Researchers Propose Method to Choose More Sustainable Nanomaterials

From the May 1, 2018 edition of Science Daily:  “Engineered nanomaterials hold great promise for medicine, electronics, water treatment, and other fields. But when the materials are designed without critical information about environmental impacts at the start of the process, their long-term effects could undermine those advances. A team of researchers hopes to change that.

In a study published in Nature Nanotechnology, Yale researchers outline a strategy to give materials designers the tools they need to make the necessary assessments efficiently and at the beginning of the design process. Engineers traditionally focus on the function and cost of their products. Without the information to consider long-term environmental impacts, though, it is difficult to predict adverse effects. That lack of information means that unintended consequences often go unnoticed until long after the product has been commercialized. This can lead to hastily replacing the material with another that proves to have equally bad, or even worse, effects. Having materials property information at the start of the design process could change that pattern. “As a researcher, if I have limited resources for research and development, I don’t want to spend it on something that’s not going to be viable due to its effects on human health,” said Julie Zimmerman, professor of chemical & environmental engineering and co-senior author of the study. “I want to know now, before I develop that product.” To that end, the researchers have developed a database that serves as a screening tool for environmentally sustainable material selection. It’s a chart that lists nanomaterials and assesses each for properties such as size, shape, and such performance characteristics as toxicity and antimicrobial activity. Mark Falinski, a PhD student and lead author of the study, said this information would allow researchers to weigh the different effects of the material before actually developing it.”

The database created by the research team also allows other researchers to enter information to improve the material selection framework. It includes engineered nanomaterials and conventional alternatives with human health and environmental metrics for all materials.

The research team includes scientists affiliated with Yale University, the University of Illinois at Chicago, City University of Hong Kong, and the University of Pittsburgh.

Death by Design Screening, August 22 at Champaign Public Library

On Tuesday, August 22, the Illini Gadget Garage will be hosting a screening of the documentary Death by Design at the Champaign Public Library. Doors will open at 6:30 PM and the film will begin at 7:00. The film duration is 73 minutes.

The Illini Gadget Garage is a repair center that helps consumers with “do-it-together” troubleshooting and repair of minor damage and performance issues of electronics and small appliances. The project promotes repair as a means to keep products in service and out of the waste stream. The Illini Gadget Garage is coordinated by the Illinois Sustainable Technology Center.

Death by Design explores the environmental and human costs of electronics, particularly considering their impacts in the design and manufacture stages, bearing in mind that many electronic devices are not built to be durable products that we use for many years. Cell phones, for example, are items that consumers change frequently, sometimes using for less than 2 years before replacing with a new model. When we analyze the effort put into, and potential negative impacts of, obtaining materials for devices through efforts like mining, the exposure to potentially harmful substances endured by laborers in manufacturing plants, and the environmental degradation and human health risks associated with informal electronics recycling practices in various parts of the word, the idea that we might see these pieces of technology as “disposable” in any way becomes particularly poignant. For more information on the film, including reviews, see http://deathbydesignfilm.com/about/  and
http://bullfrogfilms.com/catalog/dbd.html. You can also check out the trailer at the end of this post.

After the film, there will be a brief discussion and Q&A session facilitated by Joy Scrogum, Sustainability Specialist from the Illinois Sustainable Technology Center (ISTC) and project coordinator for the Illini Gadget Garage. UI Industrial Design Professor William Bullock will also participate in the panel discussion; other panelists will be announced as they are confirmed. Professor Bullock is also an adviser for the Illini Gadget Garage project; see more about IGG advisers at http://wp.istc.illinois.edu/ilgadgetgarage/meet-the-advisers/.  Check the IGG web site calendar and Facebook page for room details and panelist announcements.

Admission to this public screening is FREE, but donations are suggested and appreciated to support future outreach and educational efforts of the Illini Gadget Garage. See http://wp.istc.illinois.edu/ilgadgetgarage/donate/donation-form/ to make an online donation and http://wp.istc.illinois.edu/ilgadgetgarage/ for more information on the project.

Reminder: Manuscripts for Special Edition of Challenges Due 12/31/15

challenges-logoManuscripts are still being accepted for the special issue of the journal Challenges, entitled “Electronic Waste–Impact, Policy and Green Design.” 

