Why our bottles have a metal-free pump
By Jeremy Fain, founder of Restelys. Updated 17 October 2026. 2 sources cited.
A recyclable bottle can become non-recyclable because of a single spring. Design-for-recycling rules explain why.
In a sorting centre, a bottle is identified and routed according to its material. A metal spring hidden in the pump, a label of another material or an unsuitable adhesive can disrupt sorting and lower the quality of the recycled plastic.
The European and French bodies that assess packaging recyclability publish design guidelines: use a single material, avoid metal, choose compatible labels and inks.
We apply them to our bottle: a single plastic, an all-plastic pump, a compatible label. And the EU packaging regulation will require all packaging to be recyclable by 2030.
