Enzymatic deinking as an environmentally friendly solution for recovered paper recycling (BIO-DEINKING)

Objectives

Deinking is a recycling technique that can produce high quality recycled pulp from recovered papers. Ink detachment is an important step of the process. Some inks are difficult to detach and lead to a lower pulp quality.

Technical Approach

The objective of this project is to develop appropriate environmentally friendly enzymatic deinking to address deinking difficulties with respect to ink detachment. Bio-deinking is an alternative to prevailing solutions requiring more chemicals and energy.

Expected Results

I. Direct Results

Development of a new deinking technology
Selection of efficient enzymes for deinking according to paper grade and print technology
Determination of operating conditions for enzymatic deinking
Evaluation of enzymatic deinking on paper production rate, paper quality and water system quality

II. Indirect Results

Positive effects on the environment: reduced chemicals consumption, reduced energy consumption, lower rejects of dissolved materials (COD)
Help to increase the utilisation rate of recycled pulp in higher grade papers
New market for enzyme producers

Applications

Generation of knowledge for new applications dealing with fibre modification.

Two-stage deinking pilot plant. Enzyme in deinking reduces conventional chemical use, thus reducing envionmental impact of an alkaline deinking system (COD, etc)
