Directly processing of recycled material in the 2-stage process
duo 900 – the powerful two platen machine
Dolly pallet made from recycled plastic flakes
With a new, two-stage process, we make it possible to process plastic waste as flakes in injection moulding directly after grinding. Since granulation as a separate process step is no longer necessary, the innovation significantly increases energy and cost efficiency in plastics recycling. At K2022, we will be demonstrating the new two-stage process for the first time with a live exhibit, which can be seen at the ENGEL trade fair stand in the Circular Economy Forum in the open-air area between Halls 11 and 16.

R-Cycle
R-Cycle documents the properties during production and makes this data available to improve the sorting process at the end of the life cycle.
For this pallet, a digital product passport was created in R-Cycle that records relevant information during grinding, granulating and injection moulding.
 "Material Cycle")
Pallet is shredded and returned to the cycle
The pallets that are injected at the K fair are transported to the Lindner booth. Lindner shreds the pallets live at the fair and returns the regrind to ENGEL booth. This cooperation is demonstrated live at the trade fair every day. Together we close the cycle!

CO2 footprint: an opportunity for the plastics industryJune 15, 2022Rising energy and raw material prices see plastics processing companies face new challenges. "Reducing the CO2 footprint even faster gives companies leeway. Competitiveness and resilience are boosted," as Dr. Gerhard Dimmler, CTO of the ENGEL Group, emphasises in the run-up to K 2022. "ENGEL is the role model when it comes to solutions that save CO2 in injection moulding. And that is precisely what we are demonstrating in Düsseldorf this October."
