The flow diagram illustrates stages of the process about how to renew waste paper.
We can clearly see that the sources of the raw materials come from financial institutions such as corporations and banks. Moreover, it requires six distinct steps to turn those papers into be usable.
At the first stage of the process, waste papers are collected, then sorted by hand. All the graded and unsuitable ones will be removed. After sorting, those papers are delivered to the paper mill, where they pass through several steps from cleaning, pulping to removing of other insects, for example, staples. The resulting products become pure.
The fifth step involves the activity called de-inking. At this point, papers are continually demolished of inks and glues. At the six stage of the process, the papers are transferred to the particular machines to manufacture the end products. After various changes and removals, the usable papers emerge.
