Enabling a
ZERO-WASTE society

Advanced plant solutions
for plastic recycling and green materials
The co-rotating technology delivered by ICMA secures UP-CYCLING results especially when:
  • There is a need to process materials that are hardly recyclable with traditional technologies
  • You want to create a material with higher specification to replace virgin materials in technical applications
  • You need a very high production capacity. In these cases, it becomes more and more frequently the case of companies normally using single-screw extruders to replace them with specially designed co-rotating extruders.
More:
  • Another advantage is energy efficiency gained by using co-rotating extruders. 
  • The co-rotating technology has the unique opportunity to ADD fillers or reinforcements to the recyclate thus securing  a much larger and profitable market opportunity.
  • ICMA also offers various tech solutions, also patented, for efficient odor removal to get high quality recycling
Depending on the type of tasks required different lay-out can be designed. More details by clicking the following botton.

Recycling of Rigid Polyolefin
HDPE - PP:

ORIGIN: Post consumer liquid container bottles (milk, juice) jars   (detergent) food trays , industrial bins, car fuel tanks

PRE- PROCES: Generally, come from a separation and washing system

PROCES TASK: 

  • Mix the polymers with different viscosity
  • Keep the polymer mechanical characteristics without degradation
  • Perfect degassing for good post processing (injection moulding
  • Fine filtration

REMARKS: Is an high bulk density material, easier to feed

TURN KEY LINE: 

  • Flakes and additive handling
  • Loss in weight gravimetric system
  • High torque co-rotating extruder
  • Continuous screen changer ( no firm links with suppliers)
  • Water ring or underwater pelletizing system
  • Final material handling and packing (big bags)

Proven screw geometry perfect melting/dispersion  of very low MFI fraction

  • Lower residence time under controlled shear & thermal conditions
  • Multiple high efficient degassing ports
  • Double filtration system

ICMA's line FOR ALL PROCESSING TASK:

  • Line including MCM 140 HT   capacity up to 4,5 t/h
  • Line including MCM 110 HT   capacity up to 2,5 t/h
  • Line including MCM 90 HT   capacity up to 1 t/h

Recycling of film

In Film recycling ICMA has addressed some major issues one of which is the feeding of the extremely light film materials. Such compelling task is achieved by a patented system that allows to continuously feed the extruders by also granting a high production yield.

Another advantage of our "one-step" approach is also to avoid expensive and "energy hungry" boiler units upstream frequently proposed by other suppliers.

Recycling with cascade design

In very specific cases cascade design is advisable, for instance, when a very tight filtering process is required before the compounding stage can be started.

Here we recommend to design the line using  2 co-rotating extruders, the first to execute the efficient degassing and filtering tasks and he second for compounding . An upstream single extruder may also be considered although the overall performance level will be affected.

Other material recycling

Several other materials are nowadays finding a new life with our co-rotating extruders. The more common are plastic parts of electrical devices (RAEE) or PET, ABS etc etc .

Just enquire ICMA and come to our Innovation Hub to test your scrap!

Biopolymer

With several lines turn-key or just extruders designed to process bio polymers, ICMA can be the partner of choice to supply a reliable system. Starting in our Innovation Hub with trials to check processability of your formulation.

Natural fibre composites

Our knowledge in mixing natural fibres and a polyolefin roots back to the early 70’s when ICMA successfully pioneered, first in the World, the process technology for producing a thermoformable sheet for automotive interior trims made of virgin or recycled polypropylene and wood flour.

Today are available compounding and extrusion solutions.

Water-soluble Polymer - PVOH

Water-soluble polymers are also a new frontier in our market with the co-rotating extruders delivering best in class results compared to other technology, for instance by avoiding pre-mix in the material preparation and enabling "one step" process task.

Extrusion

The direct extrusion of sheets made of recycled resins allows the value increasing of a “poor” product.

The use of a corotating extruder allows the feeding of recycled scraps with a low selecting level, therefore cheaper.

From industrial wastes or selected post consumer scraps it is possible to obtain sheets having good mechanical properties that can be engineered with the addition of mineral fillers or reinforced and possibly further improved with the application of co-extruded aesthetic film.
