The illustration shows the process of paper production and subsequent recycling.
Overall, the process involves four main stages, starting with the processing of radiata pine thinnings, followed by the production of paper, its use in newsprint, and final recycling, thereby closing the production loop. Also, the process is a complex one, which requires much time and equipment to complete.
Focusing on the “Plantation to paper” process first, radiata pines are thinned. After being thinned, they are placed onto a de-barking drum and then passed through a chipper. Next, this chipped wood is cleaned by a thermomechanical refiner. Once refined, the material is placed in a paper-making machine to produce the finished paper.
Turning to recycling, once collected, the scrap paper is passed through a de-inking machine. After de-inking, the materials are placed onto a cleaning and fine screening automation. Finally, the cleaned materials are passed through thermomechanical and recycled pulp mix to manufacture the recycled paper.
