With over a billion cars currently on the road — each with four tires that will eventually end up discarded, one Houstonian is hoping to create the infrastructure to sustainably dispose of tire waste now and into the future.

Announced earlier this month, Vibhu Sharma founded InnoVent Renewables to establish production facilities that utilize a proprietary continuous pyrolysis technology that is able to convert waste tires, plastics, and biomass into fuels and chemicals.

In a Q&A with EnergyCapital, Sharma explains his plans to sustainably impact the tire waste space and his vision for his company.

EnergyCapital: Why did you decide to expand the InnoVent brand to focus on renewable energy?

Vibhu Sharma: InnoVent Technology has been developing and implementing projects in renewable energy, chemicals, and oil and gas. Project examples include an EV battery chemical project for a $9 billion chemical company, municipal solid waste (MSW) to biogas, and of course pyrolysis of waste tires, plastics and biomass. Renewable energy is the calling of our time, and with our expertise in this area, we felt strongly that we must do more. With 1 billion waste tires disposed of every year, we wanted to focus on this vast opportunity, which led us to create a spin-off company called InnoVent Renewables, in order to specifically focus on innovative technologies such as pyrolysis of waste tires. We received overwhelming response from our investors and partners, and we're on our way to the first commercial production facility.

EC: Can you describe the process of converting the materials into fuel? How does it work?

VS: At a high level the process involves shredding of tires into small cubes, which are then fed into the main pyrolysis reactor. They're pre-heated enroute to the reactor, using the pyrolysis gas that's generated in the reactor. The reactor operates at a high temperature, and in the absence of oxygen, and decomposes the tires into various components. These are then separated using various techniques. The gases are treated to remove any sulfur, and then used to preheat the shredded tires. The pyrolysis oil (pyoil), which is one of the main products, is condensed out.

The pyoil is further processed to separate out higher value aromatics, and the remaining pyoil is equivalent to off-road diesel or fuel oil, and can be sold directly. The aromatic stream can be further processed or sold directly. It makes a great feed for petrochemical plants, or carbon black plants.

There are two solid products as well. These are recovered carbon black (rCB) and steel wire. Steel wire is separated from the rCB mix and can be sold directly. The rCB is further processed through a series of steps resulting in a high-quality powder which can be used to make tires, making it a completely circular product.

EC: Tell me about your expansion plan. Where are you hoping to grow the company and why in those particular regions?

VS: Our immediate plan is to build and start our commercial production facility in Monterrey, Mexico. Monterrey happens to be home to nearly 50 million waste tires. We are located very close to where the source is. We will set up our initial production train there, and leave room to expand to multiple parallel trains at the same site or nearby sites.

We have our own engineering and operations team in Monterrey, and we have access to modern infrastructure and resources, as this is a fast-growing city of 6 million people. In addition, we have close proximity to Texas for product distribution. Our next step will be to establish production facilities in Texas. We are based in Texas. Texas also has access to at least 50 million tires in landfills all across the state, and the state is taking significant measures to address this issue. We are already engaging with various entities here to plan our expansion site. Meanwhile we have been receiving high levels of interest from counties in Florida, California, as well as international sites in India and the Middle East to set up production facilities there. There are one billion waste tires disposed of every year, it's a huge opportunity. Some of these expansion decisions will depend on support from state governments, access to tires, cost of setting up the facility, etc.

EC: Do you plan on raising investment funding to reach these goals? If not, how will you be funded?

VS: We are fully funded for our first production site in Mexico. Based on our cash flow projections, we should be able to self-fund expansions at that site, and eventually add additional production trains. In order to accelerate our expansion at other sites, we intend to raise funds, with support from different states/counties in the USA where we decide to expand, and with support from investors. We are also open to strategic partners that can team up with us for the expansion both internationally and domestically.

EC:  In the long term, what's the impact you hope to make?

VS: Each production train of 15,000 tons that recycles 1 million passenger tires per year, can reduce CO2 emissions by 80 million pounds per year. Over the next five years, our goal is to get that target to 150,000 tons of recycling, which is 800 million pounds of CO2 emission reduction. That's a good impact to have, and a great way to drive renewable energy forward.

Houston startup strikes deal to develop hydrogen production plant in Canada

hydrogen partnership

Houston-based cleantech startup Vema Hydrogen has reached a tentative agreement with Canada-based CHARBONE Corp. to develop a hydrogen production and processing plant in Québec.

The deal would couple Vema’s production of engineered mineral hydrogen with CHARBONE’s purification, compression and distribution capabilities.

Engineered mineral hydrogen, also known as orange hydrogen, is produced underground by accelerating naturally occurring geochemical reactions in iron-rich rock formations, according to the journal Energy & Environmental Science.

“Across high-value markets — from aviation and maritime fuels to industrial gases — there is incredible demand for Vema’s low-carbon [hydrogen]. Now, more than ever, we need a pathway to deliver these low-carbon fuels,” Pierre Levin, CEO of Vema, said in a news release.

The project would enable Vema to expand into emerging markets like low-carbon maritime and aviation fuel, e-fuels and power generation. Incorporating CHARBONE’s capabilities, the agreement would also support Québec’s hydrogen supply chain.

“The market is demanding high-value industrial gases, and our customers need cleaner, more reliable supply. By pairing Vema’s [hydrogen] feedstock with our purification and distribution capabilities, we’re strengthening Québec’s position as a regional hub for next-generation hydrogen,” Dave Gagnon, CEO of CHARBONE, added in the release.

Vema said in February that it had completed drilling of its first two pilot wells in Québec, making them the world’s first pilot well for orange hydrogen. It’s the first time Vema’s technology has been used outside a lab.

“This pilot will provide the critical data needed to validate [our hydrogen] at commercial scale and demonstrate that Quebec can lead the world in this emerging clean energy category,” Levin said. “The quality of the rock within our core samples is exactly what we expected and is very promising for hydrogen yields.”

Shortly before Vema carried out the pilot drilling, it signed a 10-year deal with California-based energy technology company Verne Power to supply clean hydrogen for California data centers. Over the course of the 10-year agreement, Vema will boost annual production of orange hydrogen to more than 36,000 metric tons.

“There is a robust market for baseload power generation across the U.S., where data centers are straining the grid,” Levin said. “As we power California’s fastest-growing markets with clean hydrogen, we look toward expanding our hydrogen to markets globally and supporting AI-driven power hubs.”

Vema, founded two years ago, raised $13 million in seed funding in 2025.

“The energy transition and emerging uses of hydrogen have spurred demand for clean hydrogen,” Levin said in its funding announcement. “However, existing decarbonized hydrogen production methods simply don’t work — they are too costly and energy-intensive. Vema is here to change that. It’s time to unlock a new era of scalable, low-carbon hydrogen.”
