From landfills leaking into the water supply to reports of recycling being dropped in landfills, Houston's sustainable future has been mired by waste management faux-pas. According to a fact sheet from the City of Houston, 81 percent of trash in Houston ends up in landfills. Brothers-in-law Chris Wood and Joe Villa co-founded Moonshot Composting in hopes of improving Houston's environmental future.

After the birth of his second child, Wood stepped away from his career as a corporate attorney to stay home and find new opportunities outside of law.

"Just through conversations and reading, it became clear that Houston had not yet picked up the pace on diverting food waste as a city," says Wood.

Composting, a method of decomposing organic solid wastes that's growing in popularity, diverts trash like food and paper towels into compost that can be used to grow plants. While letting your waste have a second life sounds like a sweet deal, it's also a sustainable one. More compost means less waste in landfills, a major contributor to harmful greenhouse gas emissions.

The scarcity of composting options left Wood with answers to what was holding Houston back. Was it the sheer size of the city alone? He reached out to Villa, who had spent 15 years in transportation logistics, with a laundry list of questions.

"How do we minimize a real waste stream that's going to the landfill and maximize streams of materials that we're not using anymore to be reused in some new form or fashion," poses Wood.

It wasn't long before Villa and Wood entrenched themselves in research. The two traveled to South Carolina for the U.S. Composting Council's annual conference last January and left feeling inspired to bring their idea to fruition. Like the rest of the world, they couldn't have anticipated that COVID-19 would rattle the nation in the weeks to come and cause a string of lockdowns across the U.S.

"Even though the pandemic hit before we launched our business, we were far enough along that we felt like we could do this safely," says Wood. A benefit of Moonshot Composting's structure was its drop-off and pick-up style program for both businesses and consumers.

The two co-founders weren't the only people finding a newfound passion for. According to Google Trends, users were searching for ways to compost at home at increased rates after the first stay-at-home order was announced last March. As people were learning to back sourdough and building their puzzle collections, they were also wondering how to be more sustainable in their households. The keywords "composting at home" surged to its greatest peaks during April, July and September in 2020.

With a growth-focused plan to help Houston be greener, Moonshot Composting recently participated in cohort 3 of The Ion's Smart and Resilient Cities Accelerator, where Villa and Wood gained insights from mentors and business leaders.

The momentum has continued with the company's latest release: a digital Diversion Dashboard for residential customers who track their composting totals, compare their composting to other communities, and share the statistics on social media.

"We knew from the time that we started, that there was an opportunity to introduce technology to improve people's behavior around the trash can," says Wood. "Our plan was to operate for at least a year and understand what it's like to help people compost in their business and at home. From the beginning [of our business], we weighed everything we picked up, because we knew that what you can't measure you can't change."

After putting in place a system to weigh each compost pick-up, the two reached out to their network to bring in outside developers.

The proprietary dashboard also translates the weight of compost to residential impact. Looking at Wood's own dashboard, he can see that his compost weighs the equivalent to 168 pineapples and can notice that his neighborhood is ranked second on Moonshot Composting's list of serviceable areas.

A version of the Diversion Dashboard was first made available to commercial subscribers in the spring on a trial basis. Similar to the consumer platform, the commercial dashboard provides carbon equivalencies to compare your environmental impact like pounds of carbon dioxide removed from the atmosphere and "un-driven" miles.

Moonshot Composting's commercial subscribers include Rice University, Houston Baptist University, The Awty International School, ConocoPhillips, Tacodeli, Snooze Eatery, Ostia, and Amli Residential.

Since Moonshot Composting's inception, its subscribing businesses and residents have diverted more than 209 thousand pounds of food waste from landfills.

While the gamification of composting is new, research on the subject is promising. Gamification has been a powerful tool in the consumer technology apparatus for years. Various studies have analyzed the effectiveness of gamification as a self-motivating tool that has a positive impact on health and wellbeing and increases the meaningfulness of an action.

You can drink from a water bottle that awards you for reaching your daily intake, compete with your friends to see who took the most steps using AppleWatches or FitBits, and run miles to earn money for charity. When not enter some healthy competition with your neighbors using the Diversion Dashboard?

When creating the dashboard, Wood and Villa sought to create a fun way to motivate Houstonians to compost and connect with others over their environmental efforts. While cities like Seattle and San Francisco have established city-wide composting program, the co-founders are enthusiastic about expanding a coalition of eco-savvy Houstonians.

"Whether it's good or bad, we [Houston] don't always lead with government mandates, but we always lead with businesses working together with communities to try to do good," says Wood, "We can do it through innovation and that kind of matches the Houston spirit."

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”

Houston startup raises $6M to scale home-based healthcare platform

fresh funding

As healthcare systems race to expand care beyond hospitals and into the home, investors are placing bigger bets on the infrastructure needed to make that shift possible.

This month, Rosarium Health announced it has raised $6 million in seed funding led by Kalos Ventures, with participation from ResilienceVC, Rock Health Capital, Symphonic Capital, Black Tech Nations Ventures and others.

The investment will help the Houston-based startup continue to build its platform, which features a national network of 800-plus clinicians and 3,000-plus contractors to coordinate home accessibility upgrades and modifications for seniors and people living with disabilities.

For founder and CEO Cameron Carter, the company’s mission grew out of firsthand caregiving experiences.

“From my own personal caregiving experiences, I realized that the benefits exist on paper, but not in reality,” Carter said in a news release. “Families are being left to figure out the paperwork and installations all on their own, which shouldn’t be how this works.”

While Medicare Advantage and Medicaid plans have expanded coverage for home-based services and accessibility modifications, the logistics behind delivering those services often remain fragmented.

Rosarium’s platform coordinates the entire process, from clinical assessments and referrals to contractor management, documentation, reimbursement and installation.

“A clinician can document that a home isn’t safe and a plan can approve a benefit, but there’s no one that’s responsible for making sure the work actually gets done,” Carter says. “We built the missing piece.”

The company was founded in 2021 as Rose Health and was a 2023 participant in the Texas Medical Center’s Accelerator for HealthTech program. It has scaled quickly, building a network of more than 800 clinicians and 3,000 contractors across 34 states.

Rosarium is currently in-network for 1.2 million Medicare and Medicaid lives, with projected coverage expected to reach nearly 4 million by the end of the year, according to the release.

“We’re excited to back Cameron because he and the team at Rosarium are building the infrastructure healthcare needs right now to make the home a safe and comfortable place of care,” Kate Ballinger, investor at Kalos Ventures, added in the release.

As part of the recent investment, Ballinger will join Rosarium’s board of directors.

With eyes on the future, Rosarium plans to grow its partnerships with Medicaid and Medicare Advantage plans, including CalViva and Community Health Plan of Imperial Valley, strengthening its presence in California while expanding access to underserved communities.

Additionally, Carter predicts that home-based healthcare will be part of a broader transformation happening across the industry.

“There’s a growing recognition that health outcomes are shaped by what happens in the home,” he said in the release. “The future of healthcare isn’t just treating people after something goes wrong. It’s creating environments that help prevent those problems in the first place.”
