Dozens of Houston college students tackled circular economy challenges, and two came out on top by winning the top award.

University of Houston’s Energy Transition Institute hosted a challenge for students to address the issue of plastic waste and create a real-world circular economy, as over 60 students participated in the inaugural Circular Plastics Challenge.

Six finalist teams presented their solutions at the 2023 Energy Night hosted by the UH Energy Coalition with final pitches ranging from transportation emissions, renewable packaging and sustainable material, drones to limit excess packaging, and more topics aimed to reduce use.

Sarah Grace Kimberly and Emma Nicholas were the challenge winners. The team proposed using a liquid-based membrane filter inserted into household drains to combat microplastics found in common personal care products, such as makeup and hygiene items. The membrane’s function would act as a magnet, which would attract and capture microplastics from wastewater in showers and sinks. Both juniors from the C.T. Bauer College of Business also won the viewer’s choice award from their peers.

“We wanted to provide a simple solution to a growing problem,” Kimberly says in a news release. “Before we did this project, we didn’t know that microplastics existed, let alone in our makeup. I didn’t know I was basically putting plastic on my face every single day and washing it off into our drains. Because it’s an unseen problem, it’s hard to address.”

UH’s ETI is an academic research institute that focuses on advancing environmentally responsible energy efforts.

“If you look at the wide variety of proposals and approaches, you can see the complexity of the problem and all the different things that society must consider to find solutions,” ETI Founding Executive Director Joe Powell says in the release. “I think circularity in plastics and chemicals is as difficult to address as the net-zero issue within the energy sector, if not more. We have a unique opportunity here to tackle both, and it’s really great to see our students thinking ahead.

Other finalists included Wolff Center for Entrepreneurship seniors Nicolas Einarsson, Bennett Mainini, Arianna Chavarria, and Fernanda Ruelas, who secured second place with their renewable packaging company presentation titled “ShipSafe.”

Reverse Logistics — with team members Hasti Seraji, Farzane Ezzati, and Haowei Yang — earned third place for their consumer-driven reverse logistics approach to recycling packaging.

Investment bank opens energy-focused office in Houston

new to hou

Investment bank Cohen & Co. Capital Markets has opened a Houston office to serve as the hub of its energy advisory business and has tapped investment banking veteran Rahul Jasuja as the office’s leader.

Jasuja joined Cohen & Co. Capital Markets, a subsidiary of financial services company Cohen & Co., as managing director, and head of energy and energy transition investment banking. Cohen’s capital markets arm closed $44 billion worth of deals last year.

Jasuja previously worked at energy-focused Houston investment bank Mast Capital Advisors, where he was managing director of investment banking. Before Mast Capital, Jasuja was director of energy investment banking in the Houston office of Wells Fargo Securities.

“Meeting rising [energy] demand will require disciplined capital allocation across traditional energy, sustainable fuels, and firm, dispatchable solutions such as nuclear and geothermal,” Jasuja said in a news release. “Houston remains the center of gravity where capital, operating expertise, and execution come together to make that transition investable.”

The Houston office will focus on four energy verticals:

  • Energy systems such as nuclear and geothermal
  • Energy supply chains
  • Energy-transition fuel and technology
  • Traditional energy
“We are making a committed investment in Houston because we believe the infrastructure powering AI, defense, and energy transition — from nuclear to rare-earth technology — represents the next secular cycle of value creation,” Jerry Serowik, head of Cohen & Co. Capital Markets, added in the release.

Houston cleantech startup Helix Earth lands $1.2M NSF grant

federal funding

Renewable equipment manufacturer Helix Earth Technologies is one of three Houston-based companies to secure federal funding through the Small Business Innovation Research (SBIR) Phase II grant program in recent months.

The company—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—has received approximately $1.2 million from the National Science Foundation to develop its high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial AC units. The company reports that its technology has the potential to cut AC energy use by up to 50 percent.

"This award validates our vision and propels our impact forward with valuable research funding and the prestige of the NSF stamp of approval," Rawand Rasheed, Helix CEO and founder, shared in a LinkedIn post. "This award is a reflection our exceptional team's grit, expertise, and collaborative spirit ... This is just the beginning as we continue pushing for a sustainable future."

Two other Houston-area companies also landed $1.2 million in NSF SBIR Phase II funding during the same period:

  • Resilitix Intelligence, a disaster AI startup that was founded shortly after Hurricane Harvey, that works to "reduce the human and economic toll of disasters" by providing local and state organizations and emergency response teams with near-real-time, AI-driven insights to improve response speed, save lives and accelerate recovery
  • Conroe-based Fluxworks Inc., founded in 2021 at Texas A&M, which provides magnetic gear technology for the space industry that has the potential to significantly enhance in-space manufacturing and unlock new capabilities for industries by allowing advanced research and manufacturing in microgravity

The three grants officially rolled out in early September 2025 and are expected to run through August 2027, according to the NSF. The SBIR Phase II grants support in-depth research and development of ideas that showed potential for commercialization after receiving Phase I grants from government agencies.

However, congressional authority for the program, often called "America's seed fund," expired on September 30, 2025, and has stalled since the recent government shutdown. Government agencies cannot issue new grants until Congress agrees on a path forward. According to SBIR.gov, "if no further action is taken by Congress, federal agencies may not be able to award funding under SBIR/STTR programs and SBIR/STTR solicitations may be delayed, cancelled, or rescinded."

Mars Materials makes breakthrough in clean carbon fiber production

Future of Fiber

Houston-based Mars Materials has made a breakthrough in turning stored carbon dioxide into everyday products.

In partnership with the Textile Innovation Engine of North Carolina and North Carolina State University, Mars Materials turned its CO2-derived product into a high-quality raw material for producing carbon fiber, according to a news release. According to the company, the product works "exactly like" the traditional chemical used to create carbon fiber that is derived from oil and coal.

Testing showed the end product met the high standards required for high-performance carbon fiber. Carbon fiber finds its way into aircraft, missile components, drones, racecars, golf clubs, snowboards, bridges, X-ray equipment, prosthetics, wind turbine blades and more.

The successful test “keeps a promise we made to our investors and the industry,” Aaron Fitzgerald, co-founder and CEO of Mars Materials, said in the release. “We proved we can make carbon fiber from the air without losing any quality.”

“Just as we did with our water-soluble polymers, getting it right on the first try allows us to move faster,” Fitzgerald adds. “We can now focus on scaling up production to accelerate bringing manufacturing of this critical material back to the U.S.”

Mars Materials, founded in 2019, converts captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. Investors include Untapped Capital, Prithvi Ventures, Climate Capital Collective, Overlap Holdings, BlackTech Capital, Jonathan Azoff, Nate Salpeter and Brian Andrés Helmick.
