Due to its great use in the packaging industry, plastics represent one of the main components of solid wastes. Plastics are not biodegradable (with some exceptions) and it is therefore extremely important to increase the recycling activities. Advantages given by plastics recycling are mainly:
1. waste reduction
2. cost decrease of the final product
3. energy consumption reduction
4 environmental protection, due to emissions reduction
5. oil saving.
Starting from a waste/scraps (PET, PVC, HDPE. LDPE, PS, PA and ABS are the most commonly recycled plastics), through plastics recycling it is possible to obtain a new end-product with high technical features.
A correct process design and extrusion technology are key factors to grant quality products and investment returns.
In the plastic recycling industry a innovation element is the use of co-rotating extruders that is becoming more and more a winning solution compared to traditional technologies (such as single-screw extruders) in facing most of the issues and challenges that plastic processors have to address today.
Icma San Giorgio has developed advanced recycling systems based on co-rotating extruders dedicated to the recovery of single polymers (HDPE, PA, PET etc.), miscellaneous post-consumer materials (mixed plastics) highly contaminated plastic industrial waste general scraps (eg. tyre rubber). Taking most of their technical features from its MCM – “high torque” family, these specially designed extruders use a particular degassing and filtering systems able to treat demanding scrap materials so that current demand coming from many processors can be matched at the highest quality standard.
