As far back as 1990, the Swiss National Library and the Swiss Federal Archives identified the need to subject affected documents to a conservation process. At that point, the project to build a deacidification facility began. With many years of wide experience in the field of cellulose chemistry and analysis, Nitrochemie is the ideal partner for implementing this project. In a joint undertaking, one of the world‘s most technologically advanced and largest facilities for paper deacidification was commissioned in 2000. With its two treatment chambers, the plant is capable of treating 120 tonnes of material a year.

A new plant for deacidifying valuable documents was commissioned in Aschau am Inn, near Munich, in the spring of 2015. Three additional treatment chambers there extend the annual treatment capacity by 180 tonnes
