Gault Elementary in Santa Cruz, CA has a compost system that includes vermicomposting and bin composting. The vermicompost is used for composting food scraps from nutrition education tasting activities in the garden and food scraps from the three kindergarten classrooms’ snack scraps. There are two composting bins and a tumbler, which are used to compost the school lunch waste and cafeteria waste three days per week. Children collect buckets from lunch area and bring the food scraps in a wagon to the garden where they dump the bucket into the compost bin and add an equal amount of a carbon source (dry leaves or straw) and a scoop of dirt to introduce microbes. Lunch supervisors monitor the buckets during lunch time. The finished compost is then applied to the school garden at Gualt Elementary.
