Alexandre Michaud is a student of professor of design Sylvain Allard, who keeps a nice blog called Packaging UQAM that often features his students' solutions to design issues:

"The simplistic thinking in eco-packaging would
suggest that all it needs is to take a recycled Kraft cardboard and the
job is done. Unfortunately, it's much more complicated than that and
demonizing plastic over paper is another non-sense. In fact, there are
as many solutions as there are different packages and each one should
be developed taking into account production methods, materials,
transportation and many other factors that ultimately determine the
true lifecycle of the product.

However, the reduction approach
remains the most easily measurable element of ecodesign. Indeed, by
reducing the amount of material, it reduces the weight of the
interventions in upstream and downstream production because there will
be less material to produce, to collect and to recycle.

I asked my students to develop a package that consisted of grouping two
products in an approach inspired by the 3Rs, Alexandre Michaud has
developed this double pocket for a gel and body moisturizer for man.
The word Wer means Man in Old English. "
