ditives to film to accelerate biodegrad-ability.
By the end of the conference, we
had co-developed a road map toward
a more sustainable squeeze pack that
involved taking small steps. We set the
goal for Justin’s to convert one-third
of our film to a sustainable film structure by Earth Day 2011.
together, as of May 2011, we have four new film structures that did not
exist before the summit. Two are made from 33 percent renewable resources and two are fully compostable. These are:
• A 33 percent renewable film that uses corn-derived PLA in the
outer layer via Nature Works Technology converted by CP. This one
is the most affordable, but it’s made from GMO corn.
In continuation of our sustainability promise, over the last year, Justin’s
has been sending out periodic
e-newsletters to all attendees updating
them about our progress and sharing
as much information as possible. We
have also created a website where
people can follow the journey and
learn more about it ( www.justinsnut-
butter.com/sustainableSqueezePack-
J ourney.php). Some of the
presentations from the event are
posted here as well.
• A 33 percent renewable film that incorporates cellophane from eucalyptus trees in the outer layer using Innovia technology converted
by CP. This structure is expensive and may be too brittle for our uses,
which require it to be exposed to a wide range of temperatures.

Additionally, a group of graduate
students from Boulder Digital Works,
an affiliate of the University of Colorado–Boulder, created a new concept in consumer “inactivism” via a
website called The Least You Can
Do.org, which helps drive support
and awareness for the cause through
several easy yet powerful steps. For
more on this, see “The Least You Can
Do; An Inactive Approach to Consumer Activism” on page 26.

The Long and Winding Road
Just six months after the Sustain-
able Squeeze Pack Summit, Earth Day
2011 came and went… and we had
still not achieved a 33 percent renew-
able squeeze pack. This was for two
reasons. First, our new squeeze pack
machine had still not arrived. Since
we are changing the shape of the
squeeze pack, we would not be able
to implement a new film on our old
machines.
Secondly, we are still testing films
and need to work out a few kinks before we can launch the new packaging. We have, however, made amazing
progress toward finding a solution. Al-
