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.

"What I really feel lucky about is having had the chance to meet and photograph so many people who had a real impact on our lives,” said Christopher Little whose new memoir, “Shooting the Breeze: Memories of a Photojournalist” was just released. The book is as eclectic and colorful as the man himself and offers an intimate look into Little’s globe-trotting career spent behind the lens, capturing some of the most iconic figures, events, and human stories of the past half-century.

In 2021, the Dolph Briscoe Center for American History at The University of Texas acquired Little’s photographic archive.

Cold Spring, a not-so-hidden Hudson Valley gem

“Cold Spring, NY” depicts life in a notable Hudson River town with a rich history and much natural beauty.

According to Alissa Malnati, co-creator of the new coffee table tome, “Cold Spring, NY”, after twenty-five years in the urban jungle, it was time to go in search of a cure for the angst which, for some, can come with metropolitan living. “My husband and I were soul sick,” explained Malnati of the couple’s move to Cold Spring, a Hudson River town located in leafy Putnam County. “We were seeking restoration and quiet, and to be in nature, away from the hustle and bustle of the city.”

The time was right for a move in 2021. The Malnatis relocated from busy Brooklyn to a tranquil mountaintop abode which allowed them to decompress without the intrusion of cell phones and ceaseless city noise. With the shift to the Hudson Valley, Alissa, a writer and fashion executive, and her husband, Will, a podcaster and television producer, found the peace they were searching for in Cold Spring, a semi-rural town known for its boutiques, antique shops, and world-class hiking trails.
