Housing more than 700 companies and operating 24 hours a day, Mercabarna is the Mediterranean’s biggest food hub. It guarantees the supply of fresh food to over 10 million consumers. The companies at Mercabarna specialise in the distribution, preparation, import and export of fresh and frozen products, such as fruit, vegetables, fish and meat as well as processed and semi-processed food. Our guided walking tour led us to the Central Fruit and Vegetable Market, the Food Bank warehouse which serves as a collection and distribution centre for the excess fresh food donated by the companies, and the “Green Point” where Marcabarna’s waste is collected and separated.
