Waste paper contains much more fillers, adhesives, dyes, polishers, and similar additives that are problematic for conventional paper recycling technologies. A sharp growth of this trend encourages conceptual reengineering of the existing technological processes in waste paper management. In this article, a techno-economic analysis of energy utilization by means combustion, anaerobic fermentation (also accelerated by steam-explosion), and pyrolysis was carried out in a pilot scale.
