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 researchers harness dialysis for new wastewater treatment process

waste not

By employing medical field technology dialysis, researchers at Rice University and the Guangdong University of Technology in China uncovered a new way to treat high-salinity organic wastewater.

In the medical field, dialysis uses a machine called a dialyzer to filter waste and excess fluid from the blood. In a study published in Nature Water, Rice’s team found that mimicking dialysis can separate salts from organic substances with minimal dilution of the wastewater, addressing some of the limitations of previous methods.

The researchers say this has the potential to lower costs, recover valuable resources across a range of industrial sectors and reduce environmental impacts.

“Traditional methods often demand a lot of energy and require repeated dilutions,” Yuanmiaoliang “Selina” Chen, a co-first author and postdoctoral associate in Elimelech’s lab at Rice, said in a news release. “Dialysis eliminates many of these pain points, reducing water consumption and operational overheads.”

Various industries generate high-salinity organic wastewater, including petrochemical, pharmaceutical and textile manufacturing. The wastewater’s high salt and organic content can present challenges for existing treatment processes. Biological and advanced oxidation treatments become less effective with higher salinity levels. Thermal methods are considered “energy intensive” and susceptible to corrosion.

Ultimately, the researchers found that dialysis effectively removed salt from water without requiring large amounts of fresh water. This process allows salts to move into the dialysate stream while keeping most organic compounds in the original solution. Because dialysis relies on diffusion instead of pressure, salts and organics cross the membrane at different speeds, making the separation method more efficient.

“Dialysis was astonishingly effective in separating the salts from the organics in our trials,” Menachem Elimelech, a corresponding author on the study and professor of civil and environmental engineering and chemical and biomolecular engineering at Rice, said in a news release. “It’s an exciting discovery with the potential to redefine how we handle some of our most intractable wastewater challenges.”

Virtual power plant from Houston-area company debuts at CES

Powering Up

Brookshire, Texas-based decentralized energy solution company AISPEX Inc. debuted its virtual power plant (VPP) platform, known as EnerVision, earlier this month at CES in Las Vegas.

EnerVision offers energy efficiency, savings and performance for residential, commercial and industrial users by combining state-of-the-art hardware with an AI-powered cloud platform. The VPP technology enables users to sell excess energy back to the grid during demand peaks.

AISPEX, or Advanced Integrated Systems for Power Exchange, has evolved from an EV charging solutions company into an energy systems innovator since it was founded in 2018. It focuses on integrating solar energy and decentralized systems to overcome grid limitations, reduce upgrade costs and accelerate electrification.

Regarding grid issues, the company hopes by leveraging decentralized solar power and Battery Energy Storage Systems (BESS), EnerVision can help bring energy generation closer to consumption, which can ease grid strain and enhance stability. EnerVision plans to do this by addressing “aging infrastructure, grid congestion, increasing electrification and the need for resilience against extreme weather and cyber threats,” according to the company.

One of the company's latest VPP products is SuperHub, which is an all-in-one charging station designed to combine components like solar panels, energy storage systems, fast EV chargers, mobile EV chargers and LCD display screens, into a unified, efficient solution.

“It supports clean energy generation and storage but also ensures seamless charging for electric vehicles while providing opportunities for communication or advertising through its built-in displays,” says Vivian Nie, a representative from AISPEX.

Also at CES, AISPEX displayed its REP Services, which offer flexible pricing, peak load management, and renewable energy options for end-to-end solutions, and its Integrated Systems, which combine solar power, battery storage, EV charging and LCD displays.

“We had the opportunity to meet new partners, reconnect with so many old friends, and dive into discussions about the future of e-mobility and energy solutions,” CEO Paul Nie said on LinkedIn.

In 2024, AISPEX installed its DC Fast chargers at two California Volkswagen locations.

Houston-based energy transition leader talks new role, shares future predictions

new hire

For some companies, all that’s needed to make a seismic shift toward innovation is to hire the right person to steer the organization in a transcendent direction.

Arcadis, a sustainable design, engineering, and consultancy solutions company, is channeling this concept by hiring Masjood Jafri as its new National Energy Transition Strategic Advisor and Business Development Lead. In the role, Jafri will help lead and develop the company’s energy transition business growth and strategy for its interests in the United States alongside Matthew Yonkin, National Energy Transition Solution Leader, based in New York.

“I have a fairly diverse background, with about a decade in the energy industry with an oil and gas, power and petrochemicals background,” says Jafri, who moved to Houston from the U.K. back in 2012. “But prior to that, I had about a decade in the infrastructure world, looking into the transportation market, and the manufacturing sector, as well as working as a lender's advisor in the capital market. So, in this very transformative period, you need to connect all the dots.”

With just over six months in his new role, Jafri leverages his 20 years of experience in leading the successful delivery of capital programs and projects as the strategic advisor to Arcadis’ own capital projects.

“Arcadis is on a journey to be the sustainability partner or sustainable transformation partner for our clients,” Jafri says. “And the path to sustainability goes through energy transition. Arcadis has been investing quite heavily in that space for us to be a leading consulting services provider for energy companies.

Jafri’s hire comes as Arcadis moves its business operations in Houston to a new centralized office in the Galleria area. According to Jafri, this will bring the company’s expertise under one roof. With Houston being the energy capital of the world, Jafri says Arcadis is positioned to lead and deliver results for the energy demand in the United States and globally.

“Houston is the Silicon Valley of energy,” Jafri says. “The challenge is to continue to drive with that force. … We have the talent in the city, we have the right mindset—very entrepreneurial, and obviously a lot of capital commitment to make these changes.

“And it is not just coming from the private sector, it is also coming from the public sector. So, I think the stars are aligning in the context of what is needed for us to have a planet-positive future and Houston being suitably positioned to deliver to that,” he adds.

And while keeping up with the demand for energy and moving towards clean energy are equally important challenges, Jafri is more focused on addressing the latter.

“Clean energy is certainly a bigger challenge because it requires a very broad area of energy sources to come together and to make it cleaner,” Jafri says. “Technologically, some of those things are not ready yet, at least to be scalable in a commercial and profitable way. So that's the challenge. I think it is a clean energy challenge, but obviously, the demand side makes it a bit more complicated.”

Texans, and more specifically Houstonians, have seen firsthand the complications of demand and the pitfalls of energy security and resilience. Addressing these issues, along with many other sustainability challenges, will also be part of Jafri’s core mission at Arcadis.

“As we saw in severe climate conditions, the grid is vulnerable and so are the people connected to the grid,” Jafri says. “The better we can make the grid more resilient and more adaptive to these changes, the more satisfactory conditions will be on the ground for people who are affected.”

Jafri asserts that the industry is already considering numerous options, including all colors of hydrogen, solar, wind and geothermal, in addition to fossil-based energy (natural gas). These measures are already in progress, but consumers are concerned with climate change and, of course, the impact on their electricity bills. Still, states like California, Washington and Texas are making progress.

“I would say by the year 2030 you would start to see a pretty significant movement in the right direction,” Jafri says. “If you look from a federal policy perspective, we want to produce 100 percent of the electricity clean by 2035. That is an expected goal, but it’s all happening.”
