Dustbin Colour Code in India — Waste Segregation Guide

India uses colour-coded dustbins for waste segregation: Green bin — wet/biodegradable waste (food scraps, vegetable peels, leaves). Blue bin — dry/recyclable waste (paper, plastic, glass, metal). Yellow bin — sanitary/household hazardous waste (diapers, sanitary pads, bandages). Red bin — biomedical waste (used syringes, medical items — mainly hospitals). Black bin — e-waste (dead electronics, batteries, CFL bulbs). Orange bin (some municipalities) — non-recyclable residual waste. The system helps ensure different types of waste are treated correctly.

The green dustbin is for wet waste — biodegradable, organic material. Examples: vegetable and fruit peels, cooked food waste, tea and coffee grounds, leftover food, leaves, garden trimmings, egg shells, and flowers. Wet waste is composted to make fertiliser or used in biogas plants. Do NOT put plastic, paper, or non-organic items in the green bin. Wet waste makes up 50–60% of all household garbage in India.

The blue dustbin is for dry/recyclable waste. Examples: newspapers, cardboard, clean plastic bottles and containers, glass bottles and jars, metal cans, tetra packs, clean plastic bags. Do NOT put food-contaminated items in the blue bin (e.g., a greasy pizza box). Dry waste is sent to recycling facilities where it is processed back into usable materials, reducing the need for raw material extraction.

Red dustbins are for biomedical waste — primarily used in hospitals, clinics, and healthcare facilities. They contain: used syringes and needles, medical gloves, blood-soaked bandages, IV tubes, expired medicines. Biomedical waste is treated at authorised facilities by autoclaving (heat sterilisation) or incineration. Improper disposal of biomedical waste is illegal in India under the Biomedical Waste Management Rules 2016 and poses serious infection risks.

Yellow dustbins are for sanitary and household hazardous waste. Examples: used diapers, sanitary napkins, face masks, bandages, cotton balls, used blades. These items cannot be recycled and require separate hygiene-conscious disposal. When mixed with other waste, sanitary items create infection risks for waste collection workers. They are sent to designated disposal or incineration facilities.

E-waste (electronic waste) consists of discarded electrical and electronic equipment. Examples: mobile phones, laptop computers, batteries, chargers, CFL/LED bulbs, printers, cables, circuit boards, refrigerators. In India, e-waste goes into black dustbins or is deposited at authorised e-waste collection centres. E-waste contains toxic substances like lead, mercury, cadmium, and arsenic that pollute soil and groundwater if landfilled. India is the third largest e-waste generator in the world and has specific e-waste management rules.

The Solid Waste Management Rules 2016, issued by the Ministry of Environment, Forest and Climate Change, mandate: Source segregation — households must separate wet (biodegradable) and dry (recyclable) waste before disposal. Colour-coded bins — green for wet waste, blue for dry waste, yellow for domestic hazardous waste. Local urban bodies must set up systems for collection, transport, and processing. Bulk generators (hotels, institutions, markets) must manage their own waste. Composting and biogas are promoted as methods of treating organic waste. The rules aim to reduce landfill waste and promote a circular economy.

Waste segregation is important because: (1) Reduces landfill pressure — recyclables and compostables are diverted from landfills. (2) Enables recycling — clean, segregated dry waste can be effectively recycled. (3) Creates compost — wet waste can be composted to produce organic fertiliser. (4) Generates energy — wet waste in biogas plants produces methane for cooking/electricity. (5) Reduces pollution — hazardous waste separated from general waste prevents toxic contamination of soil and water. (6) Protects waste workers — reduces risk of injury and infection. (7) Economic benefit — recycling creates jobs and conserves natural resources.

Swachh Bharat Mission (Clean India Mission) is a national campaign launched in India on 2 October 2014 (Gandhi Jayanti) by the Government of India. It aims to achieve a clean India by eliminating open defecation, improving solid waste management, and promoting cleanliness in public spaces, roads, and villages. Under Swachh Bharat, colour-coded dustbins were promoted across cities and towns. The mission has two phases: Swachh Bharat (Rural) and Swachh Bharat (Urban). It has significantly improved sanitation infrastructure and awareness about waste management across India.

At home: (1) Keep two bins in the kitchen — one green (for vegetable peels, food waste) and one blue (for clean paper, plastic, glass). (2) Keep a small yellow bag for sanitary waste. (3) Do not mix dry and wet waste. (4) Rinse plastic bottles and glass jars before putting in the blue bin — contamination reduces recyclability. (5) E-waste should be stored separately and taken to an authorised collection point. (6) Batteries, expired medicines, and chemical containers are hazardous — do not put them in regular bins. Contact your municipality for hazardous waste disposal.
