UPGRADING OF PLASTICS
We print on 100% recycled paper.TITECH’s innovations are helping to produce it.
APPROACH TO MODERN PLASTICS SORTING
In order to produce new plastic food-
grade packaging from recycled poly-
mers such as PET bottles it is necessary
to achieve very high and consistent
quality standards. Until very recently
recycling facilities opted instead for
making a lower grade recycled polymer
to be used in other products such as
then lost as a raw material for the
food-grade packaging production loop.
Using innovative systems TITECH
enables you to produce a high quality
food-grade recycled polymer and thus
close the loop in the recycling process.
For example bottle-to-bottle
Less than 100 ppm impurities – this
means almost perfect purity. This re-
into new transparent bottles. Even
the smallest impurity prevents their
use in bottle-to-bottle procedures.
In order to sort out any residue of or-
ganic matter, metals, PVC or coloured
particles of just 2–12 millimetres must
-
est reliability for colour and material.
Standard technology did not achieve
all in once.
Technology
we transformed the proven TITECH
autosort into an innovative specialist
– tried and tested technology meets
highly developed double-sensor
systems. (VIS) provided colour infor-
mation, (NIR) information from the
near infrared range.
Only these two dimensions combined
allow for simultaneous and reliable
detection of colour and material type.
The short distance between measure-
ment process and discharge as well as
a particularly tight valve grid ensure
positive material separation.

Step 1 Pre-treatment
plastics contains both bottles and
foil. In an upstream process, a
„ballistic separator“ separates these
two- and three-dimensional objects.
Optionally you can integrate a
TITECH autosort which provides
continuous quality of the manually
or automatically pre-sorted material.
Step 2 3 Step Sorting
The pre-sorted plastics pass a multi-
step sorting process in which NIR and
VIS sensors detect colour and materi-
al. Depending on the degree of soiling
and on plastic type, foreign materials,
non-ferrous metals and wrong colours
are ejected. This results in a mono

PP, ferrous and non-ferrous metals…).

Step 3 Flake Sorting
These recovered single-coloured
grain size fractions of 2–4 and > 4 to
then detects material and colour of
thus again ejecting impurities and
wrong colours. The result is a PET
and very low material loss (< 100
ppm) – the standard for bottle-to-
bottle is thus achieved. But the
ejected fraction is no waste either –
in the double-step process it passes
be recovered.
Step 4 Flake Quality Control
Better safe than sorry: At the end
of the process, an NIR sensor
detects and impurities and thus
checks permanently for constant
quality. Without that, long-term
application in industrial production
would not be feasible.

Maintenance
Especially with the high throughput
downtime due to machine mainte-
nance causes high losses. Therefore,
vital machine parts such as lamp and
nozzle bar are designed to be serviced
in running operation.
The level of the scanner’s performance
and the purity level of the sorted
material depend on the intensity of
the light. When dust and dirt from
the conveyor belt is deposited on
the lamps, the strength of the light
is affected considerably.
The TITECH lamp units are particularly
easy to clean and maintain. A glass
front protects the individual lamps, the
and the lamp units are mounted with
wing nuts. This way they can be
replaced and aligned quickly and
without any problem.
Maintenance in running operation
is also possible for the nozzle bars
which can be soiled by moisture
from the cleaning process. They are
easily accessible so that cleaning
does not require to stop the entire
sorting process.
