Apply Today to Become a Denver Master Composter

The Denver Master Composter Training Program offers Denver residents a unique opportunity to learn about composting and recycling topics, and to give back to the community by sharing this information with others. Through classroom seminars and hands-on experiences, Master Composter participants study a broad range of topics, including the science behind the composting process, compost pile construction, resource conservation, and recycling. In return, Master Composters share this knowledge with the community by teaching free “Learn to Compost” workshops and by participating in outreach events at community gardens, schools and local farmers’ markets. 

No prior composting experience is required for this program, but all program participants must be able to commit to the following:

In-Depth Compost Education (40 hours). Classroom sessions are held on Monday evenings from 6 p.m. to 8:30 p.m., March through April. Additional sessions are held on weekends in late April. An all-day Friday field trip in mid-April is also required.

Community Outreach (40 hours). Volunteer give-back hours are self-paced, but include some weeknights and weekends from May through October.

Hands-on Work Days (Hours included in Education and Outreach requirements, outlined above). You’ll want your boots and gardening gloves for these! 

The Master Composter Training Program is a substantial commitment, but a very rewarding experience for those selected to participate. Applications for the 2019 program are accepted now through January 2019. To view more detailed program information and application details, visit or call 303-292-9900.
The Denver Master Composter Program is offered through the partnership of Denver Recycles and Denver Urban Gardens. Learn more at
