The utilization of the post consumer paper product in the production of new paper products is increasing all over the world in recent years. The use of enzymes in ecofriendly deinking of the recovered paper is one of the potential enzymatic application in the pulp and paper industry.

A number of studies have already been carried out for the metal analysis of paper mill effluents which are generally using wood and non-wood (bamboo, baggase etc.) as fibrous raw material for paper manufacturing process. This study deals with a paper mill which is using cotton comber and cotton liner as raw material for paper manufacturing process.

Pulverized coal fly-ash has been evaluated as wet-end filler in manufacture of specialty products such as decorative laminate-grade base papers. Fine sized fly-ash is available abundantly as solid waste from coal based thermal power plants. Non-magnetic fly ash particles smaller than 35 um were used as wet end filler.

To meet present day stringent pollution control norms, there was a high stress on paper mills to deliver highest quality work with low operating cost within the budgeted limitations. Keeping this in view, biological treatment procedure is adopted. Use of blend of bacterial colonies in place of conventional urea & DAP dozing have proven to be cost effective solution.
