Dispenser for sparkling or still water

What to do with the plastic bottles?
We want to give an answer with our water dispenser, which offers still water and sparkling water. Enclosed there will be nice bottles made of glass, aluminium, but also plastic, but for multiple use. We have thought for a long time whether we should remove the plastic bottle completely from our range. We have now dared this step. This packed with a coherent communication should encourage the guests to switch to reusable bottles, even for sparkling water.
