Pesticide Sector comprises many processing units which adopt different technologies, equipments, unit process and unit operations for manufacturing various products. The manufacturing processes lead to generation of a wide spectrum of air pollutants, mainly inorganic hazardous air pollutants. Some of these pollutants are toxic, responsible for damage of materials and creation of malodour. Besides these hazardous air pollutants, volatile organic compounds (VOCs) mainly solvents are generated as fugitive emissions. In order to reduce the air pollutants emissions to an acceptable level, it is necessary to adopt a comprehensive approach considering possible thermal destruction, recovery of chemicals, good engineering practices and end-of-pipe technology with due regard to techno-economical feasibility within the framework of National Environment Policy (NEP), 2006. Within this backdrop, the Central Pollution Control took up a study to develop National Emission Standards for the Pesticides Manufacturing Industry.
