Mapping Composting Infrastructure and Supporting Legislation

GreenBlue has developed several interactive maps and charts of composting infrastructure and supportive legislation in the United States, available on Tableau Public:

These maps seek to provide insight into basic questions such as where composting facilities are located in the United States and how many accept compostable packaging. Additionally, the maps display where state and local legislation has banned the disposal of food waste to landfills. Legislation that bans food waste from landfills often spurs the expansion of composting infrastructure, since composting is identified as one of several alternative pathways for food waste.

The composting access maps show composting facility locations overlaid on the United States by state and urban populations, with more densely populated areas in darker blue. This information might be used to calculate residential access to composting programs. It can also be used to identify high-population cities that do not currently have sufficient access to composting infrastructure, and are therefore unable to compost food waste or compostable packaging.

Data on what material is accepted at a particular composting facility is drawn from state permit information and individual composting facility websites (such as Missouri Organic Recycling’s website). This information was collected beginning in 2019, and is subject to change as facilities update their policies and practices.
