Sorema presents deinking process for extrusion in recycling plant

Source:Adsale Plastics Network Date :2022-02-25 Editor :JK

Inks and coatings are an integral part of packaging but can represent a serious challenge when trying to enhance materials and to transform packaging waste into a resource.

 

Nowadays, market demand is growing for high quality recycled material coming from post-industrial and post-consumer flexible and rigid packaging waste. This situation has highlighted the need for new recycling plants and processes for the economic removal of printing inks.

 

To facilitate a high quality product, inks must be removed down to a very low level.  Inks that remain in the recycled material can alter the colour and/or the transparency of the material, create defects on the final product and degrade to form odour, gassing or migratable species.

 

The flakes and granules contaminated by ink residues are of great concern in their reuse in new food contact packaging. Once inks are removed then the plastic can potentially be recycled back into its’ original application.

 

Current technologies for the recycling of printed waste rely on processes of thermal degradation of the inks in extrusion with their elimination during the degassing and filtration phase of the melt. As efficient as they may be, these processes are however unable to eliminate a high inks loads. These can remain in the recycled polymers with consequent limitations in the materials reuse in new packaging.

Sorema introduces a deinking process upstream of the extrusion phase used in recycling plant.


Sorema has therefore introduced a deinking process upstream of the extrusion phase, thus obtaining materials with minimal printing ink residues and allowing the subsequent extrusion operation to produce a high quality polymer.

 

Sorema works to offer innovative solutions to its customers, so that they can seize new opportunities with reliable and tested solutions. After a robust development phase, in its R&D department, Sorema is now able to offer the market a wide range of solutions for ink removal.

 

Technologies had already been developed and installed, in the year 2000, but needed to be adjusted and updated to address these new technical demands. The technology remains based upon the proven process of “batch” washing and so ensures a repeatable and defined cleaning of the substrate.

 

The de-inking module is an advanced washing system, developed by Sorema, for the removal of inks and successfully combines several factors.

 

These include the feeding of the incoming material with volumetric or gravimetric dosage, the controlled and independent dosage of chemical additives and a high friction of the material in hot water with a defined residence time adjustable to each specific inks and material. In this way, customers have the opportunity to wash rigid and flexible plastic materials on a single plant.

 

The recycling process is then completed by one or more rinsing and drying phases of the flakes, before an eventual extrusion into granules.
