In the last five years, the city of Toronto has intensified its efforts to reduce the amount of garbage that is taken to landfill sites. [Currently, the Greater Toronto Area (GTA) disposes of its garbage in a dump site in Michigan.] A current analysis of GTA reveals that 36% of waste collected is taken from residences and 64% from businesses and public institutions (hospitals, schools, universities, etc.). A further breakdown is listed below. (Source: Toronto City Summit Alliance.)
