The diagram illustrates the procedure involved in the production of recycled paper, highlighting each stage from the initial collection of used paper to the final output.
Overall, the process comprises several distinct phases, beginning with the preparation of used paper and culminating in the creation of recycled paper through a series of treatments and mechanical processes.
Initially, the recycling process commences with the collection of used paper, which is transported via a conveyor belt into a designated machine. In this machine, the paper is treated with a solution of water and chemicals, facilitating its transformation into pulp. Subsequently, the pulp undergoes filtration, during which an arrangement of clean water and soap is introduced. This step is crucial in removing ink from the paper, and it is aided by an air pump that helps to ensure a thorough cleansing.
Following the purification of the pulp, it is subjected to a drying phase utilizing heated rollers. This method effectively removes any remaining moisture, resulting in the final product: recycled paper. The entire cycle, as depicted, is emblematic of the recycling process as it existed in 1989, demonstrating the systematic approach taken to repurpose used paper into a reusable commodity.
