Since expanding into Houston just over two months ago, an app that combats food waste has saved over 28,000 meals.

By partnering with locally owned vendors like the Village Bakery, as well as larger chains like Tiff’s Treats, Too Good To Go offers Houstonians a variety of discounted goodies. Users can browse a range of stores and sign up for a “surprise bag,” an assemblage of surplus food that typically costs $5.

The free mobile app now connects savvy shoppers to 130 Houston area stores, allowing them to enjoy food that would otherwise be thrown away. Based in Denmark, Too Good To Go previously launched in Texas in Austin in 2021, before its statewide expansion into Dallas, Houston, and San Antonio in July.

"We are excited to expand our app across Texas to partner with the dynamic food scene and culture," says Chris MacAulay, Too Good To Go US Country Director, in a press release. "In partnership with the incredible local food businesses across Texas, we want to make reducing food waste accessible to all. Together, with the great restaurant community and residents in Texas, we know we will have an immediate impact."

Sarah Soteroff, senior PR manager of Too Good To Go’s North American branch, shared the European based corporation’s scaling up of operations in Texas is part of their plan to move across the United States, going into more cities where food waste persists.

“Our goal is to reduce food waste everywhere that it occurs. So in the long term, we want to eliminate food waste globally,” Soteroff says.

The move into U.S. cities has been gradual, as Soteroff said Too Good To Go works to get an initial network of 50 businesses signed up for the app before officially launching. Beyond getting vendors to list their surplus stock on the app, Too Good To Go representatives aid in marketing and educating the stores on how to use the app.

“We want to make sure that we are setting those businesses up for success and ensuring that consumers know about it through PR, through the stories we share. That businesses do feel as though there’s a value to them for being on the app,” Soteroff explains.

Though the surprise bags are typically priced at about one-third their retail values, vendors can still bring in business through these mystery deals. Roughly 8,500 unique users in Houston have made purchases through the app since it debuted, preventing over 28,000 meals from ending up in landfills.

“For us to ensure that we are able to reduce food waste, we do have to be going into markets like Houston, Dallas, San Antonio, and Austin–in those larger cities where there’s a larger concentration of stores,” Soteroff shares.

According to the Too Good To Go website, every surprise bag purchased prevents the “CO2e emission of charging one smartphone fully 422 times,” and in 2022 the company averted nearly 200,000 tons of CO2e emissions through its community partnerships.

Houston scientists develop 'recharge-to-recycle' reactor for lithium-ion batteries

reduce, recharge, recycle

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.

DOE taps Texas companies for $56M in Strategic Petroleum Reserve deliveries

reserve refill

Two companies with ties to the Houston area have been awarded federal contracts totaling nearly $55.8 million to supply about 1 million barrels of crude oil for the nation’s depleted Strategic Petroleum Reserve.

Houston-based Trafigura Trading will provide two-thirds of the oil, and Dallas-based Energy Transfer Crude Marketing will provide the remaining one-third. Energy Transfer, the parent company of Energy Transfer Crude Marketing, operates a 330-acre oil terminal at the Houston Ship Channel.

The U.S. Department of Energy (DOE), which awarded the contracts, said Trafigura and Energy Transfer will deliver the crude oil from Dec. 1 through Jan. 31 to the Strategic Petroleum Reserve’s Bryan Mound storage site near Freeport.

The Strategic Petroleum Reserve, the world’s largest emergency supply of crude oil, can hold up to 714 million barrels of crude oil across 61 underground salt caverns at four sites along the Gulf Coast. The reserve currently contains 410 million barrels of crude oil. During the pandemic, the Biden administration ordered a 180 million-barrel drawdown from the reserve to help combat high gas prices triggered by Russia’s war with Ukraine.

The four strategic reserve sites are connected to 24 Gulf Coast refineries, and another six refineries in Kentucky, Michigan and Ohio.

“Awarding these contracts marks another step in the important process of refilling this national security asset,” U.S. Energy Secretary Chris Wright said.

In March, Wright estimated it would take $20 billion and many years to fill the Strategic Petroleum Reserve to its maximum capacity, according to Reuters
