The compost process takes organic material and mixes it in a bin or a pile where it is turned into a nutrient-rich soil supplement by millions of microbes.
Volunteers with experience in composting will lead the workshop, and low-cost bins will be sold for Riverside County residents.
The free "how-to" workshop will be held at the Hemet Public Library at 300 E. Latham Ave. The workshop is scheduled for 10 a.m. Saturday, Sept. 25.
