Seaweed

The Box You’re Holding is Groundbreaking!

The window is made with seaweed-based film developed by Sway
The paperboard is 100% recycled, 85% post-consumer waste

How to Dispose

This box is fully curbside recyclable! You can put it – as is – into your recycling bin, and the seaweed-based window will be screened out during the repulping process. As with all windows, staples, labels, and other common additions to paper packaging, non-paper components are screened out during the paper repulping process and landfilled.

The seaweed-based window is home-compostable, meaning it will break down into a healthy soil amendment. For consumers eager to divert landfill waste and who maintain a home compost system or have access to an industrial compost service that accepts compostable packaging, follow these 3 simple steps: (1) remove the window from the box, (2) throw the window in home or industrial compost, and then (3) curbside recycle the box.

Seaweed Film and 100% Recycled Paperboard

Why It Matters

Seaweed is an emerging packaging input with big regenerative potential. Most biobased packaging inputs (such as corn, sugarcane, potatoes, or wood chips) degrade soils, threaten biodiversity, require high volumes of freshwater, result in nitrogen and phosphorus runoff, or rely heavily on fossil fuels for production.

Seaweed is different. Seaweed cultivation requires no land, fresh water, or fertilizers to grow, while actually improving ocean health, strengthening marine life and biodiversity, and improving the livelihoods of the coastal communities.

Seaweed holds incredible promise, and Sway is paving the path towards making this material widely available long-term.

The box you’re holding is an early step in achieving this vision!

Most paperboard packaging is made with virgin solid bleached sulfite (SBS). SBS is cheap, widely available, and prints easily.

Bleached, virgin paper (especially virgin paper that is not FSC Certified) puts tremendous pressure on our ancient and endangered forests, which continue to be logged at an alarming rate worldwide. Destroying trees that are hundreds of years old and disrupting the complex ecosystems they support simply to make a single-use package makes no sense.

Using 100% recycled paperboard helps alleviate this pressure. When compared to virgin paperboard, it also:

  • Emits 74% fewer emissions
  • Uses 52% less energy
  • Requires 33% less freshwater
  • Has a 66% lower impact on ocean acidification

The box you’re holding embodies the importance of choosing circularity over the lowest cost, easiest print material.

EcoEnclose is thrilled to partner with Sway, a biomaterial innovation company dedicated to moving beyond sustainability 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 flexible films they are developing are the real deal: Certified 100% Biobased, home compostable, and scalable.
