Master Composter Program

Master Composter courses are a unique opportunity to gain a more in-depth understanding of the composting process and provide insight on sharing this knowledge and passion with others. For the time being, our courses have gone virtual so that we can continue to train composting ambassadors in our region while keeping everyone safe and healthy.

The course covers the following:

  • Traditional composting
  • Building, maintaining, and troubleshooting a compost pile
  • Vermicomposting
  • Bokashi fermentation
  • The microbiology of composting
  • Macrodecomposers in your compost pile
  • Environmental impacts
  • Much more!
