Mechanical recycling has benefits over chemical recycling, but both will be required for a successful circular plastics economy, according to the CEO of Austria’s polyolefins and fertilizers major Borealis.

Alfred Stern said lower processing temperature, less complexity and more developed infrastructure make mechanical recycling the first choice for Borealis, though limits on its use mean that chemical recycling will be required to further boost recycling rates.
Speaking on the sidelines of the K-Fair in Germany, Stern said that Borealis has chosen to focus initially on mechanical recycling because the technology is already available and has a lot of development potential to further increase quality and yields.
Unit Mold Control available for the KHS InnoPET Blomax series
Automatic control and adaptation of individual stretch blow mold stations
Improved bottle quality and stability with a high recyclate content
Hamburg – Even on the most advanced machine there can be discrepancies in the distribution of PET bottle material in the stretch blow molding process. This has an impact on the bottle quality and production efficiency. In order to optimize these parameters KHS recently developed Unit Mold Control in cooperation with US company Agr International inc. (Agr).
While plastic, which is polluting the seas, may take 1,000 years to decompose, the production of aluminium creates far more carbon dioxide, so cans are problematic, too, says Eric Onstad
GLOBAL bottled water giants are ramping up trials of easily recyclable aluminium cans to replace plastic, which pollutes the world’s seas. But though aluminium cans might indeed mean less ocean waste, they come with their own eco-price: The production of each can pumps about twice as much carbon into the atmosphere as each plastic bottle.
Breakthrough technology being developed to return difficult-to-recycle polypropylene to near-virgin quality now is showing promise for at least one other key resin.
PureCycle Technologies Inc. is developing a commercial-scale PP recycling facility in Ironton, Ohio.
The plant initially is targeting colored and dirty PP. But CEO Mike Otworth said the technology could also handle polyethylene.
According to Erema, the new Vacunite technology offers efficient decontamination, best colour values, top IV stability and low energy consumption.
This is made possible by the combination of Vacurema technology and vacuum-assisted Solid State Polycondensation (SSP) to create a process in which all thermal process steps are performed in a nitrogen and/or vacuum atmosphere.
The Vacunite process is based on the combination of Vacurema technology – which has been proven over the past 20 years and has been further developed for this application – together with newly patented vacuum-assisted Solid State Polycondensation (SSP), which Polymetrix developed for Erema for this application.
Center houses seven high-tech lines for the development of blown film, cast film, polishing sheet and nonwoven products
Reifenhäuser has completed construction work and installation work to fully modernize the largest research and development center for plastics extrusion technology. Inhouse and customer applications are further developed under real production conditions using the latest plastics extrusion technology and extensive know-how.
The center houses seven high-tech lines at the latest state of the art for the development of blown film, cast film, polishing sheet and nonwoven products. The new conference rooms directly adjacent provide a pleasant atmosphere for visitors and customers to view the test lines at close quarters.
Borealis and Borouge have developed a series of new, monomaterial pouch solutions based on polyethylene (PE) and polypropylene (PP).
Designed specifically for recycling, and in collaboration with value-chain partners, these new pouch solutions are described as being suitable for the most demanding consumer packaging applications. In line with the EverMinds™ approach to Thinking Circular, these solutions further expand the range of more sustainable options available to the flexible packaging industry.
