Upcycling, a Productive Use of Waste

For a presentation on environment, four of my students put together this phenomenal presentation on upcycling, a more sustainable use of waste products than recycling. I give full credit to Kim Dabin, Han Kyounghee, Lee Seohyun, and Jeong Yerin for such a meaningful and well put together presentation, and I thank them for letting me share it here :)
