Our Engagement for Environment and Safety
Climate change is an environmental factor that is essential for us as a globally active company. For Bayer, the protection of the environment and the safety of our employees and the people living in the neighborhood of our sites are of the highest priority.
Below you will find more detailed information on various sustainability areas.
At Bayer Switzerland, we are aiming for climate neutrality by 2030. To achieve this, we are relying on three strategic levers: process innovations, more efficient plants and building technology, and the implementation and optimization of energy management systems.
The largest share of emissions at Bayer in Switzerland is generated in production in Muttenz: In 2024 it was 23'205 tons of CO2.
Our systematic waste management enables us to keep the consumption of materials as well as the disposal quantities at the lowest possible level. Our targeted waste separation, safe disposal methods and economically appropriate recycling processes contribute to the same goal.
Waste Volume in Metric Tons in 2024
| Production site Muttenz | 26'013 |
| - Chemical waste | 26'000 |
| - Domestic waste | 13 |
| Office site Basel | 14.4 |
We do not have any figures for the Zurich site.
The industrial park GETEC PARK.SWISS AG in Muttenz offers comprehensive waste management. Waste incineration is used to generate energy and to mineralize industrial waste. Hazardous and industrial waste is incinerated, generating heat in the form of steam, hot water and warm water.
The thermal waste gas purification plant with steam generator is used for the incineration of waste gas and waste air streams generated at the site during the production of crop protection products and intermediate products. The pollutant composition requires flue gas denitrification (SNCR) and flue gas scrubbing to comply with the limit values. To minimize the support fuel natural gas, substitute fuel is also burned.
While we consumed around 351 kilograms of PET in 2023, we were able to reduce this figure by 48 kilograms in 2024, bringing the PET volume down to 303 kilograms. Through our recycling efforts, we also reduced the amount of greenhouse gases emitted by approximately 800 kilograms and the amount of crude oil consumed by 217 liters.
We have introduced professional recycling stations and communal printing rooms at our offices in Basel. This simplifies recycling, and the communal printing rooms have minimized air pollution and noise emissions in the offices.
Since 2023 we use water-saving adapters on all taps in the Basel office. These adapters have a water flow rate of just 4.5 liters per minute, which is 1.6 liters per minute lower than before. Nevertheless, the greater utilization of offices resulted in consumption rising to 2.27 million liters, which equates to a year-on-year increase of 100 cubic meters compared to the year before. In 2024, around 2'514 million liters of water were consumed at the Muttenz production site.

At our production site in Muttenz, we use various purification processes and treatment steps for the wastewater. Depending on the ingredients, we combine the processes so that the wastewater is discharged in compliance with the law and directives. Wastewater treatment almost always begins with internal pre-treatment in the production building. For example, solvents are recycled, or pollutants eliminated through distillation or extraction.
At the production site in Muttenz, in 2024 around 205 million liters of water were professionally treated at the production site in Muttenz.
