Scientists at Purdue University have been experimenting to create adhesives designed to be easier on the environment.

So many products from cellphones and shoes, to furniture and cars all contain adhesives. And because of their petroleum base, there are downsides, as the adhesives may have a strong odor and not be biodegradable when they end up in landfills.

Jonathan Wilker, professor of chemistry at Purdue University, along with his team of chemists found a safer alternative by studying oysters and mussels.

"We take the information we learned from the animals and we create 'biomimetic' adhesives, we call them," Wilker explained. "Surface adhesives that are modeled after biological systems."

Wilker noted like adhesives, sea animals stick to coastal rocks to build their communities. His lab team wanted to make a product just as strong, but also affordable, nontoxic, and sustainably sourced. Wilker's team also had to consider the availability or scale of the materials they started with at the onset of testing.

Research indicates most wood adhesives using petroleum-derived products contain formaldehyde resin. Formaldehyde is already strongly regulated, and more restrictions could be coming in the European market.

Instead, Wilker's formula uses soy oil, mixed with malic acid, a compound which gives apples their tart flavor. He pointed out they have tested it successfully on wood, plastics and metals. Wilker added he is happy to see the interest generated since the findings were published in the journal "Nature," and would like to see more.

"We're looking for partners to help commercialize the technology and actually have an environmental impact," Wilker stressed. "(The) ideal timeline is now; there's no reason to wait. We think we've got it to the point that it's ready to go out."

Future plans for the adhesive are to do further research for possible use in the medical field, as well as for industrial materials and packaging.

Federal data show health care and technology-related jobs are still in high demand but a career in clean energy is now at the top of the list, too, and Wisconsin labor leaders said opportunities are unfolding in the region.

New findings from the Climate Jobs National Resource Center list 82 Wisconsin projects tied to the clean energy transition in the pipeline, which could qualify for tax incentives and key labor standards under the Inflation Reduction Act.

Emily Pritzkow, executive director of the Wisconsin Building Trades Council, said companies behind wind, solar and similar development need to attract workers while adhering to hiring benchmarks.

"Excellent pay, flexibility," Pritzkow pointed out. "And we are rising to meet that."

Labor standards for Inflation Reduction Act projects call for apprenticeships to be offered, so new hires can learn on the job. Pritzkow stressed Wisconsin unions play a big role in carrying out the learning aspect of the hiring boom. There are challenges though, with labor groups noting not enough people are aware of job possibilities and the need for things like affordable housing if a worker has to relocate for their new career.

The Bureau of Labor Statistics lists wind turbine technicians and solar installers as the fastest growing occupations in the U.S. In amplifying messaging, Pritzkow emphasized they have to overcome long-held beliefs only certain other industries, such as dentistry, routinely offer stable employment.

"I think there maybe are some old ideas about what working in the trades means," Pritzkow observed. "These are not temporary jobs. These are meant to be careers."

She added clean energy projects are helping to fuel record demand for apprenticeships. Earlier this year, four major utilities operating in Wisconsin pledged to hire union workers for development spurred by the Inflation Reduction Act. The Climate Jobs National Resource Center estimates the incentives will lead to more than 42,000 union-scale jobs in Wisconsin.

A volunteer program has caught the attention of West Virginia tourism officials.

The Dolly Sods Wilderness Stewards program has been recognized with a "Spirit of West Virginia Award." The program started as a collaboration in 2021 with West Virginia Highlands Conservancy and the Monongahela National Forest.

Dave Johnston, program coordinator, said volunteers are trained to educate visitors on 'leave no trace' principles, trail cleaning and more.

"Taking inventories of campsites and things like that," Johnston explained. "We're basically serving as eyes and ears for the Forest Service for what's going on in the backcountry."

More than 100 volunteers work to preserve and maintain the more than 17,000-acre area in the Allegheny Mountains. According to the International Journal of Wilderness, more states are turning to volunteer groups to maintain trails and collect data, as dollars for the management of federal lands have decreased.

Johnston added the work is important for sustaining protected lands for future generations, noting wilderness areas are specially designated by Congress to remain as pristine as possible.

"They're the most primitive form of public lands that are set aside for people to enjoy in this country," Johnston emphasized.

According to numbers by the West Virginia Highlands Conservancy, an estimated 35,000 people hike and retreat to the Dolly Sods each year.

One of nature's hardest workers is facing extinction from repeated exposure to a dangerous pesticide.

Scientists conducting CT scans reveal neonicotinoid pesticides or "neonics" attack baby bumblebees' brain development and cause neurological damage like paralysis, shaking or death. Use of the chemical introduced in the 1900s has grown globally.

The policy and action group Environment Illinois wants the worst uses of the products banned and removed from store shelves.

Emily Kowalski, outreach and engagement manager for the group, said the chemical is an ingredient in household products and agricultural or industrial applications.

"Neonic pesticides are used on crops but also can be found in some pesticides that are used in home gardens," Kowalski explained. "And are also increasingly being found on coated-on seeds that are being used for farming."

Kowalski added the neonic-coated seeds can contain extremely high chemical concentrations. The global environmental group Greenpeace indicated fruits, nuts, and vegetables and 70% of human food crops are pollinated by bees.

Eleven states have legislation on the books that prohibits the use of dangerous bee-killing products. Illinois is not one of them. In this year's session, lawmakers discussed the "Birds and Bees Act," which would limit the use of neonic pesticides. Kowalski hopes legislators will do more.

"This is a bill that we're supporting, and we are excited to work with legislators to move it forward," Kowalski emphasized. "From the advocacy community, I know there is a lot of appetite to take action, whether it's in this upcoming legislative session, or in looking at the next few years, making sure that Illinois is the next state to protect our pollinators."

The Illinois Department of Natural Resources has cited habitat loss, mites, competition from nonnative species, and diseases as contributors to a declining bee population.
