Divisions of the Institute

Recycled Fiber (RCF) Processing Section

In this area the Institute offers complete know-how for Recycled Fibre Processing for its effective utilization as paper making fibre. The section is well equipped with state-of-art facilities to conduct R&D activities and render consultancy and technical services for increased utilization of recycled fibres.

Achievements

Under the project study on "Availability & Utilization of Waste Paper" sponsored by IPMA, CPPRI has proposed an indigenous gradation system. The proposed gradation system covers twenty (20) varieties of indigenously recovered paper grades, which have been classified into nine (IX) groups based on their fiber quality, and fiber furnish. - For details contact CPPRI

Highlights of activities :

Pulmac HD Pulper Voith Floatation Cell

1. Identification and Control of Contaminants :
¤ Gradation of indigenously recovered paper based on fibre quality and fibre furnish composition.
¤ Offers process technology for recycling of Wet Strength Papers and Wax Coated Papers.
¤ Quantification of Micro & Macro stickies across the fibre line to evaluate various unit operations towards contaminant removal efficiency.
¤ Stickies control programme on case-to-case basis

2. Quality Upgradation :
¤ Brightness improvement & color stripping in deinked pulp employing Oxidative/Reductive Bleaching sequence.
¤ Optimization of Bleaching sequence for Newsprint & Writing/Printing paper.
¤ Furnish optimization fro Newsprint and Writing/Printing paper

3. Solid Waste Management :
¤ Disposal/Utilization of Deinking Sludge

4. Technical Services Offered for :
¤ Process audits to evaluate accumulation and generation of stickies and other contaminants.
