The flow chart illustrates the recycling method of waste paper. Obviously, there are six main stages in the waste paper recycling process. The first step of this process includes collecting discarded paper, and the last step is making usable paper. In the early stage of the process, waste paper is collected from individuals or companies. The process continues, and the workers sort the paper and remove the unsuitable paper. Then, the paper is transferred to the paper mill to prepare for the next step. In a paper mill, paper is washed and ground into powder. This step involves removing other materials, such as needles. The process continues with a step called "deinking", in which all ink and glue are removed from the paper. In the last process, the paper is put into the machine, and then new paper is finally produced and ready for reuse.
