Segregation at Source and the 2016 Waste Rules

Why separating waste at home is the foundation of good waste management, and what India's Solid Waste Management Rules, 2016 require.

Mixed waste is hard to process. When food scraps mix with plastic and paper, recyclables get dirty and compost gets contaminated.

Segregation at source

Segregation at source means separating waste at home or at the business:

Wet: food and garden waste, for composting or biogas.
Dry: plastic, paper, metal, glass, for recycling.
Domestic hazardous: batteries, medicines, paints.
Sanitary waste, wrapped separately.

The 2016 rules

India’s Solid Waste Management Rules, 2016 require:

Households to segregate waste into at least three streams.
Local bodies to collect segregated waste and set up processing.
Bulk generators, such as large housing societies, hotels and malls, to process wet waste on-site where possible.
User fees for waste services.
Integration of waste pickers.
Fines for littering and burning waste.

Why segregation matters economically

Recyclables keep their value when clean.
Composting and biogas work better with clean wet waste.
Less waste goes to landfills, saving land and money.

Challenges

Habits: people are used to mixing waste.
Collection: if collectors mix segregated waste in the truck, people lose motivation.
Processing capacity must exist.
Enforcement of fines.

Home composting

Many households and societies compost wet waste on-site, reducing collection needs.

The two bins

A housing society gives each flat a green bin for wet waste and a blue bin for dry. Wet waste goes to a composter in the society; dry waste is sold to a recycler. The society sends far less to the landfill.

Thinking segregation is pointless because it all gets mixed later

Where collection and processing are organised, segregation keeps materials valuable and reduces landfill waste.

Key takeaways

Segregation at source separates wet, dry and hazardous waste.
The 2016 rules require household segregation, user fees and bulk generator processing.
Clean streams keep recyclables and compost valuable.
Collection and processing capacity must support segregation.
