Become a Denver Master Composter

Now is your chance to become an expert composter and recycler, and to help curb the culture of waste in Denver. 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 newly acquired 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. Through learning and giving back to the community, Master Compost volunteers also build a community of their own – one of like-minded individuals that are motivated to make positive changes in Denver.

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 pm to 8:30 pm, March through April. Other required sessions include an all-day Friday facility tour in mid-April and two Saturday work days.
  • 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 - Ongoing. You’ll want your boots and gardening gloves for these, May through October.

The Master Composter Training Program is a significant commitment, but a very rewarding experience for those selected to participate. Applications for the 2018 program are accepted now through January 2018. 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 or
