Welcome to Community Composting on ChangeX. Food waste is the largest category of material in municipal landfills, where it creates methane, a powerful greenhouse gas. By composting our food waste we can greatly reduce the amounts of methane produced. In addition, the compost produced can reduce the need for chemical fertilizers and produce higher-yielding crops. We're excited to help you start a local composting program with your community group, church, school or workplace!
