The Riverside County Department of Waste Resources offers a variety of FREE Composting, Vermicomposting and Green Cleaning classes in several locations throughout the County.

Backyard Composting

Saturday, March 2, 2019 at 12 p.m. at the Corona Public Library

Attend a FREE class and get information about how to compost yard, fruit, and vegetable trimmings at home.  This class provides an introduction to composting.  Residents will get an overview of the composting process, how different methods of composting work, and the benefits of each.  Residents learn what materials can be used for composting so that it is successful and productive.  

After the class, the Department makes low-cost compost bins available to Riverside County residents. 


Saturday, March 2, 2019 at 1:30 p.m. at the Corona Public Library

This FREE class teaches residents about vermicomposting, a composting method where worms convert food scraps into two of the best amendments on earth: worm castings, a fancy name for worm poop; and worm tea, a liquid fertilizer derived from either castings or the leachate collected from a worm bin. Residents learn how to care for the worms, make bedding, and harvest a worm bin. 

Following the Vermicomposting class, there is a hands-on workshop where attendees make their own worm bins to take home.  Participants are taught how to harvest worms and receive enough worms to start their bin.  Supplies to build a worm bin are necessary for this workshop. You can purchase a kit at the workshop for $26 or bring your own materials.

All classes are FREE and registration is not required. Class times and locations are subject to change. For more information, please call (951) 486-3200 or visit
