Tornano i “vuoti a rendere” in Gran Bretagna, per lattine e bottiglie di bibite, con un obiettivo specifico: favorirne lo smaltimento controllato in funzione anti-inquinamento. Il provvedimento, annunciato dal ministro per l'Ambiente Michael Gove, prevede il pagamento di depositi da 22 pence, ossia circa 30 centesimi di franco, per ciascuna bottiglia di plastica, di vetro o lattina d'alluminio.
Il denaro potrà essere poi recuperato lasciando i "resti" in apposite macchine-cassonetto dotate di distributore automatico di spiccioli. La misura, mutuata sul modello della Germania, mira a promuovere una gestione ecologica dei rifiuti riciclabili. Ma più d’ogni altra cosa, vuol limitare la dilagante dispersione della plastica che minaccia soprattutto i mari. È una scelta “vitale per salvare la natura”, ha rilevato Gove.
L'apparecchio colombiano che ricicla lattine e bottiglie in cambio di ticket della metro
Altre nazioni hanno ideato soluzioni simili: per esempio a Medellin, in Colombia, chi ricicla bottiglie e lattine riceve in cambio biglietti per la metropolitana.
