What is in municipal waste

Basics Solid Waste Management Reviewed 23 Oct 2026 2 min read

Municipal solid waste is what households, shops, markets and institutions throw away. Indian city waste typically has a high share of wet organic matter, such as food and garden waste, along with paper, plastics, glass, metals, textiles, and inert material such as dust and debris.

Composition decides treatment. Wet, organic waste suits composting or biomethanation but has low calorific value for burning. Dry recyclables have market value if kept clean. Inerts go to landfill or reuse.

That is why segregation at source, keeping wet, dry and domestic hazardous waste apart from the start, is the foundation of the Solid Waste Management Rules, 2016. Mixed waste is harder to process and more of it ends up in dumps.

Engineers measure generation per head per day, density (which sets vehicle and bin sizes), moisture content and composition, then plan collection, transfer, processing and a sanitary landfill for the remaining rejects.

Key formulas
  • Daily waste = population × per-capita generation
  • Bin or vehicle volume = mass / bulk density
Solved example

Problem. A ward of 20 000 people generates 0.45 kg per head per day at a loose density of 400 kg/m³. Find daily mass and volume.

  1. Mass = 20 000 × 0.45 = 9 000 kg.
  2. Volume = 9 000 / 400 = 22.5 m³.

Answer. 9 tonnes, about 22.5 m³ per day

Quick quiz

1Why segregate at source?

Clean streams are easier to compost, recycle and process.

2Which rules mandate segregation in India?

Solid Waste Management Rules, 2016.

3Why is wet waste poor fuel?

High moisture means low calorific value.
