RecycleSmart offers the following types of free workshops and services: 

Home Composting for Busy People: Lecture-style workshop (virtual and in person). Covers the basics of backyard composting (hot/cold composting), Vermicomposting, mulching and grasscycling, with time for Q&A and troubleshooting.

Vermicompost & Bin Building: Learn to compost with worms! This is a hands-on workshop. You will assemble your bin, take it home with your worms and knowledge, and start composting right away! All supplies and worms included. It is very important to provide cancellation notice 48-hours prior to a worm workshop. These are living creatures and no-shows create challenges and unecessary cost. 

Compost in the Classroom: The Gardens at Heather Farm​ in Walnut Creek offers composting classes at no cost to any school within the RecycleSmart service area. Click here for information and scheduling. 

Additional Services: RecycleSmart composting instructors can table at events and Farmers Markets, come into your neighborhood (5+ homes), schools, community groups, presentations and demonstrations, upon request, at no cost. Call RecycleSmart for more information or to schedule at 925-906-1801.
