Vibhu Sharma observed a huge sustainability problem within the automotive industry, and he was tired of no one doing anything about it.

"Globally, humans dispose 1 billion tires every year," Sharma says on the Houston Innovators Podcast. "It's a massive environmental and public health problem because these tires can take hundreds of years to break down, and what they start doing is leaking chemicals into the soil."

Today, 98 percent of all tires end up in landfills, Sharma says, and this waste contributes to a multitude of problems — from mosquito and pest infestation to chemical leaks and fire hazards. That's why he founded InnoVent Renewables, a Houston-based company that uses its proprietary continuous pyrolysis technology to convert waste tires into valuable fuels, steel, and chemicals.

While the process of pyrolysis — decomposing materials using high heat — isn't new, InnoVent's process has a potential to be uniquely impactful. As Sharma explains on the show, he's targeting areas with an existing supply of waste tires. The company's first plant — located in Monterrey, Mexico — is expected to go online early in the new year, an impressive accomplishment considering Sharma started his company just over a year ago and bootstrapped the business with only a friends and family round of funding.

"It's about 16 months or so from start to commercial operations, which is phenomenal when you consider what it takes to build and operate a chemical or petrochemical facility," Sharma says.

Currently, with the facility close to operations, Sharma is looking to secure customers for the plant's products — which includes diesel, steel, and carbon black — and he doesn't have to look too far out of the automotive industry for his potential customer base. Additionally, the plant should be net zero by day one, since Sharma says he will be using the output to fuel operations.

While the first facility is in Mexico, Sharma says they are already looking at potential secondary locations with Texas at the top of his list. Houston, where Sharma has worked for 26 years, has been a strategic headquarters for InnoVent.

"When it came to doing the research and development, we were able to work with experts in the Houston and Texas areas to test out our idea and validate it," Sharma says. "One thing that gets under appreciated about Houston is how well it's connected to the rest of the world. There are so many direct connections between Houston and Latin America, as well as Europe, Middle East, and Asia."

"I also find that the Houston ecosystem is very supportive of new companies and helping them grow," he adds.

2 Houston student teams to compete in Shell’s international eco-friendly driving challenge

Off to the races

What started as a bet in the '30s has evolved into the Shell's Eco-marathon. The competition challenges high school and college students to engineer the fuel-efficient vehicles. And at this year's Shell Eco-marathon Americas, two teams will be representing Houston.

Students from Rice University and James E. Taylor High School are competing in the Shell Eco-marathon Americas, which begins April 3 and wraps up April 6. This year's competition is being held at Sonoma Raceway in Sonoma, California, and will include more than 90 teams from high schools and colleges throughout North and South America.

That's a far cry from the competition's origins. Shell's first fuel efficiency competition took place in 1939, when two Illinois scientists struck a friendly bet over who could engineer a vehicle that ran the furthest on a gallon of gas. The company held an employee competition that year and, save for around a decade and a half in the '70s and '80s, the competition has been held in some capacity every year.

"We really needed to get more young people interested in technology careers," says Pam Rosen, general manager of the Shell Eco-marathon. "It [doesn't] even need to be with Shell. It's more about the method, science, and helping [students[ gravitate toward those opportunities."

The Shell Eco-marathon has adapted with the decades. Students design vehicles that run on gas, diesel, and biofuels, as well as batteries and electricity. Vehicles fueled by GTL (gas-to-liquid) and hydrogen have also competed in the Eco-marathon, Rosen says.

"It kind of ebbs and flows toward what we see the automotive manufacturers trending toward," Rosen says.

The teams from Rice University is a returning presence to the Eco-marathon, while the team from James E. Taylor High School is competing in the Eco-marathon for its first time. Both teams engineered battery-powered electric urban concept vehicles, Rosen says, and describes "urban concept vehicles" as being similar to Smart cars.

The team that takes the top prize in the Americas' urban concept vehicle competition will compete in the Eco-marathon's regional qualifiers in London. As for the lucky winner? They'll head to Italy, where they'll get to drive their vehicle on the racetrack used in the San Marino Grand Prix in Marino, Italy, Rosen says.

