Figure below presents the main operations in the water-based production line, the input to the units and the pollution sources. The water-based paints manufacturing steps are similar to those of the solvent-based paints production, except that the raw materials are added to the mixture in different order, and water is used instead of solvent as thinner.
* Work place pollution parameters are ammonia, particulates, and noise.
** Spills or leaks could occur through the whole process, and may contaminate the water if discharged to the sewer.
*** Chemicals empty containers are generated, and considered hazardous. Those hazardous solid waste should be safely disposed into a landfill.
