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."

Rice University partners with astronaut foundation to offer new STEM scholarship

space scholars

Rice University has partnered with The Astronaut Scholarship Foundation (ASF) to offer a new scholarship opportunity for junior or senior STEM majors, beginning this spring.

The prestigious Astronaut Scholarship includes up to $15,000, mentorship, networking and a paid trip to the ASF Innovators Symposium and Gala. The scholarship is funded by the James A. Lovell Jr. Family Endowment, in honor of the late American astronaut and founder of the ASF.

“This scholarship opportunity represents an exciting new avenue for Rice STEM students to synthesize their experiences in courses and research and their commitment to advancing the public good as leaders in their field,” Danika Brown, executive director for the Center for Civic Leadership at Rice, said in a news release. “We are so grateful to the Lovell family and to the foundation for investing in Rice students, and we are confident that the foundation will be impressed with our nominees and that selected students will have a life-changing experience as astronaut scholars.”

The Rice Space Institute and the Center for Civic Learning recently hosted the ASF at the Ralph S. O’Connor Building for Engineering and Science.

At the ASF event, Jeff Lovell—son of James Lovell, who commanded Apollo 13 and flew on Apollo 8—announced the scholarship aimed at Rice STEM students. Charlie Duke, who served as spacecraft communicator for the Apollo 11 Moon landing and as the lunar module pilot for Apollo 16, also spoke at the event.

The ASF awarded 74 scholarships to students from 51 universities across the U.S. last May.

The ASF awarded its first seven $1,000 scholarships in 1986 to pay tribute to the Mercury 7 astronauts. It has since awarded more than $10 million to more than 850 college students.

So far, only students from Texas A&M University and the University of Texas at Austin have received the scholarship in Texas.

Houston hospital first in U.S. to use new system for minimally invasive surgery

sharper images

Houston’s Baylor St. Luke’s Medical Center has introduced an innovative new surgical imaging system that will allow surgeons to increase the number of minimally invasive procedures as well as reposition on the fly during operations.

Minimally invasive surgery has been shown across the board to improve patient outcomes with less chance of infection and shorter recovery times compared to traditional open surgery. However, the human body is not exactly easy to work on through small incisions, necessitating the development of state-of-the-art cameras and imaging technology to guide surgeons.

Enter GE HealthCare’s Allia Moveo, now a part of the Baylor St. Luke’s Medical Center operating room. Using cutting-edge technology, it uses the same high-definition imaging usually seen in the catheterization lab at speeds fast enough to respond to shifting surgical conditions. Its cable-free setup allows surgeons to switch positions much faster, and it features advanced 3D imaging that compensates for breathing motion and interference from metal implants.

Its design supports a range of cardiovascular, vascular, non-vascular, interventional and surgical procedures, according to CommonSpirit Health, a nonprofit Catholic health network, of which Baylor St. Luke's is a member.

“This innovative platform enhances how our clinicians navigate complex minimally invasive procedures by improving mobility, image clarity, and workflow efficiency. It strengthens our ability to deliver precise, patient-centered care while supporting our teams with technology designed for the evolving demands of modern interventional medicine,” Dr. Brad Lembcke, president of Baylor St. Luke’s Medical Center, said in a news release from Baylor and the Texas Heart Institute.

Baylor St. Luke’s is the first hospital in the U.S. to use the Allia Moveo technology. The definition and responsiveness of the new system allow surgeons to navigate the body with greater accuracy and smaller incisions, even for very delicate operations.

“Allia Moveo gives us the flexibility and image quality needed to manage increasingly complex minimally invasive procedures with greater confidence,” Dr. Gustavo Oderich, vascular surgeon and professor of surgery at Baylor College of Medicine, added in the release. “The ability to quickly reposition the system, obtain high-quality 3D imaging, and integrate advanced guidance tools directly into the workflow enhances procedural accuracy. This technology supports our mission to push the boundaries of what is possible in endovascular and interventional surgery.”

Houston clocks in as one of the hardest working cities in America

Ranking It

Houston and its residents are proving their tenacity as some of the hardest working Americans in 2026, so says a new study.

WalletHub's annual "Hardest-Working Cities in America (2026)" report ranked Houston the 37th most hardworking city nationwide. H-town last appeared as the 28th most industrious American city in 2025, but it still remains among the top 50.

The personal finance website evaluated 116 U.S. cities based on 11 key indicators across "direct" and "indirect" work factors, such as an individual's average workweek hours, average commute times, employment rates, and more.

The U.S. cities that comprised the top five include Cheyenne, Wyoming (No. 1); Anchorage, Alaska (No. 2); Washington, D.C. (No. 2); Sioux Falls, South Dakota (No. 4); and Irving, Texas (No. 5). Dallas and Austin also earned a spot among the top 10, landing as No. 7 and No. 10, respectively.

Based on the report's findings, Houston has the No. 31-best "direct work factors" ranking in the nation, which analyzed residents' average workweek hours, employment rates, the share of households where no adults work, the share of workers leaving vacation time unused, the share of "engaged" workers, and the rate of "idle youth" (residents aged 16-24 that are not in school nor have a job).

However, Houston lagged behind in the "indirect work factors" ranking, landing at No. 77 out of all 116 cities in the report. "Indirect" work factors that were considered include residents' average commute times, the share of workers with multiple jobs, the share of residents who participate in local groups or organizations, annual volunteer hours, and residents' average leisure time spent per day.

Based on data from The Organisation for Economic Co-operation and Development (OECD), WalletHub said the average American employee works hundreds of more hours than workers residing in "several other industrialized nations."

"The typical American puts in 1,796 hours per year – 179 more than in Japan, 284 more than in the U.K., and 465 more than in Germany," the report's author wrote. "In recent years, the rise of remote work has, in some cases, extended work hours even further."

WalletHub also tracked the nation's lowest and highest employment rates based on the largest city in each state from 2009 to 2024.
