River Street Metal Finishing Reduces Use of Sulfuric Acid

Improves Worker Safety, Reduces Costs

Watch this 2-minute highlight video.

River Street Metal Finishing, located in Braintree, Massachusetts, held a virtual demo event on July 23, 2020, sharing how they are reducing the use of sulfuric acid in the anodizing process.

The company received a TURI grant to purchase a new acid purification system that filters the dissolved aluminum out of the tanks and returns the filtered solution back to the tank. As a result, the reduction of sulfuric acid use is improving worker safety, reducing hazardous waste and saving money.

The company expects to save approximately $1,200 annually in chemical costs due to using less sulfuric acid. With the reduction of hazardous waste generated, the company expects to save an additional $3,800 annually.
