Sample Answer
The diagram details how recycled paper is made. Looking from an overall perspective, it is readily apparent that the process involves three main stages beginning with initial collection and transportation, followed by cleaning and processing, and lastly the rolling of the final product. The entire procedure is completely man-made and involves mechanical and chemical steps.
To begin with, used paper is collected and placed on a conveyor belt which carries it to a processing plant. There, water and various chemicals are added to form an unfiltered pulp. This pulp is then filtered to remove water and separate unwanted materials.
Following the initial filtering, the filtered paper pulp is sent via a tube into a container that contains water and soap for further purification. Air is pumped in, which helps remove ink from the mixture. Additional cleaning using water and chemicals takes place before the pulp moves to the final stage.
In the final stage, the cleaned pulp is transferred to a conveyor belt with heated rollers. These rollers flatten the pulp, remove excess water, and convert it into recycled paper rolls ready for use.
