Motorola-Ed Bluestein has installed a sulfuric acid reprocessor to capture and reuse sulfuric acid. The reprocessor captures the sulfuric acid waste stream from our semiconductor fabs (80% by weight), concentrates the stream through a water removal process (to 95% by weight), removes organic and metallic contaminants from the acid, and eventually produces wafer-grade acid for use back in the process.
This Reprocessor was specifically designed for semiconductor manufacturing and is unlike any Reprocessor previously made It is capable of delivering sulfuric acid back to the production line at purity levels never before realized while simultaneously preventing a large volume of hazardous waste from being generated.
The system has already reduced the amount of sulfuric acid waste generated by 95%.
Details of Reductions
Additional Information :
Potential to save as much as $1.2 million annually over a comparable grade purchased acid.
