Composting is a process that turns organic waste (usually food scraps) into nutrient-rich soil.

A Cross-Campus Effort

Campus Dining collects the food scraps that FSA Volunteers load into the composter and track the progress. After 3 weeks, campus operations and maintenance unloads the compost to be cured and distributed in the landscaping and flower beds throughout campus.

What to Compost

  • coffee grounds
  • coffee filters
  • tea bags
  • fruit and vegetable waste
  • spices
  • egg shells


  • Reduces Carbon Footprint
    • Stony Brook uses an aerobic composter. Less waste gets carted by diesel trucks to landfills and less methane gas is released into the atmosphere.
  • Recycles Local Waste
    • In order to create compost, we need nitrogen, carbon, air, and time. Food waste creates nitrogen. Our carbon element is locally sourced sawdust, the waste product of a cabinet manufacturer, which binds the matter into a product good for the environment.


  • Total waste collected to date: 235,000 pounds
  • Total compost output: 100,000 pounds
