As is the case with Mr. Jourdain, who was unaware of what he was writing, industries involved in packaging have already implemented the circular economy model. Results in material recycling are relevant proof thereof. Industries are not getting involved in this process out for ideological reasons but because it often makes sense from an economical point of view. Since we were lucky enough not to be starting from scratch, we offered a tangible approach through illustration for each main material and/or packaging category from: glass to paper, cardboard, food cartons, steel, aluminum, wood, and plastic materials. This also includes the energy consumed by the different materials and the waste produced by all the different activities involved.
