Preservation Technologies Japan

The "Bookkeeper " deacidification technology is a technique developed by Preservation Technologies L.P., headquartered in Pittsburgh, Pennsylvania, Saitama City's sister city, which has an international patent, and is an innovative preserving technology for paper products for extending the life of paper books, documents and other paper materials by neutralizing the acids of acid-based paper so that cultural and historical artifacts can be transmitted to the future. Preservation Technologies L.P. has undertaken mass deacidification of acidic books from national and public libraries, archives and university collections in the United States and around the world from 1995 to today. Our company has established a total of 7 Bookkeeper mass deacidification plants in the U.S., Canada, the Netherlands, Poland and Spain.

We have been utilizing an incubator office space in the Sonic City Building from the Saitama International Business Support Center (SBSC) from April 2007, established Preservation Technologies Japan as the Japanese affiliate of our company, then launched our 8th mass deacidification plant in the world in Saitama City in March 2008. Saitama Prefecture and Saitama City are extremely dedicated to attracting companies, and we thank them for introducing us to business locations and personnel, as well as for their strong support. Saitama City, with its excellent transportation access to Tokyo, also makes it a favorable site location.

The number of people who could read rose rapidly in 19th century Europe, leading to a tremendous increase in the demand for paper (books), and with this came mass production of what had been handmade paper made from linen and cotton waste cloth to paper made from wood pulp. Acidic substances (aluminum sulfate) used to prevent ink from exuding from printing and bleaching chemicals were added in mass quantities, and while this is perfect for printing, this fragile, short lived acid-based paper was widely distributed. Books created from this type of paper are now continuing to deteriorate slowly on the bookshelves of libraries and archives. It is not an exaggeration to state that most books published from the 1850's to the 1980's are made of acid-based paper until alkaline-based paper became popular thereafter.

Nowadays, the concept of "Media Conversion" whereby book materials that have deteriorated are saved as microfilm or digital record has appeared, but "preserving original works" to transmit original materials to future generations has reached a point of common understanding in the world's libraries and archives. Simply put, preserving original works using media conversion and deacidification technology functions as a double layer of protection.

The development of deacidification technology for paper products began in earnest in the 1970's, but a variety of negative effects such as the safety and cost of treatment chemicals as well as treatment time arose. The technologies in use today were almost all developed in the 1990's. The BookKeeper deacidification technology is a safe technique for collectors and users because of its chemically inactive on all materials used for books and documents such as paper, cloth, leather and metals, while other technologies remain many problems such as paper color change and odor. Magnesium oxide particles adhere between the paper fibers with Bookkeeper deacidification technology, which neutralizes acidic substances that exist in the paper or are transferred from the air, which extends the paper use life 3x to 5x.

There are many factors that contribute to paper deterioration. Acid is one of the factors for the deterioration of acid-based paper, but temperature, humidity, biological damage, and physical damage caused by handling are major reasons for materials deteriorating. Our company has deployed a consulting business made up of specialists who provide total services for materials storage such as providing information on storage methods of important archives.
