The annual event, which started in 2005, puts together leading experts from environment-related industries to promote eco-friendly products and services.
The exhibition presents a variety of activity-centered booths where children can engage in crafting eco-friendly sculptures, generating electricity by pedaling bicycles and playing drums made out of recycled materials.
Admission is free. The exhibition runs through Saturday.
