Segregation of wastes



•    Degradation-The process by which substances are broken down by tiny organisms called decomposers.

•    Biodegradable wastes are those that can be degraded (undergo degradation) by the action of tiny organisms (called decomposers) found in the soil.

•    Non-biodegradable wastes are those that cannot be broken down by decomposers. For example, glass, plastic, and metals.

•    Depending on the type of wastes, two garbage bins - one for biodegradable wastes and other for non-biodegradable wastes should be used.


Green bin               Blue bin

•    Green bins are for biodegradable wastes such as vegetables and fruit peels, spoilt food, tea leaves, egg shells, tissue paper, hair, etc.

•    Blue bins are for recyclable wastes such as glass bottles, polythene bags, plastic wastes, chocolate wrappers, old batteries, etc.
