It aims to produce reusable shopping bags, food packaging and e commerce enveloppes.  Circular Challenge enabled them "to raise our profile and visibility, and above all to reach a vast network of potential users that Citeo was able to put us in touch with" according to Arnaud Jouvance, development director for France.
