The Port of Trelleborg, Sweden’s largest Ro-Ro port, is setting a new standard for sustainable construction. As part of its expansion, the port incorporated 87,000 tons of Sysav’s “Slaggrus,” demonstrating how waste can be transformed into a valuable circular resource. This high-performance material effectively replaces natural crushed rock while significantly reducing CO₂ emissions.
Using “Slaggrus” in Sweden requires compliance with strict site-specific guideline values. The Port of Trelleborg is one of the first locations permitted by local authorities to use it on such a large scale. This pioneering project showcases how innovative, waste-based materials can contribute to climate-positive infrastructure.
Thanks to its circular approach, the project avoided approximately 5,000 tons of CO₂ emissions, verified by RISE (Research Institutes of Sweden). Beyond sustainability, “Slaggrus” delivers excellent cost-efficiency. As a locally produced material, it provides a sustainable, cost-efficient alternative to traditional construction aggregates without compromising performance.
Its durability and stability make it ideal for infrastructure projects. The Port of Trelleborg expansion is more than a regional milestone—it represents a bold step toward a greener, resource-efficient future. This project paves the way for a new era of sustainable urban development by scaling circular solutions, proving that climate-friendly construction is a reality today.
This project is a prime example of how residues from waste treatment can be repurposed at scale, setting a new benchmark for sustainability in infrastructure development.
