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."

World Cup's 14-mile Green Corridor to leave lasting impact on Houston

Big Win

The FIFA World Cup 2026 Houston Host Committee has announced new details about its massive Green Corridor project, including the many improvements that will outlast the iconic sporting event taking place in Houston this summer.

The Green Corridor will be a 14-mile long verdant artery connecting multiple major landmarks in Houston through safe, walkable paths that include shade trees and other improvements. First conceived in 2024 by the Sustainability Subcommittee led by Elizabeth Carlson, it will unite East Downtown, Downtown, Midtown, the Museum District, and Third Ward through a hike and bike trail as well as METRO Rail stops. Though the Green Corridor is beginning its life as a showcase for the city to visitors attending the FIFA World Cup June 14 -July 4, it will remain a permanent installation for Houstonians to travel the city without cars.

Management of the project is being handled by Impact Houston 26, a portion of the Host Committee empowered by the Harris County-Houston Sports Authority’s Sports Authority Foundation to promote long-term benefits to the city after the World Cup. Funding partners include private corporations as well as civic organizations such as the City of Sugar Land and Rice University.

“The Green Corridor reflects what Impact Houston 26 is all about, using the FIFA World Cup as a catalyst to deliver lasting environmental benefits for our city,” Carlson said in a statement. “Through Impact Houston’s pillar on sustainability, we’re able to collaborate with local stakeholders to create not just demonstrations of resilience and innovation but education and engagement in the community, a meaningful legacy long after 2026.”

The corridor will provide access to both Houston Stadium (also known as NRG Stadium) and the FIFA Fan Festival, as well as improve existing paths like the Columbia Tap Trail in Third Ward. These improvements include the installation of shade structures, native plantings, expanding the tree canopy, air quality monitoring devices, and water and bike repair stations.

Impact Houston 26 is also working with local institutions like the Houston Zoo, Greentown Labs, and Discovery Green to install various educational materials along the Green Corridor.

Below is a breakdown of other improvements planned or completed as part of the Green Corridor.

  • Downtown Houston Main Street Promenade: Four permanent shade structures, native plants, and expanding the tree canopy by 154% to be implemented by May 2026. Further shade structures and plantings planned for Texas Avenue.
  • East Downtown Management District: Native tree plantings and landscaping in and around the FIFA Fan Festival site to improve first/last mile connectivity around the Green Corridor.
  • Columbia Tap Trail: Installation of 325 solar lights.
  • Stadium Park/Astrodome and TMC/Dryden plus Fannin South Transit Center: Various landscaping and safety enhancements.
  • Midtown Houston: $1.5 million in landscaping and beautification along the Red Line, including over 80 trees, native plantings, water stations, waste receptacles, crosswalk improvements, and public art installations.

The Green Corridor is only one of the World Cup Host Committee's sustainability initiatives. In January, it announced the "New Year, New Hou" program that provides hospitality businesses such as restaurants and hotels with one of three certifications.

Houston humanoid robotics startup Persona AI hires new strategy leader

new hire

Houston-based Persona AI, a two-year-old startup that develops robots for heavy industry, has hired an automation and robotics professional as its head of commercial strategy.

In his new position, Michael Perry will focus on building Persona AI’s business development operations, coordinating with strategic partners and helping early adopters of the company’s humanoids. Target customers include offshore platforms, shipyards, steel mills and construction sites.

Perry previously served as vice president of business development at Boston Dynamics, where he led market identification for robotics, and as an executive at DJI. He holds a bachelor’s degree in Chinese and government studies from the University of Texas at Austin.

“Now is the perfect time to join Persona AI as we rapidly close the gap between what’s possible in the lab versus what’s driving real commercial value,” Perry says. “Building industry-hardened humanoid hardware and production-deployable AI is only one piece of the puzzle.”

“Getting humanoids into operations for heavy industry will require the systematic commercial and operational work that makes enterprises humanoid-ready and defining the business case, solving the integration challenges, and building the playbook for safe, scalable adoption,” he adds. “That’s what I’m here to build.”

Rice to lead Space Force tech institute under $8.1M agreement

space deal

Rice University has signed an $8.1 million cooperative agreement to lead the U.S. Space Force University Consortium/Space Strategic Technology Institute 4 (SSTI).

The new entity will be known as the Center for Advanced Space Sensing Technologies (CASST) at Rice and will focus on developing innovative remote sensing technologies.

“This investment positions Rice at the forefront of the technologies that will define how we see, understand and operate in space,” Amy Dittmar, Howard R. Hughes Provost and executive vice president for academic affairs, said in a news release. “By bringing together advanced remote sensing, AI-driven analysis and cross-institutional expertise, CASST will help transform raw space data into real-time insight and expand the frontiers of scientific discovery.

The news comes shortly after the Texas Space Commission approved a nearly $14.2 million grant for the newly created Center for Space Technologies at Rice.

David Alexander, director of the Rice Space Institute, will lead CASST. Alexander is also an inaugural member of the Texas Aerospace Research and Space Economy Consortium and he serves on the boards of the Houston Spaceport Development Corporation, SpaceCom and the Sasakawa International Center for Space Architecture. The team also includes Rice professors and staff Kevin Kelly, Tomasz Tkaczyk, Kenny Evans, Kaden Hazzard, Mark Jernigan and Vinod Veedu, and collaborators from Houston-based Aegis Aerospace, University of California, Los Angeles, University of California, Santa Barbara and Georgia Institute of Technology.

In addition to bringing new space sensor innovation, the team will also work to miniaturize sensors while developing and implementing low-resource fabrication techniques, according to Rice. The researchers will also utilize AI and machine learning to analyze sensor data.

The U.S. Space Force uses space sensors to provide real-time information about space environments and assess potential threats. CASST is the fourth Space Strategic Technology Institute established by the USSF.

“Rice has helped shape the modern era of space research, and CASST marks a bold step into what comes next,” David Sholl, executive vice president for research at Rice, said in a news release. “As space becomes more contested and more essential to daily life, the ability to rapidly sense, interpret and act on what’s happening beyond Earth is critical. This center brings together the materials, engineering and data science innovations needed to deliver that capability."

The USSF University Consortium works with academic teams to develop breakthrough technologies and speed their transition into real-world applications for the U.S. Space Force.

The recent Rice award is part of $16 million over about three years. The USSF also signed a cooperative agreement with the University of Arizona in February.

The consortium has also helped facilitate several technological and commercial transitions over the last two years, including a $36 million commercial contract awarded to Axiom by Texas A&M University's in-space operations team and a follow-on $6 million contract to Axiom to build on technology developed by the University of Texas.
