Packaging Made With Seaweed

A massive leap towards a future where virgin materials are derived from restorative inputs

Our EcoAlly community is eager to reduce our collective dependence on petroleum for packaging. Enter seaweed: a renewable input that is rapidly gaining attention as a plastic-free packaging feedstock.

EcoEnclose is thrilled to partner with Sway—the leader in seaweed packaging development and innovation—to bring you packaging options that incorporate their seaweed-based flexible films.

Start a Seaweed Packaging Project

Radical collaboration with companies like yours will pave the way for a future in which packaging is derived from seaweed and other regenerative sources. The brands who catalyze this change are visionary — embracing next-generation materials today because they know our planet, people, and wildlife can't afford a plastic-filled future.

Why We Love Seaweed

Brands seeking plastic alternatives have options: corn, sugarcane, potatoes, cassava, rice, wood chips, and more are being used as the feedstocks of commercially available, industrially compostable packaging. However, these options are oftentimes conventionally grown, with little insight into production practices and land use conversion implications of the raw materials being used.
 
Our research has shown that many biobased inputs – particularly when they are conventionally grown – come with important environmental challenges, and some are actually more harmful than the fossil fuels they are replacing.

Feedstock Comparison

Seaweed is truly unique in its spectrum of value chain benefits. Responsible seaweed cultivation can regenerate marine ecosystems, mitigate ocean acidification, and support coastal communities threatened by climate change and overfishing.
 
New science suggests that seaweed can also sequester substantial amounts of carbon. In this way, packaging made with seaweed has the potential to actively replenish ecosystems rather than deplete.

We are thrilled to partner with Sway, a biomaterial innovation company dedicated to moving beyond sustainability and towards regeneration.

Sway seeks to extend the ocean's inherent generosity by pairing seaweed's benevolent qualities with advanced materials science. They are designing next-generation replacements for plastic that replenish seas, soils, and coastal communities.

The seaweed-derived resins and flexible films they are developing are the real deal.

Sway recognizes that scaling seaweed production must be done holistically to prioritize this feedstock’s social and ecological potential.

Sway actively partners with various academic, research, and nonprofit organizations to ensure their success is interlinked with thriving communities and ocean health. Their partners include Lonely Whale, Environmental Defense Fund, 5 Gyres, Seatrees, Native Conservancy, Oceans 2050, the Sustainable Ocean Alliance, and more.

With home and industrial compostability as a mandate for Sway’s entire product portfolio, they rigorously test their films across various compostability and biodegradability standards.
