The Mercabarna-flor Wholesale Businesses Association (AEM) collaborated once again this year in International Day of Older Persons, held on 1 October. The collaboration consisted of donating 2,000 carnations which were distributed to passing senior citizens during a solidarity march through the centre of Barcelona. More than 150 people including volunteers, partners and collaborators of Amics de la Gent Gran (Friends of Senior Citizens) took part.
