The “missing link” in critical minerals may have been in our junk drawers all along, according to new research from the University of Houston.

Jian Shi, an associate professor in the UH Cullen College of Engineering, and his team have unveiled a new supply chain model that aims to make e-waste economically viable and could help make large-scale recycling possible.

Shi, along with professor Kailai Wang and graduate researcher Chuyue Wang, published the work in a recent issue of Nature. Their study outlines how gold, lithium and cobalt from discarded electronics can be kept circulating in the U.S. through the process of “urban mining.” It was supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) through the Vehicle Technologies Office.

The team’s research found that e-waste is the fastest-growing solid waste stream in the world. When waste from smartphones or tablets is left unmanaged, the devices can leak hazardous waste and pose significant fire risks due to aging batteries. Additionally, when they are shipped off to foreign landfills, the U.S. loses the potential to recycle or reuse the critical minerals left inside.

“A lot of people have iPads or old iPhones sitting in their drawers right now, and that’s a waste of a critical resource,” Shi said in a news release. “Urban mining allows us to extract the same high-value materials found in traditional mines without the environmental destruction. More importantly, it helps secure our domestic supply chain for the technologies of tomorrow.”

According to UH, recycling e-waste has not succeeded in the U.S. due to a fragmented recycling system, in which manufacturers, collectors and recyclers operate separately, driving up costs.

The UH team's research looks to change that.

In the study, the researchers modeled streamlined recycling efforts by mapping the interactions between manufacturers and independent recycling markets. Their dual-channel closed-loop supply chain (CLSC) model identified how these players can transition from competitors to partners, which can distribute profits more equitably and make recycling efforts more financially attractive.

According to UH, the research has particular significance due to the growing demand for electronic vehicles and their batteries.

“We can improve the performance of the entire recycling ecosystem and make the profit distribution more balanced,” Wang said in the release. “This ensures that the materials we need for EVs and advanced electronics stay right here in the U.S.”

“By making recycling work at scale, we aren’t just cleaning up waste,” Shi added. “We’re building a foundation that benefits both our national security and our economy.”

Experts from the University of Houston are teaming up with the city on key sustainability efforts.

University of Houston collaborates with county on future-facing sustainability efforts

dream team

Researchers at the University of Houston are partnering with the Harris County Office of County Administration’s Sustainability Office, the Harris County Energy Management Team, and other county staff in an effort to develop a comprehensive baseline of energy use and energy-use intensity that will aim to reduce energy costs and emissions in county facilities.

Once fully established, the team will work on tracking progress and evaluating the effectiveness of energy-saving measures over time. They will begin to build the foundation for future programs aimed at maximizing savings, reducing energy consumption, and increasing the use of renewable energy sources in county operations.

Harris County energy managers, Glen Rhoden and Yas Ahmadi, will work with UH professionals, including:

Jian Shi, UH Cullen College of Engineering associate professor of engineering technology and electrical and computer engineering
Zhu Han, Moores professor of electrical and computer engineering
Xidan "Delia" Zhang, UH research intern

The group began collaborating a year ago, and analyzed energy consumption data from county facilities.They were able to successfully identify key summertime energy-saving opportunities and completed retro-commissioning of four county buildings. Those efforts saved over $230,000 annually in electricity costs.

“This project is a prime example of how impactful research at UH can be when applied to real-world challenges, delivering tangible benefits to both the environment and the communities we serve,” Shi says in a news release.

The team will plan to do additional building projects, which includes the development of solar energy and heat pump initiatives, building automation system upgrades, and LED lighting installations. The goal is to reduce electricity usage by at least 5 percent per year for county facilities by 2030 and cut greenhouse gas emissions by 50 percent over the next 5 years for county buildings.

“Addressing climate change and the energy transition requires a collaborative effort that is not only data-driven and action-oriented but also human-centric,” Shi adds. “It’s about more than just technology—it’s about improving the quality of life for Texans.”

Houston researcher scores $500,000 award to continue on work on energy transition

zeroing in on zero emissions

A University of Houston professor and researcher is laser focused on his work within the energy transition, and National Science Foundation has taken note, awarding him over half a million dollars in funding.

Jian Shi, an assistant professor within the Cullen College of Engineering, recently received the NSF's CAREER award, which will dole out $500,861 in funding through February 2029.

The award was granted for his research, entitled “A Unified Zero-Carbon-Driven Design Framework for Accelerating Power Grid Deep Decarbonization.”

“One of the most major challenges inherent in energy transition is the cost. While reducing carbon emissions serves the best interest of society in the long run, the short-term financial burdens also need to be carefully evaluated to ensure that we have a safe, affordable, reliable and just transition for all,” Shi says in a UH news release. “This challenge has inspired me to work on the innovative framework of “ZERO-Accelerator.”

Shi's ZERO-Accelerator is focused on taking standard carbon-driven tools and integrating them into current power grid operational practices. Shi is the director and founder of SOAR, or the Smart and ZerO-Carbon Energy Analytics and Research Lab.

“It synthesizes interactions from multiple key stakeholders involved in the electricity ecosystem,” says Shi. “The framework considers how to manage carbon allowance allocation and trading for electricity producers, how to maintain a 24/7 zero-carbon power grid for power grid operators and how to enable consumers to understand their carbon footprint and participate in the zero-carbon grid operation.”

In his CAREER proposal, Shi explains that he is also contributing to training the future energy workforce. He adds that he shares this award with his colleagues.

