In researching this topic for a paper, I found a reference to a collection from the Los Alamos National Laboratory (LANL) thought to be infected with hantavirus that was treated with heat. The procedure used on the LANL materials involved placing the materials in a microbiology incubator at temperatures in excess of 60C for a minimum of 20 minutes. These high temperatures inactivate the virus by destroying its molecular structure. Warling, R., and F. Bolton "410-Preventing Hantavirus Exposures Where Liquid Chemical Decontamination is not an Option" The American Industrial Hygiene Association. <URL:http://www.aiha.org/abs99/9pos3.html> Although it is not recommended for paper materials to be subjected to such temperatures, the heat method can be an attractive option for dealing with potentially infectious materials. Treatment with heat allows the collection to be batch processed, rather than being cleaned on an item level; it ensures that the virus will be inactive after treatment by denaturing the virus' protein envelope; and it requires the least amount of human exposure. I have quite an extensive bibliography on hantavirus and the various treatment methods if you are interested.
