The economics for this project are presented in comparison to the previous operating situation with essentially no waste treatment, and to estimated costs if a conventional precipitation and neutralization waste treatment system had been installed without modifying the manufacturing process itself.
The approach taken for this project gave a major reduction in pollutants, including sludge, at a slight profit, whereas the isolated installation of a waste treatment system would have resulted in a major cost to the company.
Several changes were made in the plant operation simultaneously with the installation of the pollution abatement system resulting in a total of 2007 USD 130,000 annual savings cost in the drawing operation. The credit of 2007 USD 39,000 annually for increased die life taken for this project is an estimate by the Volco staff.14
