STADLER completes groundbreaking lightweight packaging sorting plant for PreZero in Sollenau, Austria

STADLER Anlagenbau GmbH delivers one of Europe’s most advanced automated recycling facilities, combining high-performance technology, cutting-edge AI integration and sustainable design to support circular economy goals in Austria.

STADLER, the globally active German company specialised in the planning, production, and assembly of turnkey sorting plants, has completed and commissioned a groundbreaking lightweight packaging (LVP) sorting facility for PreZero Sorting Austria GmbH in Sollenau. The plant represents a major advance in automation, safety, and performance – and stands as the most complex and largest facility STADLER has built to date.

For PreZero, the international environmental service provider of the Schwarz Group, the Sollenau project is a strategic investment aimed at strengthening Austria’s regional recycling infrastructure. Its location was selected to fill a geographic gap, enabling shorter transport routes, reduced emissions, and more efficient waste management. Designed to process 104,500 tonnes annually across two modules, the facility combines innovation and scalability to help Austria achieve its sustainability ambitions.

Tackling the challenge with innovation and precision

The project’s delivery required technical expertise and precise coordination across multiple teams and phases. With many trades working simultaneously and installation beginning before the construction of the halls was complete, the complexity of execution was unusually high. STADLER’s ability to navigate these conditions was crucial to delivering the turnkey facility on schedule, with commissioning finalised by late summer 2025.

“This project was undertaken under a very tight schedule and required continuous coordination with all involved trades working in parallel,” said Benny Kalmbach, Project Manager at STADLER. “Despite the logistical challenges, we delivered a complex, high-performance facility on time through close collaboration with PreZero, STEINERT, and all on-site partners.”

PreZero also emphasized STADLER’s strong partnership approach and technical expertise throughout the process, as Marya Brandt, Project Manager at PreZero, pointed out: “STADLER successfully overcame challenges like integrating the AI-based fire protection system, ensuring high automation, and meeting strict safety and environmental standards. Their tailored approach enabled the smooth implementation of a complex, future-ready facility.”