From the issue’s rationale:

“Electronics are at the heart of an economic system that has brought many out of poverty and enhanced quality of life. In Western society in particular, our livelihoods, health, safety, and well being are positively impacted by electronics. However, there is growing evidence that our disposal of electronics is causing irreparable damage to the planet and to human health, as well as fueling social conflict and violence.

While global demand for these modern gadgets is increasing, policy to handle the increased volumes of electronic waste has not kept pace. International policy governing safe transfer, disposal, reclamation, and reuse of electronic waste is nonexistent or woefully lacking. Where laws do exist about exporting and importing hazardous waste, they are routinely circumvented and enforcement is spotty at best. While European Union countries lead the way in responsible recycling of electronic and electrical devices under various EU directives, most industrialized nations do not have such policies. In the U.S., for example, most electronic waste is still discarded in landfills or ground up for scrap.

It is imperative that we consider how green design practices can address the growing electronic waste problem. This special issue is meant to do just that and spur discussions on how electronic products can become greener and more sustainable.”

If you are interested in submitting a paper for this special issue, please send a title and short abstract (about 100 words) to the Challenges Editorial Office at challenges@mdpi.com, indicating the special issue for which it is to be considered. If the proposal is considered appropriate for the issue, you will be asked to submit a full paper. Complete instructions for authors and an online submission form for the completed manuscripts are available on the Challenges web site at http://www.mdpi.com/journal/challenges/special_issues/electronic-waste#info. The deadline for manuscript submissions is December 31, 2015. Questions may be addressed to co-guest editor Joy Scrogum.

Smartphone Encore Challenge Winners Announced; UIUC Team Runners Up

In a previous post, I promoted a webinar hosted by Net Impact in which the winners of the Smartphone Encore Challenge would be announced, along with an overview of closed-loop strategies at Sprint. You can watch the archived webinar at https://netimpact.org/webinars/the-circular-economy-is-calling-closing-the-loop-in-the-smartphone-industry. (Note that the quality of the video for the winning concept was poor during the webinar; you can view the video separately at https://www.youtube.com/watch?v=fjYyW4i7OS8.) The Challenge was sponsored by Sprint, HOBI International, Brightstar, and Net Impact, and asked students to find profitable and innovative ways to repurpose old smartphones or their components. Participation was limited to the first 25 teams to register. Read more about the Challenge at https://netimpact.org/impact-programs/smartphone-encore-challenge.

SECwinners

I’m pleased that a concept submitted by UIUC students, NEO, was a runner up in the competition. NEO involves the reuse of smartphones as low-cost computers for teaching programming to kids, thus addressing e-waste, digital divide, and education issues simultaneously. This innovative idea was created by Elizabeth Reuter, Kevin Lehtiniitty, and Biplab Deka.

The students came up with this concept for their final project in ENG/TE 498 “Sustainable Technology: Environmental and Social Impacts of Innovations,” which I taught in collaboration with Dr. Brian Lilly and Kirsten Walker in spring 2014. For their final class project, students could either prepare a repair guide for iFixit.com, or create a mock entry for the International Sustainable Electronics Competition, a global student competition administered by SEI which ended in 2013.  The video below was prepared as part of that class project.

The winning concept from students at UC Berkeley, TouchCart, involves using old cellphones to make finding items easier in grocery stores while also allowing scanning of items during shopping. It also allows connection to customer service, and quick check out. The other runners up, StreetSmart from Ohio State University, involves used cellphones as in-car technology to help track driving habits. This would allow insurance companies to more easily reward safe drivers with lower rates. The winning team received $5,000, which can be used toward attending a Startup Weekend to help take their business idea to the next level. And they’ll also receive strategic guidance from executives at Sprint, Brightstar, and HOBI to strengthen the team’s business model.

Despite not winning this particular competition, Team NEO is participating in other student competitions to raise funds to bring this worthy concept to reality. Join me in wishing them all the best in these pursuits, and congratulations for their achievements thus far.

Flame Retardants Continue to Ignite Controversy

Flame Retardants in Printed Circuit Boards Partnership IconDuring Pollution Prevention Week back in September, I wrote a post for the Great Lakes Regional Pollution Prevention Roundtable (GLRPPR) Blog on the environmental and human health impacts of flame retardants. In that post I talk about decisions by major health systems to stop purchasing furniture treated with flame retardants in response to the adverse effects associated with many of these chemicals, and describe the compounds as an illustration of the importance of employing source reduction and safer alternatives during product design and manufacture.

