade next August.

Members of the Liu family, the school’s founding board members, elected officials, and East End community partners gathered at Buffalo Bayou Partnership’s historic Turkey Bend development for the official groundbreaking ceremony on October 8, which kicked off with a performance by the Kinder High School for the Performing and Visual Arts’ Mariachi group.

The new school is on a portion of the former Folgers Coffee Plant, located at 235 N. Norwood St. OMA, an international architectural firm known for its approach to urbanism, cultural projects, and adaptive reuse, is transforming the 1930s plant into a state-of-the-art educational facility.

“We’re excited to celebrate this milestone for FLAMA and look forward to seeing the transformation of the historic Folgers plant into a new home for music and arts education,” said Jason Long, one of the firm’s partners. “Like fine-tuning an instrument, our design recalibrates the existing industrial structure into an open, connected, and expressive environment for learning. FLAMA will be a new learning environment that builds on the character of the existing building while giving it new life for the community.”

Unfolding across three stories, the school draws inspiration from Montessori education principles, which prioritize openness, independence, and collective learning through shared “neighborhoods.”

It all begins when students, families and guests enter through a private courtyard. The welcoming space will change the building’s original industrial facade into a brightly colored, kid-friendly spot, complete with yellow and green blocks spelling out the school’s name. The original windows will be restored to preserve the building’s historic character and upgraded to meet contemporary energy standards. Similarly, all of the school’s classrooms are located around the building’s perimeter, providing an abundance of natural light.

Inside, FLAMA’s three stories are divided so that younger students will find their classrooms at the school’s base, and they will move upward through the school as they progress through grade levels. The ground level has a common area for younger kids that could host drum circles, movement classes, or “breakout play.”

Children in first and second grade have their own larger open space, with an eye-catching staircase, that's inspired by the curve of a French horn. The space lends itself to everything from small gatherings to performances by the school’s early musicians.

As students progress through third grade and up, they’ll find FLAMA’s upper floors created to meet their growing artistic and intellectual needs. One example is the open library, a shared spot for students in third through fifth grades. It has flexible furniture that can transform the space into a place for group study and project work, as well as one that can host after-school activities. Directly above this library is a second common room for middle schoolers where students in sixth, seventh, and eighth grades can study.

These two libraries are connected by an F-shaped floor opening that references both the F-hole of a string instrument and the forte symbol. Musicians know this curly f as a note indicating them to play a passage with strength. That could easily be a metaphor for the school itself, which will combine high-quality education with rigorous academics. This visual cue emphasizes FLAMA’s desire for music and art instruction to amplify learning across reading, writing, math, and science.

“This will be a place where children can discover their talents, families can find opportunities close to home, and music and art can open the doors to a stronger education,” said Congresswoman Sylvia Garcia, who attended the groundbreaking. “I know how much it matters when someone brings opportunity within the reach of a child.”

Dr. R. Scott Allen, FLAMA’s founding superintendent and former principal of Kinder HSPVA, spoke about the school’s vision to pair a rigorous, engaging academic opportunity with deep immersion in music and visual arts.

Congressman Christian Menefee, State Senator Carol Alvarado, and Houston City Councilmember Mario Castillo also delivered remarks at the ceremony, speaking about the school’s power to not only transform Houston’s Second, Third, and Fifth Ward communities, but also bring incredible education opportunities to students. Former Mayor Annise Parker, former State Board of Education Member Staci Childs, State Representative Christina Morales, and Houston City Councilmembers Joaquin Martinez and Sallie Alcorn also attended the event.

“In this city, known for our undeniable contributions to music and arts, the gap has never been ability or talent; it has always been opportunity, and opportunity can be built,” said Kirby Liu, who spoke at the groundbreaking, memorializing his late brother’s vision of arts education for the youngest Houstonians. “When it comes to opportunity being foreclosed on our children, we will try like hell to bust those damned doors down.”

The Frank Liu Jr. Foundation has pledged $20 million in financial support during FLAMA’s first years of operation. Applications are now open for kindergarten and first grade for the 2027-2028 school year.

New manufacturing facility breaks ground at NASA’s Johnson Space Center

making space

HITT Contracting has broken ground on NASA’s Applied Spaceflight Fabrication Facility (ASFF) at Johnson Space Center, the Washington, D.C.-based construction firm announced late last month.

The project, known as Building 70, will house a high-bay machine shop to support component production for future NASA space missions, according to HITT. The 37,625-square-foot building is the first part of a larger goal to create an engineering complex that unites assembly space, lab capabilities and manufacturing at JSC. It will consolidate machining equipment and operations that are currently spread across multiple campus buildings into one location.

The project broke ground in October at JSC’s Historic District. The Houston Business Journal reports construction is expected to wrap in August of 2028.

“This project will modernize facilities that support America’s space missions,” PJ Ross, chief financial officer at HITT, said in a LinkedIn post. “Proud of our team and partners as we begin construction that will advance aerospace testing and innovation.”

HITT Contracting is one of seven companies awarded infrastructure contracts by NASA earlier this year for work at JSC. According to NASA, the construction contracts “[support] up to $300 million in upgrades to mission‑support facilities, utilities, and equipment across the NASA Johnson campus.”

Construction Drive reports that HITT will also renovate Building 13 South on the JSC campus as part of the $300 million initiative.

“Building for precision manufacturing starts with understanding how the space needs to perform,” Todd Hudson, vice president at HITT Contracting, added in the release. “Our team brings the technical expertise and collaborative approach to deliver a facility that meets the Johnson Space Center’s needs today and supports the next generation of spaceflight innovation. We’re proud to continue our partnership with NASA.”

NASA also recently announced awards as part of its expanded Moon Base exploration, science and infrastructure capabilities. Houston-based Intuitive Machines and seven other spacetech companies, including SpaceX, Blue Origin and Firefly Aerospace, were selected to receive funding.

The awards are part of the next phase of NASA’s CLPS (Commercial Lunar Payload Services) initiative, which will grant the companies a combined total of up to $10 billion over 10 years.

Intuitive Machines and Webster-based MEI Technologies were also awarded contracts this past summer from NASA to develop robots for exploring the surface of Mars. Read more here.
