Segregation at Source: A Practical Guide for Bulk Waste Generators

Segregation at source is the foundation of every effective solid waste system — something I have seen first-hand while preparing municipal master plans. If waste is mixed at the point of generation, composting, recycling and safe disposal all become harder and more expensive. The Solid Waste Management Rules place clear duties on generators, and additional duties on bulk waste generators.

Three streams, at minimum

• Wet (biodegradable): kitchen and food waste, garden waste.
• Dry (non-biodegradable): paper, plastic, metal, glass, packaging.
• Domestic hazardous: used batteries, paint cans, expired medicines, CFL bulbs; sanitary waste wrapped securely.

Who is a bulk waste generator?

Bulk generators typically include large housing societies, commercial establishments, hotels, hospitals, campuses and offices above area or daily-waste thresholds set by the rules and local bye-laws. They usually must segregate and process wet waste on-site as far as possible, or hand it to authorised processors.

Five steps to make segregation work

1. Baseline: weigh and characterise your waste for a week.
2. Infrastructure: colour-coded bins at every generation point and a secure central collection area.
3. People: train housekeeping staff first, then residents or employees; appoint block champions.
4. Processing: size an on-site composter or organic waste converter, and tie up with authorised recyclers for dry waste.
5. Monitoring: check segregation quality weekly and share results.
