Thessaloniki is in Macedonia in Northern Greece. Located on the coast, it is the second largest city in Greece and boasts a busy commercial port. The temperature in the Summer reaches 40° and attracts many overseas tourists who stay at seaside towns along the coast of Thessaloniki, as well as day trippers from Halkidiki, a resort near Thessaloniki. With its cosmopolitan nature, it also draws business people who hold meetings at its many venues. The HELEXPO Centre holds exhibitions and conferences all year round, which encourages more visitors to the city and adds to its waste production. Tim Byrne, specialist in waste collection in Mediterranean countries, reports.
