Columbia University Facilities has partnered with Undergraduate Housing, Environmental Health & Safety, Environmental Stewardship, and Eco-Reps to help you. Twice a year, as part of our Clean & Go Green program, we will make dumpsters available across campus, at no cost to you, for the disposal of large unwanted items. You can also shred paper as well. Best of all, Facilities will properly separate your items for donation and recycle them. That way, when you clean, you "go green!"
