The City of Houston announced that it has entered into a three-year partnership with Kentucky-based Rubicon with the goal of improving its waste, recycling, and heavy-duty municipal fleet operations.

According to a statement, the city has installed the company's RUBICONSmartCity platform on the Solid Waste Management Department’s 391 vehicles, and has trained the workforce on using the SaaS software.

“Partnering with Rubicon will help our great city optimize its solid waste operations and make it possible for us to digitize our entire waste and recycling management system,” Mayor Sylvester Turner said in a statement. “The City of Houston is committed to providing the highest level of service to its residents and this partnership will allow us to provide better services, save taxpayer dollars, and deliver a better quality of life for Houstonians.”

RUBICONSmartCity is a cloud-based suite that will allow the department's workforce to track key metrics about pickup, including issues at the curb and recycling contamination, as well as information about its fleet of vehicles. The platform includes a mobile app, an onboard data collection device, and a web-based portal.

The city envisions that information collected by RUBICONSmartCity will enhance reporting tools used by 311 and give the department a better understanding of what's happening in the field.

“The City’s Department of Solid Waste can use this information to advise and educate residents around service scheduling, best practices for waste and recycling management, and reduce costly return trips,” Solid Waste Management Department Director Mark Wilfalk said in a statement. “These insights, alongside route optimization and digitization efforts, are set to deliver an optimal operation to the City of Houston.”

RUBICONSmartCity is used in more than 70 cities across the U.S., including San Antonio. The product was the focus of a 2021 Amazon documentary entitled "The Road to Zero Waste," which focused on Rubicon's work in Santa Fe, New Mexico.

“Our partnership with the City of Houston is off to a fantastic start, as we were able to install our products and train the entire Solid Waste Department’s workforce in only 73 days, an incredibly fast turn for such an undertaking,” Michael Allegretti, Chief Strategy Officer at Rubicon, said in a statement. "This partnership comes at a critically important time, as Houston and other cities across the nation look to maintain, and ultimately expand, service levels.”

In August 2021, the City of Houston also launched HTX Collects, a mobile app aimed at helping residents keep track of weekly services, updates, and waste collection days. At that time, the city estimated that it collected curbside service for over 395,000 residential homes within the city limits.

Family-owned composting startup redesigns how Houston disposes of waste

don't worry, be happy

Jesse Stowers has always strived to do his part for the environment. From recycling and making eco-conscious choices, the Stowers were doing everything right, but was it enough?

The family of five was throwing away two trash bags of waste a day that would later end up in landfills until Stowers stumbled on composting as a solution. In May, he launched Happy Earth Compost, a company set on making Houston more sustainable.

If you're unfamiliar with composting, get ready for a crash course. Composting is a sustainable method of decomposing organic solid wastes and turning that waste into compost, a substance that helps plants grow. Food scraps and household items like rice, pasta, meat, poultry, fish, vegetables, fruits, coffee grounds, spoiled food, and tea bags are just a few of the many things that can be composted rather than thrown away.

"Your food waste and compostable waste is anywhere from 25 to 50 percent depending on the family," explains Stowers. According to Happy Earth Compost, one human creates an estimated 1,642 pounds of trash each year.

When looking at striking statistics, it's clear composting has a direct impact on the future of our environment. In Houston, 81 percent of waste ends up in landfills that pile high, and the city exceeds the national waste average by 25 percent. While the smell of landfills may make you wince, the repercussions of exhausting those landfills are even more displeasing.

Not only are the plots of land permanently lost from agricultural and home development, but the landfills also emit methane gas, a greenhouse gas that's 28 times more potent than carbon dioxide, according to The Independent.

What started as the Stowers family's resolution to be eco-friendly became a full-blown business plan. After Stowers attempted to compost at home for his own family, he soon partnered with New Earth Compost in Fulshear, Texas, as a drop-off location for the waste and did a test drive of the service with his neighbors back in March. Happy Earth Compost now serves 350 homes in the Greater Houston-area and has plans to expand to College Station.

Happy Earth Compost has created a service, with pricing ranging from $15 to $35, that provides Houstonians with the bins to compost and picks up the waste from your door. The buckets can be picked up weekly, bi-weekly or monthly while the company does all of the labor and dirty work to help you compost. A new $5 drop-off option is also available for Houstonians who are willing to drive to one of the applicable farmers' markets.

Subscribers can also get free compost to use in their gardens, what gardeners often call "black gold" because of its value and benefits, says Stowers.

The family-owned business' typical week involves picking up buckets from 300 houses, dropping off compost, cleaning those buckets, and starting the process all over again.

"It's not the most glamorous thing, but it's getting people set up to do it. We're trying to make things easy for everybody by doing the hard work on our end," he says.

Ease is a key feature that helps the service stand out to Houstonians. Composting in Houston no longer requires the personal labor of investing in a compost bin, balancing the mixture of materials, measuring the temperature of your compost, and ordering worms to help accelerate the process (you read that right).

At various farmers' markets around Houston, Stowers is quick to point out the convenience of the program he's created. "It's hard to convince people to compost. It's easier to convince them to try something that's beneficial and simple," he explained.

