Easy on the planet
Drop the jug. Skip the PVA.
Here's the whole trip a Just 7 sheet takes, what we can say today, and what we're still testing before we say more.
Overview
The pouch
A thin, flat pouch about 6.4 x 9.6 in, with no plastic window. We're choosing the material now.
The sheet
Pullulan film, made from fermented starch. No PVA.
After the drain
Designed to biodegrade. We're having the finished sheet tested to OECD 301B, the standard lab test.†
Shipping
No heavy jug of water to ship. The pouch is about 1/8 in thick.
Septic systems: we haven't tested that yet, so we're not claiming it.
Planet questions
Is Just 7 plastic-free?
That's the design: a pullulan film instead of PVA, a thin pouch instead of a jug. We'll call it plastic-free once the film specs and the pouch material are confirmed in writing.†
Is Just 7 biodegradable?
It's designed to biodegrade. We're having the finished sheet tested to OECD 301B, the standard lab test, and we'll share the results rather than make the claim early.†
What's wrong with PVA?
Polyvinyl alcohol is a synthetic polymer that dissolves in water. Some researchers question how completely it breaks down after the drain, while industry groups say it biodegrades under the right conditions. We'd rather skip the debate. Read both sides here.
Does Just 7 create microplastics?
Our film is pullulan, not plastic, and it's designed to dissolve in the wash.† We'll back that up with test data before launch.
What is the packaging made of?
A thin, flat pouch with no plastic window and a peel-and-seal flap to keep moisture out. We're choosing the pouch material now and will name it once it's confirmed.†
Is it safe for septic systems?
We haven't tested that yet, so we're not claiming it. We'll update this answer when we have data.
