Master Composting & Recycling Education

Are you passionate about reducing waste and ready to be more active in your community? Gain expertise in food waste prevention, composting and recycling, resource conservation and soil building -- then teach others!

Seattle Tilth manages three composting and recycling education programs that provide in-depth training to prepare volunteers to go out into their communities to help their friends, neighbors and the public conserve natural resources and make good use of waste that would otherwise end up in the landfill.

Following the training, volunteers commit to providing outreach to share what they learn, such as tabling at farmers markets and community festivals, hosting a workshop with friends and neighbors, or installing a compost bin or drip irrigation at a community garden.

Attend an upcoming volunteer orientation to learn more about Seattle Tilth's composting and recycling volunteer programs in Seattle and King County.
