Krones Recycling at K 2025 – Closing the plastics loop together

The new, more compact configuration of the washing module offers a resource-saving recycling process, generates even fewer fine particles, and is made from the usual high-quality stainless steel. The machine also offers a wide range for plastic types: The Compact module is suitable for processing PET bottles and trays as well as HDPE, PP, and PS. Thanks to the consistently high quality of washing, it can be also used for bottle-to-bottle processes without any problems. And all this with much less required space.

Especially in demanding recycling concepts where maximum operational reliability is key, the washing module MetaPure Performance has proven its worth thanks to its robust reaction to potential standstills. The established technology based on the previous standard offers maximum reliability and thus remains an indispensable part of the Krones Recycling portfolio. Thanks to targeted optimisations, however, this configuration now works even more efficiently – with consistently low fine particle production and excellent washing results.

The recycling of PET trays has long been considered a technical challenge due to their complex composition, the brittleness of the material, and the high level of contamination. Despite these hurdles, we have succeeded in closing the loop with our technology here too: Used trays are processed into high-quality recyclate that can be used to manufacture new trays. 

Conventional recycling plants for LDPE films, on the other hand, reach their limits when it comes to the washing quality required for reuse. Our technology now presents a solution: Through the targeted use of hot washing and treatment with caustic, we achieve significantly better cleaning performance. The result: High-quality recyclates for demanding film applications and a closed loop for LDPE.
