Composting Learning Activities

ILSR developed these Composting Learning Activities under its Neighborhood Soil Rebuilders Composter Training Program to assist community composting sites in training their own community participants. These Learning Activities provide a hands-on complement to our Community Composting 101 Online Certificate Course, which prepares participants to establish and manage composting projects that both engage and serve their communities. These Learning Activities are available for free! Please take a moment to tell us about how you will use these resources, provide feedback, or give input on future resources.
