Paper Recycling Process Link

Paper is one of the more utilized materials that we use in our society. It’s an amazing material that is very versatile in many uses. Although recycling paper seems like a simple process, different types of paper, create different issues when it comes to the recycling process.

In 2011, 66.8 percent of paper consumed in the United States was recycled. Every ton of paper recycled saves more than 3.3 cubic yards of landfill space, and if you measure by weight, more paper is recovered for recycling than plastic, aluminum and glass combined. Paper is a material that we’re used to recycling, since 87 percent of us have access to curbside or drop-off recycling for paper.

The process of recycling paper can be summed up into a few simple steps:

  1. Paper is taken from the bin and deposited in a large recycling container along with paper from other recycling bins.
  2. The paper is taken to a recycling plant where it is separated into types and grades.
  3. The separated paper is then washed with soapy water to remove inks, plastic film, staples and glue. The paper is put into a large holder where it is mixed with water to create ‘slurry’.
  4. By adding different materials to the slurry, different paper products can be created, such as cardboard, newsprints or office paper.
  5. The slurry is spread using large rollers into large thin sheets.
  6. The paper is left to dry, and then it is rolled up ready to be cut and sent back to the shops.

Here Are Some Facts About Paper Grades:

  • Paper Grades – There are five basic paper grade categories, according to theEPA. While these terms may be most useful to paper mills looking to process certain kinds of paper, you may hear these terms once in a while, and it’s possible you’ll need to be able to distinguish between them.
    • Old Corrugated Containers – You might know this as “corrugated cardboard.” It’s most often found in boxes and product packaging.
    • Mixed Paper – This is a broad category of paper that includes things like mail, catalogs, phone books and magazines.
    • Old Newspapers – This one is pretty self-explanatory. Mills use newspapers, a lower grade paper, to make more newsprint, tissue and other products.
    • High Grade Deinked Paper – This quality paper consists of things like envelopes, copy paper and letterhead that has gone through the printing process and had the ink removed.
    • Pulp Substitutes – This paper is usually discarded scraps from mills, and you probably won’t have to worry about running into it, though it may find its way into products you buy.

Some Paper Recycling Curiosities:

  • Once you know what kind of paper recycling is available to you and which types of paper are recyclable, you might still have some questions about paper recycling. Here are a few common items that cause confusion:
    • Shredded Paper – Ever wondered whether shredded paper can be recycled? The answer is yes, though you may encounter some restrictions regarding the size of the shredded pieces and the way the paper is contained. Check with your local recycling program for specific information.
    • Staples & Paper Clips – Believe it or not, equipment at paper mills that recycle recovered paper is designed to remove things like staples and paper clips, so you don’t need to remove them before recycling. It is probably in your best interest to remove paper clips, though, so they can be reused.
    • Sticky Notes – If your local recycling program accepts mixed paper, it will most likely accept sticky notes. Paper mills that process mixed paper are able to remove adhesives. To be on the safe side, check with your local program to make sure sticky notes aren’t a problem.

Aluminum Can Recycling Link

Aluminum seems to be one of the more common materials in the United States in which the public is reminded to recycle consistently. It’s a great material that can be reused and can create a closed loop system if recycled properly.The infographic above shows the lifecycle of an aluminum can from beginning to end.

In a nutshell the process of recycling an aluminum can goes as follows:

  1. The consumer throws aluminium cans and foil into a recycle bin.
  2. The aluminium is then collected and taken to a treatment plant.
  3. In the treatment plant the aluminium is sorted and cleaned ready for reprocessing.
  4. It then goes through a re-melt process and turns into molten aluminium, this removes the coatings and inks that may be present on the aluminium.
  5. The aluminium is then made into large blocks called ingots. Each ingot contains about 1.6 million drinks cans.
  6. The ingots are sent to mills where they are rolled out, this gives the aluminium greater flexibility and strength.
  7. This is then made into aluminium products such as cans, chocolate wrapping and ready meal packaging.
  8. In as little as 6 weeks, the recycled aluminium products are then sent back to the shops ready to be used again.

Some Facts About Aluminum Recycling:

  • It saves 95% of the energy compared to making aluminium from its raw materials (known as primary production).
  • It saves 95% of the greenhouse gas emissions compared to the primary, or smelting, process.
  • It saves raw materials. It reduces the space needed for landfill – where waste is buried in holes in the ground.

If you are a consumer of aluminum cans in your day to day life, please recycle the can or save it to recycle later if there aren’t any recycling locations nearby. It makes a great difference in how we continually use our resources from nature.
