Silicone fluids manufactured from renewable raw materials
The international inspectorate TüvSüd has recently certified the Wacker Group’s mass balance method for tracing renewable raw materials in silicone manufacture. The manufacturer is the first company in the world to produce silicone fluids without the use of fossil resources.
With the certification, the company has a recognized procedure for tracking the use of renewable raw materials throughout the production process as far as the end product. Currently, the chemicals producer also uses plant-based methanol in its production processes. Therefore, the company is able to market silicone fluids exclusively manufactured with the help of biomethanol.
Silicone fluids produced with biobased or petrochemically based methanol are chemically identical. However, biomethanol based silicones have a significantly more favorable carbon balance, since no fossil raw materials are involved in the methanol manufacture. According to Wacker’s calculations, around 1.6 metric tons of carbon dioxide can be saved per metric ton of silicone fluid. Silicone production requires not only methanol, but also silicon, which is derived from quartz rock or sand. Silicone fluids from biomethanol are thus produced entirely from mineral- or plantbased raw materials.
