Abstract:
India is a Agriculture based country that produces 20-25 million tonnes air dried bagasse every year. Each tonne of
sugarcane yield 150-160 kg of air dreid bagasse. Bagasse is an important raw matrial resources for pulp and papermaking in India. It has all the requiste properties to replace the conventional raw material like bamboo and wood for economical
manufacturing of high grade of paper.
Conventionally, bagasse is being, cooked with soda to a reasonable Kappa No ranging between. 20-24. The addition of a small fraction (0.1% on o.d. basis) of AQ has helped to reduce the Kappa Number of the pulp significantly. This pulping process is ecofriendly due to absence of sulphur.
The oxygen delignification is done before E.C.F. bleaching stages. The main theme of the study is production of bleached paper by using E.C.F. bleaching sequences and also to undertake environmental impact of this process.
