The provided diagram delineates the process of recycling used paper to new, usable paper products through four main stages: making pulp, filtering, cleaning and producing recycled paper.
Overall, the process involves cleaning and transforming the original pulp created from used paper through a series of chemical treatments and mechanical processes to suitable pulps which is then utilized for the final production of new paper products.
To commence, used paper from miscellaneous sources are transported using a conveyor belt and are soaked in a concoction of water and chemicals to create unfiltered pulp. Afterwards, this mixture is then passed through a filtering process, where unwanted contaminants are removed, leaving filtered pulp. Subsequently, the processed pulp are submerged in a tank of water and soap, which utilize an air pump to effectively separate ink particles from the previous filtering process and rid of any possible remaining impurities, resulting in clean and suitable pulp for the final stage of production. The qualified-for-production but wet pulp is then put through a heating process which removes water and is then pressed into rollers, resulting in readily usable paper products.
