What category represents the largest portion of municipal solid waste?

The largest portion of municipal solid waste is typically comprised of organic materials, which include food scraps and yard waste. This category often constitutes around 30-40% of total municipal solid waste, depending on the region and its waste management practices. Other significant contributors include paper and cardboard, plastics, and metals, but organic waste generally leads in volume. Reducing organic waste through composting and other methods is a key focus in waste management initiatives.
