Become a Denver Master Composter

The Denver Master Composter Training Program offers Denver residents a unique opportunity to both learn about composting and recycling topics, and to give back to the community through 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 solid waste management. In return, Master Composters then share this newly acquired knowledge with the greater Denver community by teaching free “Learn to Compost” workshops and participating in outreach events at community gardens, schools and local farmers’ markets.

Here’s a little more about how the program works and the level of commitment required:

  • Instruction: Master Composters receive 40 hours of instruction in the science behind the composting process, resource conservation, compost bin construction, vermicomposting, recycling, solid waste management, and community outreach.
  • Service: In exchange for this training, Master Composters are required to complete 40 hours of self-paced outreach between May and October. Please note, outreach opportunities often fall on evenings and weekends, and participants need to provide their own transportation.
  • Dedication, not experience: Master Composters do not need to be experienced composters or gardeners to participate, but participants must be able to commit the time necessary to attend the classes, tours, demonstration sessions, and also complete the 40 hours of outreach.
  • Cost: A $40 fee is required to help cover the cost of program materials. However, an inability to pay the fee should not deter qualified candidates! Under certain circumstances, the fee can be waived.
  • Schedule: Training classes are held on Monday evenings from late February through mid-April. There is also a Friday tour in April as well as two Saturday work days requirements. Outreach hours are self-paced, but must be completed between May and October.
  • Enrollment: Each year, approximately 35 enthusiastic and committed participants are selected for this program.
