"I had a whole team of four trying to figure out what each plastic was," recalls fourth-year student Kristen Klein, coordinator of the Zero Waste Research Center, a project funded by students via a grant from The Green Initiative Fund (TGIF) ."We separated the plastics out, Nos. 1 through 7," and wrote a "huge report" on the campus's plastics footprint, she says.
