There are five basic paper grade categories.
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.
There are no recycling mills in Singapore at the moment. Therefore all the paper we collect are packed and sent overseas for the recycling process.
- Old Corrugated Containers – Used carton or cardboard boxes.
- Mixed Paper – Paper that includes things like mail, catalogs, phone books and magazines.
- Old Newspapers – Mills use newspapers, a lower grade paper, to make more newsprint, tissue and other products.
- High Grade Deinked Paper – Office/copy paper that has ink removed.
- Pulp Substitutes – This paper is usually discarded scraps from mills.
- Step 1: After the paper is collected, it’s taken to a factory where contaminants such as plastic, glass or trash are removed.
- Step 2: Next, the paper is sorted into different grades.
- Step 3: Once paper is sorted, it will be stored in bales to be shipped.
- Step 4: Once at the mill large machines (pulpers) shred the paper into small pieces. This mixture of paper, water, and chemicals is heated and the pieces of paper break down into fibers.
- Step 5: The mixture is pressed through a screen to remove adhesives and other remaining contaminants.
- Step 6: Next, the paper will be spun in a cone-shaped cylinder to clean it, and sometimes ink will also be removed. At this point, the pulp is sent through a machine that sprays it onto a conveyor belt. Water will drip through the belt’s screen, and the paper fibers will start bonding together.
- Step 7: Heated metal rollers will dry the paper, and the paper will be put onto large rolls, which can be made into new paper products.
