A Gripper in the Spotlight: Technology Playing a Key Role in the Energy Transition

In a recent article on ntv (source: ntv.de) about thermal waste-to-energy processes, one thing stands out unmistakably: a KRÖGER gripper, a METZEN product brand, in operation at a waste incineration plant. A single image, yet full of symbolic significance. It highlights that the energy transition is driven not only by wind turbines and solar panels, but also by technologies working behind the scenes—where processes may appear invisible, yet are fundamentally important.

Thermal waste treatment has long been underestimated in public debate. Many still regard it merely as a disposal technology, whereas it has in fact become a cornerstone of sustainable energy supply. Today, waste incineration plants provide climate-friendly heat and electricity to hundreds of thousands of households, ensure the disposal of residual and commercial waste, and reduce dependence on fossil fuels. At this complex interface between waste management and energy production, reliability is key—and this is precisely where KRÖGER gripper solutions make a difference.

A gripper faces enormous challenges every day: extreme temperatures, abrasive materials, dust, and difficult-to-access operating areas. That it handles these tasks seemingly effortlessly is no accident; it is the result of a design fully focused on durability, robustness, and cost-efficiency. Every hour of operation without downtime not only ensures process efficiency but also contributes to the stability of energy supply.

For METZEN, the energy transition does not stop at thermal waste treatment. Our team supports many customers along other crucial pathways. With innovative conveying technology for sewage sludge, we help make wastewater processes increasingly usable for energy generation. Systems for plastics recycling ensure that valuable raw materials are not lost, but returned to the cycle—a similarly essential component for resource conservation and climate protection.

The KRÖGER gripper thus symbolises an approach: the energy transition means striving for efficiency, safety, and sustainability at every link in the chain. Whether in waste-to-energy plants, sewage sludge treatment, or recycling, it is the technologies behind the scenes that make major societal change possible.
