(Press-News.org) Plastics are firmly entrenched in today’s world thanks to their cheap, light and versatile nature, but the downside is that plastic waste continues piling up. Earlier this year, United Nations Secretary-General Antonio Guterres said that every day, the equivalent of over 2,000 garbage trucks full of plastics is dumped into our oceans, rivers and lakes.
According to the World Economic Forum, the United States only recycled about 6% of the 40 million tons of plastic waste it generated in 2021. Around the world, about 400 million tons of plastic waste is produced each year. Much of it ends up in landfills, oceans and natural habitats, negatively impacting the environment, human health and wildlife. The solution, according to many experts, lies in establishing a sustainable circular plastics economy.
With that in mind, University of Houston’s Energy Transition Institute (ETI) challenged students to address the critical issue of dealing with plastic waste and creating a real-world circular economy. Over 60 students participated in the first Circular Plastics Challenge. The field of competitors was pared down to six finalist teams, who presented their solutions at the 2023 Energy Night hosted by the UH Energy Coalition. The final pitches ranged from renewable packaging and replacing plastic products with more sustainable material to using drones to limit excess packaging, transportation emissions and more.
“If you look at the wide variety of proposals and approaches, you can see the complexity of the problem and all the different things that society must consider to find solutions,” ETI Founding Executive Director Joe Powell said. “I think circularity in plastics and chemicals is as difficult to address as the net-zero issue within the energy sector, if not more. We have a unique opportunity here to tackle both, and it’s really great to see our students thinking ahead.”
BeadBlocker, a team of two students – Sarah Grace Kimberly and Emma Nicholas – was the challenge winner. The team proposed using a liquid-based membrane filter inserted into household drains to combat micro plastics found in many personal care products, such as makeup and hygiene items. The membrane would function as a magnet of sorts, attracting and capturing micro plastics from wastewater in showers and sinks.
The filter, according to Kimberly and Nicholas, not only shines a light on one of the world’s more unheralded yet damaging waste source, but it effectively stops pollution at the source and could significantly curtail the 5.4 million metric tons of micro plastics that enter water annually.
“We wanted to provide a simple solution to a growing problem,” Kimberly said. “Before we did this project, we didn’t know that microplastics existed, let alone in our makeup. I didn’t know I was basically putting plastic on my face every single day and washing it off into our drains. Because it’s an unseen problem, it’s hard to address.”
The idea was so well received that the duo, both juniors at the C.T. Bauer College of Business, also won the viewer’s choice award from their peers, a sign that this could be a small yet highly practical tool in developing a circular economy.
“We’d love to explore any possible options into making this a real thing as opposed to just a concept or idea,” Nicholas said.
Other finalists included:
Wolff Center for Entrepreneurship quartet comprised of seniors Nicolas Einarsson, Bennett Mainini, Arianna Chavarria, and Fernanda Ruelas secured second place with their presentation titled “ShipSafe,” a renewable packaging company dedicated to aiding companies in transitioning to cleaner supply chains.
Reverse Logistics with industrial engineering doctoral students Hasti Seraji, Farzane Ezzati, and Haowei Yang earned third place for their cost-efficient approach to recycling packaging through consumer-driven reverse logistics, involving the return of packaging to distribution centers for repurposing and recycling.
Bottle Caps, an interdisciplinary team – with Guilherme de La Penha, a mechanical engineering senior; Lara Foster, pursuing her M.B.A.; Maryam Amini, pursuing a master’s degree in finance; and Hadi Zanganeh Kia, pursuing a doctorate in atmospheric sciences and meteorology – clinched fourth place. The team’s innovative idea involved replacing plastic bottle and container caps with caps made from PLA/PHB filaments, which are plant-based and biodegradable.
Smart Waste Disposal, with supply chain and logistics technology seniors Vanessa Davis, Karina D., Sardar I., Ronaldo Quiroz, and Munif Momin won fifth place. The team proposed an artificial intelligence-based waste disposal solution that facilitates effective waste separation in public settings, ensuring recyclable materials are kept apart from non-recyclable waste.
