Among other products made at its plant in Rheinfelden, Evonik manufactures AEROSIL®, which is used in many everyday products such as toothpaste, paints and coatings, and LED lamps. AEROSIL® improves the properties of these products and in many cases makes them more energy-efficient, e.g. as a component of heat-insulating refrigerator doors. AEROSIL® is a white powder and chemically speaking a kind of sand that is produced in a combustion process. This fumed silica is produced from hydrogen, the chemical compound chlorosilane and dehumidified air. Previously, Evonik produced the hydrogen needed for this process using natural gas in the so-called steam reforming process. However, this gives rise to specific CO2 emissions.