“I believe no accomplishment is truly individual,” he says. “Rather, it is a collective triumph achieved through collaboration, support and shared dedication. As I reflect on the milestones I've reached, I am compelled to express my deepest gratitude to my esteemed colleagues whose unwavering commitment has been instrumental in not just my collective success, but our collective success as well."

Last summer, Shi mentored a UH team in the inaugural American-Made Carbon Management Collegiate Competition, hosted by the U.S. Department of Energy's Office of Fossil Energy and Carbon Management. The team, GreenHouston, took third place in the competition, securing a $5,000 cash prize.

Houston positioned to lead in Carbon Capture Utilization (CCU), study shows

The View From HETI

With global demand for energy production while lowering emissions continues to grow, Houston and the Gulf Coast region are uniquely positioned to lead with carbon capture, utilization and sequestration (CCUS). A new study developed by the Houston Energy Transition Initiative (HETI) in collaboration with Deloitte Consulting explores how the region can transform captured CO₂ into valuable products while supporting continued economic growth and industrial competitiveness.

Key takeaways from the report include:

Houston and the Gulf Coast are uniquely advantaged to utilize and store carbon.As a global hub for chemicals and refining industries, Houston has access to world-class infrastructure, a skilled workforce, and access to global markets. The region also has one of the nation’s highest concentrations of industrial CO₂ and creates the opportunity to capture waste material streams to deliver lower carbon intensity products that continue to deliver economic benefits to the region.

While carbon capture and sequestration (CCS) projects continue to advance, CCU requires coordinated action across policy, infrastructure, technology and market demand to scale successfully. Utilization and sequestration are complementary strategies that support and protect investment deployments. CCS acts as an early foundation while markets and infrastructure evolve toward broader CO₂ utilization, and CCU is essential to developing low-carbon-intensity value chains and products.

“Our collaboration with Deloitte highlights how Houston and the Gulf Coast continue to build on the strengths that have long made our region an energy leader. Houston’s infrastructure, workforce, and industrial ecosystem uniquely position the region to scale CCU,” said Jane Stricker, Senior Vice President, Energy Transition, and Executive Director of HETI. “With supportive policy, continued innovation, and strong industry partnerships, we can accelerate CCU deployment, create new low-carbon value chains, and ensure Houston remains at the forefront of the global energy transition.”

Houston startup raises $6M to grow AI platform for solar, battery contractors

fresh funding

Houston tech startup Artemis has raised $6 million from 10 investors. The company offers an AI-supported platform that enables solar, battery storage and home improvement contractors to design, sell and finance energy projects.

Long Journey and Copec WIND Ventures co-led the round, with participation from angel investor Scott Banister, Coalition Operators, FJ Labs, Ludlow Ventures, Palm Tree Crew, Plug and Play Ventures, Shrug Capital and Tribeca Ventures.

To help propel growth, the company secured $10 million in financing last year (under its previous name, Monalee) from venture debt and growth credit provider Applied Real Intelligence. As Monalee, the company raised $16 million in venture capital.

The company was founded in 2022 as an installer of solar and battery storage projects. Five years later, the startup used in-house technology to establish its standalone software platform as it began pivoting away from installation. The company recently adopted the Artemis brand name.

Artemis says its platform saves time and money for installers of residential solar, battery storage, and energy projects. The platform combines an AI-powered design tool with embedded financing capabilities and compliance automation to create a single operating system.

The company says its customers report as much as a 72 percent reduction in software costs and up to 98 percent faster turnaround times. Thus far, more than 100 installers are using Artemis’ technology.

“Installers shouldn’t need six tools and a week of back-and-forth to sell a project," Walid Halty, co-founder and CEO of Artemis, said in a press release. “This funding gives us the fuel to scale our mission to compress design, financing, and compliance into a single flow so every installer can operate like a modern energy company. We’re not just speeding up deals, we're modernizing how distributed energy gets built.”

The Artemis platform, now available in the U.S. and soon to be launched in Latin America, caters to home improvement contractors, solar companies, lenders, and utilities.

“Artemis is transforming the complexity of distributed energy into elegant simplicity," added Arielle Zuckerberg, general partner at Long Journey.

1PointFive signs latest deal, shares update on $1.3B carbon removal project

DAC deal

Houston-based 1PointFive, a subsidiary of Occidental Petroleum Corp., has secured another buyer of carbon dioxide removal credits for its $1.3 billion STRATOS project as it moves toward operation.

Bain & Company, a Boston-based consulting firm, has agreed to purchase 9,000 metric tons of carbon dioxide removal (CDR) credits from the direct air capture (DAC) facility over three years, according to a news release. DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted.

The deal is Bain's first purchase of DAC removal credits. The company has developed a program that helps clients purchase carbon credits from a range of carbon-removal technologies.

"We are proud to partner with 1PointFive and add them to our portfolio of engineered carbon removal technologies," Sam Israelit, Bain’s chief sustainability officer, said in the news release. "Their track record for developing DAC technology, coupled with their deep understanding of what it takes to deliver large-scale infrastructure projects, uniquely positions them to be a leader in this emerging segment.”

“We believe this agreement demonstrates continued momentum for the solution while supporting the development of vital domestic infrastructure,” Anthony Cottone, president and general manager of 1PointFive, added in the release.

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

The Texas-based STRATOS project is 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 approved Class VI permits for the project last year.

1PointFive says STRATOS is "progressing through start-up activities." The company shared in a LinkedIn post that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.
