Idorsia’s primary environmental sustainability goal is to reduce our environmental impact to help ensure a safe and healthy environment for present and future generations.


Due to the nature of our activities, our environmental footprint is not as substantial as in other industries. However, we take our responsibility very seriously and are continuously working to further reduce the environmental impact of our operations.

Although our business is not water-intensive, we are continuously working to minimize the use of this precious resource. Water is used for a variety of purposes, such as laboratory experimentation, drinking water, facility cooling, and cleaning and maintenance operations. Our facilities are built to the latest standards and include many features designed to minimize water use (e.g. tap sensors). We strictly adhere to all regulations concerning water quality and potential impacts on water resources.

We work to eliminate waste as far as possible. When this is not possible, we aim to reduce waste and recycle to mitigate environmental impacts. Idorsia’s hazardous waste (as defined by local regulations) stems from our research activities in Switzerland. It is sent off-site for recycling, reuse, treatment or disposal. Volatile organic compounds (VOCs), used in our research facilities, may have a negative impact on the environment. To minimize emissions of VOCs, our high-performance liquid chromatography (HPLC) units and waste hoods are equipped with absorption filters which retain VOCs. Most of our non-hazardous waste – plastic, cardboard, paper and other commercial waste – is generated in our offices and catering facilities and is recycled whenever possible.

Reporting for 2018

Following the demerger from Actelion Pharmaceuticals Ltd in mid-2017, Idorsia intends to report data on its carbon usage, water consumption, and waste generation at Headquarters for 2018 in its Annual Report.