Jenna Arbogast, a Happy Earth Compost customer, had dabbled in composting on her own but never committed to maintaining it at home. "When I found out about Happy Earth Compost, I so excited that someone was taking the initiative to extend this city-wide. Being that we are such a large city, we have such a great opportunity to heal our environment," says Arbogast. "I really love contributing to something as a collective. Even though I could compost at home, I really wanted to support this initiative," she says.

To Arbogast, who has been using the service for three months, convenience and transparency have made Happy Earth Compost a joy to work with. "You get all the benefits of composting without the maintenance, and you're supporting a good cause," she says.

Since its May launch, the Happy Earth Compost Instagram has grown by over 1,900 fans. The Stowers family has been amazed by the response and hopes to expand to more households in Houston.

"I think there's definitely a movement to be more sustainable to actually consider what we're doing and take care of our stuff, including the earth," says Stowers. He envisions a future where composting is taught to future generations as a fundamental need for the environment.

"It may not cost us now, but it will cost us eventually. What can we do now to make a difference now?" asks Stowers.

Houston biotech company tests hard-to-fight cancer therapeutics

fighting cancer

A Houston-based, female-founded biotech company has developed a treatment that could prove to be an effective therapy for a rare blood cancer.

Cellenkos Therapeutics has completed promising Phase 1b testing of its Treg cell therapy, CK0804, in the fight against myelofibrosis. According to a news release from the Cellenkos team, the use of its cord-blood-derived therapeutics could signal a paradigm shift for the treatment of this hard-to-fight cancer.

Cellenkos was founded by MD Anderson Cancer Center physician and professor Simrit Parmar. Her research at the hospital displayed the ability of a unique subset of T cells’ capability to home in on a patient’s bone marrow, restoring immune balance, and potentially halting disease progression.

Myelofibrosis has long been treated primarily with JAK (Janus Kinase) inhibitors, medications that help to block inflammatory enzymes. They work by suppressing the immune response to the blood cancer, but don’t slow the progression of the malady. And they’re not effective for every patient.

“There is a significant need for new therapeutic options for patients living with myelofibrosis who have suboptimal responses to approved JAK inhibitors,” Parmar says. “We are greatly encouraged by the safety profile and early signs of efficacy observed in this patient cohort and look forward to continuing our evaluation of the clinical potential of CK0804 in our planned expansion cohort.”

The expansion cohort is currently enrolling patients with myelofibrosis. What exactly are sufferers dealing with? Myelofibrosis is a chronic disease that causes bone marrow to form scar tissue. This makes it difficult for the body to produce normal blood cells, leaving patients with fatigue, spleen enlargement and night sweats.

Myelofibrosis is rare, with just 16,000 to 18,500 people affected in the United States. But for patients who don’t respond well to JAKs, the prognosis could mean a shorter span than the six-year median survival rate outlined for the disease by Cleveland Clinic.

Helping myelofibrosis patients to thrive isn’t the only goal for Cellenkos right now.

The company seeks to aid people with rare conditions, particularly inflammatory and autoimmune disorders, with the use of CK0804, but also other candidates including one known as CK0801. The latter drug has shown promising efficacy in aplastic anemia, including transfusion independence in treated patients.

The company closed its $15 million series A round led by BVCF Management, based in Shanghai, in 2021. Read more here.

Pioneering Houston biotech startup expands to Brazil for next phase

On the Move

Houston biotech company Cemvita has expanded into Brazil. The company officially established a new subsidiary in the country under the same name.

According to an announcement made earlier this month, the expansion aims to capitalize on Brazil’s progressive regulatory framework, including Brazil’s Fuel of the Future Law, which was enacted in 2024. The company said the expansion also aims to coincide with the 2025 COP30, the UN’s climate change conference, which will be hosted in Brazil in November.

Cemvita utilizes synthetic biology to transform carbon emissions into valuable bio-based chemicals.

“For decades Brazil has pioneered the bioeconomy, and now the time has come to create the future of the circular bioeconomy,” Moji Karimi, CEO of Cemvita, said in a news release. “Our vision is to combine the innovation Cemvita is known for with Brazil’s expertise and resources to create an ecosystem where waste becomes opportunity and sustainability drives growth. By joining forces with Brazilian partners, Cemvita aims to build on Brazil’s storied history in the bioeconomy while laying the groundwork for a circular and sustainable future.”

The Fuel of the Future Law mandates an increase in the biodiesel content of diesel fuel, starting from 15 percent in March and increasing to 20 percent by 2030. It also requires the adoption of Sustainable Aviation Fuel (SAF) and for domestic flights to reduce greenhouse gas emissions by 1 percent starting in 2027, growing to 10 percent reduction by 2037.

Cemvita agreed to a 20-year contract that specified it would supply up to 50 million gallons of SAF annually to United Airlines in 2023.

"This is all made possible by our innovative technology, which transforms carbon waste into value,” Marcio Da Silva, VP of Innovation, said in a news release. “Unlike traditional methods, it requires neither a large land footprint nor clean freshwater, ensuring minimal environmental impact. At the same time, it produces high-value green chemicals—such as sustainable oils and biofuels—without competing with the critical resources needed for food production."

In 2024, Cemvita became capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant. As a result, Cemvita quadrupled output at its Houston plant. The company had originally planned to reach this milestone in 2029.
