'Orca' World's Largest Plant To Clean Air Starts Work: Switzerland

To fight against climate change and reduce carbon dioxide (CO2) from the air, the world's largest plant named ''Orka or Energy'' has become operational on September 8. Reportedly, Orka is built by Switzerland's Climeworks and Iceland's Carbfix and reportedly turns carbon dioxide into rock. While running at its capacity, it can suck 4,000 tonnes of CO2 every year that is equal to the emission from about 870 cars.
