How is Paper Recycled by DTG Recycle near Redmond?
Having gained a better understanding of paper recycling, you might be curious about the process behind it. Look no further, here’s a comprehensive guide on how companies recycle paper in Redmond.
1. Collecting Used Paper
The initial stage in paper recycling is to gather discarded paper that can be sent to Redmond recycling centers. To keep it separate from other used products, paper is put into a designated recycling bin. It is important to note that contaminated paper, such as paper soiled with food, grease, or harmful chemicals, can’t be recycled and will be redirected to a landfill. DTG Recycle does not offer a pickup service to recycle paper in Redmond, WA.
At the recycling center, the papers undergo sorting and separation to distinguish between those that can be recycled and those that must be discarded. Upon being accepted at the Redmond recycling facility, the papers are further categorized based on their quantity and paper value by evaluating the materials used to create them. In many cases, the papers are sorted according to their surface treatment and structure. For example, glossy magazine paper is handled differently than a standard piece of printer paper and needs to be sorted separately.
3. Shredding and Pulping
Once the paper has been sorted and removed of all contaminants, the shredding and pulping process commences. The paper is shredded into tiny pieces before adding water and other chemicals to extract the fibers more thoroughly. This results in a mushy pulp, which serves as the primary raw material for creating new products from recycled paper. The pulp undergoes a rapid cleaning procedure to eliminate any non-paper items, such as paper clips and staple wires, before moving on to the following stage.
At this stage, the pulpy mass is screened by pushing it through screens with various shapes and sizes of spaces and holes. The objective of this step is to eliminate any remaining contamination from the pulp and filter out any unwanted objects.
5. De-Inking and Bleaching (Optional)
De-inking is a process that involves washing the pulp to eliminate printing ink, glue residues, and other adhesives. More extensive cleaning is required for larger and stickier particles, which is known as the floatation process. The pulp is introduced into a floatation vat, where air and surfactants are added. The ink and other particles attach themselves to the air particles and rise to the surface, where they are extracted.
Bleaching is only necessary if the goal is to produce white paper. During this stage, hydrogen peroxide is used to increase brightness, purity, and whiteness. Oxygen or chlorine dioxide is also used alternatively. However, the bleaching process is not necessary if the pulp is being recycled into cardboard.
6. Rolling and Drying
The last step in the paper recycling process is the rolling and drying stage. The pulp is fed through large rollers to extract any remaining moisture before being passed through heated rollers and wound onto a massive roll. These rolls can be as wide as 30 feet and weigh up to 20 tons. The pulp is then subsequently shipped to various manufacturers for use as recycled paper products.
