Environmentally friendly production of reinforcing fibers for waste paper packaging papers

Project

Development of an environmentally friendly process for a reinforcing fiber for waste paper packaging papers.

The decline in consumption and production of graphic papers has the consequence that the influx of high-quality fiber material into waste paper recycling declined. With a suitable process, high quality but low-cost primary fibers could be recovered for the reinforcement of waste paper.

Background and Objective

The aim of the project is the development of a straw-based pulping process for the production of high-yield pulp, which can be used to improve the strength properties of recycled paper-based packaging materials.

Approach

The research project will investigate two environmentally friendly pulping processes for straw. In the carbonate digestion, an inexpensive, very environmentally friendly chemical is used with sodium carbonate; the steam refining process can ideally be  applied without chemicals. Both methods and method combinations are tested and adapted for the application.
