The City of Houston Solid Waste Management Department is launching a free Food Waste Drop-Off pilot program through the end of February.

The program is in collaboration with Council Member Sallie Alcorn, Zero Waste Houston and the City of Houston Health Department, and allows residents to drop off food scraps at four different locations. The locations are:

  • Kashmere Multi-Service Center, Mondays from 2 to 5 pm
  • Acres Homes Multi-Service Center, Tuesdays from 2 to 5 pm
  • Alief Neighborhood Center, Wednesdays from 4 to 7 pm
  • Sunnyside Multi-Service Center, Thursdays from 3 to 6 pm

Houston residents, businesses, and institutions generate 6.2 million tons of municipal solid waste per year according to the Solid Waste Department program.

“You’ll find when you start composting your food scraps, there is a lot less trash generated in your home, at your curb, and taken to the landfill,” Alcorn says in a news release.

The Solid Waste Management Department provides solid waste services with the collection, disposal, and recycling of discarded material in an environmentally-friendly and cost effective way.

“The Solid Waste Department is eager to continue to provide innovative programs that divert waste from the landfill and actively engage Houston residents,” says Mark Wilfalk, Director of Solid Waste Management in the release.

How this Houston hospital is leading sustainable health care

seeing green

The United States health care sector contributes around 8.5 percent of greenhouse gas emissions, and one Houston hospital is committed to doing its part in reducing the industry's carbon footprint.

Houston Methodist, which recently opened a new tech hub in the Ion in midtown, has put in place several initiatives that reflect a more sustainable future for health care. The organization, which has seven hospitals in the Houston area, revealed some of these ongoing and planned projects at a recent event.

"Houston Methodist is always looking ahead on ways — not only of how we are taking care of patients — but what are we doing to create this environment and making the right efforts for sustainability, which we should all be doing," Michelle Stansbury, vice president of innovation and IT applications at Houston Methodist, says on this week's episode of the Houston Innovators Podcast. "We have to protect this environment that we have or it may not be the same for our children going forward."

The hospital system is currently in the design phase for installing solar panels on the Josie Roberts Administration Building in the Texas Medical Center. This project, in partnership with Houston Methodist's Energy and Facilities workgroup, will be the first step toward renewable energy consumption for the hospital.

Houston Methodist has already rolled out food composting initiatives at its locations in Sugar Land, The Woodlands, and Willowbrook locations — with plans for additional campuses to follow. According to a presentation from Jason Fischer, director of the Office of Sustainability at Methodist, the hospital system has already diverted nearly 100,000 lbs. of food waste from landfills.

Preventing waste recycling or reusing items is another focus of Houston Methodist, Stansbury says, from creating a workflow that enables reusing items that are able to be sanitized rather than thrown away to sustainably getting rid of expired materials. The U.S. has rules about the shelf lives of health care products, but other countries don't have as strict of mandates.

"We're sending (supplies) to other countries that can still use these products," Stansbury explains. "Knowing that we're helping to care for other individuals, to me I think it's very valuable. Other countries don't have the resources that the United States does."

Another notable initiative is incorporating greenspace for patients to enjoy. Houston Methodist is currently in construction on a 26-story hospital tower in the Texas Medical Center that will feature the Centennial Rooftop Garden on the 14th floor.

The Houston Methodist's sustainability team has several other initiatives both ongoing and in the works. More information is available on the hospital's website.

Houston sustainability startup increases Texas impact, diverts 3.5M lbs of landfill waste

the power of composting

Houston-based Moonshot Compost is marking its three-year anniversary this month, demonstrating a successful execution of a sustainable waste management model.

Chris Wood and Joe Villa started the company in July 2020, collecting and measuring food waste in their personal vehicles. Today, Moonshot operates with a team of drivers utilizing its data platform to quantify the environmental benefits of composting.

“People like to compost with us,” Wood said. “When we first started, I don't think we ever thought we would get to so much weight so quickly. We've diverted over 3.5 million pounds of food waste since we launched, and our rate of collection is about 250,000 pounds a month now.”

Moonshot ensures every collection is weighed to calculate its precise impact. Its proprietary system uses QR codes, allowing users to understand both their individual and collective contribution to the composting effort.

Despite starting in the midst of the COVID-19 pandemic, the service has solidly grown. Currently, Moonshot serves 65 commercial and over 600 residential subscribers across Houston, Austin, Dallas, and Waco.

One of Moonshots significant achievements is its Diversion Dashboard, which presents the climate equivalencies of the diverted food waste, highlighting how composting contributes to the reduction of greenhouse gases.

"By composting, you're avoiding landfill methane emissions, which constitute 10 percent of global greenhouse emissions," Wood said.

Moonshot offers subscription programs for both residential and commercial clients. The residential subscription includes a drop-off option for $10 per month or an at-home pick-up service for $29 per month. Each pick-up includes a clean bin exchange. For commercial clients, the base fee is $110 per month, with weekly pick-ups and bin exchanges.

The company's next significant milestone, Wood said, is to divert 5 million pounds of food waste in Houston. As of now, Moonshot expects to reach its 5 million pound goal by mid-2024.

“We think that Houston is sending 5 million pounds of food waste to the landfill every day,” Wood said. “Once we've diverted 5 million pounds in Houston, that'll be the first time that we've diverted a day's worth of food waste in Houston.”

As part of Moonshots most recent compost result update, Moonshot subscribers based in Houston have diverted 3,444,704 pounds of waste from landfills and saved 2,328,366 pounds of carbon dioxide. Visit here for more information on its impact across Austin, Dallas and Houston.

