make things” thinking about the materia
our products are designed and assembled,
of use with our customers.
No matter how good your products are, the
when their first useful life comes to an end
product life cycles Cradle to Cradle asks us
commonplace approach of “take, make &
prompted us to act.
During the early stages of the design of Ara w
relationship with one of Cradle to Cradle’s aut
industrial chemist Micheal Braungart. Through
development we have been working with EPEA
organisation based in Hamburg.
We’ve always very carefully considered the mat
in our products but our aim in working with E
that what we’re using is truly safe, for h
environment alike, and successful in technica
This means looking in much more detail a
ingredient in the materials we use; to determ
this aim and need to be substituted or remove
