Research Progress on the Recycle and Reuse of Wasted Aluminum Substrates of CTP Plates

Recycling and reuse of wasted materials is a key topic in materials research, providing a new material recycling path for green manufacturing. As a national pillar industry, the greening and intelligent upgrading of the printing industry is an inevitable trend in the development of modern printing. To better implement the national “dual-carbon strategy” and cultivate new quality productivity, this paper presents a systematic literature review on the research progress of the recycling and reuse techniques of used aluminum substrates of CTP plates for offset printing. Analysis of existing industry data and literature shows that aluminum substrate of used CTP plates meets the recycle size and required physical and chemical characteristics, but the current research has not yet fully taken into account the integration of technical innovation in the recycling and reuse of aluminum substrate of used CTP plates. Based on material eco-cycling perspectives such as sustainable material utilization design, wasted material recycling device and multi-material fine separation process, this paper provides a unique outlook on the integrated development trend of recycling and reuse of aluminum substrates of used CTP plates, and provides greening case references for the safe management of wasted materials in the modern offset printing industry.
