TST Inc. Partners with Hydrova for Zero-Waste Aluminum Dross Recycling

TST Inc. is proud to announce its partnership with Hydrova to pilot its innovative technology for zero-waste aluminum dross recycling. In this pilot project, Hydrova will convert aluminum dross from TST’s aluminum recycling facility into valuable products including aluminum, fluxing salts, aluminum oxide, and green hydrogen, leaving zero waste behind for landfill.

This marks a major advancement from traditional technologies, which only recover aluminum and leave the remaining salts and oxides for landfill. Aluminum and fluxing salts are key raw materials for TST’s aluminum recycling operation.

The TST team is thrilled to partner with Hydrova to to create a circular economy in which aluminum recycling byproducts are fully repurposed in a closed loop and kept out of landfill.
