Cardboard bales for paper recycling. Stockpiled bales of cardboard await recycling at a paper mill. Both high-grade and low-grade recycled paper can be produced depending on how clean and de- inked the final paper product must be. In a low- grade recycling process, tissue paper or cardboard products may be the end result. High-grade treatment may produce high quality recycled paper such as computer listing paper.
