2 Founded in 1983 EREMA - The Company Each year more than 200 recycling Extruders for different materials Turnover 2002/ ,000,000.- Euro with 240 employees More than 50 patents Largest supplier for recycling extruder

3 Quality Innovation Know-how and technology Market Leader Strong Customer Service EREMA is known world-wide wide for:

4 Historic methods... Material jamming input zone High screw speed needed... Pre-Aglutinator necessary High degradation, low output many sensible components High power consumption (drives, gearboxes, pipework... Cold feeding Material under heat and oxygen influence External compactor (Aglutinator) necessary. And / or Grinders

7 The patented EREMA TVE system Additives CaCO3 cutter compactor cutting & feeding drying densifying homog enising COMPOUNDING! plastics scrap double vacuum venting A start-stop control main drives cutting tools extruder automatic RTF meltfilter pelletising system

8 High performance Compounding-Recycling? Addition of Reinforcing Fillers? EREMA Direct Dosing System

9 COAX From EREMA

11 PLASTIC RECYCLING SYSTEMS VACUREMA Vacuum pre-dryer / extruder combination

12 EREMA RGA - TE - VSV conveyor screw Vacuum lock Vacuum cutter compactor/ drier Double venting Screen changer Vakuum slide Extruder Extruder intake Rotating tools

14 EREMA Melt Filters Auto Backflush Sequence... How it works?

15 EREMA Melt Filters... Symetrical Piston Design Pressure balance

16 EREMA Melt Filters Auto Backflush Sequence... Piston 1 and 2 in production position all 4 screen packs in active filtration position 2 melt inlet II I 1 melt outlet main melt flow

17 EREMA Melt Filters Auto Backflush Sequence... Cleaning of screen pack piston 1 in backflush position 1 I in piston 1 2 II I 1 main melt flow backflush melt flow

18 EREMA Melt Filters... Finished Auto Backflush Sequence Piston 1 and 2 in production position all 4 screen packs in active filtration position 2 melt inlet II I 1 melt outlet main melt flow

19 EREMA Melt Filters Auto Backflush Sequence... Cleaning of screen pack II piston 1 in backflush position 2 in piston 1 2 backflush melt flow II I 1 main melt flow

20 EREMA Melt Filters backflushes between Screenchange Piston 1 and 2 in production position all 4 screen packs in active filtration position 2 melt inlet II I 1 melt outlet main melt flow

24 Operation Condition Upper limits of contamination (The maximum amount could be less in case of combination of different impurities) max. 5% of paper max. 1,5% - 2% of aluminium max. 1% - 2% of copper wire Polymer types PP, LD, LLD, HD, PVC (individual check necessary) PET (individual check necessary)

26 Contamination Example

27 Not only pelletising why not make a product direct from recyclate! Flat sheet for different packaging Direct extrusion of fibres up to 5000 lb/hr Direct blown film production Core extrusion lines PET / PE compounds for different end products ie pallets, display trays, boxes and containers...

crystallization Energy saving, low Production cost Higher

28 EREMA In-line Process for production PET sheet and PET fibre No second degradation No external pre drying and crystallization Energy saving, low Production cost Higher value product Food contact compatibility Also for virgin material

29 EREMA PET In-line Sheet

30 Injection/compression moulding system making large moulded products direct from recyclate Accumulator / Injector Cutter / compactor Extruder with dosing Press section

31 One way, stackable PET Pallets manufactured from coloured PET bottle flake
