Carnegie Mellon University

The Campus Race to Zero Waste (CR2ZW) is a friendly competition and benchmarking tool for colleges and universities to promote waste reduction activities to their campus communities. Over an 8-week period, CMU tracks the weights of how much we throw out, how much food we donate, and how much we recycle. With the goal of increasing our diversion and recycling rates throughout the competition!

The 2025 competition is from February 2 - March 29. Want to be involved? Check out the schedule of events:

During the 8 week competition there will be activities, events, and promotions to encourage the campus community to reduce their race. Check back here or follow the @CMUGreenPractices Instagram page for updates and event details. 

While the competition is just 8 weeks each February and March, you can participate all year by consuming less, reusing more, and choosing to recycle or compost when you can.

CR2ZW offers different levels of reporting for participation in the 8-week competition. CMU will compete in national competitions in the following categories:

  • Diversion Category - the school with the highest waste diversion percentage. Diversion is determined by the percentage of the total weight of recyclables and food organics diverted from total waste generated.
  • Stephen K Gaski Per Capita Classic - the school that collects the largest combined amount of paper, cardboard, and bottles and cans on a per person basis.
  • Food Organics - points are awarded for food waste minimization activities and the amount of food that is diverted from the landfill.
There are also special, one-time reporting categories. CMU often competes in the national Case Study Competition, where schools share their best practices in promoting and improving recycling and waste reduction on campus.
