Explanation

Municipal solid waste bundles together household waste, sanitation residue, street sweepings, and construction-linked material and debris.

Statement 1 holds because kitchen and domestic discards form the bulk of city waste.

Statement 2 holds because sanitation residue from drains and toilets enters the municipal stream.

Statement 3 holds because litter and sweepings from streets are collected by local bodies.

Statement 4 holds because building rubble and debris are handled as part of municipal waste.

Segregating this mix into wet and dry fractions is the first step in its management.
