Students pick up their free containers of Stonyfield Farm yogurt at an Oct. 16 event at the School of Natural Resources and Environment. The company gave away 500 cartons bearing the logo of the school’s Center for Sustainable Systems (CSS). The yogurt extravaganza was held to celebrate a successful collaboration between the center and the New Hampshire-based maker of organic yogurt. At Stonyfield Farm’s request, CSS recently completed a life cycle assessment of the company’s product delivery system. (Photo by Paul Jaronski, U-M Photo Services)
