Energy - indispensable for the production of wafers
A significant part of the transformation process of the purchased silicon into a wafer takes place at high temperatures and in air-conditioned clean rooms. As this requires a lot of energy, wafer production is an energy-intensive industry.
By far the most important form of energy for Siltronic is electricity. Siltronic also requires steam, heat, natural gas and diesel for its production processes, albeit in comparatively small quantities.
Energy efficiency measures
In order to reduce energy intensity, projects are initiated and implemented to reduce specific energy consumption – for example through improvement projects in the areas of lighting, by adjusting cooling water requirements or by optimizing production processes. The key figure "efficiency of energy use" is regularly reported to the Management Board and target values are set annually. The company-wide energy management system at the Burghausen, Freiberg and Munich sites is certified in accordance with the ISO 50001:2018 standard.

RE100: Focus on renewable energies
To achieve its climate targets, Siltronic is committed to gradually increasing the proportion of renewable energies to 60 percent by 2030 and 100 percent by 2045.
RE100 | 2030 | 2040 | 2045 |
Share of renewable energy | 60% | 90% | 100% |
To underpin its commitment to renewable energy, Siltronic joined the RE100 initiative in November 2023. RE100 is a global corporate initiative that promotes the exclusive use of renewable energy. With its membership, Siltronic wants to contribute to removing one of the biggest obstacles to global decarbonization: the insufficient amount of green electricity available in many energy markets.
