AquaMetals is building the plant at the Tahoe Reno Industrial Center east of Reno where Tesla Motors is building its electric battery factory.
The US Department of Agriculture guaranteed a USD 10 million business loan for the Oakland-based company to complete the world's first commercial-scale electro-chemical lead battery and recycling plant.
AquaMetals officials say the technology they call "AquaRefining" is more efficient and environmentally friendly than traditional recycling.
USDA Rural Development spokeswoman Kelly Clark told the Reno Gazette-Journal that it uses a new water-based process to remove the lead instead of smelters that create toxic waste.