Recently, flame retardants have been in the news again in the last few months, as 16 companies and organizations signed the Center for Environmental Health (CEH) Purchaser’s Pledge, committing to specify and purchase furniture products that meet flammability standards without the use of chemical flame retardants.

Recent research has shown that Michigan’s bald eagles are among the most contaminated birds on the planet when it comes to phased-out flame retardant chemicals in their livers. Despite being phased-out, the flame retardants in question are persistent and bioaccumulative, meaning that top-predators like eagles continue to deal with exposures from the past.

Additionally, on December 15th, the US EPA Design for Environment Program announced an updated draft report of the DfE Partnership to Evaluate Flame Retardants in Printed Circuit Boards.

From the DfE web site: “The purpose of this alternatives assessment is to provide objective information to help members of the electronics industry more efficiently factor human health and environmental considerations into decision-making when selecting flame retardants for PCB applications. This draft assessment provides updated human health and environmental information on flame retardant alternatives to tetrabromobisphenol-A (TBBPA) for use in circuit boards. TBBPA is one of the most commonly used flame retardants for printed circuit boards in electronics. The report includes a description of differences in combustion by-products from burning printed circuit boards containing alternative flame retardants at temperatures simulating uncontrolled recycling or incineration. In parallel with this draft assessment, industry trade groups tested alternative non-halogenated flame retardants and found that they function equally as well or better than TBBPA-based circuit boards for certain products.”

This updated draft assessment is available for public review and comment until February 15, 2015.  There’s still time to provide your input. Please submit comments to Docket NO. EPA-HQ-OPPT-2014-0893 via www.regulations.gov.

For more information on the DfE draft assessment, see http://epa.gov/dfe/pubs/projects/pcb/, or contact Emma Lavoie.

Smartphone Encore Challenge Seeks Innovative Reuse Concepts

The International Sustainable Electronics Competition ended in 2013 after inspiring students around the world to consider ways to extend the useful life of electronic devices. Now SEI is happy to witness the launch of another sustainable electronics student competition–this one focused on the reuse of smartphones or smartphone components. smartphone-encore-challenge-logo-v02

Sprint, in collaboration with HOBI International, Brightstar, and Net Impact, have announced the Smartphone Encore Challenge.

From the competition web site: “Millions of smartphones get discarded each year as consumers upgrade to new models. The old phones get tucked away in drawers or thrown away, burdening landfills. According to the EPA, only about 10% of phones in the U.S. are reused or recycled. It’s such a waste – these devices are still wonders of technology, with an amazing capacity to capture, process, store, and transfer data. They’re often chock full of features, including an accelerometer, gyroscope, GPS, camera, and more. They’re also an untapped business opportunity…We want you to find profitable and innovative ways to repurpose old smartphones or their components. You get to put your creative and business skills to use addressing an important issue, and, if you win, you’ll get some support to put your idea in motion.”

Specifically, the winning team will receive $5000 which can be used toward attending a Startup Weekend (powered by Google for Entrepreneurs)  to work on the development of their idea. Winners will also receive guidance from executives at Sprint, Brightstar, and HOBI to strengthen their business model. “In addition, the winner and two runners up will be featured in a Net Impact ‘Issues in Depth’ webinar on Earth Day. They’ll also present their business ideas to sponsor executives through a videoconference, and will be highlighted in a national press release from Sprint.”

Sounds pretty cool, right? Well, if you’re interested, there are a couple of important points to note. First, participants need to be members of the Net Impact student community. Simple enough–it’s free to join. Next, be aware that students can choose to participate as individuals or as members of teams.

Most importantly, participation in the competition is limited to the first 25 registrants. Full details, including the registration form, are available on the competition web site.

Those lucky 25 will be shipped an entry kit containing:

  • Two (2) pre-owned Android smartphones for reference and prototyping — the devices will be fully activated with voice, text, and data for the length of the contest
  • List of device features/capabilities and guidance on disassembly/repair
  • List of estimated costs for the device as well as voice, text and data connectivity to help price your product
  • A consent form that all members of the team will need to sign and return
  • Pre-paid shipping label to return the devices at the end of the competition

Each team (or individual registrant) will develop a product concept and business pitch (and optionally a brief video). These ideas must be submitted by March 27, 2015, at 11:59 pm PT.

Expert judges will select one winner and two runners up, based upon criteria outlined on the competition web site.

So put your thinking caps on, students. Your solution might just become a reality.
