Food Scraps Composting

Food scraps come from many sources. Composting food scraps is a better use of organic resources than landfilling, and it can decrease refuse collection costs over the long term. For more information on food scrap composting, see the Organics Food Scraps Management FAQ page. Contact your local enforcement agency for guidance on any local permit requirements prior to beginning a compost project.