Wood emphasized the importance of changing perceptions on composting: "It’s not disgusting. You already generate food waste at home and work. Composting makes your trash cleaner."

With this mission, Moonshot Compost continues to transform perceptions and practices around waste management and sustainability.

Houston battery recycling company secures $32M in financing

fresh funding

Houston-based Ace Green Recycling has raised $32 million in private investment in public equity (PIPE) financing to support its future plans for growth.

The battery recycling technology company secured the financing with Athena Technology Acquisition Corp. II, a publicly traded special purpose acquisition company that Ace previously announced it plans to merge with. Once the merger is completed, Ace will become a publicly traded company on the Nasdaq Stock Exchange under the ticker symbol "AGXI."

Ace says the financing will be used to complete the merger and scale the company.

“This investment accelerates our mission to redefine battery recycling at a global scale,” Ace CEO Nischay Chadha said in a news release. “At Ace, we are deploying Greenlead® and LithiumFirst™ as a new standard–fully electrified, Scope 1 emissions-free solutions designed to replace legacy processes and unlock a cleaner supply chain for critical materials. We believe that the future of electrification depends on how efficiently and sustainably we recover these resources, and this milestone brings us meaningfully closer to that future.”

Ace says the funding will also be primarily used to fund capital expenditures related to the development of its planned flagship recycling facility, located outside of Beaumont, Texas. According to a February investor presentation, the facility is expected to launch in 2027. It will recycle lead-acid and lithium-ion batteries.

Ace agreed to a 15-year battery material supply agreement with Miami-based OM Commodities last year, in which OM Commodities would supply Ace with at least 30,000 metric tons of lead scrap to be recycled annually. Switzerland-based Glencore plc agreed to a 15-year offtake agreement to purchase up to 100 percent of ACE’s products from four of its planned lead-acid and lithium-ion battery recycling parks back in 2022.

Ace also reported that the funding will be put toward "supporting the expansion of operations and to fund the purchase of other companies," in the release.

Houston AI startup rolls out platform to reshape oil and gas workflows

AI for energy

Houston-based Collide is looking to solve AI issues in the energy industry from within.

Co-founded by former oil roughneck Collin McLelland, the company has developed AI software for operators and field teams, shaped by firsthand oilfield experience. Its AI-native platform “retrieves and synthesizes data from authoritative sources to deliver accurate, cited, and energy-focused insights to oil and gas professionals,” according to the company.

“Oil and gas has a graveyard full of technology that was technically impressive and operationally useless,” McLelland tells Energy Capital. “The reason is almost always the same: the people who built it didn't understand what they were actually solving for. When you're an outsider, you see workflows and try to automate them. When you're an insider, you understand why those workflows exist—the regulatory constraints, the physical realities, the liability concerns, the trust dynamics between operators and service companies.”

Collide’s large language model, known as RIGGS, performed well in recent benchmarking results when taking a standardized petroleum engineering (SPE) exam, the company reports. The exam assesses understanding from conceptual terminology to complex mathematical problem-solving.

According to Collide, RIGGS achieved a score of 67.5 percent on a 40-question subset of the SPE petroleum engineering exam, outperforming other large language models like Grok 4 (62.5 percent), Claude Sonnet 4.5 (52.5 percent) and GPT 5.1 (4 percent).

RIGGS completed the test in 15 minutes, while Grok took two hours. Collide hopes over the next few months, RIGGS will receive a score between 75 percent to 80 percent accuracy.

The software could potentially help oil and gas companies produce accurate outputs and automate trivial workflows, which can open up valuable time for engineers and teams to work on other pressing matters, according to McLelland.

“Collide exists because we sat in those seats — we were the engineers, the operators, the field guys,” he says. ”RIGGS scoring higher on the PE exam versus the frontier labs isn't a party trick. It's evidence that the model understands petroleum engineering the way a petroleum engineer does, because it was built by people who do.”

RIGGS was trained on Collide’s Spindletop hardware and is supported by a vast library of information, as well as a reasoning engine and validation layer that uses logic to solve problems.

“Longer term, we see RIGGS as the intelligence layer that sits underneath every operator's workflow — not a chatbot you open in a browser, but something embedded in the tools engineers already use,” McLelland says. “The goal is to give every engineer the knowledge and pattern recognition of a 30-year veteran, on demand."

According to McLelland, Collide is already building toward reservoir analysis and production optimization, automated regulatory compliance (Railroad Commission filings, W-10s, G-10s), workover report generation, and engineering decision support in the field for near-term use cases. In March, Collide and Texas-based oil and gas operator Winn Resources announced a collaboration to automate the time-intensive process of filing monthly W-10 and G-10 forms with the Texas Railroad Commission, completing what’s normally a multi-hour task in under 30 minutes. Collide reports that Winn’s infrastructure now automates regulatory filings and provides real-time visibility into data gaps, which has reduced processing time by over 95 percent.

“Before Collide, I'd spend hours manually keying in filings,” Buck Crum, director of operations, said in a news release. “(In March), we had 50 wells to file and I was done in 20 minutes. It does the majority of the heavy lifting while keeping me in control. That human-in-the-loop approach saves meaningful time and gives us greater confidence in our compliance and reporting.”

Collide was originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing.” After raising $5 million in seed funding led by Houston’s Mercury Fund last year, the company said it would shift its focus to rolling out its enterprise-level, AI-enabled solution.

Oxy officially announces CEO transition, names successor

new leader

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared last week that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”
