Home Composting

Interested in home composting? Check out our schedule of home composting workshops below. Plus, we've included some of the recommended resources we provide at the workshop for you to check out before hand (or if you cannot make it!). The workshops are brought to you through a collaboration and sponsorship of: the City of Napa, UC Cooperative Extension Napa County Master Gardener Program, County of Napa, and Upper Valley Waste Management Agency. 

Home composting not your thing? Did you know you can put all your food soiled paper products (paper plates, pizza boxes, napkins, paper based to go containers, etc) into your brown compost cart alongside all your food! That includes meat, dairy and bones - items that do not belong in your home compost! For more information check out Napa Recycling's Web page on Home Food Composting
