Proposal for SPB, spanish container manufacturer and provider of Mercadona. Our idea consists in a Re-chargable spray with concentrated additive cleaner pill and water instead of buying new Cleaners containers when it run out. This idea allow us to create a more comfortable product that respects the earth with a closed lifecycle. Finalist in the "Envase y embalaje" contest from Cluster de innovación en Envases y Embalajes.
