Houston expert shares tips for shrinking your lab's carbon footprint

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.

Building Houston

 
 

Last weekend was a tumultuous one for founders and funders in Houston and beyond. Here's what lessons were learned. Photo via Getty Images

Last week, Houston founder Emily Cisek was in between meetings with customers and potential investors in Austin while she was in town for SXSW. She was aware of the uncertainty with Silicon Valley Bank, but the significance of what was happening didn't hit her until she got into an Uber on Friday only to find that her payment was declined.

“Being positive in nature as I am, and with the close relationship that I have with SVB and how they’ve truly been a partner, I just thought, ‘OK, they’re going to figure it out. I trust in them,'” Cisek says.

Like many startup founders, Cisek, the CEO of The Postage, a Houston-based tech platform that enables digital legacy planning tools, is a Silicon Valley Bank customer. Within a few hours, she rallied her board and team to figure out what they needed to do, including making plans for payroll. She juggled all this while attending her meetings and SXSW events — which, coincidentally, were mostly related to the banking and fintech industries.

Sandy Guitar had a similar weekend of uncertainty. As managing director of HX Venture Fund, a fund of funds that deploys capital to venture capital firms around the country and connects them to the Houston innovation ecosystem, her first concern was to evaluate the effect on HXVF's network. In this case, that meant the fund's limited partners, its portfolio of venture firms, and, by extension, the firms' portfolios of startup companies.

“We ultimately had no financial impact on venture fund 1 or 2 or on any of our portfolio funds or our underlying companies,” Guitar tells InnovationMap. “But that is thanks to the Sunday night decision to ensure all deposits.”

On Sunday afternoon, the Federal Deposit Insurance Corp. took control of SVB and announced that all accounts would be fully insured, not just up to the $250,000 cap. Customers like Cisek had access to their accounts on Monday.

“In the shorter term, the great news is SVB entity seems to be largely up and functioning in a business as usual manner,” Guitar says. “And they have a new leadership team, but their existing systems and predominantly the existing employee base is working well. And what we're hearing is that business as usual is taking place.”

Time to diversify

In light of the ordeal, Guitar says Houston founders and funders can take away a key lesson learned: The importance of bank diversification.

“We didn't think we needed one last week, but this week we know we need a resilience plan," she says, explaining that bank diversification is going to be added to "the operational due diligence playbook."

"We need to encourage our portfolio funds to maintain at least two banking relationships and make sure they're diversifying their cash exposure," she says.

A valued entity

Guitar says SVB is an integral part of the innovation ecosystem, and she believes it will continue on to be, but factoring in the importance of resilience and diversification.

"Silicon Valley Bank and the function that they have historically provided is is vital to the venture ecosystem," she says. "We do have confidence that either SVB, as it is currently structured or in a new structure to come, will continue to provide this kind of function for founders."

Cisek, who hasn't moved any of her company's money out of SVB, has similar sentiments about the importance of the bank for startups. She says she's grateful to the local Houston and Austin teams for opening doors, making connections, and taking chances for her that other banks don't do.

"I credit them to really being partners with startups — down to the relationships they connect you with," she says. "Some of my best friends who are founders came from introductions from SVB. I've seen them take risks that other banks won't do."

With plans to raise funding this yea, Cisek says she's already started her research on how to diversify her banking situation and is looking into programs that will help her do that.

Staying aware

Guitar's last piece of advice is to remain confident in the system, while staying tuned into what's happening across the spectrum.

“This situation that is central to the venture ecosystem is an evolving one," she says. "We all need to keep calm and confident in business as usual in the short term while keeping an eye to the medium term so that we know what happens next with this important bank and with other associated banks in the in our industry."
