School Compost Program

Composting at School

If you're researching how to start a school compost program, a wealth of resources are available to get you started. For schools that already have a gardening program in place, adding a compost program will not only complete students' knowledge and experience with nature's cycle of growth and decay, but will also enrich the soil in which the garden grows.

School Friendly Composting Projects

Incorporating a composting program at your school can be a fun, informative way to teach kids as well as faculty the importance of organic matter in soil and the benefit it brings to plant life and our environment as a whole. Billions of microorganisms live in the decaying matter known as humus, which works as a natural fertilizer and soil enhancer. School composting programs are a great way to teach the next generation about the vital role composting plays in providing our soil with regenerative capabilities and our bodies with healthy, good-for-us fruits and vegetables.


Along with traditional composting practices, schools that operate year round may also want to look into vermicomposting which uses red worms. This can even be combined with a gardening project such as growing potatoes in a barrel or box also used to house red worms. Most kids are fascinated by worms, feeding worms and watching the decomposition process and learning about how to use worm casings to enrich the soil. Adding worms to your school compost program offers a number of benefits:

  • Helps to create a sustainable soil structure
  • Makes composting of household type waste easy
  • Provides the possibility of a money making project in the selling of red worms
  • A great source for organic fertilizer

One of the main drawbacks to vermicomposting is that the worms must be fed. If your school closes for holidays or over the summer and you plan a vermicomposting project, arrangements must include plans for feeding at times when school is not in session.
