2Plastics
The word plastic comes from the Greek word
plastikos, meaning "able to be molded."
Thermoplastic is a material that is plastic
or deformable, melts to a liquid state when
heated. It can be melted and reformed numerous
times. Thermosetting plastics (thermosets)
are polymer materials that cure, through the
addition of energy, to a stronger form. The
curing process transforms the resin into a
plastic or rubber by a cross-linking process. A
thermoset plastic cannot be melted and reformed.
3Resin Identification Numbers
In April 2000 we received an e-mail from a site
visitor "I was picking up pop and beer bottles
along the highways of southeast Indiana in 1968
and the bottles had a 2 deposit on them before
that." Another source gives the date of the first
"bottle law" was enacted in Oregon in 1972.

8Did you know????
- The energy saved by recycling one soda bottle
will - Power a 100 watt light bulb for almost an hour
- Power a computer for 25 minutes
- Power a color TV for 20 minutes
- Power a washing machine for 10 minutes
9Plastic Facts
- Over 6.5 billion pounds of plastic were produced
in 2006 - Over 16 million tons of plastic waste is
generated annually in the U.S. and about 2.2 of
all plastics is currently recycled. - It takes about 450 years just for one plastic
bottle to break down in the ground!
10Interesting Recycling Facts
- The United States makes enough plastic film each
year to shrink-wrap the state of Texas. - If you lined up all the polystyrene foam cups
made in just one day, they would circle the
earth. - Plastic bags and other plastic garbage thrown
into the ocean kills as many as 1,000,000 sea
creatures every year ! - Americans use 4 million plastic bottles every
hour! -- Yet only 1 bottle out of 4 is recycled
11Interesting Recycling Facts
- About 1,200 soft drink and salad dressing
containers could carpet the average living room. - Each year American throw away
- 25 billion Styrofoam cups, enough every year
to circle the earth 436 times. - In 1988 we used 2 billion pounds of HDPE just to
make bottles for household products. Thats about
the weight of 90,000 Honda Civics.

19Disposable Diaper Recycling
The Knowaste Process
1. The process begins with shredding the
incoming materials which breaks apart the
diapers. Once the incoming materials are
shredded, they are sent to a pulper. 2. The
pulping action opens up the diapers. This begins
the process of separating the components and
exposes them for chemical treatment. Sanitizing
occurs at the pulper. The plastic is removed by
finger conveyors and is sent to trommels. 3.
The plastics are processed in trommels, where
residual fibers and waste are removed by washing.
Then the plastics are then pressed and pelletized
for sale to the market.
204. The pulp stream goes to coarse screening to
further remove plastics which are also sent to
the trommel. This stream is chemically treated to
deactivate the SAP to make it possible to
separate it from the fiber. 5. The deactivated
SAP, along with residual small plastics, is
separated from the fiber through a cleaning
process. The deactivated SAP can be collected and
reactivated for reuse. 6. The fibers are then
put through a fine mechanical washing, cleaning
and screening process. This produces a clean,
marketable fiber. The reject material is sent to
a sludge press.
217. The clean fiber is then pressed, baled and
sold into the market. These fibers are of
excellent quality as they contain very high
quantity of Softwood Kraft. 8. The water
extracted in the washing and thickening steps is
sent to internal treatment using a dissolved air
clarifier and recycled in the system as dilution
water. 9. The sludge from the clarifier, as
well as the fine screening and cleaning rejects,
are thickened and sent to composting, for which
they are well-suited and break down readily.
