Abstract

A detailed discussion of synthetic nonionic and anionic surfactant combination based near-neutral deinking is presented. It is shown that by choosing a nonionic surfactant with a desired hydrophile-lipophile balance during pulping and using a small amount of anionic surfactant during flotation, excellent deinking of LEP as well as dye-based inkjet and various other prints are obtained. All the results are obtained without adding any bleaching stage, which can further enhance the results. High flotation yield in the range of 80-85% with minimal fiber loss, as shown by thermogravimetric analysis, is also obtained.
