Zellinger GmbH, a specialist in waste disposal and recycling based in Upper Austria, put its first fully electric trucks into operation in May 2025. This makes the company one of the industry’s pioneers when it comes to e-mobility in heavy goods transport. While others are still hesitating, the company is already driving emission-free – and with enthusiasm.

The family-owned company from Walding has been active in waste management, transport, and excavation for over four generations—and has been a loyal STUMMER customer, driven by heart, mind, and a strong sense of sustainability, since the 1980s. Today, nearly 30 STUMMER compactor bodies are in operation at Zellinger, including 17 of the iconic X4 models—true benchmarks in modern waste disposal.

Now, with the delivery of four brand-new STUMMER vehicles, Zellinger is taking another decisive step toward zero-emission waste collection. The future doesn’t roar—it hums quietly.
“Electrifying our fleet is a logical step toward decarbonization,” says Managing Director Jürgen Humer-Zellinger. “We’re not just looking to meet legal standards; we want to take real responsibility—both ecologically and economically.”

All-Electric Powerhouses
The new fleet includes four Medium X4 bodies with ZK 2322 lifters, mounted on fully electric Mercedes-Benz eActros chassis. Three are robust 3-axle trucks, while one is a compact 2-axle version—a perfect balance of power and maneuverability. The difference? Just the volume of the 2-axle truck. The body and lifter remain identical across all four—STUMMER quality, through and through.

With over 130 employees, this long-established company now boasts what is likely the greenest fleet in Upper Austria. In fact, Zellinger currently operates the region’s largest electric-powered fleet featuring the X4/Delta automatic system—a powerful statement for sustainable waste management.

Powering the Future—Independently

One more unique aspect: Zellinger’s electric vehicles don’t rely on just any power source—they run on 100% self-generated electricity. Zellinger is the first and, so far, only waste disposal company in Upper Austria to power its electric fleet using energy derived from its own biogenic waste. At its in-house biogas plant, organic waste is converted into electricity, heat, and liquid fertilizer for agricultural use.

The new e-trucks are primarily used for municipal collection routes and offer a range of up to 300 kilometers per charge. They also meet the highest safety standards currently available, equipped with state-of-the-art assistance systems, including turning assistants to protect pedestrians and cyclists, emergency braking systems, and rear-view cameras.

“Introducing e-trucks is part of our comprehensive sustainability strategy,” explains Jürgen Humer-Zellinger. “We’re already focusing on smart waste management, digital route planning, and energy-efficient operations. Looking ahead, we’re also exploring additional alternative drivetrains such as HVO100 and hydrogen.”

More Than Just Machines: A Shared Vision

STUMMER and Zellinger share a partnership that spans more than four decades—a relationship built not only on horsepower and payload but also on shared values: quality, innovation, and a forward-thinking approach to waste management. It’s this spirit of collaboration that continues to drive both companies toward a cleaner, more sustainable future.
