I recall being a kid and relaxing in class learning about all of the essential things in everyday life. You know, D.A.R.E., Smokey the Bear, etc. I recall researching recycling and its impact on environmental surroundings, but I can't recall any animated character to visit together with it. Although my memories are a bit vague about what was taught to us, I still know that recycling is important and plays a significant role within the health of our environment.
A great friend of mine's father was an engineer at a local landfill so for just one of our field trips, we visited his workplace. I recall the tour, seeing the large machinery sifting through the municipal solid waste materials, and being disgusted by the smell of it all. On our visit, it had been stressed how important it had been to dispose of recyclable materials such as paper, plastic, glass, etc. properly so they wouldn't end up in a landfill.
Luckily for all of us, a long time ago someone developed a process to recycle certain materials so they wouldn't be buried in the ground leaving a horrific odor for anybody inside a surprisingly far proximity to smell. With regard to this post, I will focus on the 10 step process of how paper is recycled and in a later post I will discuss the recycling process for other recyclable materials.
Please see the steps below for the paper waste recycling process:
Step one: Sorting Paper Waste- Removing all paper which has contaminants such as food, plastic, metal and other trash can be carried out by hand. Many businesses will examine their paper easily with your tools as those built by MSS, Inc..
Step two: Collection and Transportation- Your paper trash can automatically get to a local recycling center, recycling bin, or recycling center can pick up.
Step 3: Paper Storage- Paper mills then store the paper until it is needed in the next thing from the process. This paper is then transferred on large conveyors for the following step.
Step four: Re-pulping and Screening- The pulper then chops the recovered paper into small pieces while heating the mixture to interrupt it down into fibers. The fibers are then screened right through to ensure there are no more contaminants.
Step 5: Paper Cleaning- To further clean paper waste, a process called spinner will be carried out. This process will remove heavier, harder to get rid of objects.
Step 6: De-inking- Allows the paper to become removed of inks along with other adhesive materials by using water and air bubbles.
Step 7: Refining, Bleaching, and Color Stripping- The recycled fibers are separated into individual fibers to allow them to be further prepped. If the fibers contain a color they'll be stripped from the dyes and when the recycled paper is to be white, it will likely be bleached with hydrogen peroxide.
Step 8: Paper Making- The pulp is finally combined with water and chemicals until it is positioned on a screen which drains the pulp water. Once drained the pulp is in a sheet and passed through heated metal rollers that dry the paper.
So the next time you plan on just throwing away that paper rather than recycling it, think about this process and the nasty odor people are instructed to smell when someone chooses not to recycle paper waste.
