Sustainability
Net Zero by 2045
Extra Budget for Process Transformation
“Our most important sustainability goal is to reduce greenhouse gas emissions. We aim to cut those in half by 2030 – we’re talking about absolute numbers, regardless of how much growth we experience. We are starting with our own products and processes to achieve this target. With our investment budget for sustainable process transformation, we support projects that cut greenhouse gases, other emissions and water consumption, or contribute to a circular economy. In the reporting year, we used this budget to approve projects that aim to achieve annual reductions of more than 100,000 metric tons of CO2. In order to support and further promote our employees’ commitment to sustainable process transformation, we started awarding our annual WACKER Net Zero Award, worth 10,000 euros, in 2022. This is our way of recognizing outstanding projects that significantly reduce our company’s environmental footprint.”

Renewable Reductants in Silicon Production
“Silicon metal is one of the most important raw materials for WACKER and is used in the production of silicones and hyperpure polysilicon. The silicon metal produced in Holla, Norway, covers roughly one-third of demand. We are currently expanding the Holla site, which is playing a key role in helping us achieve net zero emissions. The coal employed as a reductant in the production of silicon metal is now being replaced with renewables, such as biocarbon sourced from sustainable forests. The use of biomass is deemed to be carbon-neutral, because combustion releases the carbon dioxide taken up by the plants while they were growing. In the downstream stage, we would like to capture this biogenic CO2 again and either store it permanently or use it as a raw material in the production of chemicals. We will be installing a pilot plant for this in 2023.”

Green Electricity for Electrified Processes
“We are working on switching our production sites to green electricity. We have already succeeded in doing this at our Holla site – among other things by negotiating power purchase agreements with providers of wind and hydroelectric power. In 2022, our Holla site procured all its electricity from renewable energy sources. Over the coming years, we will switch our other production sites to green electricity worldwide. Due to increasing process electrification, our electricity consumption will rise in the next few years despite intensive efficiency measures. That’s why we are working on fossil-free alternatives for steam generation, for example with heat pumps. This will allow us to utilize electricity even more efficiently and avoid fossil fuels such as natural gas.”
