Yard Waste Compositing

Yard Compost

Yard Waste comes from the maintenance of the SLU grounds, whether its tree branches, bushes, flowers, or other natural plants around SLU's campus.

Yard waste that was previously hauled away is now composted on campus by the Grounds department. All yard waste that cannot be composted on-site (i.e. tree stumps) is composted at the landfill site. However, the majority of the debris generated from the grounds operation is kept on site, composted, and re-used throughout campus areas. This composting helps to generate needed nutrients for plant life in the flower beds around campus and keeps it out of the landfill. For additional information visit Buildings & Grounds

Food Compositing

Composting ToteCompost Sign

These totes are being used for pre-consumer composting, and are each labeled with this yellow sign

Collection of food waste is sorted at various dining locations around campus as part of the pre-consumer composting process.  Pre-consumer, also known as back-of-house composting, includes any food or paper organic waste that is created or food scraps discarded during the food production process. This means that consumers might not readily notice the compost collection process occurring behind the scene.

Tips for the SLU community:

  • These containers are generally used by food service workers only.
  • Be on the look-out for these totes on campus behind buildings. Do not put single-stream recycling items in these containers. 
  • Only organics can be put in these containers: food waste (banana peel, apple core, egg shells), paper products (plates, paper towels, napkins, paper bags), and BPI-certified plastics.
  • Do not put: plastic water bottles, metal cans or glass bottles in these containers. Contamination over three percent will force the whole container to be rejected.

All food at Fresh Gatherings Cafe is served on fully compostable plates, cups, bowls, etc. Beverage cups are compostable (both hot and cold). The garden program utilizes seven compost tumblers, one large industrial sized tumbler, an Earth Tub, and a vermiculture system for management of both pre- and post-consumer food waste.

Higher purpose. Greater good.
