Dyes are substance or chemicals which impart color to a material. The manufacturing process is complex and at times hazardous. The techniques differ in manufacturing of various dyes. After the invention of synthetic coloring agents many product types have been manufactured for different applications.
The process requires synthesizing, filtration, drying and blending with other products and additives. The final product is then ready for use. After synthesis the product is separated using distillation precipitation and then crystallization. After this fishing operations are carried out.
The manufacture releases air pollutants some of them are NO2, SO2, volatile organic compounds and hydrogen chloride. Solid wastage effluents and sludge are also of major concern. Various treatment methodologies are applied to destroy or lessen the presence of toxic elements released during production.
Pollution prevention and control is a must during the process of production. The amount of toxic wastes has to be minimized. Use of alternative dyestuff is recommended instead of azo dyes for textile manufacturers. It is wise to reuse intermediates or by products than throw them. Minimize spillage by using automated filling plants similarly toxic packing material can be sent to the supplier for reuse. Reduce the generation of waste water and discover uses for rejected lots if possible. Replace highly harmful raw materials with bio degradable ones.
Land use for the plant and the neighboring lands should be protected from toxic pollutants and wastes. On instance of accidental release or spillage of toxic substances a prevention and protection plan should be ready. Quality design inputs and maintenance should be implemented in order to minimize toxic emissions. Careful monitoring and control process along with frequent analysis and reporting is a must.

The complicated process of dye manufacturing in India is highly advanced. The chemical industry produces many dyestuffs and intermediates to facilitate the production locally. The products are slod with India as well as exported to many other countries in the world.
