Funded by a Campus Sustainability Fund grant, the UW Farm’s vermicomposting facility plays an integral role in creating a sustainable food system. The facility is home to red wiggler worms that feast on vegetable waste from the UW Farm.
The worms eat and process the food waste, breaking it down into “castings.” The castings are harvested and blended with leaves and coffee grounds from the campus compost pile. This nutrient-rich soil amendment is used by UW Farm when planting and growing perennial crops such as fruit trees, flowers, and more!
