Urban miner Sortera raises $45 million USD to pull aluminum from the scrap pile
Sortera Technologies, founded in 2020 by Nalin Kumar and Manuel Garcia, is emerging as a major U.S. circular-industry player. Led by CEO Michael Siemer, the company uses AI and advanced sensors to turn scrap metal into high-value aluminum alloys. Its new ~$45 million funding round signals investor appetite for industrial decarbonisation—where emissions cuts come not from PR-friendly solar installs, but from upgrading the materials that power EVs, solar frames, and construction.
