Packaging sorting plant Spain -STADLER asserts its circular economy leadership with a next-generation packaging sorting plant in Spain via a long-term 25-year partnership with BZB 29-01-2026
Packaging sorting plant Spain
A milestone modernization for waste sorting in the Basque Country
STADLER has successfully completed the full modernization of the BZB lightweight packaging facility in Amorebieta-Extano, Bizkaia, marking a decisive step forward for advanced waste management in northern Spain. The project upgrades the first turnkey plant ever built by STADLER in the country, transforming it into a high-performance packaging sorting plant Spain aligned with current and future recycling demands.
The renewed facility was officially inaugurated on January 27, 2026, in the presence of representatives from BZB, Ecoembes, STADLER, and regional stakeholders. The project significantly increases sorting capacity, improves material purity, and introduces higher levels of automation and digitalization, ensuring long-term operational resilience.
BZB and its role in circular economy development
Bizkaiko Zabor Berziklategia, known as BZB, operates as a public-private partnership between Garbiker, part of the Provincial Council of Bizkaia, and Trienekens País Vasco. For decades, BZB has played a strategic role in the collection, sorting, and recovery of household and commercial packaging waste.
Through continuous innovation, BZB converts discarded materials into valuable secondary raw materials, supporting circular economy objectives across the region. The modernization of its packaging sorting plant Spain strengthens this mission by enabling higher recovery rates and improved material quality, essential for downstream recycling industries.
A partnership spanning nearly 25 years
The significance of this project goes beyond technology. The original BZB facility, commissioned in 2002, was STADLER’s first complete sorting plant in Spain. That project laid the foundation for the company’s long-term presence in the Spanish market and established a relationship built on reliability, performance, and trust.
Nearly a quarter of a century later, BZB once again selected STADLER to redesign and deliver a new-generation packaging sorting plant Spain. This decision reflects confidence in STADLER’s engineering expertise and its ability to adapt complex facilities to evolving regulatory, environmental, and market requirements.
Modernization instead of relocation
Rather than constructing a new facility elsewhere, BZB opted to modernize the existing site in Amorebieta-Extano. This strategic decision maximized the value of existing infrastructure while minimizing land use and environmental impact.
Working within the constraints of the original building required precise engineering and compact equipment layouts. STADLER implemented tailored design solutions that significantly outperform the original installation while maintaining operational continuity. The result is a packaging sorting plant Spain that delivers substantially higher throughput within the same footprint.
Advanced automation and digital integration
The upgraded plant incorporates the latest generation of sorting technologies, combining mechanical separation, optical sorting, and intelligent automation. These systems enhance the accuracy of material separation, reduce contamination levels, and increase overall efficiency.
Digital monitoring tools allow real-time performance tracking, predictive maintenance, and data-driven optimization. This level of digital integration positions the packaging sorting plant Spain to adapt quickly to changing waste streams, packaging formats, and legislative requirements.
Collaboration with Ecoembes
The definition of sorting criteria and performance targets was developed in close coordination with Ecoembes, a key system partner in Spain’s packaging recovery ecosystem. Ecoembes played an essential role in aligning the plant’s technical configuration with national recycling objectives and extended producer responsibility frameworks.
This collaborative approach ensured that the upgraded packaging sorting plant Spain meets both operational needs and broader sustainability goals, reinforcing the effectiveness of the entire recycling value chain.
Preparing for future regulatory and market demands
European and national regulations are increasingly focused on higher recycling rates, improved material quality, and traceability. The modernized BZB facility is designed to meet these expectations while remaining flexible enough to accommodate future changes.
By investing in a future-ready packaging sorting plant Spain, BZB strengthens its ability to respond to market fluctuations, new packaging materials, and stricter environmental standards without requiring further structural overhauls.
A reference project for Spain and beyond
This modernization project stands as a reference for upgrading legacy sorting facilities across Europe. It demonstrates how long-standing plants can be transformed into efficient, automated, and sustainable operations through targeted engineering and close cooperation between technology providers and plant operators.
For STADLER, the project reinforces its position as a leading supplier of advanced sorting solutions and highlights its long-term commitment to the Spanish recycling market.
Strengthening the circular economy through innovation
The renewed BZB facility represents more than a technical upgrade. It is a tangible contribution to regional sustainability, resource efficiency, and climate objectives. By delivering a state-of-the-art packaging sorting plant Spain, STADLER and BZB jointly support the transition toward a more resilient and circular waste management system.
As packaging volumes grow and recycling requirements become more demanding, investments like this ensure that local infrastructure remains capable, competitive, and environmentally responsible for decades to come.