UH med school granted $2M gift to offer student scholarships

scholarship gift

A new scholarship endowment aims to support students in the University of Houston’s recently established medical school.

The University of Houston’s Tilman J. Fertitta Family College of Medicine received a planned estate gift commitment estimated at $2.1 million to establish the Bob Diehl and Teresa Evans Diehl Scholarship Endowment. The scholarship will assist full-time medical students who demonstrate financial need and meet academic standards.

“Endowed scholarships like this do more than ease the burden of tuition—they empower our students to focus on learning, leadership and compassionate care,” Jonathan McCullers, UH vice president of health affairs and dean of the Fertitta College of Medicine, said in a news release. “We are deeply grateful to the Diehls for their vision and commitment to expanding access to health care through education.”

The endowment aims to provide annual scholarship support for students enrolled in the Fertitta College of Medicine. The gift also aligns with the university's fundraising initiative focused on expanding opportunities for students, known as Can’t Stop Houston: The Centennial Campaign, which works to expand research ahead of UH’s 100th anniversary next year.

The Diehls are both graduates from UH, and Bob Diehl spent 38 years working at UPS.

“It brings me happiness to know that my endowment will make a difference in young people's lives and in the communities that will need those future doctors,” he said in the release.

The Fertitta College of Medicine welcomed its inaugural class of 30 students in 2020 and expects classes to grow to 120 students in the coming years, according to UH. The university believes scholarship opportunities will be crucial for students to pursue medical education despite financial challenges.

“The Diehl family’s generosity will open doors for talented future physicians who are called to serve our communities but may otherwise face financial barriers to pursuing a medical education,” McCullers added.

Houston medtech firm secures $30M for neurosurgical robot

stroke surgery

Robotic neurosurgery is an exciting new frontier in medicine, and Houston-based medtech firm XCath is leading the charge with its revolutionary Iris robotic system. The company announced in March that it had secured $30 million in Series C funding to continue developing systems to tackle blood clots in the human brain.

“We are grateful to our investors for their conviction in our shared mission to improve clinical outcomes for patients impacted by endovascular diseases,” Eduardo Fonseca, CEO of XCath, said in a news release. “In 2025, the XCath team advanced the frontiers of endovascular robotics. This funding accelerates our commitment to expanding access to life-saving care so that where a patient lives no longer determines whether they live.”

XCath–which also has campuses in Pangyo, South Korea–has already achieved a number of remarkable firsts in robotic neurosurgery. The Iris is the only endovascular robotic system currently in development to perform intracranial navigation or neurointerventional treatment, and is the only robot in the world to have performed an intracranial neurovascular procedure involving the robotic manipulation of three devices.

These new Series C funds, which bring the company's total investment to $92 million, will go toward developing a clinical telerobot capable of performing a mechanical thrombectomy. This would bring unprecedented accuracy and precision to the surgical removal of brain clots, significantly reducing the risk of neurosurgery.

“Robotic surgery succeeds when innovation is paired with practical execution,” Dr. Fred Moll, chairman of the XCath board of directors, said in the release. “XCath has built a promising technology foundation, and just as importantly, a team that values rigor and appreciates perspective. I’m excited to support them as they take on the mission of globalizing access to gold-standard care for stroke patients.”

In November 2025, the Iris debuted under the control of Dr. Vitor Mendes Pereira at The Panama Clinic in Panama City, alongside local Principal Investigator Dr. Anastasio Ameijeiras Sibauste. It was only the second time in human history that a robot had been used for intracranial neurovascular intervention, and it established Iris as a viable technology in the fight against stroke.

“Treatment of stroke and other neurovascular diseases represents one of the most significant financial opportunities in healthcare, supported by positive reimbursement dynamics and strong demand from health systems,” Nicholas Drysdale, CFO of XCath, added in the release. “With our continued investor support and disciplined capital deployment, XCath is positioned to build a category-leading platform in endovascular robotics”.
