At CSL Behring, we recognize the importance of conducting our operations in an environmentally responsible manner.

Energy, water and other natural resources are essential inputs to the production of our life-saving therapies. Our manufacturing processes, and the packaging and transport of our medicines, generate greenhouse gas emissions and waste. We are committed to minimizing these environmental impacts without compromise to the safety, quality and affordability of our medicines.

CSL Behring’s commitment to the environment is set by the Board and articulated in our Code of Responsible Business Practice. Our Global Environment, Health, Safety & Sustainability Policy and Statement on Climate Change provide further guidance to management and staff. These are critical elements of our enterprise-wide Environment, Health, Safety and Sustainability (EHS2) Management System.

We measure our environmental impact and intensity performance against a number of key indicators. Performance trends for our manufacturing sites are detailed in the Environment section of Our Corporate Responsibility Report


Environmentally friendly processes

CSL Behring AG’s products are manufactured using processes that are as environmentally friendly as possible. We place great store by energy-saving and futuristic technologies and measures.

For example, the ethanol that we use in large quantities for production is cleaned in a recycling plant using distillation and can be used again. The use of recycled ethanol means that we need to buy less ethanol and transport less to CLS Behring AG. This saves a significant number of truck kilometers. A new plant also contributes to energy efficiency. Unlike existing plants, it needs less steam in order to obtain the same quantity of ethanol from a diluted solution using rectification. This also results in less natural gas being used to produce steam.

Ethanol that can no longer be used in production is turned into biogas in the digestion tower of the wastewater treatment plant in Bern and is refined in a processing plant. The biomethane produced in this way is fed into the regional ewb natural gas network and is used for such applications as fuel for the buses in the city of Bern.

Cold wastewater from internal water processing is used in production systems or in heat exchanger towers for cooling purposes. This saves considerable quantities of water and energy.

Furthermore, waste heat from hot water treatment, steam production or refrigeration plants is also used again where possible. It is used e.g. for heating office buildings and a nearby school, or for undersoil heating at the neighboring Stade de Suisse.
