Today, Via is deploying its technology in pilot trials at pulp & paper facilities to eliminate 100 million metric tons of CO2 by 2050. Via’s innovation is a highly selective and robust membrane filter that replaces the energy-inefficient heat-based separations in industrial processes. Spun out of MIT’s Department of Material Science & Engineering, Via has scaled up the technology by more than 10 million times and demonstrated working prototypes at a commercial scale. | $1M | Grant | Oct 14, 2020 |  |
