Texas eatery to serve up more eco-friendly burgers

Hearty Austin-based chain Hopdoddy Burger Bar has unveiled a new lineup of regenerative burgers that are supposed to be better for the planet and the consumer.

The term "regenerative burger" could cause a few head-scratches: Some may think of lab-grown or 3D-printed meat, while others think of plant-based alternatives but it’s neither. It is grass-fed meat, sourced a bit differently. "Regenerative farming" is a term used to describe farming and grazing practices that claim to restore and rebuild degraded soil, resulting in better-quality air and water.

Hopdoddy’s vice president of culinary Matt Schweitzer explained that it all began with with a sense of obligation to do better as a brand for the consumers and the ecosystem.

“We felt like we could really take a stand and look to move our entire supply chain in a regenerative fashion, so we could really be proud of the work we’ve done and we could hopefully leave the animals, the farmers, the ranchers, the native grasslands, and our planet a better place than before we started,” says Schweitzer.

The new menu items include the "Roosevelt Burger" with grass-fed regenerative bison; the "Nashville Hot Sandwich" with regenerative raised chicken; the "Regenerative Royale," which is a play on a classic double quarter-pounder with cheese; the "Mother Nature" with grass-fed regenerative beef; and the "Buffalo Bill" also uses regenerative bison, but appears not to be grass-fed.

The five burgers are available at all Hopdoddy locations nationwide. The beef and bison are sourced from Texas-based regenerative company Force of Nature, while the chicken is from Cooks Venture.

With this launch, Hopdoddy removes all plant-based meat substitutes from its menu, significantly reducing the options for vegans and vegetarians. The company felt the ingredients and ethos of the alternative meats — describing some such as Beyond Meats as "falsely advertised" regarding nutrition in a press release — no longer aligned with its values and mission. However, the house-made veggie patty remains on the signature "El Bandito" burger.

Schweitzer says the regenerative burgers have received positive feedback, as people are excited to know where their food comes from, how it gets to their table, and what type of impact it causes. Regarding the future of regenerative meat, he says there is no doubt it could become mainstream soon.

“I think the flavor profile, the eating experience, the story, the mission, the purpose, really speaks for itself," says Schweitzer. "So, I really think it’s a matter of time until 'regenerative' is talked about in the same way that 'organic,' or 'sustainable,' or those type of buzzwords are talked about."

To further show its commitment to regenerative agriculture, Hopdoddy is also one of the sponsors of Common Ground, a documentary about the pioneers of the regenerative movement, premiering October 4 in Austin. The "uplifting" film, according to a release, features well-known actors Laura Dern, Rosario Dawson, Jason Momoa, Woody Harrelson, Ian Somerhalder, and Donald Glover, emphasizing that this motley crew does share one thing in common: a strong belief in regenerative agriculture.

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."
