RECYCLING OF POLYETHYLENE TEREPHTHALATE (ABBREVIATION PET)
The development of the process for PET recycling has been underway for more than 2 years now. In cooperation with the
company LCI, the Amandus Kahl representation in the uSA in the field of chemistry, and a well-known u.S. company, a proc-
ess was developed that allows the production of a granulate from shredded PET bottles which can be directly reused for the
production of PET bottles. Since the newly developed process is very sensitive, it was necessary to adapt the corresponding
machines to the process. The process functions with very short effective bores at relatively high temperatures (about 130 °C);
thus the machines have to be operated with oil cooling and special lubricants as well as with special devices. The development
is based on the pelleting press type 33-390 the data of which was used to design the current production presses type 38-600.
Since the beginning of 2009, two plants have been put into operation,
which achieved the calculated expectations of quality and quantity right from the start.
RESEARCH & DEVELOPMENT AT AMANDUS KAHL
In the highly dynamic environment of a medium-sized company
with a vast field of activities, the classical department of re-
search & development (R&D) has to be open-minded and flex-
ible in order to meet the high demands of our customers with
regard to innovations in process engineering and plant and me-
chanical engineering.
The success in recent years, and in fact for decades, proves that
the company's high investments in the field of R & D and in
the pilot plant have been justified. Our philosophy in research
and development is to advance the well-known main machines
such as flat die pelleting press, expander, belt drier, etc. and
to modify and optimise them for new markets and processes
so that they can be used also in new and yet to be discovered
niche industries.
In the following some examples of the adaptation of such plants
to new industrial sectors:
• Grinding concepts for cereals for the production of bioethanol
• Optimisation of the pelleting presses for wood pelleting
• Shaping of distillers grains (bioethanol)
• Extruder in the semi-luxury items industry
• Pan grinder mill for grinding (article in this Journal)
• Fabric belt drier
• Crown Expander
Other examples of process engineering solutions with optimum
adaptations of the machines:
• Extruder (on the basis of the expander) => fish feed plants
• Pelleting press 1500
• Eco-processor
• Flat die pelleting press in the pharmaceutical sector
• Continuous cooker /vacuum coater
• Waste tyre recycling plants
• Batch mixer for preheating of green coffee

The ideas and developments are the result of the cooperation
of many departments and of the interaction with institutions,
our customers, prospective buyers and associates of our company.
The development is never completed when the first machine
is fabricated or the first process is implemented. These
innovations are always accompanied by the staff of our R & D
department or the pilot plant who assist our customers during
start-up and production.
