This study elaborates an enzyme cocktail from Bacillus halodurans applied for the biobleaching of unbleached and ODL (oxygen delignification) agro based pulp in the R&D set up of Shreyans Paper Mills Ludhiana, India, upscaling from 5g (at lab scale) to 100g odp (oven dried pulp).In case of ODL pulp, enzyme cocktail pre-treatment reduced the chemical usage by 40%, yet increasing brightness (2.24%), tensile strength (20.96%), burst factor (5.1%) and tear factor (8.2%) with reduction in kappa number (4.54%). The enzyme cocktail technology can make the paper manufacturing process greener, safer, economical and eco-friendly and may replace big budget ODL technologies.
