Trying to make your lab greener? Here are some practical examples of how to reduce your lab's carbon footprint and increase sustainability. Since China stopped accepting certain types of plastic waste from the United States and Europe in 2017, the need to dispose of hundreds of single-use plastic vials and other materials (per researcher, each year!) has created an avalanche of waste.

The "single use" problem

COVID-19 has led to even more single-use plastics in labs – and in our everyday lives. The sheer number of gloves, testing kits and even masks we throw away is incredible. "The majority of masks are manufactured from long-lasting plastic materials, and if discarded can persist in the environment for decades to hundreds of years," wrote authors from the University of Portsmouth at the Conversation.com.

Reduce, reuse, recycle

Labs are full of other single-use plastics such as pipette tips, weighing boats, tubes, flasks, reagent bottles, cuvettes, and more. 'Reduce, reuse and recycle' is a fine mantra, but how do researchers cut down on plastics when the sterility of equipment is a concern?

According to the UK's Chemical and Engineering News magazine, "Different users have optimized washing protocols to get pipette tips clean enough for different lab techniques, including mass spectrometry or toxicology and immunology assays.

Earlier this year, for example, researchers at the National Institutes of Health's National Center for Advancing Translational Sciences found their washed pipettes gave the same results as new tips for preparing small-interfering-RNA screening libraries." Customers of Grenova, a lab equipment firm, have reported that some tips can reused 25-40 times.

Baby it's cold

In Nature, Jyoti Madhusoodanan wrote: "Scientists are increasingly aware of the disproportionate environmental footprint of their research. Academic research facilities consume three to six times as much energy as commercial buildings, much of that due to refrigeration and ventilation systems." The has led some third-party "green companies" employed by labs to hold entire conferences around ultra-low temperature freezers. In a feature advertisement in Nature Portfolio, a statistic read: "An average Ultra-Low Temperature freezer consumes as much energy as a single-family home (~20 kWh/day)."

Help for scientists

There are non-profits that will help you mitigate the amount of waste produced by your lab. One of these, My Green Lab, said on its website: "Run 'for scientists, by scientists,' we leverage our credibility and track record to develop standards, oversee their implementation, and inspire the many behavioral changes that are needed throughout the scientific community."

And it offers a free training course for "ambassadors" – those who would like to guide their lab toward sustainable practices.

Houston biotech VC firm's portfolio cos. score $5.3M in federal funding

money moves

Three portfolio companies of Houston venture capital firm First Bight Ventures have received a combined $5.25 million from the U.S. Defense Department’s Distributed Bioindustrial Manufacturing Program.

“The allocation of funds by the federal government will be critical in helping grow biomanufacturing capacity,” Veronica Breckenridge (née Wu), founder of First Bight, says in a news release. “We are very proud to represent three dynamic companies that are awardees of this competitive and widely praised program.”

The three companies that were awarded Defense Department funds are:

  • Hayward, California-based Visolis, received $2.25 million to plan a facility for production of a chemical that can be transformed into rocket propellants, explosive binders, and sustainable aviation fuel.
  • Alameda, California-based Industrial Microbes received $1.55 million to plan a facility for converting ethanol feedstock into acrylic acid. This acid is a key component used in coatings, adhesives, sealants, lubricants, corrosion inhibitors, and wound dressings.
  • San Diego-based Algenesis received $1.5 million to plan and develop a facility that’ll produce diisocyanates, which are chemical building blocks used to make polyurethane products.

“This award is a testament to our commitment to advancing sustainable materials and will enable us to contribute to both national security and industrial resilience. Our planned facility represents a key step towards securing a domestic supply of critical components for polyurethanes,” says Stephen Mayfield, CEO of Algenesis.

Texas grocer H-E-B finally rolls out digital tap-to-pay services

hi, tech

Texas' favorite grocery store has some good news for shoppers who have a habit of forgetting their wallets. H-E-B is starting a phased rollout for digital tap-to-pay services, starting in San Antonio before spreading to the rest of the chain's stores.

The rollout began Monday, October 7. A release says it'll take "about a week" to spread to all stores in the region before making it ways across Texas. Although it is not known which stores will add the service on what date, the rollout includes all H-E-B stores, including Mi Tienda, H-E-B's Mexican grocery store that has locations in Houston.

With tap to pay, shoppers will finally be able to use smartphone-based systems such as Apple Pay, Samsung Pay, and Google Pay, as well as tapping a physical card.

Payments can be made with those apps, or "digital wallets," at cash registers and self-checkout lanes, as well as restaurants and pharmacies within H-E-B stores. They won't be accepted right away at H-E-B fuel pumps, but customers can use them to pay for gas if they bring their phones to the fuel station payment window.

This isn't exactly cutting-edge technology; Google Wallet launched in 2011, leading the market, and was followed by Apple Pay in 2014. But it's not ubiquitous either. In 2023, a poll by Forbes Advisor found that barely more than half of respondents used digital wallets more than traditional forms of payment.

H-E-B is on a bit of a payment revolutionizing kick, also launching a debit card in 2022 and a partnership in August of 2024 with the H-E-B-owned delivery service Favor for its fastest order fulfillment yet. Central Market and Joe V’s Smart Shop, two other H-E-B brands, also recently launched tap to pay.

“At H-E-B, we’re always exploring a broad range of technologies to enhance how customers shop and pay for products,” H-E-B vice president Ashwin Nathan said in a statement. “This has been one of the most requested services we have received from our customers and partners, and we are excited to now make this popular technology available at all our H-E-B locations.”
