7.67 million tons or 3.3% of MSW by weight.*

56.25 pounds of office paper per person.*

9.31 million tons in 2000 (industry data).

25% of office papers are generated in homes and 75% are generated in businesses.*

32.7 million tons of printing and writing paper in 2000 (industry data).

234 pounds of printing and writing paper per person in 2000 (industry data).

Recycled:

4.04 million tons for a 52.7% recycling rate.*

4.37 million tons for a 46.9% recovery rate in 2000 (industry data).

13.4 million tons of printing and writing paper for a 41.1% recovery rate in 2000.

Office paper is the most heavily recovered segment of printing and writing paper.

Recycled Content:

Office paper can range from 0% to 100% recycled content, depending on a paper mill's ability to use recycled office paper as a raw material. Laboratory tests show that recycled copier paper meets the same quality standards as virgin copier paper.

Composted:

Office paper is compostable if shredded properly. A low nitrogen content and lack of physical structure are inhibiting factors.

Incinerated or Landfilled:

3.63 million tons or 2.2% of discarded MSW by weight.*

Office paper is easily combustible with a per pound Btu value of 7,200, compared with 4,500 Btu to 5,000 Btus for a pound of MSW.

Landfill Volume:

8.67 million cubic yards or 2.1% of landfilled MSW in 1997.

Density:

Landfilled office paper weighs 800 pounds per cubic yard.*

Unbaled office paper has a density of 375 pounds to 465 pounds per cubic yard.

Unbaled computer printout paper has a density of 655 pounds per cubic yard.

Baled office paper has a density of 700 pounds to 750 pounds per cubic yard.

Baled computer printout paper has a density of 1,310 pounds per cubic yard.

Source Reduction:

Double-sided copying, use of the lightest basis weight stock possible for a job, e-mail and extensive use of online systems will reduce office paper usage.

Recycling Markets:

The primary markets for recycled office paper are mills that make tissue paper, printing and writing paper, or paperboard packaging. Export markets also are important but are subject to major fluctuations depending on the strength of Asian economies. Ten years ago, more than half of recovered office paper was exported, primarily to paper mills in Pacific Rim countries.

End-Market Specifications:

Office paper consists of many different types of paper, resulting in a wide range of paperstock specifications. The Institute of Scrap Recycling (ISRI) guidelines for Paperstock PS-01 include specifications for computer printout (#42); sorted white ledger (#40); sorted colored ledger (#38); sorted office paper (#37) mixed paper (#2); and soft mixed paper (#1).

The array of paperstock grades forces office paper programs to collect a limited number of separate high-value grades, such as computer printout or white ledger or a lower-value mixed-paper grade in which fiber types and colors are mixed together.

High-value end-markets exclude or strictly limit groundwood fibers, laser printing, colored paper, nonwater soluble glues and nonpaper items such as paper clips and rubber bands normally found in office waste. Individual mills have their own mill-specific office waste paper grades. Consequently, recyclers must consult carefully with purchasers about specifications before delivering office paper to a market.
