The diagram illustrates the stages involved in the recycling of used paper.
Overall, the process encompasses a series of distinct phases, namely pulping, filtering, cleaning, and paper making. Specifically, it starts with a conveyor belting moving used paper and the final stage is when the paper is fully recycled.
Initially, used paper is conveyed on a belt to a vat, where it is mixed with water and chemicals to break it down into fibers, commonly referred to as unfiltered pulp. Following this, the substance is subjected to a filtration process to eliminate larger particles. The next phase is deinking, which involves the filtered pulp being treated with a mixture of water and soap to remove any remaining impurities. During this stage, an air pump is introduced to create bubbles, causing the ink to rise to the surface, which is then removed through a dedicated pipe. This step is essential for ensuring that the final product is free from any residual printing substances.
Once the pulp is cleaned, it is formed into rolls of recycled paper through the utilization of heated rollers, which expels any remaining water and facilitates the solidification of the paper into its final form.
