ASU’s sustainability headquarters goes zero waste

April 11, 2015

zero-waste-wrigley-sustainabilityby Alex Slaymaker, Master’s of Sustainable Solutions

The Julie Ann Wrigley Global Institute of Sustainability is now equipped with a system capable of achieving zero waste, defined as 90 percent diversion from landfills.  The system offers the option of recycling, composting, TerraCycling, plastic film and bag recycling, and landfilling “waste” – a term now nullified as all materials diverted from the landfill are valuable resources.

This seemingly complex five-option system is viewed as standard in many countries around the world, including Germany and Japan.

The opportunity to practice what is preached at the sustainability headquarters of ASU requires students, staff and faculty to learn how to properly use the zero waste system. In order for Wrigley Hall inhabitants and visitors to see these bins as empowering rather than overwhelming, graduate student zero waste advocates held a Zero Waste Kick-Off Party on April 9. The celebration on the first floor of Wrigley Hall helped to raise awareness about the new zero waste pilot, eliminate myths about “waste” and educate on proper diversion practices.

New finding: trees grow on money

April 10, 2015

tree-lined-street-shade-kpg_payless-182392325By the time we reach adulthood, most Americans have come to understand that money doesn’t grow on trees. But a new study published in PLOS ONE this month shows that trees do – figuratively speaking – grow on money.

Christopher Boone, dean of the School of Sustainability at Arizona State University, was among the authors of the study. The article resulted from a workshop led by Boone at the National Center for Ecological Analysis and Synthesis.

“We studied seven cities across the U.S.,” says Boone. “What we found was a correlation between low-income neighborhoods and low-density tree cover.”

Study finds link between excess nutrients and ecosystem impacts

April 9, 2015

arianne-cease-diets-ecosystemA study led by ASU sustainability scientist Arianne Cease demonstrates how human food production can have a profound impact on ecosystems.

For example, phosphorous is commonly added to foods as a preservative, leading to an excess in waste streams. It can also run off and enter the water supply when waste is used as fertilizer in agriculture. When there is an imbalance of nutrients like phosphorous entering bodies of water, toxic algal blooms may result.

“These algal blooms can contaminate drinking water and reduce water clarity, oxygen levels and biodiversity,” said Michelle McCrackin, a researcher at Stockholm University (Sweden) and a member of Cease’s team.

Cease’s study shows that new ways of recycling nutrients to fertilize crops, along with upgrades to waste treatment facilities to remove more nutrients like phosphorus, could substantially reduce water pollution.

Study explores heat-mitigating technologies for urbanizing region

March 27, 2015

urban-heat-population-growthA new study led by sustainability scientist Matei Georgescu reveals some of the dynamics at play as one region of the country, the Central Valley of California, braces for substantial population growth and all it entails. The study, based on computer simulations of rural to urban land conversion, shows that as areas of California grow and develop, the resulting built environment could generate additional heat.

Georgescu used ensemble-based simulations employing EPA projections of urban growth to assess urban expansion climate effects by the year 2100 in the Central Valley. He first assessed the resulting rise in regional temperatures and then explored several temperature mitigating strategies for buildings: cool roofs, green roofs and hybrid approaches. He found that as the state deploys temperature-mitigating technologies, there are secondary effects that appear to take place, such as less daytime air turbulence, which could lead to higher concentrations of pollutants.

But the urban heat island effect can be mitigated using new technologies and the latest in sustainable design techniques, said Georgescu, whose “Challenges associated with adaptation to future urban expansion” appears in the April 1 issue of the Journal of Climate. Finding the right combinations of technologies and techniques will be key.

ASU engineer works to improve computer sustainability

March 26, 2015

harvesting-excess-computer-heatArizona State University computer scientist Carole-Jean Wu is gaining attention for her work to improve the energy efficiency of both large- and small-scale computing nodes, encompassing everything from desktop processors, smartphones and other mobile devices to business-scale data centers.

Wu’s research focuses on designs for chip-multiprocessors and heterogeneous computing systems, energy-efficient smartphone architecture and architectural energy harvesting techniques for modern computing nodes. Rather than allowing superfluous heat generated by devices to reduce performance speed, Wu decided to harvest it with a thermoelectric generator, which converts heat to electricity using a phenomenon called the Seebeck effect.

Wu’s paper, “Architectural Thermal Energy Harvesting Opportunities for Sustainable Computing,” recently received the Best of Computer Architecture Letters (CAL) award.

Happily Ever After: Storytelling and the Long View

Thought Leader Series

March 25, 2015

A Thought Leader Series Piece

By Ed Finn

Ed FinnNote: Ed Finn is the founding director of the Center for Science and the Imagination at Arizona State University, where he is an assistant professor with a joint appointment in the School of Arts, Media and Engineering and the Department of English.

The story goes that when beetles were discovered in the eaves of the great hall at New College in Oxford, everyone began wondering where they could possibly find replacements for the gigantic timbers that had held up the roof for hundreds of years. They needed oak trees almost as old as the building itself. As it turned out the founders of the college had planted oaks expressly for the purpose of repairing structures, with university foresters protecting them over generations. The great hall was completed in the late 1300s, and they were building something that they intended to last functionally forever.

Today it seems like the expected lifespan of a building is getting shorter, not longer. More alarmingly, our perception of time seems to be narrowing—we forget our history just as readily as we ignore the future.

