Paper (fiber)Main types of paper:
1.White Office Paper
2.Mixed Paper
3.Newspaper
4.Magazines
5.Corrugated Cardboard
6.Box Board
7.Kraft Paper
8.Molded Pulp
4/17/13 19Sustainability for All & Corps Innovation
PaperWhite Office Paper
Definition: Most white paper that comes from an office that is made from tree pulp and/or recycled paper.
Key Characteristics: • White (bleached) • Long, strong fibers• Typically 8.5” x 11.0” in size
4/17/13 20Sustainability for All & Corps Innovation
PaperNewspaper
Definition: Low-grade “ground-wood” paper that is used for newspapers. Includes all paper inserts. No plastic bags or rubber bands.
Key Characteristics: • Typically grey in color• Short, weak fibers• Ink that comes off easily• Yellows in sunlight (due to
presence of lignin)• Rips vertically, but not
horizontally in a line.
4/17/13 21Sustainability for All & Corps Innovation
PaperMagazines
Definition: Grade of paper that is used for magazines. Paper typically coated with “kaolin” (clay) which is used for pictures.
Key Characteristics: • Typically glossy• Used for magazines with pictures• Short, weak fibers• Can have a wax or chemical
coating to protect images• Bound with staples or glue
4/17/13 22Sustainability for All & Corps Innovation
PaperBox Board
Definition: Grade of paper that is used for light weight boxes.
Key Characteristics: • Typically outside is printed in
color• Inside is brown or grey• Short, weak fibers• Can have glue or “wet-strength”
to make stronger or help keep fibers together in the presence of water.
• Sometimes made from recycled newspapers
4/17/13 23Sustainability for All & Corps Innovation
PaperKraft Paper
Definition: Grade of paper that is made from “ground-wood.”
Key Characteristics: • Thick paper with long, strong
fibers• Typically brown (not bleached) in
color• Most common use is for grocery
store bags or lunch bags• Has some “wet-strength” to make
stronger or help keep fibers together in the presence of water.
4/17/13 24Sustainability for All & Corps Innovation
PaperMolded Pulp
Definition: Very low-grade of paper that is made from “ground-wood” and “molded” into shape
Key Characteristics: • Typically grey or dark in color• Most common use is for egg
cartons or for fruit separators• Contains “wet-strength” to make
stronger or help keep fibers together in the presence of water.
• Often made from recycled newspapers.
4/17/13 25Sustainability for All & Corps Innovation
PaperCorrugated Cardboard
Definition: Paper that is made from “ground-wood” and has three layers (two flat layers with a wavy one in between).
Key Characteristics: • Long, strong fibers.• Typically brown in color.• Most common use is for cardboard
boxes.• Contains “wet-strength” to make
stronger or help keep fibers together in the presence of water.
4/17/13 26Sustainability for All & Corps Innovation
PaperMixed Paper
Definition: Most paper that comes from an office that is made from tree pulp and/or recycled paper.
Key Characteristics: • Any color • Typically includes a variety of
different types of papers– White paper– Newspaper– Magazines– Box board– Kraft Paper
• Similar to Junk Mail
4/17/13 27Sustainability for All & Corps Innovation
Key TermsContaminate
Definition: Anything that makes a material impure or unclean by contact or mixture. In recycling, typically anything that will cause your materials to be downgraded or decreased in value. Usually a material category will allow a certain percentage of contamination.
Example: White paper can have no more than 2% contamination.
4/17/13 28Sustainability for All & Corps Innovation
Key Terms
4/17/13 29
Out Throw
Definition: Anything that is not allowed or unwanted. In recycling, typically anything that will cause your materials to be downgraded to the lowest grade or decreased in value. Material categories will not allow any percentage of out throws.
Example: Container glass is not allowed to have any porcelain or ceramics in the mix.
Sustainability for All & Corps Innovation
Key TermsDowngrade
Definition: Term used to describe a bin of sorted materials that has been reduced in value due to and exceedingly high level of contaminates or the presence of out throws.

Practical ExercisesFlashcards
Exercise: In groups of two people divide the materials flash cards in two stacks. One person holds up the picture of the material and the other person has to:1. Identify the material?
2. Explain how you came up with your answer
3. Note key characteristics of the material
4. What LCC recycling category does it belong in?
Each person takes a turn until all of the flash cards are used.
4/17/13 31Sustainability for All & Corps Innovation
Practical ExercisesGrab Bag
Exercise: Grab one material out of the Materials Identification Demonstration bin and tell the group:1. What is the material?
2. Explain how you came up with your answer
3. Key characteristics of the material
4. What LCC recycling category does it belong in?
4/17/13 32Sustainability for All & Corps Innovation
Practical ExercisesBin Sort
Exercise: In groups of two people remove materials from the bin and group materials by LCC recycling category.
