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.

The processes in production and the depth of our value chain have a major influence on our energy requirements. For example, the extraction of raw materials for crop protection products and the preparation and further processing of these in pre-production are particularly energy intensive.

The total energy consumption of Bayer Switzerland in 2021 was 490.7 terajoules (108 million kWh).

With 484 terajoules (134,4 million kWh) last year, our production facility in Muttenz is the big energy consumer in our system. For this reason, we are committed and motivated to constantly save energy. Together with the Energy Agency Swiss private sector (Energie-agentur der Wirtschaft, EnAW), we have set these target areas in order to improve every year. 

Bayer's global goal is to rely 100% on green power by 2030. We have already achieved this at our production site in Muttenz: By 2021, we were already using 100 percent CO2-free electricity from renewable sources.

The office location in Basel had an energy consumption of 4.6 terajoules (1.3 million kWh) last year. For heating, we currently obtain district heating in a mix of:

  • 44% waste incineration (CO2 neutral, 50% of the waste is biodegradable, such as our Naturesse coffee cups)
  • 35% natural gas
  • 17% wood combustion (CO2 neutral, thanks to wood from local, sustainable cultivation)
  • 3% sewage sludge
  • 1% heating oil

We are examining whether the share from CO2-neutral sources of 61% can be further increased.

Since January 2021, we are sourcing in Basel energy exclusively from renewable sources in Switzerland. Since March 2021, this has also been the case in our offices in Zurich.

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 2020 it was 5,876 tons and 99.8% of this was CO2. 

In 2022, we have completely reworked our car policy and adjusted our vehicle selection. In the future, the management will exclusively use electric and hybrid electric vehicles and these will also be prioritized for our field employees. We support the installation of the necessary infrastructure – both at the office locations as well as at the home of employees with company cars.

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.

Production site Muttenz 24,743

We do not have any figures for the Zollikofen and Zurich locations. 

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. 

By eliminating PET bottles in all our meeting rooms, we have drastically reduced our PET quantity within two years. In 2018, the amount was still 3,670 kilograms, which was reduced by 20% to 2,889 kilograms in 2019. In 2020, the rate was still 411 kilograms – the decrease is largely due to the COVID 19 pandemic. In 2021, a total of only 183 kilograms of PET was recycled.

Sustainability Fact 2 Basel Recycling EN

We have introduced professional recycling stations and central printer rooms in the Basel offices. This has simplified recycling and minimized air pollution and noise emissions in the offices thanks to the central printer stations.

At the production site in Muttenz, 609 tons of metal and zinc salts were recycled in 2020.

At the production site in Muttenz, the cooling water for production is treated in cooling towers (hybrid coolers) on the roof and fed into a closed circuit from there. In 2020, we installed an additional fourth cooling tower.

The office location in Basel used around 55% less water in 2020 than in the previous year due to the COVID-19 pandemic. In 2021, around 54.6% less water was again less water was needed than in 2020, as the workforce there only worked from home. The water comes from local groundwater and Rhine water sources.

Water consumption in million liters 2021
Production site Muttenz 3,507
Office site Basel 0,912

We do not have any figures for the Zollikofen and Zurich sites.

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 2021 228 million liters of water were professionally treated at the production site in Muttenz. Our laboratory at the Muttenz site tests the wastewater for constituents and biodegradability so that we can decide how to dispose it properly – directly to ARA Rhein for final biological cleaning or first to AVORA for further pre-treatment.
