Cl is used to give paper its white appearance and to remove "LigninLignin is a category of complex constitutional polymers that grade key structural materials in the accompaniment tissues of tube-shaped structure plants and few algae. Lignins ar particularly important stylish the formation of cell walls, peculiarly in wood and bark, because they lend rigidity and do not hogwas easily. Chemically, lignins are cross-linked phenolic resin polymers.," an chemical element of wood fibre that yellows paper when exposed to sunlight (as occurs with newsprint). Wood-based paper is brunette in its biological state, as proven by brown paper bags and almost cardboard boxes,

How is chlorine used in pulp and paper industry?
Chlorine in the Bleaching of Pulp and Paper. The pulp and paper industry in Canada contributes significant effluent discharges to surface and marine waters. Chlorine and chlorine compounds are used in the bleaching of pulp. A large number of organochlorine chemicals of widely differing properties are, or have been, produced from this bleaching.
What can be used in place of chlorine?
Alternatives to the use of mo- lecular chlorine, such as chlorine dioxide, result in reductions in the quantities of organochlorines produced, and the degree of chlorine substitution in the organochlorines formed.
Why is chlorine used as a bleaching agent?
Use of molecular chlorine as a bleaching agent results in the formation and release of chlorinated organic compounds, sometimes at concentrations that present an un- acceptable risk to the receiving environment and the food chain.
