What is the Master Composter program?

Green Action Centre’s Master Composter Program is an in-depth, hands-on train-the-trainer composting course and volunteer program, allowing participants to provide compost education and outreach to the public.

This program is an excellent opportunity to meet and network with other like-minded people, acquire composting knowledge and to educate others on the value of composting. By becoming a Master Composter, you join a growing community of earth conscious individuals, people just like you!

Once you have finished the course, you are required to complete 30 hours of composting related volunteer activities in the community within a two-year period. Volunteer time is gained by various activities such as helping your family and neighbours start composting, setting up composting programs at a workplace or school, building community compost bins, staffing our display at public events, delivering composting presentations and other activities that promote composting to residents, businesses, schools, and other community groups. Green Action Centre provides numerous volunteer opportunities throughout the year in order to complete your hours. Our volunteer activities involve participating in various highly frequented events such as Gardening Saturday and the Home Expressions Show. As a volunteer you are also encouraged to seek out opportunities yourself.

As a course participant you will learn about composting through various activities, lectures, tours, discussion groups, and videos. Throughout the course, you will gain knowledge on the details of composting including sessions on soil health, compost maturity, biology of the compost pile and vermi-composting activities to name a few. You will also receive a manual that has in-depth composting information.

As a member of the Master Composter Network we will provide you with updates and composting related information by e-mail and through our e-newsletters. Further, special invites for tours and events are offered to Master Composters throughout the year.

Who can apply?

All Manitoban residents, 18 years and older, interested in composting and sharing their knowledge with others can apply. Beginners are welcome!

Expectations and commitment

Master Composter participants are expected to attend all of the course sessions, set-up and operate a backyard compost or a vermicompost at home or at work, and encourage and show others how to do the same. Master Composters must also complete 30 hours of volunteer time to this program in Manitoba within the next two years after completing the course. When working in the community, Master Composters acts as ambassadors for the Green Action Centre.


Green Action Centre strives to provide assistance and guidance to anyone in the community that wants to start composting. We are a registered charity that depends on grants and donations. To help cover our costs, there is a fee of $100 to attend the course. If you cannot afford the fee, please contact us to discuss alternative arrangements. Once the participant has completed their 30 hours of volunteer work, he or she can choose to have $50 refunded or choose to donate it to Green Action Centre for future composting awareness activities.
