Speaking at the site’s official announcement, Irish Prime Minister Micheál Martin said: “I welcome today’s very significant announcement from the Life Science business of Merck KGaA, Darmstadt, Germany, which underlines the company’s commitment to doing business in Ireland. This investment, the largest in the history of the Life Science business, speaks volumes about our capacity to provide the right conditions for multinational organizations to grow their operations. Ireland’s development of a strong life sciences ecosystem has been one of our greatest economic successes. I am delighted that the company has chosen Cork for its latest investment.

At Blarney Business Park, the Life Science business is going to build a new filtration manufacturing facility for almost €150 million.

The announcement follows a €36 million investment at the same site in 2021 for a second lateral flow membrane manufacturing product line. Now formally open, this facility produces lateral flow membranes, most commonly used in rapid diagnostic testing for rare diseases such as dengue fever, malaria and Ebola. They are also a key component in rapid antigen tests, which are used for the detection of COVID-19.

The membranes also serve the Process Solutions business, which is one of the “Big 3” growth drivers for the company and markets products and services for the entire pharmaceutical manufacturing value chain. Merck KGaA, Darmstadt, Germany aims to increase its Group sales to approximately €25 billion by 2025. To achieve its growth targets, the company plans to increase its total investments between 2021 and 2025 significantly compared with the period from 2016 to 2020.

The Life Science business sector is continuing to invest in products and technologies across its portfolio that are key to manufacturing novel therapies and vaccines, including single-use solutions, high-potency active pharmaceutical ingredients (HP-APIs) and novel modalities, such as antibody-drug conjugates (ADCs) and viral and gene therapies (VGTs).

Over the next five years, the company will implement investment programs worldwide. Target countries include Germany, China, France, Switzerland, Ireland and the USA. All expansion projects include clear targets for water consumption, waste management, and energy efficiency to support the company in meeting its goal to be climate-neutral by 2040, in line with its sustainability strategy.
