Waste segregation at source can reduce up to 250 tonnes of dump from entering into landfills.
Waste segregation can be defined as the process of identifying, classifying,dividing and sorting of garbage and waste products in an effort to reduce, reuse and recycle materials.
In order to segregate waste appropriately, it is important to correctly identify the type waste that is generated. For the purposes of waste segregation at source, waste is identified and classified into the following categories depending on their biological, physical and chemical properties:
- Dry Waste – Refers to all items that are not considered wet/soiled items. This includes both recyclable and non-recyclable materials. Dry waste includes items such as bottles, cans, clothing, plastic, wood, glass, metals and paper.
- Wet Waste – Refers to all items that are organic like food items, soiled food wrappers, hygiene products, yard waste, tissues and paper towels, as well as any other soiled item that would contaminate the recyclables.
- Sanitary Waste – Refers to all liquid or solid waste originating solely from humans and human activities. (Can also include items from medical waste)
- Hazardous Household Waste – Refers to all household products that contain corrosive, toxic, ignitable, or reactive ingredients, other than used oil.
- E-Waste – Refers to all kinds of electronic waste.
- Hazardous Waste – Refers to all items, products and by-products that contain corrosive, toxic, ignitable or reactive ingredients.
- Inert Waste – Refers to waste items that are neither chemically or biologically reactive nor decompose easily.
Significance of Waste Segregation
Waste segregation is critical because of the fact that certain types of wastes can be hazardous and can contaminate the environment if not managed correctly. (Some of these types of waste may also have the potential to cause disease or get into water supplies or contaminate the land with different types of leachates.)
When waste is unsegregated, it may get contaminated with different types of waste being stored together. Such waste cannot be treated or managed and most of the time end up being dumped into local dump yards or landfills. With waste segregation, management of different types of wastes becomes possible. This directly results in reduced amounts of waste being dumped at dump yards or landfills.
Waste Segregation is always step one for all types of waste management solutions that may be implemented either on individual level or community level.
Color Codes for Bins
For ease of waste segregation, the disposal bins are color coded.
| Type of Waste | Color of Bin |
|---|---|
| Wet Waste | Green |
| Dry Waste | Blue |
| Sanitary Waste | Red |
| E-Waste | Black or Grey |
| Hazardous Waste | Black |
Placement of Bins for Waste Segregation at Source
The best way to segregate waste is to segregate it at source. To enable this, it is always recommended to place the right type of bin in the respective area.
| Areas | Wet Waste | Dry Waste | Sanitary Waste | E-Waste | Hazardous Waste |

| Bedroom |  |  |  | ||
| Kitchen |  | | | ||
| Toilets | | | | ||
| Living Room | |  | |||

Government Directives on Waste Segregation
Several government departments, pollution control boards and the National Green Tribunal have made Waste Segregation at Source Mandatory across the country in efforts to promote decentralized waste management.
