Sustainable food packaging

Dear EarthTalk: What’s new in food packaging to make it more sustainable? — E.C., Bern, N.C.

A long with food waste, food packaging is a significant source of pollution, generating approximately half of the packaging waste in the United States. In the wake of growing concerns about climate change and food product packaging’s role in it, companies are taking action to make packaging more sustainable.

There are many changes in progress. Corn and cane sugar plants are being increasingly used as materials for packaging food. However, this system puts pressure on already-stressed agricultural land and can jeopardize food security, since crops that could be used for food itself are being used for other purposes. One solution is to use agro-food residue, the byproduct of agricultural production — cornstarch, rice husks, etc., that would otherwise be discarded — for food packaging. In this way, packaging can reduce agricultural material waste without threatening agriculture or food resources. 

Companies have begun taking the whole life cycle of a product’s packaging, beyond just use and disposal, into consideration. In doing so, they have prompted designs of products made from and transported using sustainable materials, not just ones that can be recycled by customers. For example, Heinz is working with Pulpex to prototype a food-grade bottle made from sustainably-sourced wood pulp that can be recycled and biodegrades if it is thrown away. It has a 90% lower carbon footprint than glass and a 30% lower footprint than PET, a very common type of plastic in food packaging. 

Other examples abound. Alter Eco worked with Natureflex to create truffle wrappers that are made from eucalyptus and birch and then lined with aluminum. The material reportedly composts in industrial settings and biodegrades in the ocean. Boxed Water is Better sells water in recyclable boxes, made of 75% paper that is flattened for shipping, allowing one truck to carry as many boxes to filling centers as 26 trucks carrying plastic bottles. The company also ensures that the paper comes from well-managed forests, that the material is free of BPAs and other chemicals, and that part of the profit is invested in planting trees in deforested and fire-prone areas. Mondelez, which produces snacks like Oreos, and Wheat Thins, Ritz and Belvita crackers, has almost reached its goal of reducing its use of virgin plastic by 25% for rigid packaging and by 5% overall by 2025. 

Such technologies are creating more effective food packaging that reduce waste, but these solutions face obstacles. Investing in sustainable materials and partnering to develop new ideas, combined with the supply chain and inflation disruptions associated with the pandemic, come with potentially-prohibitive financial costs that have impeded some planned transitions. Also, demonstrating the benefits of these changes has proven to be difficult, and “greenwashing” — marketing that overstates companies’ products’ environmental pluses — has made investors wary. However, the chances of success are significant as growing numbers of customers demand sustainable packaging. For example, 24% of young adults have indicated a willingness to pay 5% more for sustainably packaged food.

The artistic life of Joelle Sander

"Flowers" by the late artist and writer Joelle Sander.

Cornwall Library

The Cornwall Library unveiled its latest art exhibition, “Live It Up!,” showcasing the work of the late West Cornwall resident Joelle Sander on Saturday, April 13. The twenty works on canvas on display were curated in partnership with the library with the help of her son, Jason Sander, from the collection of paintings she left behind to him. Clearly enamored with nature in all its seasons, Sander, who split time between her home in New York City and her country house in Litchfield County, took inspiration from the distinctive white bark trunks of the area’s many birch trees, the swirling snow of Connecticut’s wintery woods, and even the scenic view of the Audubon in Sharon. The sole painting to depict fauna is a melancholy near-abstract outline of a cow, rootless in a miasma haze of plum and Persian blue paint. Her most prominently displayed painting, “Flowers,” effectively builds up layers of paint so that her flurry of petals takes on a three-dimensional texture in their rough application, reminiscent of another Cornwall artist, Don Bracken.

Art scholarship now honors HVRHS teacher Warren Prindle

Warren Prindle

Patrick L. Sullivan

Legendary American artist Jasper Johns, perhaps best known for his encaustic depictions of the U.S. flag, formed the Foundation for Contemporary Arts in 1963, operating the volunteer-run foundation in his New York City artist studio with the help of his co-founder, the late American composer and music theorist John Cage. Although Johns stepped down from his chair position in 2015, today the Foundation for Community Arts continues its pledge to sponsor emerging artists, with one of its exemplary honors being an $80 thousand dollar scholarship given to a graduating senior from Housatonic Valley Regional High School who is continuing his or her visual arts education on a college level. The award, first established in 2004, is distributed in annual amounts of $20,000 for four years of university education.

In 2024, the Contemporary Visual Arts Scholarship was renamed the Warren Prindle Arts Scholarship. A longtime art educator and mentor to young artists at HVRHS, Prindle announced that he will be retiring from teaching at the end of the 2023-24 school year. Recently in 2022, Prindle helped establish the school’s new Kearcher-Monsell Gallery in the library and recruited a team of student interns to help curate and exhibit shows of both student and community-based professional artists. One of Kearcher-Monsell’s early exhibitions featured the work of Theda Galvin, who was later announced as the 2023 winner of the foundation’s $80,000 scholarship. Prindle has also championed the continuation of the annual Blue and Gold juried student art show, which invites the public to both view and purchase student work in multiple mediums, including painting, photography, and sculpture.
