Sustainable and resource-efficient
The new ECOFILLER PLUS MK2 is a significant step toward waste-free production.
As a pioneer in sustainable polyurethane technologies, the Hennecke GROUP presents the ECOFILLER PLUS MK2, a consistent further development within its Environmental Technologies product line. The revised and patented version of the ECOFILLER PLUS, which was introduced in 2022, places even greater emphasis on process optimization and resource conservation in the processing of rigid polyurethane foam.
ECOFILLER PLUS MK2 at a glance

Strengthened leading role in the circular economy
The ECOFILLER PLUS MK2 enables precise in-line dosing and extremely homogeneous mixing of liquid and solid components. The focus is on the efficient recycling of shredded cutting residues and production waste in powder form directly back into the production process. “With the ECOFILLER PLUS MK2, we have consistently developed our vision toward waste-free production. This approach not only reduces the consumption of valuable raw materials, but also lowers our customers’ disposal costs in the long term,” explains Gianmario Bossi, Senior Director Global Sales and Service Lamination. The ECOFILLER PLUS MK2 perfectly complements the PANELMASTER STEEL and PANELMASTER FLEX systems and is offered by Hennecke-OMS as an addon for production environments that use PUR and PIR-based raw material systems.
Innovative enhancements for maximum efficiency
The patent granted in October 2024 by the Italian Patent and Trademark Office (UIBM) for the ECOFILLER PLUS MK2 underscores the technological uniqueness of the solution and confirms the Hennecke GROUP’s innovative leadership in the field of sustainable metering technologies. The patent protects key components and processes for returning production waste to the ongoing process – a decisive step towards a circular economy. The suffix “MK2” also stands for significant technological advances in the Hennecke product landscape:
- FOAMATIC machine control as a central upgrade: One of the most significant innovations is the implementation of FOAMATIC, which is used in all Hennecke “next-gen” metering machines. This advanced control system enables significantly improved harmonization of process sequences and offers intuitive operation via a SIMATIC Premium 12-inch HMI.
- Extended areas of application: The ECOFILLER PLUS MK2 is the optimal solution for an even wider range of panel types, and now explicitly supports the production of sandwich panels with rigid facings for use in the construction sector, as well as insulation boards with flexible facings, which are used, for example, for energy insulation of house walls.
- Perfected homogeneity and process control: The technical challenge of ensuring completely consistent homogeneity of solid and liquid components has been further perfected. Recipes and the ratio of polyol to powder can be adjusted at any time during production via the control system. The system significantly reduces mixing time and enables much faster production.
Safety through optimized flame protection
The ECOFILLER PLUS MK2 also plays a central role in improving the flame protection of sandwich panels. The system allows powdered flame retardants to be incorporated into the recipe in a completely homogeneous manner, ensuring that the concentration of solid components is constant throughout the end product. This enables manufacturers to develop and test their own recipes for improving fire behavior and integrate them into their formulations for mass production.
Sustainability as a core competence
With the ECOFILLER PLUS MK2, Hennecke underscores its leading role in environmentally friendly technologies in the field of reactive plastics. The system embodies the company’s goal of moving closer to waste-free production and makes a significant contribution to a more sustainable industry. The Environmental Technologies product line is thus setting new standards in the polyurethane industry and paving the way for a future in which resource conservation and production efficiency are inextricably linked.
With the ECOFILLER PLUS MK2, Hennecke is sending a strong signal for sustainable production in the processing of reactive plastics. The innovative metering machine is exemplary of the company’s goal of achieving increasingly waste-free production – and thus makes an active contribution to a resource- conserving industry. As part of the Environmental Technologies product line, the ECOFILLER PLUS MK2 sets new standards in the polyurethane industry and impressively demonstrates how efficiency and environmental responsibility can be intelligently combined.
