EREMA and Lindner delivers consistent quality in post-consumer recycling
At IFAT in Munich, EREMA Group and Lindner Washtech jointly presented the initial result of their joint venture in terms of digitalization and intelligent energy management in plastics recycling.

In the joint venture, EREMA combines its expertise and experience in extruders and filtration solutions for plastics recycling with Lindner Washtech’s expert know-how in shredding, sorting and washing plastic feed materials.
Data transfer ensures more efficient recycling processes
Standardizing the process control system is an important aspect in plastic recycling. The two partners developed a platform that allows data to be exchanged between the extruder and the washing system, enabling more precise data analysis and effective improvement measures.
All key parameters are taken into account and monitored via a digital interface. For example, it is possible to use information relating to the current throughput of the EREMA Pre Conditioning Unit to optimize the washing process so that it can compensate for fluctuations in capacity and achieve a significant increase in output.
Smart energy management for high efficiency
Coordinating the recycling process steps has already achieved initial success in energy management, which is heat recovery.
The partners use latent heat generated during the extrusion process as an energy source for the washing and drying process. This enables sustainable reduction in carbon emissions and energy costs.
Collaboration along the value chain
To improve the end product and increase the overall efficiency of recycling process at the same time, companies have to work together along the value chain.
EREMA and Lindner work on the recycling loop of HDPE starting material, which is processed into high-quality, food-safe rHDPE pellets using the partners’ technologies. Lindner Washtech and EREMA continue to work intensively together to develop strategies for upcycling plastics and increase recycling rates.