Last Mile Delivery comprised of supply chain and logistics technology students Caleb Bihogo (freshman) and Christian Sallese (junior) secured sixth place with their proposal to employ drone technology in the "last mile delivery" of commercial packages to reduce excess packaging and emissions.
Powell is proud of the breadth and depth of the submissions and overall response from students and judges from industry.
“In terms of impact and thinking about circularity and coming up with out-of-the-box solutions, we’re off to a great start at the University of Houston, that’s what we’re here for,” Powell said. “It’s a really complex problem to go after, and I give the student teams credit for putting solutions together and showcasing some really innovative thinking.”
The Energy Transition Institute is an academic research institute focused on advancing reliable, affordable, environmentally responsible energy for all through a just and equity-driven pathway.

Social media influencers may affect more than voter opinions
2023-12-01
UNIVERSITY PARK, Pa. — If Thanksgiving dinner conversations have turned into heated political arguments over the past two decades, social media may be to blame. Popular social media figures — or influencers — who create or share distorted political messages may cause political parties to moderate their policies to win over independent voters in general elections but tend to polarize the rest of society, according to researchers who created a model to study how social media may affect election ...
1 in 8 older adults use cannabis products, suggesting need to screen for risks
2023-12-01
More older Americans use cannabis now than before the pandemic, with 12% saying they’ve consumed a THC-containing substance in the past year and 4% saying they do so multiple times a week, according to a new study of people aged 50 to 80. Those who drink alcohol at risky levels have a much higher rate of cannabis use.
The new findings, published in the journal Cannabis and Cannabinoids Research by a team from the University of Michigan’s Institute for Healthcare Policy and Innovation, suggest a need for more education and screening of older adults for cannabis-related ...
Study identifies peptide as key mediator in heavy alcohol drinking
2023-12-01
(Boston)—Alcohol is the most common addictive substance in the world. Every year in the U.S. excessive alcohol use costs $249 billion and causes approximately 88,000 deaths, as well as various chronic diseases and social issues. Alcohol use disorder, a highly prevalent, chronic, relapsing disorder, affects more than 14 million people in the U.S. alone, in addition to being severely under-treated, with only three modestly effective pharmacological therapies available.
Chronic exposure to alcohol has been shown to produce profound neuroadaptations in specific brain regions, including the recruitment of key stress neurotransmitters, ultimately ...
New understanding of oobleck-like fluids contributes to smart material design
2023-12-01
If you mix cornstarch and water in the right proportions, you get something that seems not-quite-liquid but also not-quite-solid. Oobleck flows and settles like a liquid when untouched, but stiffens when you try to pick it up or stir it with a spoon. The properties of oobleck and other non-Newtonian fluids — including Silly Putty, quicksand, paint, and yogurt — change under stress or pressure and scientists have long struggled to prove exactly why.
Now, researchers at the University of Chicago’s Pritzker School of Molecular Engineering (PME) have used piezoelectric nanoparticles, which themselves change in response to pressure, to investigate the fundamental physics of non-Newtonian ...

Urgent work needed to tackle “substantial” digital health inequality, study recommends
2023-12-01
Millions of people are suffering from digital health inequality because of poverty, experts have warned.
A new study says urgent work is needed to ensure those from deprived areas can access healthcare as the NHS increasingly turns to the use of apps and online health portals for the provision of healthcare.
A team of doctors and academics found a “significant association” between increased poverty and reduced use of digital services. Their modelling estimates that this association accounts for 4.27million patients across England who have not downloaded the NHS app. In October 2022 it was estimated more than 37million patients had activated ...
Unlocking the secret strength of marine mussels
2023-12-01
How do you create strong, yet quick-release connections between living and non-living tissues? This is a question that continues to puzzle bioengineers who aim to create materials that bond together for advanced biomedical applications.
Looking to nature for inspiration, the McGill-led research zeroed in on the marine mussel byssus, a fibrous holdfast, which these bivalve mollusks use to anchor themselves in seashore habitats. The byssus attaches to rocky surfaces using an underwater glue, but the other end (the byssus stem root) is firmly anchored within the mussel’s soft living tissue. This area of contact between the living ...
