Some 110 stands will present products or services at the 2015 Feria del Ambiente that opens Wednesday at the Antique Aduana on Calle 23. The event runs through Friday from 8:30 a.m. to 7 p.m.
In addition there are discussions each day on topics as critical as the handling of municipal trash and how to reduce the carbon footprint of public transport, said an announcement.
Organizers expect 25,000 visitors. This is the 11th annual edition. Many major corporations will be presenting themselves as environmentally progressive.
