Turning metal wires from pulp bales
into profit with TANA Shark
Metal wires from paper pulp bales are high in value but very hard to shred and clean for
selling purposes. Usually the metal wires are stuck with plastics and some remains of the
pulping process. This particular type of waste is almost impossible to separate, says a
landfill operator in France.
Normally the only possibility to handle
this type of waste is to dump it at a
landfill. This is due to lack of process
and suitable technology to shred and
separate the metal wires from the
plastics and paper pulp residues. To
solve this problem, they decided to do
a trial with the TANA Shark 440. Thrilling results were obtained.
- The TANA Shark 440 proved out to
be a perfect solution for us. For the
first time ever, we have the possibility
to turn annually 10 000 tons of waste
into 750 000 € of profits, says the
operations manager of the landfill in

Success Stories / TANA Shark 440D
How is this possible?
The key to success is the separation
of the metal wires from the plastics in
an optimized shredding process. The
waste consists roughly 50% of metal
wires and 50% of SRF based plastics
and pulp residues. The metal wires can
be sold for >150 € / tons and the SRF
can be burned. The total amount of
10 000 tons can be recycled annually
with the TANA Shark 440. See the table
below for the details of the process.
Because of the possibility to
switch, change or remove counter
knives and use screens of different
mesh sizes, TANA Shark can produce
very homogeneous particle size from
50 to 500 mm. This allows the finetuning of the process for reaching optimal results in the shredding speed
and quality. The client also found intriguing that they can use TANA Shark
for other types of waste as well, such
as wood, plastic and tyres.
Comments from the
”We are able for the first time ever to turn
this type of waste into scrap metal with
resale value. This creates new business
opportunities for us.”

Additional information
1. The waste with long metal wires and
plastics are cut and shred into small
TANA Shark has the ability to cut through
the waste – not to tear it. This reduces
downtime caused by the metal wires and
plastics wrapping around the rotor, which
does not happen with TANA Shark.
2. Metal wires heats up when shred
The heat helps to dry up the wet pulp
and to remove the pulp residues from the
3. Metal, plastic and pulp are separated
Achieved from the conveyor with a
magnet and an air blowing or suction
End results:
> Very clean recycled scrap metal, particle size below 110mm, ready for selling
> Clean plastic and pulp residues are ready to be used for burning purposes
10 000 tons of waste sent
straight to the landfill.

SRF = Solid Recovered Fuel.
The 10 000 tons of annual recycling
capacity of this type is roughly 3040% of the TANA Shark’s total capacity. This means the client can utilize
the TANA Shark 440 for other purposes and materials if needed. This also
opens the possibility to accept more
of this kind of waste for increasing the
profit margin ever further.
– We are very interested in opening new opportunities for business
with TANA Shark, especially when we
have the possibility to shred other materials with the same machine, the operations manager says.
