Energy is an essential requirement for overall development of the nation. Pulp & Paper Industry in India has complex structure of old and new plants having diversified technology with varying raw materials and producing different grades of paper. This significantly affects the energy requirement of the mills and therefore results in wide variation in energy consumption pattern.

The Union Cabinet had approved the National Mission for Enhanced Energy Efficiency (NMEEE). The Mission will usher in the four new initiatives to significantly scale up implementation of energy efficiency in India. The flagship of the Mission is the Perform Achieve and Trade (PAT) mechanism, which is a market-based mechanism to make improvements in energy efficiency in energy-intensive large industries (known as Designated Consumers) making them more cost-effective by certification of energy savings that could be traded.

Global concerns about climate change and declining resources mean that major companies must do their best to produce and use energy as efficiently as possible. Paper industry as a sector consume approx. 7.5-15% of the total energy consumed by the industrial sector depending upon the region & operational parameters.

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.

Purchased energy and energy-related capital investments represent major production costs in the Pulp and Paper industry. The paper aims in bringing out the stages of improvement in the energy scenario at SPB (Seshasayee Paper & Boards Ltd.).

With GDP growth for India projected to be 7%-9% annually for the next several years, the demand for growth in every sector including the Indian pulp and paper is inevitable. However, with ever increasing demand on pollution control, the paper industry in India has been looking to grow within the bounds on environmental compliance.

The pulp and paper industry is water intensive among major chemical process industries. Water is the medium where all the pulp and paper making process are carried out and used as vehicle to transport the pulp in the mills from one unit operations to another. A major fraction of water used becomes contaminated during various processes.
