Material A[]
Grass. It is the leftover grass from a mowed lawn.
Disposal: Grass clippings cannot be disposed of in the City of Toronto. Collections will not accept any yard waste containing grass clippings. [1]
Best Alternative[]
Grass clippings should be left on the lawn, as they are largely comprised of water and decompose rather quickly. This helps your lawn to grow healthy as it releases nitrogen back into the soil and new grass. [2]
