Research Projects - Deinking, 1994 Recycling Symposium Proceedings
Lorenzo Marchildon
The recent application of deinking as a source in the production of cellulosic material has considerably upset the “Know how” of Canadian producers of newspapers and other types of paper. This new technology brings benefits but also problems. Lets mention among others the following problems, encountered in the deinking process, in relation with the different types of ink used in printing, the diversity of basic papers and the design of multiple arrangements of deinking equipments, etc. Since several years we realized different research projects oriented toward the development and application of new deinking technologies aimed to improve the aspect of deinked pulps.
