Chemical Purchasing

The chemicals that should be monitored under the input focus area are:

• Formulations: Used directly in the production processes and applied on the substrate. (For example, dyes, pigments, washing agents, softeners, finishing agents, tanning agents, fat liquoring agents, adhesives, etc.)
• Commodity chemicals: Used as aids in production processes or in effluent treatment operations and expected to be washed out and contaminate the wastewater. (For example, acetic acid, Glauber's salt, hydrogen peroxide, soda ash, etc.)
• Solvents: Chemicals used in production processes to dissolve, disperse, dilute, extract, carry, or adjust the viscosity of chemical formulations. Solvents may also function as reaction media, catalysts, or cleaning agents for production equipment. They are used across a wide range of manufacturing operations, including, but not limited to, coating and textile printing. Examples include acetone, methanol, toluene, and perchloroethylene.
• Other chemicals: Other chemicals such as utility, cleaning, pest control, paints, samples, laboratory, etc.
