Entire blocks of newspapers and books can be treated with the Improved Vienna Method, which is cost efficient, environmentally friendly, and saves energy and resources. This method helps to preserve newspapers and printed materials, which are decomposing in libraries because of the industrial paper they are made from.
Industrial paper contains acid destroying the cellulose chains in paper.
Through the Vienna Method, the acid is neutralized by soaking the paper in a watery solution, while it is simultaneously strengthened.
