MOSCOW, Idaho — Idaho researchers may have found a new, green technology that is perfectly suited for cleaning up environmental messes: yarn. Scientists at LCW Supercritical Technologies in Moscow and the Pacific Northwest National Laboratory have found that acrylic fiber is highly effective at extracting uranium from seawater.

President of LCW Supercritical Technologies Chien Wai said the experiments led him to wonder how this material would do extracting other heavy metals, such as those found at high levels in polluted mining sites. Wai said it turns out yarn works very well for this process, too.

"If we can use this cheap material to clean up the contaminated streams, waterways, that would be a great environmental remediation technology,” Wai said.

Wai said there are even more applications for acrylic strands of fiber picking up heavy metals, such as filters for cleaning lead out of drinking water. The experiment extracting uranium from seawater was made possible through a grant from the U.S. Department of Energy and could get a large-scale test in the Gulf of Mexico.

Wai said he would like to have the opportunity to test the material for environmental remediation and is still waiting on that chance. Along with being effective, Wai underscored how cheap the process is.

"We even get the sweaters from Goodwill and that's 100% acrylic fiber - used sweaters - and they work just as well,” he said. “So you can think that this making waste into a wonderful material for environmental applications."

Wai noted even more possibilities for acrylic fiber, such as picking up vanadium, which is important in battery and steel production, and extracting precious metals like gold and silver. The next step for researchers is scaling the technology up for commercial use.

A survey of 760 registered Latino voters found 87% of Latinos support projects to produce a cleaner, natural world.

The poll, conducted in 10 states, including Illinois, was commissioned by the Hispanic Access Foundation. The organization creates outreach efforts to inspire individuals to improve themselves, their families and their communities.

Vanessa Muñoz, waterways program manager for the Hispanic Access Foundation, said the survey showed disparities and injustices in the Latino community and is designed to empower community leaders' push for change and boost issue awareness. She noted the survey's timing is crucial.

"We are in an election year," Muñoz emphasized. "The survey results can play a critical role in shaping and informing policy discussions and ensuring that the needs and perspective of Latino voters are considered in the electoral process."

Among those surveyed, 91% of Latinos support policies for future Congressional sessions such as new national monuments, national parks or wildlife refuges to protect areas for outdoor recreation.

Environmentalists are seeing an increase in Latino advocacy in the challenge to clean up U.S. land and waters, especially in the Mississippi River area.

Muñoz explained one goal is the Biden Administration's 30 by 30 plan, which calls for conserving 30% of America's lands, fresh water and oceans by the year 2030.

"We found that 86% of Latinos think that PFAS or forever chemicals are a major threat to the Mississippi River," Muñoz outlined. "Another one was that 93% of Latinos believe that trash dumped in rivers and streams is a major threat to the Mississippi River."

Other survey respondents were based in Arkansas, Iowa, Kentucky, Louisiana, Minnesota, Mississippi, Missouri and Tennessee.

Public comment ends this week for a permit needed for a high-profile oil pipeline project in northern Wisconsin. Opponents, including tribal voices, as well as supporters, have laid out recent organizing efforts ahead of an application decision. The U.S. Army Corps of Engineers will eventually decide on an environmental permit sought by Canadian firm Enbridge to re-route a section of its Line 5 pipeline around the Bad River Reservation. Tribal leaders have been engaged in a legal fight with the company over its existing line, which currently covers 12 miles of reservation land.

Gussie Lord, Earthjustice managing attorney of the Tribal Partnerships Program, represents the tribe and says the new plan fails to ease concerns.

"We know that this reroute is not a solution. It's a false solution to the dangers of the current pipeline. In fact, it really extends the dangers of the pipeline and increases the threat of a devastating oil spill, both to the Bad River Reservation's watershed and Lake Superior watershed," Lord explained.

Her group and other environmental organizations say more than 150,000 comments are being submitted that reflect these concerns. A separate coalition of labor, business and agricultural groups says it gathered roughly 14,000 signatures in support of the re-route. Ahead of public comment closing tomorrow, the coalition sent a letter arguing the construction would be a big economic win, with the new line aiding regional propane supplies.

Some supporters tout the potential jobs and related benefits.

Jason Wilhite, activism team lead with the outdoor apparel company Patagonia, contends any major spill could harm water recreation and all the business activity it creates.

"Put simply, a rupture of the Line 5 pipeline would have a devastating impact on our regional economy," he explained.

In an emailed statement, Enbridge said it's committed to extensive protective measures to minimize and mitigate project impacts. Tribal advocates say they are especially worried about the potential effect on wild rice beds. It's not clear when the Army Corps of Engineers will decide on the application. Other permits are needed for the proposed re-route.

A new project is set to help North Carolina communities address environmental justice and climate equity.

The city of Charlotte, in collaboration with environmental groups, is launching the GreenPrints Initiative - to promote sustainable housing, improve air quality and develop green infrastructure in under-resourced neighborhoods.

CleanAIRE NC is among the key organizations involved.

According to the group's community engagement coordinator Kennedy Williams, the initiative's goal is to address the lack of sustainability and educate communities that need it the most - and are often overlooked.

"A lot of people are experiencing issues related to climate change that they don't know what climate change is or necessarily what sustainability looks like," said Williams. "So making sure that we're introducing sustainability and then also making sure that every aspect of every resident's lifestyle has sustainability at its core."

Williams explained that much of the initiative's efforts will be concentrated in what are known as the Opportunity Corridors of Beatties Ford Road and Freedom Drive, as well as Wilkinson Boulevard.

These areas have been identified as priorities for the deployment of sustainable solutions and community engagement.

A key component of the GreenPrints Initiative is air-quality monitoring, a project spearheaded by CleanAIRE NC.

Williams said sensors will be placed throughout the target neighborhoods to provide valuable data to community members, nonprofits and regulatory agencies.

"Low-cost air pollution sensors will be distributed to air keepers, who are basically like volunteer community members who are interested in maintaining air monitoring," said Williams. "The data from these sensors will be available through CleanAIRE's air-keeper dashboard, and this will really help better understand their geographic data and also their environmental data."

Williams noted that the GreenPrints Initiative is not just about implementing changes but also about listening to the community.

CleanAIRE NC plans to hold a forum on October 19 to gather input from residents about their sustainability concerns and priorities, ensuring that the initiative meets the needs of those most affected.
