  • K2022 duo 900

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.

Digital product passport enables traceability


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.

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!
