Ionisos

Ionisos is a prominent European operator in the cold sterilization sector, providing essential services to the medical, pharmaceutical, cosmetics, and food packaging industries. The company's lineage traces back to 1956 with the establishment of the Centre Lyonnais d'Application Atomique, a pioneering entity in product treatment using ionizing radiation. The modern company, Ionisos, was formally established in 1993 following a merger between Conservatome and Amphytrion.

The firm's business model is centered on providing outsourced sterilization and cross-linking services. It generates revenue by treating products for its diverse client base of over 1,000 customers, which includes major multinational companies involved in medical and pharmaceutical devices. This service is critical for clients who manufacture single-use products that cannot withstand the heat or humidity of traditional hot sterilization methods. The market for these services is propelled by non-cyclical factors such as an aging population, rising demand for medical services using single-use items, and increasingly stringent regulations governing product sterilization.

Ionisos offers a comprehensive suite of cold sterilization technologies, including gamma ray, electron beam (e-beam), and Ethylene Oxide (EO) treatments, making it one of the few providers in France with this full range of capabilities. Gamma sterilization uses Cobalt-60 to emit rays with high penetration capacity, ideal for treating high-density products on full pallets. E-beam sterilization employs accelerated electrons for products in smaller cartons, while Ethylene Oxide sterilization uses gas in a vacuum chamber for treatment. Beyond sterilization, which constitutes the majority of its business, the company also provides polymer cross-linking services to enhance the physical properties and durability of materials like thermoplastic films used in various industries, including automotive.

Strategically expanding its European footprint, Ionisos has grown through a series of acquisitions and the establishment of new facilities. The company operates a network of specialized sites across France, Spain, Germany, Estonia, and Switzerland. This expansion has been supported by several private equity firms over the years, including Naxicap Partners, Agilitas, Ardian, and as of 2019, 3i Infrastructure. The management team, including President Michel Gominet, has been instrumental in guiding the company through these phases of growth and transformation.
