We want to demonstrate that it is possible to bring production back locally, we have the skills and resources here, we have to relearn how to use them. 
If there is a need to create new solutions, 
we will do so.

What customers say
"Serie K has allowed us to offer our customers, from our beginning, a reusable delivery package, for zero waste logistics. The team was super agile and responsive to offer us a solution that met our needs. And our customers love our package :-)" Clother

We worked together


"We are delighted to have collaborated with Serie K, who offered us a creative and environmentally friendly solution for upcycling our construction site banners. Their know-how in recycling our old construction banners into laptop cases demonstrates a real commitment to sustainability and the reuse of materials. By transforming these banners into something useful and practical, they help reduce waste and conserve natural resources. Congratulations to Serie K for their innovation and their positive contribution to our environment.​"

Vision du Réel

"It’s a real pleasure to collaborate with Serie K to upgrade our festival banners. Reviving elements of our infrastructure is essential for us with a view to sustainable development. The rendering of the deckchairs was magnificent, the quality was there and the collaboration was warm."

Did We Do

"We are happy to be able to collaborate with Serie K, a local partner responsible for the revaluation of advertising products."

Association la Guinguette

"Serie K allowed us to recycle our promotional banners which were destined for the dumpster... After going through the Serie K mill, we received magnificent objects which we can now sell for the benefit of our little festival."
