ABSTRACT:
In this present paper a study has been carried out to develop an approach of minimum impact on environment during pulping and bleaching of Eucalyptus tereticornis. A new chemical additive (LpH) was used during pulping followed by single stage oxygen delignification and H-H-P sequence produced a pulp of higher pulp-yield, low kappa number, high brightness and better strength properties. In comparison to traditional modified cooking for lowering lignin content in pulp which are capital intensive additive pulping using a new chemical additive was preferred as a low cost alternatives. Among the addition of various doses of chemical additive the best results were obtained at 0.5% chemical additive dose .So the optimized condition for additive dose addition was 0.5%. In adopting bleaching sequence, OHHP sequence gave better strength properties, brightness in comparison to CEH sequence.
