Can Maine restaurants get reusable packaging ‘to go’?

The thrift store in your local church’s basement might be doing more for the community than saving families from spending $40 for jeans. Not only can systems of reuse, like thrift stores, reduce waste, they strengthen bonds between neighbors and make communities more resilient to hardship.

“Anytime we see any sort of big economic or cultural shock, a lot of times traditional supply chains are broken,” Dr. Cindy Isenhour said. “But when you have more localized and resilient systems for procurement, they can help you weather those storms.”

Isenhour studies the way that people think about and deal with material waste. With funding from the Mitchell Center, she and Jared Wildwistle, a UMaine Masters graduate, have been studying the feasibility of a different kind of reuse system in Maine: reusable take-out packaging.

Gabby HillyerMudflat meets world: Hillyer’s research reaches a global audience

March 2023

Gabby Hillyer has been a member of the University of Maine community going on seven years, and for approximately five of those years she has been telling and re-telling a story about a stolen bucket. Hillyer is a Ph.D. student in the Ecology and Environmental Sciences program at UMaine. She also participates in the National Research Traineeship Program in Conservation Science and serves as the project coordinator for the Maine Shellfish Learning Network (MSLN), a novel partnership that connects harvesters and others from up and down Maine’s coast to better address the multifaceted issues facing their shellfisheries. Both the MSLN and her graduate research on the coast of Maine emerged from her involvement with an organized effort to strengthen coastal economies at the Mitchell Center. Hillyer has a robust list of accomplishments on her resume, but the bucket drifters always seem to float to the top.

Food wasteCareer Pathways Through Undergraduate Research

January 2023

Katie Tims, Class of 2021, and Dominique DiSpirito, Class of 2022, are recent University of Maine graduates who found promising footholds in the fields of sustainability and materials management in Maine, in part because of their undergraduate research experiences. As interns, both students worked on the Mitchell Center’s Food Waste Management project. The project grew from work started in 2019 by the interdisciplinary Materials Management team to find solutions to Maine’s solid waste problems. In research done by the team, food waste was ranked by stakeholders as a major area of concern. The food waste team collaborates with partners to research and pilot solutions to reduce food waste, keep organics out of landfills, and address food insecurity in Maine.

harvested timberRoger Milliken meditates on the ethics of industry

January 2023

In a talk on November 28, Roger Milliken discussed the conflict between western culture and the sustainability of life on Earth from his unique ethical perspective as a Maine forest manager and environmentalist. Milliken has always had a vested interest in Maine’s forests, partly because its past, present, and future is intertwined with the story of his own heritage. One of Milliken’s core arguments is that the destruction of the natural world and degradation of humans’ quality of life is a result of a western culture rooted in “individualism, separation, and dominion.” Milliken did not pull this claim out of thin air or tabloids, but from his own family’s history.

Graduation capsNew internship program empowers the next generation of sustainability leaders

November 2022

Conjure an image of the prototypical intern: you might imagine a bored 19-year-old fetching coffee and making photocopies, or you might imagine that student struggling to do the work of a full-time professional for free. In these scenarios, interns are either tossed in head-first or beached. Last summer, however, students in the Mitchell Center’s pilot internship program were taught to swim. They were challenged to work with faculty, stakeholders, and each other to tackle real issues facing communities in their backyard, all with the necessary funding, research training and mentorship to promote their success.

Reconnecting Wabanaki Communities to Coastal History

September 2022

Maine’s coast is dotted with over 2,000 shell heaps, sites where Wabanaki ancestors would gather to harvest and eat shellfish, producing deposits of shells ranging in size from small piles to 30-foot-deep mounds. These collections of exceptionally well-preserved materials can help scientists reconstruct a record of past lifeways and environments. For hundreds of years, scientists and industries have extracted a wealth of materials and history from some shell heaps without consultation or collaboration with those whose ancestors created them. As sea level rise accelerates, these losses are compounded by increasing erosion. Dr. Bonnie Newsom is one of the scholars urgently seeking to reconnect Wabanaki people to shell heaps before they disappear forever.

Cultivating Coastal Stewardship in the Damariscotta Estuary

August 2022

Survey the picturesque Damariscotta River and, among the many moorings and oyster farms, you might spot youthful figures hunched over the mudflat, waders on, clam rakes in hand. These are not shellfish harvesters, but local students gathering data to support the sustainable management of an ecosystem and industry.

This summer, Sarah Risley, a UMaine graduate student based at the Darling Marine Center, is leading a team of university and high school students to study the shellfish populations of the upper Damariscotta estuary. They are also recording the local knowledge of harvesters who know the ecosystem the best.

Linda SilkaDifference-making is about risk-taking

July 2022

If all the researchers in a given discipline compiled their peer-reviewed research, what would it amount to? Would it better address the world’s greatest problems, or would it falter?

This is the query Dr. Linda Silka raised this past June, as she stood in front of several hundred members of the Society for the Psychological Study of Social Issues (SPSSI) at their summer conference in San Juan, Puerto Rico. Silka, a Senior Fellow with the Mitchell Center, serves as the President of SPSSI, an organization of 3000+ social and behavioral scientists focused on engaging with the world’s critical social and policy issues from a psychological perspective.

Hand holding clamThe Mudflat: Creating space and making connections to support shellfishing

April 2022

Shellfishing is deeply embedded in the foodways, cultures and traditions of communities all along the coast. This livelihood also contributes significant value to the marine economies and sustenance fishing cultures of coastal areas. Although shellfishing is crucial for many coastal communities, it faces some daunting challenges including water quality problems, increasing pressure from predators like green crabs, shoreline access, and more. How can a new collaborative website help to sustain it?

March 2022

How can we move beyond the notion that there are “others” among “us” and “find a common place that we can all call home”? This is one of the questions that Judy East will explore in her keynote address at the 2022 Maine Sustainability & Water Conference on Thursday, March 31.

Managing the risks of “forever chemicals”

February 2022

PFAS, also known as “forever chemicals” due to their persistence in the environment, are at the center of a growing environmental and public health crisis in Maine, with devastating effects that are being felt across the state. These chemicals have been linked to health problems and have now been detected in well water, farm soils, farm products including milk, wildlife, and people’s bodies in Maine. The Maine Dept. of Environmental Protection reached out to Laura Rickard for help training agency staff in communicating about PFAS risks as part of their overall response to this crisis.
