● Fertiliser factories release effluents and harmful gases as the main waste.

● To control of gaseous pollutants, combustion equipment are used which can be oxidised the pollutants. Air pollutants, such as certain gases and vapour and inflammable compounds are controlled through the use of adsorption equipment.

● Effluents can be controlled by pre-treatment before discharge to municipal treatment systems. Waste water can be treated completely at the factory and either reused or discharged directly.
