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.

1PointFive secures new buyer for Texas CO2 removal project

seeing green

Houston’s Occidental Petroleum Corp., or Oxy, and its subsidiary 1PointFive have secured another carbon removal credit deal for its $1.3 billion direct air capture (DAC) project, Stratos.

California-based Palo Alto Networks has agreed to purchase 10,000 tons of carbon dioxide removal (CDR) credits over five years from the project, according to a news release.

The company joins others like Microsoft, Amazon, AT&T, Airbus, the Houston Astros and the Houston Texans that have agreed to buy CDR credits from 1Point5.

"Collaborating with 1PointFive in this carbon removal credit agreement highlights our proactive approach toward exploring innovative solutions for a greener future,” BJ Jenkins, president of Palo Alto Networks, said in the release.

The Texas-based Stratos project is slated to come online this year near Odessa. It's being developed through a joint venture with investment manager BlackRock and is designed to capture up to 500,000 metric tons of CO2 per year. The U.S Environmental Protection Agency recently approved Class VI permits for the project.

DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted. Under the agreement with Palo Alto Networks and others, the carbon dioxide that underlies the credits will be stored in a below-the-surface saline aquifer and won’t be used to produce oil or gas.

“We look forward to collaborating with Palo Alto Networks and using Direct Air Capture to help advance their sustainability strategy,” Michael Avery, president and general manager of 1PointFive, said in the release. “This agreement continues to build momentum for high-integrity carbon removal while furthering DAC technology to support energy development in the United States.”

Houston researchers develop strong biomaterial that could replace plastic

plastic problem

Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic.

The research was led by Muhammad Maksud Rahman, an assistant professor of mechanical and aerospace engineering at the University of Houston and an adjunct assistant professor of materials science and nanoengineering at Rice University. The team shared its findings in a study in the journal Nature Communications earlier this month. M.A.S.R. Saadi, a doctoral student in material science and nanoengineering at Rice, served as the first author.

The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties,” according to the researchers.

Biomaterials typically have weaker mechanical properties than their synthetic counterparts. However, the team was able to develop sheets of material with similar strengths to some metals and glasses. And still, the material was foldable and fully biodegradable.

To achieve this, the team developed a rotational bioreactor and utilized fluid motion to guide the bacteria fibers into a consistent alignment, rather than allowing them to align randomly, as they would in nature.

The process also allowed the team to easily integrate nanoscale additives—like graphene, carbon nanotubes and boron nitride—making the sheets stronger and improving the thermal properties.

“This dynamic biosynthesis approach enables the creation of stronger materials with greater functionality,” Saadi said in a release. “The method allows for the easy integration of various nanoscale additives directly into the bacterial cellulose, making it possible to customize material properties for specific applications.”

Ultimately, the scientists at UH and Rice hope this discovery could be used for the “next disposable water bottle,” which would be made by biodegradable biopolymers in bacterial cellulose, an abundant resource on Earth.

Additionally, the team sees applications for the materials in the packaging, breathable textiles, electronics, food and energy sectors.

“We envision these strong, multifunctional and eco-friendly bacterial cellulose sheets becoming ubiquitous, replacing plastics in various industries and helping mitigate environmental damage,” Rahman said the release.

America's only rare earth producer announces $500M agreement with Apple

Digging In

MP Materials, which runs the only American rare earths mine, announced a new $500 million agreement with tech giant Apple on Tuesday to produce more of the powerful magnets used in iPhones as well as other high-tech products like electric vehicles.

This news comes on the heels of last week’s announcement that the U.S. Defense Department agreed to invest $400 million in shares of the Las Vegas-based company. That will make the government the largest shareholder in MP Materials and help increase magnet production.

Despite their name, the 17 rare earth elements aren’t actually rare, but it’s hard to find them in a high enough concentration to make a mine worth the investment.

They are important ingredients in everything from smartphones and submarines to EVs and fighter jets, and it's those military applications that have made rare earths a key concern in ongoing U.S. trade talks. That's because China dominates the market and imposed new limits on exports after President Donald Trump announced his widespread tariffs. When shipments dried up, the two sides sat down in London.

The agreement with Apple will allow MP Materials to further expand its new factory in Texas to use recycled materials to produce the magnets that make iPhones vibrate. The company expects to start producing magnets for GM's electric vehicles later this year and this agreement will let it start producing magnets for Apple in 2027.

The Apple agreement represents a sliver of the company's pledge to invest $500 billion domestically during the Trump administration. And although the deal will provide a significant boost for MP Materials, the agreement with the Defense Department may be even more meaningful.

Neha Mukherjee, a rare earths analyst with Benchmark Mineral Intelligence, said in a research note that the Pentagon's 10-year promise to guarantee a minimum price for the key elements of neodymium and praseodymium will guarantee stable revenue for MP Minerals and protect it from potential price cuts by Chinese producers that are subsidized by their government.

“This is the kind of long-term commitment needed to reshape global rare earth supply chains," Mukherjee said.

Trump has made it a priority to try to reduce American reliance on China for rare earths. His administration is both helping MP Materials and trying to encourage the development of new mines that would take years to come to fruition. China has agreed to issue some permits for rare earth exports but not for military uses, and much uncertainty remains about their supply. The fear is that the trade war between the world’s two biggest economies could lead to a critical shortage of rare earth elements that could disrupt production of a variety of products. MP Materials can't satisfy all of the U.S. demand from its Mountain Pass mine in California’s Mojave Desert.

The deals by MP Materials come as Beijing and Washington have agreed to walk back on their non-tariff measures: China is to grant export permits for rare earth magnets to the U.S., and the U.S. is easing export controls on chip design software and jet engines. The truce is intended to ease tensions and prevent any catastrophic fall-off in bilateral relations, but is unlikely to address fundamental differences as both governments take steps to reduce dependency on each other.
