Free Virtual Worm Composting Workshop

A FREE virtual worm composting workshop will be offered by the Contra Costa County Department of Conservation and Development on Saturday, December 6, 2025, from 10:00 AM to 12:00 PM.

You’ll learn how to create your own worm compost. Vermicomposting (“vermi” is Latin for “worm”) is the process of using worms to break down organic food waste into nutrient-rich soil. The worms consume decaying food scraps and produce vermicompost, an excellent soil supplement. This process also produces a liquid fertilizer and worm castings (a fancy name for worm poop!). Worm castings are one of the best types of compost: solid, odor-free, and full of nutrients. You can collect these castings periodically and use them as a soil additive, conditioner, or even light mulch.

The workshop will be led by Todd Sutton, an environmental expert with over 30 years of experience. Todd has appeared on national television, including the Discovery and History channels, and has educated thousands of people on waste prevention, recycling, and composting.

Did you know that Californians generate an average of nearly 2,000 pounds of waste per person each year, amounting to more than 76 million tons statewide? Nearly 40% of this waste is organic material, like food scraps, that can be composted with worms. Vermicomposting is a space-efficient way to recycle kitchen scraps, reduce landfill waste, and create nutrient-rich worm castings that enhance soil health and plant growth.

All Contra Costa County residents are encouraged to participate, and others are welcome to join as well. This live online event will be hosted via Zoom, with the link provided upon registration. Join us to gain valuable composting skills that benefit both your garden and the environment. For more information on composting and recycling, visit http://www.cccrecycle.org/.
