With music by Yo-Yo Ma, a 15 ft. by 18 ft. cake, talking trees, and the Widener steps all lit up, it's no secret that fair Harvard is going all out for tonight's festivities. But did you know that it's green not crimson, that's in at Harvard's 375th?

Nothing is expected to be wasted during tonight's festivities, thanks to careful planning by the Harvard University Dining Service, Recycling and Waste Services, and the Harvard Office of Sustainability.

"The police want a zero crime rate, firefighters want zero fires, and we want zero waste," said Rob M. Gogan, Jr., Harvard's recycling and waste manager.

Not only will desserts be served in recyclable dishware, all the leftovers from the night will be composted, according to Gogan. Keep an eye out for the 120 recycling stations located at major vantage points as well as at all entrances to the yard: green-lids are for composting leftovers and dishes and blue-lids will be for recycling paper, glass, plastic, and cans.
