Solving global problems isn't on the to-do list for most teenagers.
But this group of five teen girls from Delhi, India, is far from average. The team took on the challenge of inventing a way to dispose of electronic waste in an eco-friendly way.
"E-waste is usually disposed of as regular trash, which causes all types of environment pollution and great health hazards," the team told "GMA" during a group presentation.
Discarded tech equipment -- phones, computers, TVs -- contains substances that cause environmental damage and health risks, especially if treated inadequately, according to the 2017 Global E-waste Monitor, a report produced in part by United Nations University.
Calling themselves Team Cantavits, the girls worked together to create a mobile app called Eedo that allows for full communication between e-waste producers and authorized recyclers. This summer they won the senior division at the 2018 Technovation World Pitch Summit in San Jose, California.
They were one of 12 team finalists at the competition that were collectively awarded more than $50,000 in scholarships to continue pursuing tech entrepreneurship, and to bring their apps to market. Iridescent, a nonprofit working to empower underrepresented youth around the world, founded the Technovation challenge in 2010.
A spokesperson for Iridescent said Team Cantavits is already meeting with e-waste experts in India to get licensed recyclers to join the app.