Project aims to strengthen resilience of Southwest infrastructure

March 24, 2015

infrastructure-resilience-sustainabilityUsing a three-year $600,000 grant from the Water Sustainability and Climate program, ASU engineers and sustainability scientists Mikhail Chester and Thomas Seager are leading a project that will provide a guide to boosting the resilience of infrastructure systems against potential threats posed by climatic changes.

Seager will work on developing one of the key methods the project team hopes will encourage foresight in policymaking and planning for these infrastructure networks. Using Arizona as a case study, Seager will devise a game-based learning platform – specifically a computer game – to educate leaders about possible future infrastructure vulnerability issues and how to approach the task of assessing what can be done to deal with them sooner rather than later.

The work based at ASU’s Sustainable Urban Systems Lab, which is directed by Chester, will focus primarily on desert regions because they are especially vulnerable to environmental impacts brought on by climate-related factors.

Urban ecologists study human-nature interactions

March 19, 2015

Urban-Ecology-CAP-LTERIn the latest installment of the “Sustainable Cities” series, Senior Sustainability Scientist Nancy Grimm discusses common misconceptions about ecologists and nature. She presents the idea of untouched wilderness as an example.

“We’ve recognized that there really aren’t such places, or are very few such places, left on Earth,” says Grimm, an ecologist herself who has worked in the field for more than 30 years.

Grimm is also the director of Central Arizona-Phoenix Long-Term Ecological Research, a project launched in 1997. CAP LTER is one of 26 LTER sites throughout the United States. Based at ASU, it is one of only two sites that examine urban ecosystems. Specifically, the Phoenix site answers questions about ecosystem services – benefits provided to people by the environment or wildlife – and studies how humans interact with nature in their cities.

Scholars seek sustainable solutions through environmental humanities

March 6, 2015

environmental-humanitiesIn an effort to improve prospects for generations to come, a group of ASU scholars in the emerging discipline of environmental humanities is addressing humanity’s struggle to think in the long term. The team, which includes sustainability scholars Sally Kitch and Joni Adamson, approaches its work using a combination of humanistic scholarship and scientific research. Their aim is long-term, human-centered solutions that truly transform the way we live and think.

“We have technological advances that could go a long way to solving some of these problems. But we aren’t implementing them,” says Kitch. “We don’t have the political or social will to make the kinds of dramatic changes in our values, in our sense of comfort and well-being in the world, that are really required if we’re going to get off of the fossil fuel gravy train that shapes our current political and economic systems.”

Kitch, Adamson and others are working toward their goal through activities like leadership in the international Humanities for the Environment project, which houses its North American Observatory Branch at ASU.

Lithium-ion battery life to be extended through ASU research

March 5, 2015

longer-battery-lifeASU researchers are exploring new energy storage technology that could give the lithium-ion battery an even longer life. By combining a high-performance silicon electrode architecture with a room temperature ionic liquid electrolyte containing the new bis-fluorosulfonylamide anion, the researchers establish a highly energy-dense lithium-ion cell with an impressively long cycling life. In fact, it maintains greater than 75 percent capacity over 500 charge/discharge cycles with almost no wasted electrons.

“This study brings home the fact that energy storage technology still has a lot of room to run, with new technological changes coming at a fast pace,” says Dan Buttry, professor and chair of ASU’s Department of Chemistry and Biochemistry. “This is important when considering areas where storage is important, such as grid storage and electric vehicles.”

Scientist encourages inclusion in technologies development

March 4, 2015

david_hayden_disability_technologyIn anticipation of a Future Tense event on technology and the future taking place in Washington, D.C., Senior Sustainability Scientist Sethuraman Panchanathan explores the subject in Slate magazine. His article, titled “The best adaptive technologies are designed by, not for, people with disabilities,” illustrates this point using ASU graduate David Hayden as an example. Hayden, who is visually impaired, used his disability to develop an assistive tablet called the Note-Taker – a technology that his sighted peers were also eager to use.

“Truly revolutionary technologies require engagement with users throughout the design and development process. While it’s helpful to get feedback and ideas from focus groups on users’ needs, short sessions don’t give us a full understanding of the challenges and opportunities in developing assistive technology solutions,” writes Panchanathan. “It is imperative that people with disabilities play a leading role in envisioning, conceptualizing, developing, implementing, deploying, testing, and validating potential solutions, tools, and technologies.”

In a November 2014 Thought Leader Series Piece, Ray Jensen made a similar point about the importance of including disabled persons, particularly from a sustainability standpoint.

Arizonans view water as top priority, according to new ASU poll

February 27, 2015

morrison-cronkite-poll-waterA new poll, conducted by ASU’s Morrison Institute for Public Policy and the Walter Cronkite School of Journalism and Mass Communication, articulates the top two priorities among Arizona residents: education and water.

The inaugural Morrison-Cronkite Quarterly Poll surveyed 754 Arizonan adults statewide to assess opinions on a variety of issues, from law enforcement to arts and culture. Among the 11 issues offered to respondents, “maintaining adequate water and water quality” ranks at that same level of importance (87 percent) as education.

“It’s apparent that the importance of ensuring an adequate and quality water supply for Arizona’s varied interests figures prominently on Arizonans’ radar,” said David Daugherty, associate director of Morrison Institute and director of the poll. “This is a complex and dynamic issue, but clearly one that Arizonans understand as a priority that needs to be thoroughly examined and addressed.”
