New Porsche factory uses power of TiO2 to absorb pollutants

As part of a drive towards a ‘zero impact factory’, Porsche has covered sections of its new factory façade with NOx-absorbing titanium dioxide (TiO2).

The factory complex, which is a production site for the Porsche’s first EV car – the Taycan – has surface elements made from aluminium coated with TiO2. This coating works as a catalyst, converting absorbed pollutants into water and nitrate.

Pollutants, such as nitrogen dioxide, are turned into harmless substances as they interact with the TiO2 coating while exposed to low air humidity and sunlight. The test project installed in Porsche’s Stuttgart-Zuffenhausen-based factory features a 126-square-metre façade, which the company says performs the air cleaning equivalent of 10 trees.

“If the evaluation of the results confirms our expectations, nothing stands in the way of using nitrogen oxide-absorbing surface technology on other buildings and surfaces,” says Albrecht Reimold, Member of the Executive Board responsible for Porsche AG’s Production and Logistics.

TiO2 can help ensure better air quality outcomes, providing cleaner and safer air in an increasingly industrialised world. These benefits are not limited to factory spaces and can be applied in a wide variety of locations and scenarios.

Porsche’s aim is for Taycan production to be carbon-neutral, with Reimold stressing that the auto manufacturer is, “consistently pursuing our objective of sports car production completely without any ecological footprint”. TiO2 is set to play a crucial role in achieving this ambitious aim.
