Celebrating 30 years


Green Action Centre promotes composting for all Manitobans by providing information, resources and support. We assist residents interested in starting home composting. We also work with schools, workplaces, and communities to develop programs that address their unique requirements. The benefits and rewards of composting are many, so why not take advantage them?

Green Action Centre offers education through presentations and courses, printed materials, and a toll-free compost information line (1-866-394-8880 or in Winnipeg at 204-925-3776). We also co-oordinate dozens of volunteers through our Master Composter Program, an in-depth composting training and volunteer program that helps reach people in communities all across Manitoba.
