The flow chart shows how waste paper is recycled. Overall, it is easily apparent that there are four main steps in this linear process, from the initial making pulp stage to the eventual production of recycled paper supported by the extensive use of machinery.
At the first stage of the paper recycling production, numerous discarded paper boxes are conveyed along a transport belt before being dropped into a tank filled with a mixture of water and chemicals to break down into unfiltered pulp. Next, this pulp undergoes a filtration process to create filtered pulp in a large container followed by a stage of cleaning.
In stage three – the washing process, the filtered pulp experiences two mini-phases of cleaning, including washing firstly in a combination of air, ink, water, and soap, and secondly in a mix of water and chemicals to finally produce cleaned pulp. The final stage in the manufacturing is that this pulp is poured onto another conveyor belt, where a drying process occurs facilitated by heated rollers so that removing water and making the end product: the cycled paper
