A portion of the packaging industry is trying to make us believe that the solution to plastic pollution lies in paper and cardboard packaging. That it's enough to gradually replace everything. Is it a noble intention, or a somewhat unscrupulous calculation to try to grab market share? And how do we navigate through all the commercial claims without being deceived?

Discover how and why in this hundred-page dossier by Mr. & Mrs. Recycling, funded by the City of Paris and already qualified by industry peers as the most comprehensive and coherent content on the subject.
