Utilizing the CUSG Energy and Climate Fund, the Environmental Center and Green Labs set out to replace the three most energy-intensive ultra low temperature (ULT) freezers on campus with new, top performing energy-efficient ULT freezers. After looking at what was available on the market, Green Labs proposed and purchased three of a new model of energy efficient PHCBI VIP ECO SMART Series ULT freezer (model MDF-DU703VH/VHA-PA) which is ~30% more efficient per space in the freezer compared to the next most efficient ULT freezers on the market (according to Energy Star data). Furthermore, this particular ULT freezer model received an Outstanding New Product Award in 2023 by a non-profit organization focused on research sample storage, the International Society for Biological and Environmental Repositories (ISBER).

As a result of interest by engaged scientists, instead of just three inefficient ULT freezers, two labs were willing to consolidate samples and retire two additional energy inefficient ULT freezers. Thus, in total, five inefficient ULT freezers that were collectively consuming nearly 170 kWh/day in electricity were replaced with three of these very energy efficient ULT freezers, consuming a combined total of just 15.3 kWh/day. One lab also chose to set the new ULT freezer at -70 ⁰C, which consumes 4.5 kWh/day instead of 5.4 kWh/day at -80 ⁰C, based on manufacturer data.

This one time funding opportunity allowed the Green Labs program to replace five energy inefficient ULT freezers on campus (which were all near the end-of-life) with three very energy efficient ULT freezers utilizing only ~9% of the electricity used by the original five freezers. Having examples of these new efficient freezers on campus is expected to be helpful for energy efficiency efforts as future ULT freezer purchases come up.

CU Boulder recovers helium - a depleting, irreplaceable resource

CU Boulder recovers helium - a depleting, irreplaceable resource Anonymous (not verified) Wed, 02/08/2023 - 00:00

When most people think of helium, they think of balloons, which float as a result of the low density of the inert gas. However, helium has many uses beyond birthday party decorations. Helium plays a critical role in scientific research, medical technology, high-tech manufacturing, space exploration and national defense. Helium’s unique properties – its low boiling point, low solubility, low density and inertness – make it an important resource.

Due to its low density – much lower than air – helium escapes earth’s atmosphere. Most of earth’s helium deposits are underground in natural gas reserves. Unfortunately, according to the American Chemical Society, these finite reserves are being “rapidly depleted.” As a result, there is a need for efficient and economically viable helium recovery.

Luckily, researchers across the world have attempted to offer solutions to this ever-growing problem. At CU Boulder, the physics department operates a helium recycling/liquifying facility that received a CU Green Labs Award in 2022. As researchers in physics and JILA use liquid helium, it is captured and sent back to the shop for re-liquefaction, reducing the amount of helium lost and saving the researchers money.

The physics helium liquefier could become a critical resource for keeping research going on campus through enhanced re-use of helium. The physics helium facility at CU Boulder is paving the way towards a sustainable helium future and serves as an example for other campuses to follow.

CU's helium recycling facility could pave the way towards helium reuse and recovery.

Bring on the green chemistry education, please!

Surveying shows that CU Boulder students want access to green chemistry education as part of their chemistry coursework. To begin to fill that void, a pilot to integrate green chemistry into the introductory chemistry course, CHEM 1021, has been underway since the beginning of the spring 2022 semester. This pilot is being led by two student assistants, Brinn Mcdowell and Jan Hu, and is a collaborative effort between the CU Green Labs Program and the Director of Chemistry Instruction and Associate Chair for Undergraduate Academic Affairs, Matthew Wise, PhD.

So, what is green chemistry? According to the Environmental Protection Agency, green chemistry is defined as "the design of chemical products and processes that reduce or eliminate the generation of hazardous substances."

