Since the beginning of 2018 these white bags for household garbage are mandatory. The bags are for sale in different volumes in the shops and supermarkets in and around Les Masses. The showed 35 L bag costs a fixed price of CHF 1,90. It  -always- makes sense to separate the different kinds of garbage, and now even more. Just below the covered parking of Les Masses one can drop of glass bottles, plastic bottles, paper and cartons, and general household garbage in these white bags. The “Trier? C’est pas sorcier!” means so much as “Sorting? That’s easy peasy!”
