Anything which is no longer needed for use and is often thrown away carelessly may be called as waste. Wastes are generated through various sources like domestic, industrial, agricultural, commercial, municipal etc. Wastes from these sources contaminate air, water and land from where they affect the health of the biosphere.

Waste accumulated in environmental media are affecting the biosphere by direct mixing and altering their natural quality and by moving in the biosphere through bio-geo-chemical cycles and food chains operating in nature.
Accumulation of waste in the environmental media affects the environment by following ways -
·         By spoiling the landscape
·         By causing different types of pollution
·         By causing health hazard
·         By damaging terrestrial and aquatic life

The accumulation of waste in the environment causes loss to economy, interrupts bio-geo-chemical cycles, and damages historical monuments. So, it is important to reduce the existing levels of pollutants, checking them at source, fitting of pollution control devices in industries and regular monitoring of environmental quality. All these activities and many more are together called as waste management. In brief, the process of dealing with waste is called as waste management.
