Issues in Recycled Paper and their Influence on the Printing Capability

Abstract

The effective utilization of waste paper has been strongly required in regards to conserving the global environment and the growing solid waste issues. Japan is one of the leading countries in utilizing waste paper in the world. Waste paper has already accounted for more than half of the fibrous raw materials in manufacturing paper and paperboard. We are concerned that the printing capability could deteriorate because of ink specks, sticky material in wastepaper and the decrease in recycling paper strength. However, the progress of waste paper recycling technology will overcome those problems. Also, the trend of recycling technology in recent years is mentioned.
