Students from the ArtCenter College of Design in Pasadena will compete with other students from LA County in Junk Battle from 2 to 6:30 p.m. on Friday at the LA Kretz Innovation Campus, 525 S. Hewitt St., Los Angeles.

The students will compete to create amazing things from a big pile of trash. Previews of the work have revealed a hat made out of broken bottles and scraps of paper, a backpack fashioned from the upholstery of old chairs, and repurposed concrete turned community garden structures.

Students and professors from Pasadena City College, USC, Cal Arts and LA Trade Technical College will participate.

The students will use trash from their own schools to complete their projects.

“Imagine TED meets architecture-and-design studio meets hackathon meets innovation black belts, and you’ve just imagined what Junk Battle can be,” said Creative Director John Bielenberg.

The event, moderated by Brandt Williams, features Marcus Eriksen, adventurer, environmentalist and founder of  5 Gyres which battles the global health crisis caused by plastic pollution. Other speakers include: Heather Repenning, vice president of the Los Angeles Board of Public Works; Bonny Bentzin who serves as the deputy chief sustainability officer at UCLA; and John Bielenberg, life-long design insurgent and founder of the Think Wrong Institute, which provides software and training for problem solving.

Judges include: adventurer and activist David de Rothschild; CEO of COMMON; former pro drummer and Zen priest Mark Eckhardt; entrepreneur and member of Apple’s original Mac team Kathy Schlein; and Ken Bielengerg, a computer animation pioneer who brought “Shrek” to the big screen.