According to a survey of students in chemistry courses in the fall of 2021, 86% of CU Boulder undergraduates expressed interest in learning about green chemistry and 81% wanted to see more green chemistry topics covered in their chemistry curriculum. 58% of students said they would be interested in taking an additional chemistry course specifically on green chemistry and even more students, 69%, indicated that they would select current chemistry courses offered with a green chemistry emphasis over the courses in their present form. In total, three surveys have been conducted in 2018, 2019, and 2021. See a breakdown of more results here.

The CU Boulder Chemistry Department has already made strides to green many of its chemistry teaching experiments and labs. Modifications to lab experiments have been implemented to cut back on overall waste and the use of toxic chemicals. However, the chemistry lecture classes have yet to be altered which is the focus of the pilot. Thus far, the pilot has successfully demonstrated that student teaching assistants, with education in chemistry, can research and incorporate engaging content on green chemistry into classes. Importantly, this approach minimizes the time commitment required by faculty to work on this integration and provides chemistry student assistants with an outstanding professional development opportunity to apply their skills and knowledge.

If you are interested in learning more about the pilot, attend the 29th Annual Campus Sustainability Summit- Solutions Showcase 2022 where you can learn more about the results of the surveys conducted, the pilot program itself and the impact the program would have on campus if it secures proper funding. With funding for expansion, the pilot program would have the ability to hire student teaching assistants for introductory, general and organic chemistry classes to focus specifically on incorporating and improving the integration of green chemistry into these core chemistry courses. These courses collectively are taken by thousands of CU Boulder students every year from many different majors.

Pilot expansion would have a wide-reaching impact on students while they are getting their education at CU Boulder, but also on what these students choose to do once they graduate, as they would leave CU with the knowledge of green chemistry practices and have the ability to enact change that could have a lasting impact on our future.

Luger Lab wins CU Boulder Freezer Challenge Anonymous (not verified) Tue, 09/25/2018 - 00:00

The Luger Lab, a Biocemistry lab headed by PI Karolin Luger, has won the CU Boulder Freezer Challenge, put on by CU Green Labs.

The CU Boulder competition happened in conjunction with the International Laboratory Freezer Challenge and offered additional prizes to CU Boulder labs participating in the international competition based on how many points they earned on their scoresheets. In all, 23 labs from CU Boulder participated in the 2018 International Laboratory Freezer Challenge and together they earned CU Boulder Honorable Mention in the competition. University of Illinois Urbana-Champaign, who took first prize in the International Freezer Challenge, had 40 labs participate in the challenge.

The Luger Lab earned a $100 gift card to a local restaurant of their choice, and they chose Shamane's Bake Shop.

The following labs also received $100 gift cards to local restaurants of their choice.

2nd place - Biochemistry Cell Culture Facility (defending champions from 2017) - etai's
3rd place - Leinwand Lab - MCDB - The Med
4th place - Detweiler Lab - MCDB - The Corner
5th place - Yin Lab - Biochemistry - Potbelly's
6th place - Parker Lab - Biochemistry - Backcountry Pizza

Labs participated from many different departments on campus including CIRES, Integrative Physiology, Physics, the Institute of Behavioral Genetics and Chemical and Biological Engineering. Labs earn points in the freezer challenge by defosting freezers and refridgerators, sharing freezers between labs, attempting room tempertature sample storage, buying new more efficient UltraLow Temperatures freezers and retiring older, less-efficient models and creating or maintaining inventories of the contents of their freezers and refridgerators.

The International Laboratory Freezer Challenge is organized by the non-profits International Institute for Sustainable Labs (I2SL) and my green lab.

"The freezer challenge is about immediate energy efficiency savings, but it's also about resiliency. Performing this regular maintenance on your systems can prevent catastrophic equipment failures," says Christina Greever, CU Green Labs Program Assistant and Outreach Coordinator. In short, she quips, "it's good for energy efficiency, it's good for your freezer unit itself and it's good for science." Greever adds that labs that participate in the Freezer Challenge are on the cutting edge of finding new research solutions and moving away from the risks to research involved with freezer use.

Congratulations to all participating labs!
