Si diffonde nei negozi e nei centri commerciali la tendenza a obbligare la clientela a usare sacchi per la spesa riutilizzabili. Migros dal primo novembre ha fatto sparire i piccoli sacchetti bianchi gratuiti alla cassa. Chi ne vuole uno lo paga 5 centesimi. L’obbiettivo è di ridurre l’inquinamento.
Milioni di questi sacchetti finiscono negli inceneritori ma molti restano per strada, nei prati, nei boschi.
Gli svizzeri ne utilizzavano 130 all’anno a testa: significa circa un miliardo di pezzi.
I primi riscontri del grande distributore sono positivi: il consumo è calato di quattro quinti nonostante il prezzo molto contenuto dei sacchetti sostitutivi.
Anche Coop si appresta a metterli al bando. Nelle regioni dove la misura è stata introdotta vi è stata una diminuzione dell’80%. Per ora Denner e altri negozi della grande distribuzione li mantiene ma nel corso del prossimo anno spariranno definitivamente.
