PyroGenesis ( PYRGF ) is developing the FSR for a subsidiary of HPQ.

The PyroGenesis ( PYRGF )-designed FSR pilot plant is now focused on replicating the lab-scale fumed silica product quality and is undergoing a series of optimization tests.

Fumed silica is one of the most widely-used industrial products and is used in personal care items, processed food products and construction materials, a statement noted.

PYR rose more than 3% yesterday, moving it a bit further away from 52 week low levels.
