How is Paper Recycled? Learn About the Recycling Process at Pratt Industries
Summary
TLDRThe video offers a detailed tour of a material recovery facility, showcasing the process of waste sorting and recycling. Trucks unload waste, which is then sorted by workers and machinery, including a disc screen and a trommel. Materials are separated into various streams and undergo quality checks. Cardboard is baled for transport to a paper mill, where it's recycled into new paper products. The facility plays a crucial role in Pratt Industries' commitment to providing 100% recycled packaging solutions.

Q & A
What is the first step in the material recovery process at the Conyers facility?
-The first step is for trucks to arrive at the facility, where they stop on a scale to be weighed before proceeding to unload the materials onto the floor.
How is dust managed during the initial stages of material handling?
-A mister is used to help manage any dust as the materials are moved onto the first conveyor.
What is the function of the pre-sort line in the facility?
-The pre-sort line is where workers manually remove contaminants from the material, dropping them into bunkers below.
How is cardboard separated from other materials?
-Cardboard is separated from other materials using a disc screen, where it climbs the screen while the remaining material falls through.
What happens to the fines, medium-sized, and large items after the trommel separates them?
-Fines are conveyed past a cross-belt magnet to capture ferrous materials and an eddy current to capture aluminum. Medium-sized materials go to a ballistic sorter, while large items are conveyed to a blower sorter, which separates light and heavy materials.
What is the role of the blower sorter in the facility?
-The blower sorter separates light materials from heavy materials, which are then sent to separate sort lines where contaminants are removed.
How is mixed paper sorted and handled?
-Mixed paper is sorted using optical sorters in the light stream. After passing a final quality control check, it is loaded into a mixed paper truck.
What materials are separated by the optical sorters on the optical sort line?
-The optical sorters on the optical sort line separate number two HDPE (high-density polyethylene), number one PET (polyethylene terephthalate), and cartons.
What happens to the bales of sorted commodities after they are compressed?
-The bales of sorted commodities are stacked and loaded onto trailers to be sold as commodities.
What is unique about the handling of the mixed paper stream?
-The mixed paper stream is hauled directly to the Pratt paper mill, where it is re-pulped and made into 100% recycled paper. The recycled paper is then either converted into new cardboard or shipped to other Pratt facilities.
Outlines
🚚 Material Recovery Facility Operations
The script provides a detailed tour of a material recovery facility, starting with trucks weighing in and unloading materials. A front loader moves materials to an in-feed bunker, where a drum feeder controls the flow onto a conveyor. Dust is managed by a mister. Workers manually remove contaminants from the material on the pre-sort line, and it then proceeds to a disc screen where cardboard is separated. The remaining material is further sorted through a trommel into three streams: fines, medium-sized, and large items. Fines are processed through a cross-belt magnet and eddy current to extract ferrous and aluminum materials. The large items are sorted by a blower sorter into light and heavy materials. The medium-sized materials are sorted by a ballistic sorter into two-dimensional and three-dimensional materials, with optical sorters further separating different types of plastics and cartons. A final cross-belt magnet and eddy current capture any remaining metals. The sorted materials are then baled and sent for further processing or sale.

Highlights
Trucks arrive at the facility and are first weighed on the scale.
Materials are unloaded onto the floor and then scooped by a front loader into the in-feed bunker.
A drum feeder meters materials onto the first conveyor, which is equipped with a mister to manage dust.
The first conveyor leads to a pre-sort line where workers remove contaminants.
Cardboard is separated using a disc screen, which allows it to climb while other materials fall through.
Cardboard undergoes two quality control checks before being manually loaded onto the baler line.
Material passing through the disc screen is directed to a trommel for further separation.
The trommel separates materials into fines, medium, and large items.
Fines are conveyed past a cross-belt magnet and eddy current to capture ferrous and aluminum materials.
Large size materials are sorted by a blower sorter, which separates light from heavy materials.
Both light and heavy material streams undergo final quality control checks.
The heavy side is conveyed to an optical sort line for further separation.
Medium-sized materials are sent to a ballistic sorter to separate two-dimensional from three-dimensional materials.
Two-dimensional materials are processed through an optical sorter to yield mixed paper.
Three-dimensional materials are also sent to the optical sort line for further processing.
The optical sort line uses a crossbelt magnet and eddy current to capture aluminum.
Each commodity is conveyed or blown into a bunker and then loaded onto the baler conveyor.
Bales are stacked and loaded onto trailers for sale as commodities.
Mixed paper is sent directly to the Pratt paper mill for repulping and recycling into 100% recycled paper.
The facility plays a crucial role in Pratt Industries' commitment to providing 100% recycled packaging solutions.

works
trucks arriving at the facility stop
first on the scale to be weighed
then circle the building and unload onto
the floor
a front loader scoops and dumps
materials into the in-feed bunker where
a drum feeder meters it onto the first
conveyor
a mister helps manage any dust
the first conveyor rises to the pre-sort
line where workers remove contaminants
dropping them into bunkers below
[Music]
then the material drops onto the disc
screen cardboard climbs the screen and
the remaining material falls through the
cardboard passes two more quality
control checks and then drops onto the
floor for manual loading onto the baler
line
the material dropping through the disc
screen is conveyed to the trommel the
rotating trommel separates the material
into three streams
fines
medium smaller than 10 inches in
diameter and large items above that size
the fines drop out first and are
conveyed past a cross-belt magnet to
capture ferrous material and an eddy
current to capture aluminum the large
size materials come out the end of the
trommel and are conveyed to a blower
sorter which separates light materials
from heavy the two material streams each
drop onto a sort line where contaminants
are removed the light sort is conveyed
to the mixed paper truck passing one
final quality control check the heavy
side is conveyed to the optical sort
line the medium-sized materials coming
out of the trommel are conveyed to the
ballistic sorter
ballistic sorter separates
two-dimensional materials from
three-dimensional materials
the two-dimensional stream passes
through an optical sorter with the clean
stream yielding mixed paper
the three-dimensional stream is conveyed
to the optical sort line
the combined feed entering the optical
short line first passes under a
crossbelt magnet then
three inline optical sorters separate
number two hdpe
number one pet
and cartons
the stream then passes under a final
cross belt magnet and then an eddy
current to capture aluminum
[Music]
each commodity is conveyed or blown into
a bunker and then fed one at a time onto
the baler conveyor to be compressed into
bales
bales are stacked and then loaded onto
trailers to be sold as commodities
but the mixed paper stream has a special
destination once a mixed paper trailer
is full the feed switches to the empty
trailer the full trailer is then hauled
directly to the pratt paper mill and
unloaded to be re-pulled and made into
100 recycled paper from there the giant
rolls are either converted into new
cardboard at the adjacent manufacturing
plant or shipped to other pratt
facilities throughout the us
this facility is the first step in
enabling pratt industries to provide our
customers with 100 recycled packaging
solutions i hope you enjoyed the tour
[Music]
